I thought I'd try a road bike last weekend to see how it compares to my Trek
hybrid as I'd not ridden anything similar since the 1980s when they were
called racers, and while it initially didn't seem that much quicker or
easier on the road, as soon as I got back on my bike the differences were
quite apparent. I've now ordered a Trek 1.2 which should be with me in a
week or two once the finance department at work pay for the Cycle to Work
voucher.

Secondly, having done lots of 20 mile rides recently I thought it was time
to push myself a little harder and did 29 this morning with a trip to
Worcester and back. As you might have noticed it was more than a little
windy today which wasn't fun on the out let but at least I had it to my back
for the return. I'm pleased with the 14.5 mph average speed I managed, and
I'm looking forward to seeing how the whizzy new bike compares.

Woo hoo! Release that inner MAMIL :-)

(I was wondering at one point one becomes a MAMIL. I've been a MIL since
I was a teenager, so is it simply an age thing?)

We've spent the day preparing for a tour in the Western Islands. No wind

I've not tried a road bike but they do all look so sleek and shiny and
they're the majority of what bike shops seem to be selling these days.
Part of me wants to drool all over them. But then on most of them
there are no mudguards so if it's wet you have to have a change of
clothes at the other end, and there are no mountings for a pannier
rack so you can't take any stuff with you, and, and... [*]

In the unlikely event I found myself racing (but if that happens I'll
eat my hat) I would go for a shiny `road bike', but they're just too
far from a medium point to make them a bike you can use for almost
anything. Or at least that I could use for almost anything without
seriously changing my lifestyle to accommodate the bike, which seems
the wrong way around.

I suspect my current bike purchasing quest is turning into an attempt
to work out where the happy point is between zoominess and
practicality. But the impractical things are sooo shiny...

(S)

[*] Having got that set of whinges off my chest I find that the Trek
1.2 does actually have mudguard and rack capability so I'm being
unfair in this specific case :-)

Yep. They're beautiful (I was leering at a very sleek Specialized
earlier today, but not the MAMIL rider!), expensive, and
uncomfortable. If I buy a new road bike, it'll be another Dawes Galaxy
class machine like my current one, which is fast approaching 20 years
old and giving me no trouble at all.

Or you could buy a 2 wheel recumbent in a sporting configuration.
Long distance comfort and a reasonable turn of speed.

My Bacchetta Giro is a bit on the heavy side being a commuter/tourer
and carrying the odd kitchen sink but there are lighter ones. Even
the fancy Corsa can fit mudguards and a seat bag that takes a fair
chunk of stuff.

I think 'bent because mine has been neglected lately.

My work commute is now Brompton and train which fits better into my
timing and situation than the long commute on the 'bent did.

But I have taken it out for a general jaunt on the last couple of
weekends and it really is such a lovely thing to ride. Fast and
comfortable and I don't want to stop.

The Brom gave me a new appreciation of wedgies, but If I could only
have one I suspect the 'bent would get the nod.

Oh, yeah - I've wanted one for years, after trying a friend's. I was
thinking more of replacement for the Galaxy if/when it falls apart,
while a 'bent would be an additional steed.

>My work commute is now Brompton and train which fits better into my

I'll be in a new job quite soon, waiting to find out what the commute
will be (location is not yet fixed). I may be going foldup bike+train
too.

>The Brom gave me a new appreciation of wedgies

... is that a language clash, or is the saddle *really* uncomfortable?

Heh, language clash, "wedgie" being bent rider slang for an diamond
frame bike.

Oddly the Brom was the first upright I've ridden in ages which was
comfortable stock. I was quite surprised I was expecting to hate the
saddle but I did not.

Then I decided to try Brooks because world+dog was going on about how
wonderful they were and was that a mistake!

After a lot of faffing about and getting an adapter I was able to
make the B17S vaguely comfortable, and after more faffing about and
some uncomfortable journeys I could do without the adapter so
bringing the saddle a bit closer to the bars.

Then I lucked into a B67S which is a lot wider and more comfortable
and I'm happy now. Don't really need the springs, the Brom's
suspension works quite well, but the wider saddle is most definitely
better for me. The original Brom saddle is padded and has a much
wider range of adjustment. I think the B67S is better than the
original which is better than the B17S. I expect this is to do with
me being short and the Brom's very unadjustable riding position.

THe Brom is reasonably comfortable now. For a wedgie.

I wouldn't want to do long trips on it if the 'bent was available
though. In fact I wouldn't want to do long trips on it. As a
commuter yes, as a tourer I'd prefer the motorcycle if I didn't have a
'bent.

In my experience, most of the cheaper road bikes do have at least mounts
for a rear rack. (To which one can also add either SKS Race Blades or
Crud Roadracers.) It's not until you get into the >�1k carbon creations
where this stop being true.

Recumbent? Generally a high degree of zoominess (at least until things
head uphill for a protracted period), and may score well on practicality
depending upon the judge! Not so good on getting carried upstairs IME,
but less need for specialised clothing for long journies ...

The Giro 20 & 26 could be wound up to semi-serious turn of speed, and
(legs and hill permitting) kept there for quite some time without undue
effort. But the Corsa (Corsa 24 to be exact) was the closest I've come
to the instant acceleration of a road bike on a recumbent.

> I think 'bent because mine has been neglected lately.

I'm kind of wishing I'd not got rid of my last one, even though I'd come
to the conclusion it wasn't the one I really wanted.

I assume so.
I started cycling when it became apparent that running to the staff canteen
to grab a free cake didn't expend more calories than the cake provided, and
I needed to do some more exercise before I turned into a middle aged blob.

That was with a couple of years to go until the significant birthday, and
I'm now 6 months away.

For me, biking is very much a leisure and exercise pursuit, so I can be
selective about where and when I ride.
The road bike will be very much for pleasant [1] evening and weekend use, so
won't need any more luggage than I can fit in my pockets, and will probably
stay at home if it's wet.

The hybrid will stay around for winter and rougher use, and that has one
mudguard at least :0)


[1] weather, at least. The exercise may be less than pleasant.

I'm just jealous 'cause my best average (term?) is high 11s~12 mph
(over about 16~17 miles).

Perhaps none of the road bikes I've seen in shops have been the
cheaper ones, then, although most of them weren't carbon.

Has to have its own specialised clothing in that the recumbent rider
is well advised not to wear loose shorts.

General opinion seems to be that if a Brooks suits your bum it will be
okay when new and great when worn in, and if it doesn't suit your bum
it will be uncomfortable forever.

Unfortunately, you can also change so that a Brooks saddle no
longer is comfortable. Not usually a problem for those under
50 or with large amounts of adipose tissue.

*wince*. But surely recumbent riders can safely use normal underwear
without any of the potential for damage that vertical riders are
subject to?

Oh yes, but there have been Incidents.

After all, the middle aged male is rather prone to wearing their
favourite underwear until well past the point of no return.

I have specific but not specialised clothing. Boot trainery things
(only laced up as shoes though that way I can take the ends of the laces
behind the tongue and loop them through the speed lacing hooks opposite ),
an old pair of combat trousers(complete with braces), and one of the
boys old over the head jacket things. Come summer I will be in trainers
shorts and T-shirt. I also wear around my neck(at all times) a buff, a
baseball hat (Dull Men's Club)and eye protector/sunglasses (depending
on which lenses I have in) things.

I have always had strong legs, but can do NOTHING like that! The limit
for most people is aerobic capacity. I used to be able to do 15 MPH
for (say) 20 miles on the flat, no wind etc., but have dropped to below
6 MPH - all right, that was 60 miles and 3,500 feet of climbing :-)

I can't maintain more than 100 watts for long periods, and the bicycle
makes a huge difference to me. I need to be fully upright to maximise
aerobic capacity and stretch my legs each stroke at a low cadence to
minimise knee problems. Very like walking up a steepish (very steep
by cycling standards) hill.

Nick Maclaren.

I too like to be fully upright mainly because I look about as I go along
I find that the 'a�"$-in-the-air' attitude means I can see nothing. As
to cadence I am the exact opposite to you I like a very fast, almost
spinning, one, partially as it feels easier, and to me, it is kinder to
the knees. I use the 'legs extended but not locked out at the end of
each stroke' positioning

It has to be a tricycle - I can just (but only just) handle a long
wheelbase recumbent, because of my balance. I am very seriously
considering buying an ICE recumbent for my retirement, but Cambridge
is not an area that I would like to ride one around. That is why
it would have to be a folding one.

I've seen many trikes and a couple of recumbents three-wheelers
bimbling up and down Hills Road over the years, they don't seem to be
any worse off for the extra width.

Yes, but my commute is currently from opposite Scotsdales to the centre,
shortly to change from the former to West Cambridge. There used to be
some tricyclists and older riders, but the Trumpington Park and Ride
'improvements' was followed by both classes giving up. Given my
experiences, that might well be that they were intimidated into doing
so, essentially as I was. And a recumbent tricycle is VERY susceptible
to being run into accidentally on purpose.

The ride from Trumpington to West Cambridge via Grantchester and Coton
is gorgeous should you find yourself able to use that route as a
commute.

I used to use that fairly regularly as my cycling route to West
Cambridge, but the multiply damned Trumpington Park and Ride

I may try it again, because the Addenbrookes Access Road may
have reduced that effect. There is one truly horrible location
for cyclists, which is coming down from Coton onto the Barton
Road roundabout, with the M11 traffic theoretically giving way
to your left.

I forgot to mention that I am also interested in recreational

in the less populated parts of the world (including the UK), so
I definitely would want an "off-road" capable vehicle. My current

I've only tried it a few times, at either lunchtime or 5:45pm and it's

The problem is how many of the drivers will get aggressive if the
cyclist isn't riding right next to the hedge, so that they can
overtake dangerously. Not merely is that on a StageRoach route,
many Grantchester inhabitants are a pretty unpleasant bunch.

I have short cranks on the 'bent and spin more on that than on the
Brom.

It's easier to do very low cadence pushing very hard a slow speed on
an upright because you can move the bike underneath you, on a 'bent
the bars move more and the plot is more unstable.

But at higher speeds I can get a hell of a lot of power into the
pedals on the 'bent because I can push against the seat.

I tend to hunch over on hills on the Brom, no idea why, it just seems
natural.

I think it's easier to put more power out on the bent for a longer
time but that's hard to measure. It's heavier than the Brom, I do
wonder what a light recumbent would be like. (Can't test one, they
are all too big for me.)

Over on the Bacchetta forum there's a guy who goes by the name of Crit
Rider who regularly participates in an unofficial criterium that often
gets pro riders turning up for "training". He's compared wattage
readings from PowerTap type kit and notes that on his recumbent he's
putting out less power for a given speed than the road bike riders
are. This is in a race where he's offhandedly talking about taking a
pull at the front at 30mph or doing a breakaway at 33mph.

Likewise - I *think* it's knowing the back wheel's ground touching
point is a lot further forwrd than on a 26"+ wheeled bike, so on an
uphill you feel as if you should move your body forward more. But I'm
not sure.

Yes. Based on my investigations, you would expect that, just as
you would expect that he can put out less sustained power on a
recumbent than upright (which might or might not include a UCI
crouch). My best estimate is that a recumbent will be faster
only for riders who can sustain 20+ MPH (on the flat etc.), but
the data I am basing that on are so inchoate that it is no more
than an educated guess.

That compares with my best estimate is that a road racer will be
faster than a traditional upright only for riders who can sustain
15+ MPH and can breathe effectively in a crouch. I have no idea
what proportion of people that last conditions covers, though it
is very unlikely to be less than 10% or more than 90%.

This ^^^^. The world's fastest self-propelled human person-type-thing
Sam Whittingham (who is excellent) has, IIRC, stated that on his track
bike he can - briefly - put out 2000W. In the Varna streamliner he can
only hit 1100W for a similar period. But the Varna will still go over
80 mph and not even Sir Chris is going to get a track bike within 30 mph
of *that* :-)

Ground speed or air speed? :-) (Speaking as someone who generally averages
not much above 15mph, if that, but had a 20mph headwind this morning.)

(For what it's worth, when I tried Mike Causer's Speed Ross recumbent
(on a day without wind) I was a bit faster than on my upright, and would
expect to be a bit faster still if used to it.)

On the flat etc. E.g. essentially no wind, not pissing down,
freezing, roasting, with a reasonable road surface, not too many
traffic lights or traffic conflicts, no gut rot, hangovers, or any
other special reasons to cause slow progress.

But that was for classifying riders. My remark about one being
faster than another was in actual use, with at least some hills
and/or places where you need to slow right down and speed up again
(like traffic lights and junctions).

>(For what it's worth, when I tried Mike Causer's Speed Ross recumbent

I can't be bothered with trifling differences - they are important
only to top racers and sad sacks. Recumbents are marginally slower
uphill and when accelerating, so you need more than a bit faster
on the flat to be faster overall.

Anyway, those figures are only rules of thumb, and individual riders
will vary considerably.

I'm faster on a recumbent than I am on a racebike. Maybe not in terms of
brief speed, but certainly in terms of average speed over hours simply on
the basis of increased comfort. On the drops on a racebike I *might* be a
little more aerodynamic than a highracer, but there's no way I'd be able
to stay in the drops for >6 hours (my nexk muscles would go on strike).

Round a ~70km loop in the Austrian Alps I was ~12% faster on the
recumbent but that's only at around 15mph. Of course, on what was my
local hillclimb course (2km of ~10%, with a nice pub at the top![1]), the
racebike was 26% faster ...

(The highracer also had the advantage that fitting the luggage probably
improved the aerodynamics!)

Yes, I know the plural of anecdote is not data ...

I'm sure that will depend on the recumbent. Even with the improved
comfort, I'd be very surprised if your average speed on something like a
Bike-E or a Peer Gynt approached your average on a road wedgie over any
distance.

FWIW once I'd got used to my Street Machine (touring recumbent, heavy,
built like a tank) I found that my cruising speed was faster than on my
old roadified ATB, but that my average speed was slightly slower over a
5 mile commute. That was largely (as Nick would expect once informed
that there were no meaningful hills) due to stopping and starting. The
SM does not accelerate well.

I bought a recumbent specific rack-top bag last year. The aerodynamic
advantages over a pannier were noticeable, as mentioned in my review:
http://www.cyclesportsuk.co.uk/product_reviews.php?products_id=8311

(I didn't pay anything like �112.49 for it, I bought it when it was on
offer).

THe Giro is slower than the lighter Bacchettas but it can get moving
fairly well when not weighed down by heaps of Stuff.

I find the Giro can get moving when asked.

The Giro and the Street Machine are fairly similar aren't they?

I do find the Giro 20 is better as a Giro 24 though.

I do notice the panniers... But usually because they are full of
heavy stuff. MOst of the time I just use a seatback bag.

Judging by a quick Google image search the basic configuration is
similar, though the Giro looks like a rather more basic design and seems
to lack the full suspension that the SM has.

Neither is anything like the Bike-E [1] or the Peer Gynt [2], though
(examples that I picked out as being particularly slow bikes). But then
they weren't built for speed. The Bike-E was built for city use (and
ISTR reading was the top selling recumbent of all time), the Peer Gynt
was built for laid-back touring (I quite fancied one myself until I read
a letter in RCN about 16 years ago from someone who had bought one and
been very disappointed to find out just how much slower it was than his
wedgie).

Both had the BB quite a bit lower than the seat, making them rather less
aero than a bike with a higher BB.

Luckily no. And the largest hill on my commute is 27m above sea level,
so when it's not windy, things are much easier.

What effect does suspension have on speed?

I have no idea as to what, besides weight, affects speeds on a 'bent.

Recline I suppose but how much does that matter?

Some combination of seat angle and tube angle affecting both rider hip
angle and aero? Hand position?

Bacchettas seem most common in the US (surprise) and StreetMachines
and other Euro bikes in Europe (surprise again) so dunno if there are
any races or trials that have pitted one against the other. Here in
Oz there aren't many 'bents at all. A number of Greenspeed trikes
(once more, surprise!) but other than those a scattering of makes and
the odd (very odd, you should see the thing) home made carbon whatsit.

I think I'd agree with that. I find that, on the same distinctly
non-flat route that's about 30% on urban roads with traffic, lights,
giving way at junctions etc, I average about the same on my
Streetmachine as I do on my DF tourer. The DF climbs slightly better,
and is certainly quicker in start-stop traffic, but loses out when
cruising on the flat/downhill sections. (Partially because I'm a lot
happier about high speed descents on a suspended recumbent, but also
because my DF has a very upright riding position, to reduce the load on
my wrists.)

For reference, I find the ICE Sprint trike about 10% slower than the
Streetmachine (I actually tested this vaguely scientifically with
equivalent tyres and seat angles), due to more rolling resistance and
poorer aerodynamics. Faster-rolling tyres improve things dramatically.

It adds weight, obviously. It should reduce energy lost to bouncing the
whole mass of the bike+rider up and down on rough surfaces (though I've
no idea how much) which means you can run tyres at higher pressures and
reduce their rolling resistance accordingly. More critically, it allows
you to be a lot more confident about marginal road surfaces - I can hit
potholes at speed on the Streetmachine that would cripple a lightweight
road bike. I've out-descended much more aero but un-suspended lowracer
recumbents because of this.

Quite a bit, once you're over about 20mph or so.

Bottom bracket height (relative to seat) is another - a higher BB
reducing your aero profile.

Of course changing either of those affects the biomechanics...


Being low to the ground brings in boundary layer effects - but I've no
idea how significant these actually are at the sort of speeds I'm likely
to achieve.

Hand position certainly makes a difference. Hamster bars being much
better than open-cockpit or under-seat designs, which both put a lot of
arm and handlebar out in the airstream. I find there are real gains to
be made by tucking my elbows in (on a USS 'bent) at speed.

Quite a lot. My Baron X-low has the seat cranked back as far as it'll
go. Plus keeping your hands/arms tucked in helps - I relocated the
brake levers under the stem and sawed the bars down as narrow as
possible. With a tail fairing I did 28.5 mph for 45 minutes on an
indoor velodrome and ~26 mph for two hours around a two mile motor
racing track on which all three straights had a headwind :-)

The big stars of Battle Mountain last year were Aussies from well-known
Mega-Global Corporation Tri-Sled. Ben Goodall just edged over 70 mph in
Nitroglycerin while Gareth Hanks set the first official trike record at
71.79 in Completely Overzealous. Designed and built in three weeks of
all-nighters. Photos of same may be found by poking around

"It depends".

As Kimble noted, over grot surfaces it makes the bike more sure-footed,
plus the lack of up-and-down for bike and rider as you hit the bumps
saves a lot of energy and that translates to potentially quicker. So
down a hill on a ruined sub-B back road in the middle of nowhere, quite
a bit. Around a velodrome, ~ damn all. In between there'll be a spectrum.

It's also the case that different suspensions are made for different
jobs. The sort of thing you find on a downhill MTB is there to soak up
enormous hits while the sort of thing you find on a Moulton is to help
even out small imperfections on normal roads. Both are good at their
own job and pretty hopeless at the other's. For the road, a properly
designed[1] road-going suspension will potentially aid speed but the
better the road the less significant it'll be.

It's aerodynamics in general. The Kingcycle Hachi was less reclined
than the Optima Baron, for example, but still contrived better
aerodynamics with a rather radical chain routing and over-the-shoulder
frame (I suspect Mr. L can provide us with better details on this sort
of stuff).

Ultimately, if you want to go really fast you put on a fairing.

Human Power Vehicle Association races have done this, but after earlier
days when folk would turn up on anything the fields appear to be getting
more specialised. Again, Mr. Larrington is the man for proper info here.

Pete.

[1] I've been talking about suspension, as opposed to "suspension", as
found on BSOs. That enables your BSO to go "boing" in an undamped and
not optimally useful way. AFAICT good suspension is non-trivial and
needs decent design and engineering input to come up with a well working
system, not just sticking a spring on it.

My first 'bent was an Orbit Crystal (aka Speed Ross). It was a quick
beast, notably quicker than my drop-bar tourer. In terms of overall
shape it was very similar to the Streetmachine, but unsuspended and
significantly lighter.

So partly it's an absolute like lighter and thus quicker to accelerate,
but partly in psychology IMHO. The SM encourages gentle cruising in
great comfort while the Crystal encouraged going as fast as possible.

If you're cycling beside a lowish hedge (e.g. one where you can see over
the top because the ground drops down away from the road to the base of
the hedge) in a strong crosswind, being low to the ground can definitely
make a difference.

That's a good point that I hadn't considered.

This is of great interest to me at the moment, as I'm seriously
considering buying a new bike next year. I have two (possibly
conflicting) requirements: I want something that's both lower
maintenance and a faster commuter than the Street Machine. And I'm not
interested in upright bikes - if I was I'd just get a simple fixie.

I've already reduced my maintenance load significantly over the last few
years by fitting Magura HS33 brakes, a ceramic rear rim and Gore Ride-On
gear cables. To go further I'm looking at my next bike having a Rohloff
Speedhub and hydraulic disk brakes.

My next bike will have both wheels the same size (to avoid the need to
carry two spare tubes). The question is, 20" (which will give me a
lower ride height) or 26" (giving me about the same ride height as the
SM)? DW has said that she'd rather I didn't get something lower, as she
finds the SM to be at a nice height for us to converse when we ride
together, but that's not a primary consideration (I'll still be able to
use the SM for family rides).

The aerodynamic effects of ride height aren't the only consideration
when I'm thinking about wheel size, though. I expect faster
acceleration with smaller wheels, but I also live in South
Gloucestershire, where road maintenance is merely something that other
local authorities are rumoured to do, which is an argument in favour of
bigger wheels.

I'll be visiting London later in the year, I hope to try a few different
bikes out at Bikefix and London Recumbents.

I live 150m ASL, and from here everywhere is uphill from everywhere
else ;o). The wind here is usually enough to take your breath away.
The trees/bushes etc are bent over with the prevailing wind, if (it
does happen honest) the wind is blowing in the opposite direction
it is fairly light 10~20 KPH and I do my usual route (16.5 miles)
backwards so the wind is at my back for the l o n g slightly uphill
bit. More normally the wind blows S-SW at about 20KPH the long uphilly
bit becomes slightly downhill (well it's undulating but the trend seems
slightly downhill) , and with the wind at my back I can get some (for
me, and on a sit up and beg hybrid) ridiculous speeds (mid 20s up to 30MPH).

Well, you can work out the acceleration improvement quite easily.
Just work out the proportion of the all-up weight you save,
remembering that rims and spokes count double. I doubt that it
would be noticeable.

My thoughts, which are probably worth precisely what you paid for them!

If you want both wheels to be the same size, and you want a performance
improvement over a Stretmachine then the obvious options occur to me
are :-

Bacchetta Giro 26 ATT
Bacchetta Corsa
Challenge Hurricane
Challenge Furai

Personally I had bad experience trying to get spare parts for the Giro 26
I owned after an accident, so on that basis *I* couldn't recommend the
Bacchettas (other people may have had different experiences of course!).
Both of the Challenges are available with a pair of weight reduction
options (Light Allround & SL-II)) and I think you'd have to pick one of
them to get the weight noticably under the Streetmachine.

Bacchetta themselves are usually very good about parts. Their
dealers can be worse... but if you can't get something from the dealer
get on to the US because they will send stuff directly.

I buggered up the adjustable stem adjuster on mine and nearly 2 years after I
bought it I emailed them to buy a new one. They questioned me about
how it broke and said I should have told them when it happened and
they'd have sent the new one for free.

While dealers might be a bit rough, Bacchetta themselves have a very
good rep for customer service and in my experience a well deserved
one.

<nods> I *almost* did go direct to Bacchetta. In fact it had got to the
point where I was at work thinking "I'm ringing Bacchetta and going
direct when I get home today", and then the UK distributer rang me before
I got home ...

I've heard similar (about Bacchetta being very good themselves) online,

The Hurricane was the most fun of all the bikes that I tried before
buying the Street Machine. I rejected it 13 years ago because the rack
was crap (it wasn't suitable for anything other than a racktop bag).
The rack design has improved since then.

The Hurricane is one of the bikes that I'm considering. I looked at the
Furai, but couldn't see that it had any advantages over the Hurricane.

I don't think I've looked at Bacchettas. Perhaps I should.

THe bod I know with a Furai uses a seat back bag. WOuldn't be enough
for me because I commute to work on mine so want to be able to take a
pannier. I can just fit the work stuff in my seat back bag but the
pannier is more convenient, just remove and go rather than fiddling
about getting the stuff settled.

Have a look. Yeah I am an unashamed Bacchetta fan! The Giro is a top
notch all around bike, the ATT ali ones are lighter than my steel so
think about those if that's important. Corsas are lighter still but
eyewateringly expensive, at least here they are. (And more to the
point for me they don't make them in the small sized frame)

http://www.bacchettabikes.com/blog/ has and article on wheel sizes
and frames which might be handy.

The bacchettabikes site also hosts a forum which is the place to
go if you want answers about Bacchettas especially about mods and
what fits what but they are all a bit one eyed... so bentrideronline
is probably better for comparisons rather than technical information.

I have been pondering one of the underseat racks but my cheap chinese
rack manages panniers OK so no real need for it.

Only rims and tyres (and rim tape) count double (near enough).
Spokes count about 1.5x.

(For the effective mass for acceleration only; everything counts 1x
for hill climbing effort. You know this but it bears repeating.)

Correction accepted :-)

Yes. And it doesn't make any difference whether you cycle or
walk uphill, or whether the pound is in your paunch or your pannier,
but pushing a laden bicycle is slightly less efficient.

The Corsa 24 (which they don't seem to make any more) was the closest
I've experienced to roadbike acceleration on a recumbent. The (rather
old) Hurricane I tried at D.Tek many moons ago was interesting too, first
and only recumbent I've tried where I kept myself upright whilst
stationary by putting my hand on the kerb!

Is that the standard Bacchetta rear rack or something you bought
seperately? I carried loaded panniers (in some cases with multiple
multi-packs of coke) on the standard rear rack without issue, and I've
seen a photo of someone who'd fitted a Topeak rear rack.

(I also had a Radical Solo Classic which was useful for the commute.
Even did a tour using only that as luggage.)

They don't?

Ah well, that makes theoretical n+1 decisions a fair bit easier. The
Corsa 24 was the only Bacchetta I've encountered that's acceptably
Kim-sized, and I was never particularly enamoured by the prospect of 24"
wheels (or open-cockpit handlebars).

I'm mostly lusting after the Challenge Fujin SL...

http://bacchettabikes.com/bikes/performance/corsa lists a 650c
version.

But only in the medium and large frames so no good for me.

X-Seam: Medium: 37"-46", Large: 41"-50"

(Although those sizes seem odd. My X-seam is 39" but I can't fit a
medium frame, seat more than halfway up the stick!)

My dealer (flyingfurniture.com.au) supplied it. I don't think it's
the Bacchetta one, it has no branding except some Chinese characters.

I haven't carried anything really heavy on it. It's pretty sturdy
though and I think could carry a fair amount. If I want to manage
something heavy I use the trailer.

Just had another glance round Bacchetta's website and there doesn't
appear to be any mention of the 24. :-( At one point in addition to
specifically mentioning the Corsa 24, they also offered the 24 as an
option for the (titanium) Aero ...

The 24" wheels (and the limited tyre options) where somewhat off-putting
to me too. The open-cockpit I wasn't too bothered about having had both
a Giro 20 and a Giro 26 ("Darth Kevin" very generously let me swap the 20
I'd bought from him for a 26).

> I'm mostly lusting after the Challenge Fujin SL...

... an entirely understandable lusting I'd say! The Fujin SL (or maybe
the Fujin Tour SL-ii?) makes the list[1] of things I'm considering for my
return to recumbents, but I suspect I may well end up with a Streetmachine
as plenty of them seem to end up eBay! (Of course, whatever D.Tek has in
stock at the time when I finally scrape together enough ���'s.)

[1] In no particular order the list consists of :-
HPVelo Streetmachine
HPVelo Grasshopper (FX)
HPVelo Speedmachine[2]
Challenge Fujin SL
[2] Well I say "no paricular order" but for some reason the Speedmachine
appeals! But it would probably have to be new and that means ���'s,
and the Challenge Fujin might be better value for money?

We're back to the functional classification of bikes thing, I think.

A Fujin SL makes sense to me as an n+1, as I already own a Streetmachine
(and a do-it-all DF hybrid). It's probably fair to say that you can do
most things on a Streetmachine, except going fast without gravitational
assistance. As such, something really quick and a fair bit less
over-engineered makes sense as an addition for audaxy type stuff.

If you're looking at only one recumbent (most sane people do), then I'd
suggest that some suspension (or big wheels a la Bacchetta) and proper
load-carrying ability would be desirable. There's a weather-related
argument for being a bit higher off the ground than a Fujin, too.

I've not ridden a Speedmachine, but the Grasshopper is functionally
similar enough to the Streetmachine to make the folding version very
attractive, if only so you could fit it in a normal sized car (I don't
find trains a problem with the SMGT, but I do have the boom slightly
shorter than the minimum extension). I actually think the Grasshopper
handles slightly better, at least when unloaded. Conversely, the
lowrider racks on the Streetmachine are less of a compromise, and a 26"
wheel does make the gearing simpler.

Heh....

There's a railway underpass I use now and then which is right next to
a river and floods at high tide.

I was out with some people one weekend and there was a king tide: the
water was high enough that it was over the BBs of the uprights and was
brushing the bottom of my pannier.

I rode through carefully, the upright riders complained their socks
got wet....

and the trike rider decided to walk it.

All of those bikes except for the Grasshopper have different sized
wheels. It might not bother you, but I find it a PITA to have to carry
two spare tubes.

I think if I buy another bike then I'm most likely to end up with the
Grasshopper, but a Hurricane is still a serious possibility. I also
intend to try out Bikefix's Raptobike Midracer, which could be a
definite contender if the front wheel drive doesn't prevent it from
having a reasonable turning circle at low speeds:

It all still worked afterwards.

I have rear and underseat on the Streetmachine. The underseats are less
used but if you're going touring are worth having, for a couple of
reasons. First, it increases the amount of shite you can cart about
(actually, that's not always a good thing!) but it also means you can
stick the heavy stuff between the wheels and under the rider so the only
real effect on the handling is gluing you to the road a bit better.

You need quite aweight on the back of the SM to start affecting the
handling but it does happen, where the lowriders are as close to neutral
concerning handling as you're going to get while keeping the stuff on
the bike itself (haven't tried trailers so I don't know how that'd
compare).

But if you're not carrying big/heavy then not really much point. Also
worth noting that the above endorsement applies to the Streetmachine
where the lowriders are between the wheels. On something like a
Grasshopper they're further back so I'd guess wouldn't be so neutral.

They have both plus and minus points.

The plus: they're the coolest looking bike luggage there is, actually
improving the appearance of a bike you hang them on; you can put long
stuff (tent poles, for example) completely inside; they have more
capacity than other panniers so there's less need to split stuff up
which makes packing easier, as do the very long access zips.

The minus: they don't come on and off easily. When we're touring Roos
generally leaves hers on the bike the whole time, including overnight
parking, as they're a bit of a fiddle to get in place; they only work in
pairs; though they do have compression straps they don't under-pack that
gracefully, or in other words if you haven't got a job that needs two
reasonably large full panniers they don't work that well.

Exec summary, excellent for touring, a sledgehammer/nut thing for
general day to day.

On paper it certainly look slike a dream, though my one time on a
Challenge (a Mistral, dog of a bike IMHO though the Maggies it had on
inspired me to upgrade my brakes) told me my back and their seat were
not similar enough shapes.

Moral of Story: you must try before you buy.

I do like the Speedmachine, though it'd have to be the Superman bars as
I don't get on too well with tillers. In general I'm a fan of underseat
steerers but that's my touring bias, and I think having a bike that
calls itslef "Speedmachine" which you proceed to hobble the aerodynamics
of is somehow Wrong.

I'm also rather ambivalent about the Bodylink seat (also a problem on
most other HPVels these days). While the adjustability is clearly their
main selling point the fact is that HPVel's old hardshell "Medium" size
fits me very well indeed and no amount of faffing about with the
variables on the Bodylink has got it any better than "not quite as comfy
as I'm used to". Bah!

For a stoopid n+1 the Nazca Fuego looks like it might be the thing. If
I replaced my Streetmachine due to disaster (that's the only obvious
reason I would) then I think a Nazca Fiero (as used by Roos) would be a
distinct possibility. It's a 20/20 (I agree with Danny's point that
carrying 2 tubes is a faff), it does the sort of thing I want, it's a
bit more fun than the SM (though not quite so good with loads or pilot
view, you choose, you lose) and it's good looking with a very comfy
seat. I tried a Grasshopper when Roos was auditioning, and neither of
us were wowed (nothing wrong with it, just not exciting enough to spend
all that cash on), while the Fiero put an immediate grin on both our
faces. We went to NL to try it, but Laidback in Edinburgh are a UK
dealer now.

Ah yes! The Raptobike Midracer should also have been on that list! Not
that I've ridden either form of Raptobike alas (I moved away from York
about a week before the lowracer turned up for the Velovision review!).
