The individual is apparently otherwise fit and active and wants to get into
cycling if possible.
Thus, my question to the group... is there such a two wheeled bent? Has
anyone seen one factory or home-built? Is this a ridiculous/unrealistic
objective -- can't imagine how one would do both steering and powering a 2
wheeled bent but that is just my limited experience showing. Is there a
trike option that might be worth investigating?
Sorry I don't have any further info on the person's experience. I think the
limited functioning of the arms is a life-long situation, not the result of
a recent accident.
I agreed to ask around. Any ideas appreciated.

Also, come to think of it, haven't Shimano come up with a Nexus hub and auto

Hope this helps.
The ideal Platform for this chap would be a Delta Trike like a Kettweisel or
maybe an EZ-3. USS would be too twitchy for foot steer, so the EZ-3 would be
easier to alter. It would be easy to adapt the mono front wheel steering for
foot use and have a Mid Drive Motor assist to replace the cranks. Braking
would be by Discs activated by his feet or better yet the outerside of his
knees pushing against a spring loaded panel.
A Thought....contact Julie Kennedy @ APAX in Ottawa and see if their
Prototype Delta can be altered for his needs.
Hmmmm I thought APAX was due to be Unleashed to the masses by May 01, 03???
Anyone hear what what is going on with APAX (this time)??

In what way is it cycling if all the propulsion comes from a motor and
the driver, sorry, rider just steers and brakes it? It just sounds
like car driving to me.
Anyway, I'd have thought you'd need to go for a trike and something
that's lean steer with back-pedal braking.

One could adapt an EZ 3 to be steered with small servomotors. Braking
could also be done with motors or using one of the internal geared

brake. However, it is only a 4 speed.

I'm not sure about the armless ones, but my mate Bob is a keen cyclist

What benefit - you assert there's a benefit, but what more benefit do
you get sitting on a motorised bike than you get sitting in a
motorised car? I'd like to know, but you haven't made any suggestion
yet as to what the benefit might be (beyond asserting that it will
apply to the whole body).

And so on. Your idea of a full-body workout seems to be getting up
out of a seat, looking around, sitting down again. Now, I'll admit
that if that is the case a few miles on a motorised recumbent will
indeed be a pretty tough workout, but for most people standing up is
not major physical exercise.
But howcome? Why couldn't we rig a ratchet in the return chain idler and
use that to actuate, by backpedaling, whatever standard brake setup we
wanted to use - caliper, drum, disc, etc. This would tension the return
chain between the front chain ring and the idler, leaving the rear
derailleur assembly alone.
The function comes at some cost. First, the ratchet will introduce some
friction when the chain is travelling normally. Second, noting that in the
typical bent, the return chain turns around the return idler (if it's
present at all) at a very shallow angle, a second idler might be required to
make the chain run securely under all conditions.
Two questions come up:
1. Does anyone know of an instance of this mechanism?
2. Why not?
Unless someone else owns it, I hereby place this terrific idea in the public
Hmmm. Sounds like a nifty addition to the back wheel of my GTO. The return
side of the chain goes right past it, and ...
I'll get on it as soon as I get my shop, lathe, Bridgeport, and welder.
As for the Leg Muscle workout, remember that the male is using his feet to
steer with (not pedal). His legs would need to stay fairly rigid and
straight for long periods...try sitting in a chair and extend both legs
straight out and hold that position for 30 minutes with only the arch of
your feet on a bar/pedal to support your legs. With legs straight and rigid
the rest of your body is in motion on a trike (unless) you have mega
suspension and the EZ-3 has no such suspension...remember the legs have
replaced the pilot's arms and hands.
Also note we are dealing with an EZ-3 Delta trike with a Hub Motor inside
the front wheel. This motor has added 12 pounds of weight just to the front
wheel and this is 12 added pounds for the legs to be steering.
The Hub Motor will need approx'ly 42 lbs. of SLA batteries in the rear
carrier. The EZ-3 is now NOT a lightweight Delta and the heavier it gets,
the harder the leg muscles will need to work to maintain a straight driving
I regularly take my E-Motor powered tadpole out for a ride and I am using
more muscles on the trike than on my E-Motor CLWB.
As for your thought that it is no BIG deal getting into/out of a trike
seat....have you tried doing it?
Better yet...since this male has zero arm function....have someone tie your
arms behind your back and then see just how easy you get into/out of a trike
seat, lift up your legs and position your feet on the pedals used to steer
your delta with.
And YOU really think that you push back against a car seat with the same
force as you would on a bent trike....good grief, how many times Ian have
your tipped over your car in a turn? In a turn you need to push back hard
and then shift your weight to the side...no point in falling off your seat
(since you don't have any arms) to grab onto your frame with.
Don't know what kind of car you drive, but comparing a car to a E-Powered
Delta recumbent trike with foot only steering is cockeyed.
I guess the only way to settle this would be for you to get an EZ-3....go to
see Fast Freddy Markham at Easy Racer and tell him you are a really good
friend of mine and that you hate his Stiletto design more than I do and then
tell him you wanna borrow an EZ-3 from the warehouse because you wanna rip
it apart and stick a front wheel motor on it for a test ride....Oh and
you'll need to get both your arms broken first, but I figure Fast Freddy
would be more than happy to do that for you without you even asking him too.
BTW how is England treating you since you left Rhodesia?

Yep, like driving a car, where you keep your feet fairly still for
long periods, just making adjustments to pedal controls.

Whenever I sit in any chair I rest with my feet just supported at one
point. I guess maybe you have padding under the whole length of thigh
and calf to hold your legs up for you?

You mean besides my daily commute in a Trice Xl (eXtra Low)? Just

As a bent trike you're not propelling with your feet - absolutely.

Oh ho ho. How is Jericho since you left?
What got me seeing red was you are attacking the use of the E-Motor and
trying to show that a bent so equipped is the same as a car....and you took
some annoyance at my point that (everyone) bent will eventually slap a motor
on their bent. HPV purists get their shorts in a twist when one suggests
that (someday) they will be reduced to mere navigators of a power assisted
cycles....but reality bites.
Someday you too will be looking into a power-assist unit...you might go
kicking and screaming into a power-assist and you might be 89 years old and
peeing into a bag, but you will still (need) a P.A. if you wanna stay mobile
People get the wrong image of a P.A., they assume that once the P.A. is
attached that they'll never use their cranks again. Yes there is that urge
for many, but most of us do pedal as much (if not) more than before...just
that the strokes are not as hard.
As for my disagreeing with you because I assumed you were an ignorant little
git. I wasn't attacking you because of what you said...well maybe a bit, but
I (may) have had more experience working with the physically challenged to
support my points than you have had.
So ya wanna stick with our current debate or do we slide into arguing

Nope, you said "As for your thought that it is no BIG deal getting
into/out of a trike seat....have you tried doing it?" You will
observe not one mention of delta/tadpole in that statement. "A trike"
is as specific as you made it.
Nor did you specify climbing into a delta rather than a tadpole in the
relevant part of the preceding post.
Besides which, are you actually trying to claim that a tadpole is easy
to get into / out of and a delta is a whole body workout?

It may well be easier for you to disagree with things I haven't said
rather than what I have said, but doing so is lying, and it's not
nice. I have made no comment whatsoever about you saying everyone
will put a motor on their bent. In fact, I haven't noticed that
particular claim in this thread. Please either provide a quote and
message reference, or withdraw your false report about what I have

That's not what you proposed though, is it - you proposed a motor for
propulsion, not for assist - you've said "remember that the male is
using his feet to steer with (not pedal)". You've explicitly proposed
that the motor be the exclusive means of propulsion - this person is
not going to pedal. Make your mind up what you're arguing about.
> So ya wanna stick with our current debate or do we slide into arguing
I'm unaware of saying anything in this thread about politics. Do you
enjoy making things up and then either stating or implying someone
I'm still waiting, by the way, for a credible explanation of how
riding a bent where the propulsion is exclusively from a motor gives
one a whole body workout. Are you ever going to answer?
I'll go back and read what I wrote to Ron just in case but still remember
that I was talking about an EZ-3.
Too late. Bullseye (the crank and hub people) produced a lever and
ratchet mechanism that attatched to their cranks that would (with
correct fittings) pull on one or more brake cables when the cranks
were back pedaled. I don't know if they're still made, and Bullseye
no longer maintains a web presence.
Is there anyone in Burbank, California that can walk over to Bullseye
and ask them?
I was an instructor in Special Physical Ed for several years and I
know that many people with handicaps won't let anything stand in their
way of doing things like this. I know a guy with cerebral palsy who has
no useful leg function, but he commutes 15 miles a day on a recumbent,
hand-cranked tricycle. He can't speak more than just a little bit, but
carries a voice-generating keyboard with a cell phone and can make calls
when needed. That tricycle is his ticket to freedom and the joy of
rolling along under his own power.
When he gets to work, he does things on a computer that earn a very good
living. He could do this all from home, but does anyone not understand
why he chooses to take this arduous journey every day?
