Stopped for Speeding on a bent
Mike
gear. Their was a car on the side of the road ahead. Suddenly a police
officer jumped out of the car. He looked really supprised to see me on my
Baccetta Strada. He flagged me down and said I know that I can't give a
bicycle a ticket but you really should not exceed the posted speed limit. I
replied this is a bicycle it does not exceed speed limits. He said you were
going 30 mph in a 25 mph zone. I said sorry will go slower next time. Then
he told me that he was a roadie and was interested in recumbents, he was
riding a Cannodale upright but was looking at the Vision Sabre, Baccetta
Strada and Volae Club. I answer one of his questions how fast are they.:) I
let him sit on it and he liked the seat. I have only had a bent for one
riding season it sure gets a lot of attention and after working out the
initial bugs on the Strata it had been impressing me each time I ride it.

find that the radar gives a 5-10 MPH faster speed than what my dead on
computer is syaing. The reason! The radar is picking up the faster speed
of the spinning pedals. So unless you have a fairing covering your
pedals you could beat any ticket in court.
Sorry to burst your bubble. Ps there are calculations you can do to find
out the speed you are going at that gear inch and cadence just to check.
Thats how I know my computer is dead on ;)

have been the Police.
One traffic supervisor said to me last September that he has seen way too
many dead and mangled cyclists to ride one himself, but a short ride up and
down an alleyway he said he'd seriously consider getting a bent. Every so
often when I ride he hits the siren and pulls up beside me and says he is
still thinking about the bent idea. I figure it is an image issue. Maybe if
I can get one bent then more will follow & go bent.........Hmmm "A Bent

He's wrong, he CAN give you a ticket on a bicycle, I got one years ago for
right turn on red.

Yup, best way to get out of a ticket is to let them admire the bike for a
while :)

5-10 mph faster?
Let us check.
Pedals are rotating in a circle, the diameter of which is about 0.35 m (=35
cm, 1 inch=0.0254 m). If the cadence is very high, say 90 rpm (revolutions
per minute) , the speed of the foot is
pi*0.35 m/(60 s /90)= 1.6485 m/s
1.6485 m/s*3600 s/hour= 6.0 km/hour
6.0 km/hour/(1.609 km/mile)= 3.6 mph
At top position the pedal speed 3.6 mph is added to the speed of the bike.
At cadence 60 rpm the speed is only 2.4 mph, not much more than the speed of
a walking baby.
(At the lowest position it is subtracted. Astonishing, how small the speed
really is, typically about 15 % of the bike speed on flat terrain).

bike, it's complicated by the fact that speedometers are not required
equipment on bikes as they are on cars. Novices, at least, really have
no idea how fast (or slow) they're going. Besides, most police don't
want to bother with you if you aren't going at least 10 over. I think
in the original story, the cop just wanted to talk to the biker and
see the neat 'bent.

I doubt the radar was reading the pedal motion, much more likely it was
seeing the apparent motion of the spokes and miscalculating based on
that. Radar *loves* rotating machinery. Most of the radar returns on
aircraft I am told is from the big spinning fans on the turbo jets or
props. A lot of stealth technology consists of moving the engines back
into the body and running a carefully calculated S shaped inlet duct to
them covered with absorbing material - it shrouds the spnning fans from
the radar signals and vastly reduces the signature.
I've seen this first hand when a local police officer stopped by our
parachute club one day and amused himself with the radar gun. As one of
the pilots, I was well aware of the speed of the jump plane in various
phases of the takeoff, 45 mph to get the nose gear up, 50 to pop up into
ground effect, accelerate to 70 and climb = but he was getting readings
in the 80's while the plane was still rolling on it's wheels! The radar
was displaying a speed based on the prop rotation rate, but it knows how
to do is send the number it gets to the display, it's up to the officer
to distinguish what is good data and what is GIGO. Unfortunately they
have a terrible track record at that. He was quite convinced the plane
was going 85 as the gun showed, and wasn't going to listen to any other
source of information. ;-(
As far as beating tickets - nope. I got tagged one day on a motorcycle.
I'd just missed hitting a pair of deer, and doing a panic stop and was
working my way up the gears to cruise speed again when I came around a
corner by a country store with a car on my side of the road. It's cabin
lights were on, and in my jazzed up adrenaline charged state, I took that
to mean the door was about to open and someone clueless was going to step
out in front of me so I got on the brakes again. When I slid to a stop
the lights came on and I got a ticket for 55 in a 40 zone. I was doing
about 37 when the car came in view and was still in 4th gear. The radar
was either reading the wheel rate, or vibration from the fairing. Went to
court, showed my license to repair and calibrate those very radars,
explained why it wasn't right - and got told it didn't mean nothing. Got
the points, paid the fine. (and the next time those ruby red lights came
on, I made the officer work for it. He didn't work hard enough...)
In college, my roommate got ticketed for 37 in a 30 zone on a DF. He paid
the ticket, but then wore it proudly.
The small radar units like the MR11 and up are not the stuff their elders
were made off. Back in the day, there was tripod, a dish, and a plotter.
The dish made the beam narrow, the plotter made momentary abberations
obvious. Today the gun has a 3 inch horn with a half power beamwidth of
23 degrees. That means for about a 45 degree swath out in front of the
gun, everything is getting painted about the same. Those little gunsight
notches on top of the unit are frankly a joke, but the officers believe
the beam goes where they point and nowhere else. Out of this vast
illuminated area, a whole cluster of signals return, some showing fast,
some slow, some loud, some soft. The crude circuitry in the unit simply
finds the loudest, fastest return and puts that up on the display. That
might be you 100 meters away, or it might be that truck coming down the
hill a half mile behind you. If you're going 55, but that truck is doing
70, you'll likely get the ticket cause the officer thinks he's only
pointing at you, but the truck is well illuminated too, and makes for a
much louder return than your semi-stealthy sports car. Anything that
perturbs the beam momentarily, including surges in the car electric
system like when the airconditioning clutch pulls in, can get locked up
in the display as the highest speed. When NIST/NBS reviewed the radar
units for the NHSTA, they specifically recommended the 'peak hold'
circuitry be disabled on units used for traffic control. It will never
happen. The ticket rate would drop too much, and the officers would have
to watch the display, not write reports while the radar is running.
We used to try to do 1/4 motorcycle trap times with a friendly officer in
a defunct mall parking lot. He'd point the radar gun, and we'd accelerate
towards him. Sometimes we'd paint on the screen, sometimes it would show
7 mph of the little old lady turning her buick around in the lot hundreds
of meters away. The radar profile of the bike was much smaller than the
profile of the car, even though it was 2-3 times farther away. But it
only responds to the loudest, fastest signal.
Radar is more complicated than most folks, including the officers who use
it, think. If you want to get a good speed reading on a bicycle with one
- be sure there's nothing in the background of the bike moving, and you
may have to cover the spokes with an aero disc or something metallic to
keep them from confusing the radar's simple minded discriminator. Also
you need to be coming more or less straight at, or straight away from the
radar to minimize something called 'cosine error'.
I know, TMI. ;-)

Last summer, I was riding merrily(I really was merry...)and an oncoming
police car stopped and motioned for me to stop also. I immediately thought,
" Oh man, what kind of crap am I gonna get? "Too low." or "Get a taller
flag." or "we've been recieving complaints...". When I was even with his
window, he said " Where did you get that bike? My wife saw you ride thru
the neighborhood earlier, and she said THAT is the kind of bike I want."
I was on my homebuilt Tulpa trike. He now has a Burley Canto(?) and is
looking for another bike/trike.A few weeks ago I helped him fix a few
things that the dominately DF shop put together wrong. (For the locals, it
was the big Fort Wayne shop that starts with a "K".)
Never hurts to have a few cops as friends.

Do they actually give tickets for 3mph over the limit? Here a posted limit
of 60 means 65 or so before one MIGHT be stopped.

They don't give tickets *to cyclists* for speeding at all, but they /can/ do
you for "riding furiously". What constitutes "furious" is, I imagine, very
much in the eye of the beholder. As far as motor vehicles are concerned,
the rule of thumb appears to be 10% above the posted limit + 2 mph, so 35 in
a 30, 79 on the motorway, at least for Gatso cameras. Real representatives
of the Old Bill may vary - I once got away with a mild finger-wagging for
92.

No. Well, sort of. It is illegal to sell goods in imperial quantities with
the exception of milk and draught beer and cider. But it is also illegal to
put metric distances on signposts or to drive a car with the speedometer
marked in km/h only...
> 2. The cycle world speed record is 207 mph? Motorcycles, I assume.
On rollers. The /real/ cycle world speed record is 81 mph.
