Only 30 bucks.
Might be fun to play with.
What do you guys think?

That's awesome - good way to raise interest in dhing and make it a more spectator friendly sport.THRILLSEEKA said:We just asked our local Sheriff and he gleefully accepted to come out and "shoot" the racers. Top speed of the day won a new Boxxer WC. Pretty good day!

trust me, i've tried..... A LOT
So if that's the case, how do radar guns manage to pick up a baseball going 90+mph?manimal said:it is nearly IMPOSSIBLE to pick up a bike with a real radar. not enough metal for the beam to bounce off of.

jcook90 said:best way is just a GPS. i rode w/ a guy who hit 47.2mph at plattekill, tracked w/ a gps, going down some killer loose rock trail down a ski run. plus theres nothing much more accurate than GPS, other than maybe radar
i did. typical police radar will only pick up a small signature of a bicycle, barely enough to lock in. if you've ever run one, it is based off of the dopler principle and it has a speaker so you can hear the tone. a small car has a weak signature even if there are no other cars around and a bike will come and go. i've had coworkers try to pick me up on it when i was doing well over 30 down a hill and they couldn't get a lock on me and i've never been able to pick up riders myself. i usually can't even pick up a moped unless it is the ONLY thing moving in the area.THRILLSEEKA said:And whoever said radar guns don't pick up a bike???? WTF??? Try not to forget the 160 pound average rider ON the bike? I've gotten TWO speeding tickets on a bike. And the baseball comparo was right on. Nice job.
i think something isnt quite right with that impression.THRILLSEEKA said:Actually, civillian GPS is NOT very acurate. And computers are a friggin joke. Everytime you lift your front wheel it accelerates, therfore throwing off your time.
Unless you manual the entire course a computer will be very accurate, How much could the wheel actually accelerate/decelerate in the few moments its off the ground? If you're really concerned about it put the sensor on your rear wheel, it spends more time on the ground. Oh wait, if you skid alot your speed will be zero, so I guess that wouldn't work either.

unless you lift your front wheel by swiftly moving your mass center back while pushing the bike forward, at the same time you raise the front wheel.
and even then, i wonder what the magnitude of radial force exerted on the wheel would be and how much energy you´d be actually converting into the wheel´s I.
lol, the other day i was at the djs, and there was this big double some guy was mussing to gap, and i heard the big shot of the djs on velocity and conservation of energy.Kornphlake said:Unless you manual the entire course a computer will be very accurate, How much could the wheel actually accelerate/decelerate in the few moments its off the ground?

We got that "impression" by running a course 4 times. Two of them I hit every booter and gap and two ladder drops. The other two I bypassed all the airborne obstacles. Due to the way they had the runouts for the gaps, bypassing was much faster, yet the comp showed that apparently hit 54mph on the airborne runs. 54 off a 15' double or a 5' ladder drop? Maybe that guy at the DJs and his "crapload of speed" is onto something? lol...ALEXIS_DH said:i think something isnt quite right with that impression.

ROFLMAO!!!!!!!!! I'd have given anything to have seen that whole experiment!it is nearly IMPOSSIBLE to pick up a bike with a real radar. not enough metal for the beam to bounce off of.
