bicycle speedometer for a mtoorcycle ???
Hey guys, so my zs250gs doesn't have gages and I came across a video on youtube of a bike with a bicycle computer adapted on a motorcycle. Excited I went to wallmart bought a 20$ BELL computer and put it on my bike. Well aparently it doesn't work quite well. Works fine up until about 15 mph, then I guess that the wheel spins so fast that the sensor does not recognize the pasage of the magnet that I place on the spokes.
I'm wondering if getting a stronger magnet from radio shak would solve the problem ??? http://i1228.photobucket.com/albums/...0811165150.jpg http://i1228.photobucket.com/albums/...0811165139.jpg |
Is the gap the recommended distance? If it's too far away it will lose the signal.

The speedometer should work well beyond any China bike speed. As Stew says, the distance from the magnet to the pickup might be the issue.

I've seen people use bike speedo's with good success. ONE caveat is that you may be getting electrical interference from the ignition system. I've seen this be a problem with motorized bicycles. Make sure the magnet gap is tight, and that the wires are not too close to the ignition system, and that you are running a resistor plug.
A way to check would be to run the bike to speed, kill the motor and pull in the clutch. If the speedo works correctly that's your problem. :D |
The bike speedos work great. They need a back light to be usable at night. I have a computer on my bike and I installed the magnet on the brake rotor. The pick-up is on the fork leg. It does have to be very close to the magnet to work.

Cal25,
A photo showing how you attached the magnet to the rotor and pickup to the fork leg would be nice. Thanks |
I will see what I can do for ya.

Well Speedometer works perfect until 19mph, as soon as I go faster it actually shows that im slowing down... Thought it might be because the magnet is spining too fast so maybe with a stronger magnet the sensor would be capable to pick it up. Went to Radioshack and got 2 rare earth magnet for 1.99$ . put one on the magnet and no problem until 60 mph, faster the same problem happens. Now I put a third one on the wheel see if that changes something.
Anyway here are a couple pics of my setting : ( and by the way no prob with cables cus I got a Wireless Computer jejeje fancyyyy 14$ at walmart ) http://i1228.photobucket.com/albums/...0911155542.jpg Here is the SENSOR that I put on the brake caliper : http://i1228.photobucket.com/albums/...0911155448.jpg And here are the magnet on one of the spokes of the wheel : http://i1228.photobucket.com/albums/...0911155502.jpg |
Nice, but dont they have to be calibrated based on magnet position and wheel size?
|
It is set by the circumfrence of the wheel.

Bicycle speedo
Intresting Subject - Keepup the info - I saw one of these just last night at wally world and was wondering if they would work? I saw someone on utube having done this successfully. NEED MORE INPUT! LMAO
Andrew :lol: |
Mine works great on my bicycle but I never been able to get the pickup close enough to the magnet to work on one of my motorcycles. I'll try the ideas suggested in this thread because they are super accurate when calibrated.have many functions, and are very inexpensive.
|
I'm using one on an ATV, and it certainly reads up to the point where I'm not prepared to go any faster. :lol:

SPEEDO
Any secrets you want to share weldandgrind?

He only rides at 11MPH. When an 8 year old girl outruns him he slows down. :lol:
Just kidding! 8) |
