speedo

could i calibrate this to fit on 14" tyres,
would this one work? if not, could anyone suggest a speedo?

Looks like the 2nd one would work,

They would both work just fine, you just have to attach the magnetic trigger to your rim or your sprocket or your axle and it will tell you in the instructions how to calibrate it for any tire size. if you bought both you could set up one to indicate speed and the other to indicate engine rpm.

I have a bicycle speedometer on my minibike

, and I had some trouble with it:
First, the speedometer got crazy when I started the engine, it was because the ignition was disturbing the meter I guess, because when I fitted a new spark plug contact, that problem was over...

And then the meter went just fine, just up to 50mph
Then, the meter couldn't count the wheel rpm, because I was going too fast and my wheels are too small...

I used this one on my kart. Merely had to measure the circumference of the tire. Put it in in mm into the computer and I have been off great guns since. I glued the magnet(which stuck itself onto the wheel pretty well as is) with 2 part epoxy have not had a problem since
iRenaat sweet mini bike, love the look of it.
