Can you use bike speedometers for mini motorcycles?

Question

i have a 47cc mini motorcycle it does not come with a speedometer so i want to get one.

Answer 1

motorcycle speedos come with computer built-in... so i dont think that you will be able to connect it to a little fidy....

anyways..why u need a speedo on a fidy? it doesnt go fast....

Answer 2

Yes. Contrary to what others have told you, all good bicycle computers with speedometer are programmable for wheel size, with detailed instructions for calculating the factor to program.

I've had a lot of good experience with the Cateye brand.  The wireless ones will be easier to install.

Answer 3

Only if the tire size matches that of a pre programed setting in the speedo.

Usually bike tires are not the same size as motorcycle tires so I would be very surprised if it would work.  A bike shop might be able to tell you if your tire size is in the list of one of the speedo's they sell.
