    speedometer on scooter 3rd Oct 17 at 10:51 PM
    not sure if this is the right board, my son is 10 and autistic and is facinated with speed, he really wants a speedometer on his stunt scooter, we are looking at the bike ones and wondered if anyone knew if one could be fitted on a scooter. i know something has to be fitted to the spoke of the wheel but scooters dont have spokes, so not sure if that would work or if anyone knows of anything else that would work

    thanks in advance

    many "motorcycle" ones use a magnet mounted on the wheel rim (usually the brake disc) , the good thing is they can be set on a wide range od wheel diameters , however they are not 9.99 from argos nore have you a battery fitted!

    now the easy way , you can buy a magnet bolt , or indeed modify the thing that come with a cheep cycle one and glue/bolt it anywhere on the wheel , close enought to be picked up by the reciever (1/8th inch)

    It just a magnet that is attached to the bike spoke, no doubt it could be glued to the wheel somehow, and then there is the sensor which need to be mounted on the frame to detect the magnet passing by

    In the head unit you have to enter a setting to tell it the diameter of the wheel so it can calc speed - only issue might be that the wheel size is too small, such that there is no setting available to suit it

    Thats my experience from kids bike some years ago now , might have changed

    EDIT :
    Looks like you would be OK
    See A section on this doc for example

    Edit 2:
    Ah - They are very small wheels ! so above probably a non starter

    If you've got an old spare smartphone lying about you could run a suitable GPS app

    My sat nav has a function to display speed. He would also have a map.
