[Stevie69]

Hello..bought an electric unicycle..can't remember the type but it's the black and red one that's not to expensive..its been fine for a while but now when you switch it on the lights come on but there's no beep and the gryroscope doesn't work and the wheel doesn't spin..can't see any loose wires inside.any ideas?thanks..

Maybe posting some pictures of the wheel and it's inners (controller board) would help to identify the make and model and provide some suggestions as how to proceed further.

Nothing worth reporting happend between the last successful ride and now?

You have a multimeter and know how to safely do some measurements - then some data from the internals could maybe help to bring up some ideas...

Mabye un- and replugging all connectors could help? (especially in case between then and now quite some time elapsed)

I assume there is/was nothing smelling burnt and the motherboard looks fine (no burn marks, blown mosfets, etc...)?

Is the wheel stuck or does it just not spin up by the motor?

You followed the three thick wires from the motherboard to the motor? - sometimes their insulation abrades where the enter the hub/motor
