Does anyone know anything about brushed motors for electric bikes?

Question

I have a crystalyte sparrow brushed motor and for some reason by electric bike isnt working. Could it be that the brushes are gone. I only had my motor kit for 1 year and i did not leave brushed motor in cold. Could it be controller or throttle. Thanks

Answer 1

Take two

There could be any number of problems. The battery the controller the throttle, the motor, a brake switch, the on switch or the wiring.

I would be checking for loose wires bad connections, and blown fuses in the controller first. Then the battery. Sometimes a bit of dirt can get jammed in the brush holder or bend it

If you can get it beside one that works try plugging in your bits to see which one/s don't work

The sparrow is a brushed motor. Try your place of purchase or contact these guys for spare parts or repairer. The problem could be anywhere so it could be cheap or expensive. You could get brushes from an auto electrician if stuck. (The auto electrician may be able to fix it)

Answer 2

Yes more than likely the brushes are made to wear. Until they do not make contact with the commutator. Easily and cheaply replaced for about five bucks a set...
