Hi I’m a newbie. Borrowed an elec folding bike ( I live on a Narrowboat), but the speed control on handlebar broke. It’s an old bike with a Tongsheng accelerater handle. I’m looking for spares to fix it

Hi welcome
Ask around the forum with a pic as a lot of people don’t look in the intro section

Hello Barbara,

Is this your throttle?



if it is, you can replace it with another throttle, not of the same make.

You won't get Tongsheng branded one as it will be OEM supplied item, however as Woosh say's any generic model will work follow the cable and check how many wires there are if only three then any generic 3 wire twist throttle will work. Some throttles with extra functions have more wires so check how many wires before you buy one.
The only thing you need to do is to make sure that the wire sequence at the connector is in the correct order other wise it won't work and you may cause damage if the positive and negative are connected wrong. Sometimes the pin wiring order may need changing to match the sequence on the bike.

This one comes with the wires and connector separate so wire canbe inserted for correct sequence.
