May 20, 20241 yr Hi , my name is John,I've got an E-Bike Plus folder 24v . My pedal assist has stopped working, it's a fault with the controller, I know it's this because my wife has got the same bike and I've swapped controller over and works fine. I cannot get a controller anywhere,it's a Tianjin Santroll 24v model B-WZKD2413KA-JM101-1-F4. anyone got any ideas please
May 20, 20241 yr There a a few currently for sale on eBay, but they are ridiculously expensive for what they are. Maybe you should think about upgrading your bike with more modern components.

And would be cheaper. There are many options for alternatives depending on your knowledge and skill. Can you solder connectors and/or do basic bike maintenance, like removing a crank?

May 20, 20241 yr I forgot to say that I'd be fairly surprised if there were something wrong with the controller on that bike. It might be an idea to test it before doing anything. All you need is a multimeter and about 5 minutes work. What are the symptoms? "Stopped working" doesn't give any clues to what's actually wrong. Another reason to test the controller is that the fault might be elsewhere that causes your new controller to fail, so it would be good to know what's wrong. Also, the circumstances at the time of failure would be useful. Did the motor run intermittently, make a grinding noise, conk out while riding, or did the controller do the impossible and destroy itself in a warm dry garage while you slept, like most seem to do on this forum?
May 20, 20241 yr Ok, what sort of controller would you suggest? We need to see the wires and connectors. You didn't answer my question! Until you do, I can't help further with a recommendation.
