Ebike controller Problem

Hi

New member

I am from Bonny Scotland, been running a 48 volt, 1000 watt kit from petrolscooter.co.uk for 4 years, I was down the beach with my bike and it just lost all power, iv done over 40,000 miles with this hub kit, its essentially a cheap generic brushless hub motor, with hall sensor, and the controller was as basic as it gets, but its fast, powered by a 22 amp hour lithium ion, on testing with my noob skills, managed to find 2 dead mosfets on the controller, next step was a phone call to petrolscooter, who informed me they were fresh out of 48 volt boxes, a trawl on ebay came across a 3 speed elifebike.com sold by user pedal made easy, it was duly ordered, http://elifebike.com/peng/iview.asp?KeyID=dtpic-2012-AX-RAUE.7YSWB

now its here, im having great difficulty in finding the proper throttle and speed led switch, can anyone help, my existing throttle wont even connect with it.

Kind Regards from the western Isles

Too much irrelevant information, not enough relevant information. You can connect any throttle to the Elifebike controller. Show us the wires on your throttle, and we'll explain how to connect it. What's a "speed led switch". I've fitted hundreds of controllers including those from Elifebike, but I've never heard of one of those.

connected the sm wires and turned on, motor moved forward, but very stuttery and then stops after 2 seconds, your lucky if its turning a centimetre and then stopping, iv tried disconnecting the sm wires as per instructions, and then using the throttle, but no joy.

any ideas folks ?, could my motor be blown or a sensor not working right ?

The stuttering sounds like it could be a bad hall sensor in the motor. I would try testing the hall sensors. Make sure you are getting +5V from the hall sensor plug when testing the red and black wires.

here is a good resource:

I doubt it is a sensorless controller, but you could try disconnecting the hall sensor plug and get the wheel spinning and then try the throttle.

You can't always connect connect color to colour on the phase and hall wires. You have to find the correct combination out of 36 of them. Do not give your bike full throttle until the motor runs smoothly otherwise you'll blow the mosfets in the controller.

Another thing, check that the phase wire bullet connectors are tight and all other motor connectors are sound.
