Hello, I decided to see if my local (non-electric) cycle shop would be able to do my repair. In fact when they said they would I decided to take the chance to have new , fatter tyres fitted. The shop couldn't have been more helpful, they hadn't dealt with an electric bike before but figured out how to disconnect the motor-and also sorted the front wheel, which they noticed Halfords had put back on back to front ! I took the bike out today as soon as I got it back , the only problem is that while pedelec is working fine the throttle isn't working atall. It may just be something that hasn't been re-connected but I'm wondering if something could have been damaged when Halford's were trying to get the back wheel off before deciding they couldn't do it, as the local shop found connections hanging loose,even though the repair wasn't done.Any advice would be appreciated, thanks:)

The throttle connections are only between the throttle itself and the controller, which I guess on your model is beneath the battery. There are no connections from the throttle direct to the motor and the motor connections to the controller could not cause this fault.

 

Therefore first check out the wiring from the throttle to the controller, making sure nothing is unplugged or disconnected en-route.

Does the throttle work briefly when the bike is stationary? If so they may have connected up an unwanted lead which disables throttle only.

Hi Mussels, no its completely dead, absolutely nothing happens when I twist the throttle:mad:(

Hi there,

 

Switch off the battery or remove it from the bike.

 

Have a gentle probe around the controller housing underneath the battery - you'll should see a couple of purple wires, if they are connected - disconnect them.

 

If you can't locate the purple wires easily - using an allen key remove the 3 bolts securing the controller housing plate to the l/h side of the bike (non crank side) - this will give you access to the controller. It's a silver box about the size of a cigarette packet with various cables spewing from it - don't be put off but have a gentle probe and a good look for those purple cables. Disconnect them if they are connected together. Fix the plate back on to the controller housing.

 

If that doesn't resolve the problem please contact Wisper Support:

All the best

Thanks Steve, I'll let you know how I get on:)
