Thanks sjpt. Having motored around a bit this morning I've found the throttle is not completely dysfunctional. It the highest gear settings ie 5 and 6 when pedalling slowly before the motor comes on automatically, turning the throttle will cause the motor to kick in
However in all the other gears the motor comes on automatically way too early ie after a couple of pedal revolutions while the throttle is 'off'. So it's nigh on impossible to get any real exercise pedalling manually as the motor is just to keen to show its stuff. The other issue is this will of course drain the battery much quicker. I guess my question is , is there any way to adjust when the motor assist kicks in on a basic bike like this ?
