I am one half of a pair of "twirlies", those of a certain age who are not allowed to catch the bus before a certain time..), we both have an e-bike. Bought nearly two years ago, we have moved a couple of times since then, and have not had time what with all the moving around, to actually ride the bikes. Ours came from Ideal World, Elife Natural, folding with 20 inch wheels. Finally we now find the time, and good enough weather to make use of them. My problem/query is this.. the rear wheel of one of the bikes is locked, will not move, and we can't figure out why. The other bike is fine. We have never ridden them up to now; and when we first unpacked them to check them over, about two years ago, both bikes' wheels turned as they should. Stored in a shed, we kept the batteries out and charged up. Read the manual, which says nothing about a locked wheel..so does anyone have any idea, if I've locked it accidentally, and if so, how does it unlock? The cogs are not turning on the back wheel. The chain appears to be fine. Any ideas or help gratefully received, thank you!
