Hi everyone. My friend has some kind of Pashley trike which has had an electric assist system added to it. The type with the motor as the hub of the front wheel.
The front axles protude from either side of the hub/motor in the usual way, and bolt into normal dropouts.
The problem is that, no matter how tightly the nuts are done up, apparently the front wheel comes right out of the dropouts after just a matter of a few 100m, or a mile at most. As in, right out, and it lies twitching on the road.
I have attached the best pictures I could get... which aren't very good... but I wonder if you have any ideas? Apparently the trike has been taken to a bike shop and they tightened it on really well... but it still comes off.
