Big problems, with the big bikes.
Bike 1 has a wobbly front wheel; a replacement is on a slow boat from China.
Now bike 2 has failed! I was in the middle of nowhere (of course) when the motor decided to stop working. Fortunately, that had happened after the worst of the terrain, so I had a bit of downhill, and then a long bike ride on tarmac.
When I got home, I investigated. The motor runs, but only in fits. If I run the wheel backwards for a few inches, then about a third of the time the motor will run for several seconds before cutting out again. I've changed the battery, the controller and the throttle, and I'm baffled. If anyone has any suggestions, I'm listening.
Fortunately, I've recently sorted out my small bike, the 20 inch wheel folder. The drawback of this bike is A) no back rack, and so only limited capacity to carry things, and B) only six gears, whereas the big bikes have 21. In addition, the smaller wheel is at a bit of a disadvantage over very rough ground.
Still, beggars can't be choosers - I'll be going out on that bike until I sort out one of the bigger bikes. Hurry up, slow boat!
