Have you broken a BionX rear axle?
I broke my second axle a few weeks back and was wondering if it's something I'm doing or whether other folks manage to break them? I commute around 3000 miles/year on NYC streets and some are a bit crappy. Still, I commuted using fairly crappy hybrids for 10 years and 30,000+ miles before getting an ebike and never managed to break an axle.
When you break that axle, it means the motor is effectively dead because it's integrated with the axle. BionX does not seem to have a way to replace the axle so the cost is another wheel, around $800.
