I bought a BionX PL-350 kit in 2011. So I've used it for three seasons. In that time, I've had the following problems:
- Wobbly Cassette - this problem has never been addressed. I've been told that it's normal to have some wobble, but it has been significant enough to cause the bike to shift poorly and to cause premature wear of the cogs and the chain.
- System Failure - I had to have a circuit board in the unit replaced in 2013
- Poor Freewheeling - this year, I've noticed a lot more drag. When turned with some force, I get less than one full revolution from the wheel. I tried to have this fixed, but the dealer told me that this is normal. However, I know that the bike felt more like a bike in previous seasons. Now it feels like a bike riding over jello.
