1500 miles and the batteries are still holding up well. 160 cycles. Hottest commute temperatures 97 coldest 55 in the last 500 miles. The only problem so far has been a catastrophic failure of the bike rack and the quick wear on the 23c rear tire. The rack was a pretty cheap and probably only designed to hold about 25 pounds and since switching frames I'm running a 28C on the back now and the ride quality is so much better. Fenders are next but will have to wait a little since I spent that money on a new rack.
