I finally had a chance to ride my ebike for a short period of time today. I had to drop my car off at the garage and needed a way to get home. I loaded up the bike into the car and headed to the garage. I rode back home on it in short order!
As for the next upgrade, I picked up a pair of Avid BB7 Disc Brakes from eBay and they should be arriving shortly. I can't wait to mount the rear motor and front wheel with disc brakes. Right now, my V-brakes last only 6 weeks before I need to replace them. With disc brakes, I hope to eliminate this need, at least for a few months instead of a few weeks.
