I've owned my Hammer for about 2 years and have about 2400 miles on it. Overall, I'm pretty happy with my purchase. A couple of issues to be aware of:
1) The hydraulic brakes stopped working properly after a few months and I had to get them serviced.
2) The handle bar comes loose after some riding. I've tightened it back up several times, but this keeps happening. I've even taken it to a couple of ebike repair vendors and they can't seem to fix it either. I've come to the conclusion that it's a design defect. As I said, my bike is over two years old, so perhaps they've remedied this is the latest model. I would definitely check with Ecotric on this.
