1658 miles on the Haibike 3.0 All MTN, second chain, same tires, it is a climbing monster. Love the reward of the downhills. 500 miles on a Specialized Turbo Levo that my wife owns. Turbo is an unbelievable Treking bike, would take it around the world. Love the Brose motor, but I am happy with my Bosch Performance CX third generation. Pedaling for Life!
