Kit for a dahonJetstream folding full suspension bike, overall kit was good , the negatives, peddle sensor did not fit but an alternative was sent and to be honest was a better more compact part which I prefer, battery heavy on the bars , slips down and the strap cannot be used due to the stem configuration, a little of inner front forks had to be filed to fit the hub in. Most of these issues due to the quite rare type/model of bike. Brake cables have not been fitted as a little short on space, but has not given me any problems. The pull from the motor is good and flattens the hills easily. Hard to tell how long components will last but all good so far (only4 charges). I would recommend this product/company to everyone. I personally would prefer the battery/controller as a water bottle type to keep the weight lower and away from brakes,gear cables,lights.
