Bought yesterday (rear inner tube had a small puncture on delivery but replaced by the shop) Just done a 35 mile ride (inc 1300ft climb). Really pleased, comfy, gears good, brakes not as strong as hydraulics but less to go wrong, assist levels good. 1-3 is all I used. I prefer this over the Mahle system, didnt like the position of assist button and cant remove battery. Also Fazua interesting concept but I feel safer with tried and tested Bafung kit. Still had over 50% battery left at end of ride.
