This is a great conversion kit, simple to fit and a hoot to ride. My car hardly gets used any more! I fitted the kit to my commuter bike which makes carting laptop, clothes, lock and lunch to and from work so much easier! The other big plus is I can ride the 10 miles to the office (including 2 long hills) and not arrive in a sweaty mess in need of a shower. My only criticism is that, with the battery bag attached, there isn't anywhere to mount a front light. Swytch obviously thought of this and built one into the bag itself but if you need something more powerful then you're going to need to get a bit creative.
