Had the kit for over a year, found it quite easy to install except for the pedal sensor which i had to modify slightly to suit. My kit is the earlier one which has the bulky battery and i found this has a noticeable effect on the steering as it's a heavy unit. I usually have it on setting 4/5 which suits me as i only cover short journeys. I've not had to use customer service yet as the unit has been reliable so far, on pricing i paid around £550 as i had ordered a black wheel to match my bike, however the wheel had black spokes and silver sidewalls !, overall i am happy with my purchase, the only reservation being the weight of the battery on the handlebars which affects the steering. Swytch should consider another place for the battery mount.
