After ordering kit, didn't here anything from Swytch for a long time, company should do regular up dates each month.Been riding now with the Swych kit now for 8 Months now, i have a few issues with the kit which is mentioned further in the review. Fitted kit to a Btwin 900 Tilt folding bike, the lightest bike i could find. After receiving kit, it was easy to instal, the only tricky part was getting sensor in the right place, remedy moving sensor with Sugru Mouldable Glue, sets hard in 24hrs it wont move now. Once that's sorted pop the charged battery on cradle & you are good to go. The only issues i have with the Swytch kit is range they quote 17 miles on the Air Max i am getting around 11 miles , at the lowest settings. Also in future when the battery is in the cradle it is still on, should have a button to switch off, instead of removing the whole battery. If you wanted to order extra Batteries or other accessories you are unable to do that after the order process has been completed. Just be careful when using power settings the higher you go more power you use lowering your range(really fast on 5 ). Overall a good lightweight kit.
