I Have bought and fitted two kits 1st was a early incarnation on my wifes bike no issues 2nd was the newer version on my hybrid bike. Constant problems from delivery nearly a year late, hub motor issue after 1.5 years which I had to fund the replacement as it was out of warranty, latest issue is the handle bar mounted control panel has stopped working. Customer service/ after sales care is non existent don't hold your breath waiting for a reply from 'support' how they can call it support with a straight face is beyond me. In short if you are thinking of buying DO NOT. I put the above review on Trust pilot and Swytch quickly responded saying they would contact privately. Swytch did contact me privately asking for a video of the installed kit then NOTHING in terms of response (NO SUPRISE) I have chased four times via email ( the only way to contact, Swytch do not allow phone calls) and no response at all. So they may commented publicly that they are helping me, do not be fooled, they are not. As I said below if you are thinking of buying a Swytch kit whatever you do please DO NOT.
