I like my Swytch bike a lot now that I have it installed, the way it handles hills and inclines is all I hoped for. The installation is a little tricky, I had to take it to a bike shop to swap the tire onto the new wheel and getting the sensor placed and the spacers figured out for the handlebar was no easy task but I managed. Your website leaves much to be desired, it's not user friendly at all, I'm looking to make a simple purchase of a spare battery and have to go through your support portal for assistance. Overall I give the installed kit 5 stars but I'm giving 4 stars in this review because your customer service is lacking
