Delivery was stressful as the kit arrived around 3 months later than promised and there was essentially no communication from customer service regarding the delay. Also the kit arrived with the wrong wheel size. Swytch did seen out a replacement wheel promptly which was appreciated. The product has worked great since it arrived. Installation was fairly easy. It would be nice if there was a way to adjust the acceleration as a function of pedal speed. It seems a little aggressive accelerating to max speed for how I like to ride even on the lowest power setting.
