After a long wait, my Swytch kit arrived and I installed it. The thumb throttle cable was too short for my beach cruiser bike (I managed to buy one before Swytch support finally responded and sent one.) The install went fine except for the initial scare because I did not know the power button had to be held for several seconds to turn it on. I enjoy riding the cruiser with the Swytch pedal assist. The motor makes riding a bike more enjoyable for a person nearing 70. The optional, larger battery seems fine for my riding habits. I live in Mobile, Alabama, United States of America.
