Having fitted the Swytch kit 3 months ago I can highly recommend it. It has encouraged me to use my bike when I wouldn't have considered it previously. The larger battery seems to to be ideal for my use. The installation was easy having watched a couple of YouTube videos showing the process. The videos highlight some of the optional installation items that are in the manual, but as I usually find watching is easier than reading :) Build quality of the components seems good and the connectors seal well against our lovely weather. Overall, I am very pleased with my upgraded bike, I just need to order another one so my wife doesn't get left behind when out riding.
