Excellent customer support and quality in product line, a snap to install. The addition to our 7 year old Bromptons has been great we ordered two units for our bikes which came to us during the height of Covid. Our first major ride was up a 4.5 km hill climb at 32 degrees followed by a second 8.5 km hill climb at 20 degrees. Both rides used less that one power bar, there are 5! We live at sea level surrounded by hills and mountains. Our motors worked flawlessly and climbed the hills as if we were on the flat. We still like to work our bikes for the exercise and have the option to turn the motors off with little or no resistance to our normal ride, but when it comes to hills, the Swytch Motors simply flattened them out! One of our units had a bit of an hiccup however the Swytch services reps (Laticia, Jonathan, Liam, and Martin) were excellent sending us advice and replacement parts in a timely manner. We are nearly 8000K away from London and yet we are an email away from support. We are looking forward to an updated battery pack for one of the units which I am sure will be arriving shortly and many more adventures on our Bromptons, thank you Brompton for a great bike and especially thank you SWYTCH for opening up a whole new world of fun!
