I ordered the Brompton kit in May this year, this to fit on my Dahon Boardwalk Folding Bike and despite the various problems caused by Covid 19 the kit arrived on the 9th October, Fitting did not take long and apart from fitting the front wheel the wrong way round initially, which was soon rectified, ( I had put the bike upside down to facilitate installation. ) Overall it took me about 2 hours to get everything sorted and ready for the test photos and video for the warranty. Once completed I did a short test ride to check everything was working correctly and the put the battery onto charge again. I have subsequently carried several minor modifications such as repositioning the pedal sensor, wrapping and rerouting cables. My longest ride to date is only just over 10 miles and I returned with 2 bars left on my Eco battery, I expect I'll improve my mileage and battery life as I get fitter. As a septuagenarian, I doubt whether I'll achieve the fitness level of my youth but the Swytch Kit has got me out on my bike again and enjoying the ride. Overall I'm very pleased with the kit, but in hindsight, I think I should have bought the Pro Battery
