I live in hilly Hampstead in North London and find when I leave my house on my Brompton I always turn right to avoid cycling up the hills. I’m also 59 years old and my knees aren’t what they used to be. Since receiving and fitting my Swytchbike kit (fitting took just 3 hours and was well described in the accompanying manual) not only am I able to turn left and discover the joys of hilly north London, the assistance means I don’t have any pain in my knees when I cycle. Considering the price and quality of the Swytchbike kit compared to other options, it is in my view by far the best way to enjoy electric cycling.
