I was looking for a cheaper alternative to a ‘full’ electric bike. Swytch looked perfect as it is not too hilly around us. I swapped the wheel and attached everything in about 2 hours I was amazed when I tried the bike. I’d never ridden an electric bike before and it made such a HUGE difference Ours is the older, bulkier battery. The new one looks much smaller, lighter and better There is nothing bad to say about the Swytch .. the only reason for 4 stars not 5 is that other ‘purpose made’ electric bikes have become so much cheaper that if starting again i would go through all the options again
