Love it, probably bit tricky to fit but my husband did it! Didn’t get the programming right at first and whilst the power came on to begin with it dropped off after a while, my husband sorted this by reading up on it and programmed in a smaller wheel than I have. Now it’s just brilliant, my bike looks like a ‘normal’ bike, battery sits at the front, in the basket, I only switch it on when I need it - hills, strong winds, but it makes me laugh with the joy of it and puts a smile on anyone’s face who tries it. Kit did take a bit of time to arrive but that’s fine and the price is well worth it as you don’t have to splash out thousands for a heavy, unattractive (most of them are) purpose built electric bike.
