I have been riding my new Swytch eBike for two weeks now and it's great. The battery lasts longer than expected but I guess it depends on rider weight, terrain and how much power assistance you use. For me (I'm not skinny or super fit), I can ride for two hours and still have some power left. (I'm using the cheaper Eco Kit) I often ride with my 17-year-old son on his racing bike (who is skinny and fit) and now I can keep up with him without breaking into s sweat! The bike feels just as good to ride as before - only a lot lot easier! But should I ever run out of power, it's no problem to ride home using just muscle power. Fitting was straightforward - change the wheel, fit the pedal sensor and the battery to the handlebar, and connect a few cables. Everything I needed was included in the kit. And the support team is very responsive should you have any questions. I only had to contact them about the warranty survey which involves submitting pictures of your kit so they can confirm it's fitted correctly. So if you want to give your bicycle a new lease of life Swytch is a great investment. I might have cycled twice a month before but now I'm looking forward to my ride every other day.
