It is cheap compared to buying a purpose made electric bike and far less wasteful, and has really improved my ability to tackle the steep Cornish hills, having moved to Cornwall last year with Long Covid symptoms I did not enough energy to get up the hills! I love the cycling experience of using my Swytch bike, and only turn it on for going up steep hills, or if I have got a heavy load of shopping to bring home. The battery life is not very long if I put it on the highest setting of 5, but as my personal fitness has improved, I can go up steep hills on settings 3 or 4. I bought an extra battery as I had heard that this was the case, and glad that I did so. IT NOT EASY TO FIT - it did not live up the advertising hype, I had to take it to the local bike shop twice. It is really fiddly and the email support to my queries was not much use as it kept on referring me to pages in the manual rather than actually understanding my question and attempting to answer it. However persistence and Youtube videos made by previous owners enabled me to succeed. Because the wheel with sensors attached to the pedal arm is not encased after going through muddy puddles or mud (I have a mountain bike), the power input can become erratic (a jerky on/off motion) or cease to function. This means taking plenty of tissues and/or a rag with me to clean it thoroughly and dry it off. The winter months and a rural location means muddy flooded roads are unavoidable. I bought a throttle as an extra item and am very pleased with it: it enables me to get moving if I stop on a steep hill or need to start from stationary at the bottom of a hill and/or have a lot of weight on the back. It uses a huge amount of battery power so I only use it sparingly. The control display is not easy to use and I often have to stop pedalling to change power settings, and this has not really improved with experience. Still need to discover how change from kms to mph. It took 4 months to be delivered and that only happened after paying for the whole thing up front. That was not counting the several weeks of being on the waiting list before I could give my detailed order and pay in advance. The quality of the components appears to be excellent and one of the reason for choosing this rather than cheaper (and non-UK) manufacturers was the feedback from three bike shops whom I consulted. They all said the same thing: Swytch bikes do not often come in for repairs, parts ordering is quick and reliable and they are easy to work on and are made very well; they all said the cheaper models (mostly from China) were often in for repair, with parts often unavailable and very expensive, and difficult to work on, one shop told me that they would have to send a technician to China to receive the training required, which for a small independent business is totally unrealistic and expensive. It is good to be able to buy a good product from an innovative British company.
