I could cry! I haven't yet had one decent ride on this bike . I purchased the pro, hoping to get a decent 35 mile ride on one charge. I have had a sprodiac 4 mile ride before the power pack cuts out. And then it is hit and miss to whether it works! First they thought it was the bracket which I changed, and it made absolutely no difference. I contacted them to let them know and nothing was done. Extremely disappointed I put the bike aside for the winter. I desperately wanted to see someone about it and took it to Halfords but they could not help. I then contacted Swytch again to tell them about my dissatisfaction and a really lovely chap brought my hopes up by saying it was the controller that was faulty. Next day delivery I received the part and was so hopefully about finally taking my bike out on a decent bike ride without any anxiety, as my bike is now incredibly heavy since the conversion and I am surrounded by hills were I live, so literally it kills my back which is the reason I decided to purchase the Swytch in the first place! I followed the instructions from a you tube video to fit the controller, and joyously went on a bike ride. Initially it worked, but after 2miles I stopped at a friend's house for approximately 30, turned the power pack off and put it in my rucksack. Unfortunately, when I went to start my epic adventure the bike yet again failed me ! Thats why I could cry, as I have all these high hopes that just since Ive had this bicycle keep getting crushed! I desperately wanted and have continuously asked whether I could see someone in London and I need reassurance and I've never really had reassurance, remote support; but that's not the same as reassurance that the product is fully operational. I understood this at the beginning as being due to Covid, but so long afterwards, it's just frustrating! I converted this on my own in Lockdown and initially found the pedal sensors difficult to position. I've managed this now but now it has stopped powering. All I ask is for someone to get it to work for me and considering it's never worked only in occasional fits but more trouble than it's worth with its unpredictable and frustrating and a standing joke with my colleagues at work & friends! It's not fit for purpose unfortunately. It has now stopped powering altogether now. I'm so disappointed, it has not been plain sailing at all.
