Bought a kit in July 2021, had to file the forks of my bike to make it fit! No mention of this in any instructions or installation videos. Soon found out the range was nowhere near that suggested distance even on the lowest power setting. The kit has had very low use but the battery has always been maintained and stored within their reconditions and still hold the power well Soon I had an issue with a grinding noise from the front wheel and after many messages and videos to Swytch it was eventually advised to disconnect the Hall sensor. When I queried this I was told it was an acceptable cure! Surely they fit this sensor for a reason? Since then I have developed an issue with the kit cutting out after 3 miles of riding even though the battery is showing 3-4 bars of power which I can’t help think is linked to the original grinding issue. Back to the constant messages to and from plus another accompanying video was requested and eventually it was diagnosed as the controller was faulty. They supplied one for £60 inc P&P which I was dismayed to see was second hand when it arrived. Once again, no response when I pointed this out. Fitted but didn’t cure the issue. Back to the now becoming regular messages back and forth plus more videos to be told I needed to upgrade the battery pack at a cost of £200 + £30 P&P with no offer to refund the £60 I had already wasted on the controller I didn’t need. I asked where I stood if the battery kit didn’t resolve the issue and guess what, I didn’t get a reply!! Against my better judgment I decided eventually to go for a full, new Go kit as it was the easiest way to resolve the issue myself as their support was 10 parts of useless. Their ordering process is as quirky as their customer service. You have to select the kit, pay a deposit then you put in the specifics like wheel size and any accessories you may require. Once I got to this stage I found there was only a choice of a silver wheel which to my mind would look grossly out of place against a black rear wheel. Once again, back on the emails only to be advised if I wanted a black wheel I would need to upgrade to the much more expensive Air bundle. No offer to supply me with a black wheel to go some way to make up for all the issues I have experienced! To be honest at this point I saw red and told them politely what I thought of the service I had received and cancelled my order. No response, not even an apology or acknowledgment of my email, just a standard email confirming the cancellation. I am left feeling totally let down and way out of pocket having bought inferior goods. This company is only interested in selling new kit and no real interest in present owners or keeping them happy which in my mind is very short sighted as they have now lost a sale to me and everyone I know who had showed an interest in an E-kit bike for commuting plus any other website I can share a review of my experience. Totally disgraceful behaviour, I could not recommend them or their products and definitely would never buy from them again. I have now purchased an E-bike and what a difference, much smoother and responsive plus no noise and a much better range. Sure if cost more than the Swytch kit but if you add together the money I had already wasted with what I needed to spend to get it working again the e bike is actually cheaper.
