I owned Swytch kit for just over 2 years now. My honest advise is do not buy Swytch. Go elsewhere. My purchase (The Brompton Conversion Kit) developed problems after 4 months of use. It took 6 months to address those problems and I did not get any warranty extension, despite not being able to use the product for more than half of the warranty time. 4 months after the repair I got the same issue. Swytch told me that my Warranty has expired and refused to repair under Warranty. Long wait again and only after legal actions taken I received battery replacement, which failed after 5 months!!! Now I am waiting for over two months to receive the controller, which was under 6 months extended warranty. APPALLING!!! Why 2 stars – well, if the kit works it is great to ride. However, these kits are made in China and there is probably no quality control check at all. So, if you are lucky and it works, then it is great addition to your bike at reasonable cost. Otherwise, waste of money and time. I think SwytchBike also suffers from suppliers side which is down to either Brexit issues or poor choice of supplier (probably in attempt to cut the costs). You can see that from number of complaints about late deliveries (and I am not saying late by few days, or even weeks… it is months). It looks SwytchBike do not hold much (if any) spare parts, so if you (like myself) have issue with one component you are stuck for months with unusable kit. I have been to their office/shop – it is a small warehouse, barely 50 sq meters. Customer service would definitely be 1 star, or even zero star. SwytchBike actually lies to us – on the website they state ReviewsIO as 4.8 stars. It is actually 2.9 stars, and going down. TrustPilot is 3.2 and going down. From reviews you will see that SwytchBike lie about delivery and repairs time. They lied to me so many times. Judging by my experience, my advice would be to stay clear from Swytch and look elsewhere for electric bike solution. I am now exploring my legal rights and try to get some justice (an repair) that way. I do not know how Reviews.io works, but I would be happy to be contacted and exchange experiences and give more advises.
