Did a Brompton conversion on my wife’s bike back in March 2021. The conversion was pretty straightforward but it was comforting to have a video check done on completion. There were a couple of build issues but their customer support was excellent and replacement parts arrived in a few days. On the road the bike was transformed and my wife loves it. After a few rides it developed a fault where there was a power judder from the front wheel. Again customer support was excellent they said they were aware of the problem and were developing a software modification. After about a month ( delay to to post Covid transport issues) I received a replacement controller with full fitting instructions. This fixed the issue and since then the system has worked well. We have the old heavy battery fitted on the handlebars and this is not an elegant or very stable solution. Good to see they have now developed a small lightweight battery but unfortunately it’s too expensive for it to be worthwhile for our bike. The range with the old battery is around 20 miles which is all we need but might not suit everybody. All in all it’s been a successful project and the support I have received from Swytch more than made up for the small problems along the way. I have not commented on delivery below as being just post Covid there were all sorts of transport problems but again we were kept well informed on developments.
