Overall, I am really pleased with my Brompton Pro Swytch kit. Like many there was a slight delay in delivery due to the surge in demand for ebikes but this wasn't an issue for me as I bought the kite to convert my work commute bike and due to the ongoing Covid situation, I am still not back in the office. The Brompton Pro kit initially suffered from some vibration issues, however they have managed to fix this with a software update to the controller. Drawing a line on all of that I now have a Brompton kit which I love. It allows me to do 20mile rides without turning up looking all hot a sweaty. It has also opened up certain routes which were to advanced/tough for me, i.e. really steep hills no longer a problem. Overall I would recommend. The initial supply and performance issues were all resolved and over time I am sure the company will iron out things like this. I am left with a product I really enjoy riding.
