Received my Switch kit to fit onto a Brompton. The installation manual was a little confusing. Differences between instructions in the hard copy manual and instructions on their website. You need to be extremely careful in how you run the cables to ensure your bike will fold up after installation (don't cable tye all the Brompton brake cables etc together or it won't fold). Once installed the bike did ride quite well. I tested it on the flat, and also on a hill. It coped with both. It can be a little jerky, accelerating then decelerating, but I'm sure I'll get used to that, and perhaps resolve this with better setup. It's 3 months since I received my Bike Kits (I ordered 2 kits), but I am still waiting for a tool kit which was ordered as an accessory. I would have really expected this to have arrived by now, but it hasn't. However Customer Support at Switch assure me it will be delivered eventually.
