They quoted for $1000 USD + $85 for shipping, and I also have to pay the wire fee, because they don't accept other forms of payment. I made a few videos to give you some ideas. One is bike pickup speed without me peddling. The other few, same setup, but with my assistant initially to get the bike up to speed. Another video shows how the motor reacts free rolling the tire and when the brake is applied.

The rear wheel on the brompton is small enough so you can actually get the bike rolling without pedaling. But it's not enough torque (could be traction) to start quickly. So I find myself shifting to lower gear at traffic stop, so I can get start with my own power and get it going quicker. That said, the motor is completely fine getting me up to speed, it just starts off a bit slow. As the rolling reistance gets lower, it picks up speed very quickly. went through a couple of puddles, but not in the rain yet. Can't comment on this. Not enough time on the bike yet. The noise is there. Much quiter than I expected. Outdoor, it's drown out by the wind noice quickly. No it does not have return spring. In fact you really have to learn how to use it. When you are about to pull a full stop, you MUST remember to turn the throttle off. It's a safty factor I think. I noted this and suggested they should add a sensor at the brake level to cut off the power when the brake is pulled in. The motor will jerk and rattle when the tire is not moving. I've not dared to try test the limit of that by holding the wheel shut and run the motor. I have a 6 speed reduced gear. I don't really use the hub gears (3) any more. Just toggling the other lever from high to low at stops is enough. Once the bike is at speed, the other gears are not really useful. I live in a really flat area, I only had to 'climb' a bridge over pass. Does not feel like the motor was struggling at all, partly because I had lots of momentum... Can tell If you use the bike for communting only, 3 gears is probably enough. But I need my bike for touring too, and I plan on using it without the motor as well.

I've been in contact with them since Feb. And recently installed mine. Since this is one of the two post that comes up on google search. I would like to contribute some information, as it was very hard for me to get any details on the kit during my own research. I received the unit with no instruction (they were still developing it, and I had that understanding before my purchase). It's pretty easy to install. So far it's been great. Only beef I had is they did not supply and additional cable to relocated the battery. I was quoted an additional $40 to get the cable (w/ shipping cost). A brake switch to cut-off the power would be nice as well. If you have the pedal assist (euro model) it won't be a problem. I have the Korean, US version which does not have the hall effect sensor for pedal assist. https://www.youtube.com/watch?v=jeMowqxl6n0
