Good one.
It looks like the electric motor from Sram except that YOU have to provide the engine!
I don't like the device in it's current state but will say it might have a future if they can bring the weight down by 5 pounds (the hub weights 9 lbs). The Sturmey Archer 3 speed hub weights about 2 pounds and that is the standard. However, that might be asking for too much so if they can bring the weight down to 4lbs, it might have a future.
I also don't like the fact that you don't know what gear your're in. Spinning that shifter three complete turns to go through the entire gears would get old real fast. I like the the AW-3 and Sprinter because I always know what gear I'm in and can get there fast without having to constantly make adjustments from a friction shifter.
A 35-37 pound Brompton does not sound very attractive.
