Don't know if this is the best place to post regarding an electric Brompton, but the Brompton part of the machine seems best answered here. So, I'm curious if anyone has experience with the Tongxin motor kit (http://www.freedomebikes.com/Brompto...onversion.html or http://www.electricwheel.co.uk/produ...-brompton.html) versus the kit at NYCE Wheels (http://www.nycewheels.com/brompton-e...e-motor.html)?

Thanks
