I have a RadRover 5. I did the Bolton upgrade on the controller, Bafang motor and hydraulic brake calipers. The controller comes with a 35A controller and upgraded color display. The motor, rated at 750w had more torque for hills.

Has anyone seen the new RadRover 6 Plus?  The $2000 bike seems to be configured with similar specs as the Bolton upgrades. The other difference is the integrated fitting battery.
