I bought this bike because it has a backseat And was excited to try it out. After setting it up, I noticed the throttle was not working. I contacted Support and was told the throttle does not work unless pedal assist is turned on. This would be fine if pedal assist level one was mellow, but it's not in the least bit. Unless you plan on always having pedal assist on and are OK with getting your neck jerked back when you takeoff. I would think twice about this bike.
No where in the description does it state that the throttle doesn't work unless you have a pedal assist enabled.
