I took my ebike and trailer across the weigh scales on wednesday. The combined weight was 175 kilograms. I had to peddle assist up a moderate hill to get there. My speed was probably a little less than 20 km up the hill but I made it.
Regarding pedal assist, I can't pedal fast enough to reach 45 km/h with my current gear ratio although I do have a larger front sprocket that I can install someday when I find the time to make an adapter plate.
By the way I find 30 km/h to be pretty scary at times, and is considerably faster than virtually every other bike on the road.
One bicyclist was as fast as I was but I think he was a competitor in a local bicycle hill climb contest because I haven't seen him since.
