On my Shimano e8000 on a commencal meta the motor stops at 32 km/hr. But if u have the leg power u can go faster but it is quite tiring. I rode the sea otter e mtb amateur race in Monterey ca. The pros were doing five 2.5 mile laps and the amateurs 3 laps and the proswere started first sonyea now we were both on the course together. Those guys were going way way faster than 32 km/hr because they were pro racers and it seemed to me they had derestricted their bikes which I'm sure wasn't happening. What was happening is that they were amazing riders. Maybe u just are amazingly strong and the other guy wasn't ???
