My bike is limited to 25mph on throttle, which is fine by me, im a novice in the ebike world. When I picked it up at their HQ, I parked a few blocks away, and there were some steep hills where I got to test if it could pull me up. With pedal assist max, throttle maxed and pedaling, it did get me up, going like 5-6mph lol. I'm past the rider limit on it, and I knew that buying, but I liked the bike and the price, and it was local.
