Yeah, I noticed that too! 👍 Once you get up around 20 MPH and above, the motor is pretty much doing the heavy lifting and pedaling doesn’t add much more speed. 😄 At those higher speeds, I found myself mostly using the throttle anyway. Thanks for pointing that out and for watching! 🙌🚴💨

I weigh 200 lbs 😃 congratulations on your new bike. The rear suspension I had to play around with because it would rebound hard but once I got that the bike ran really smooth.
