I just took delivery of a new HeyBike Mars (2023) with the new controller
Problem is it is extremely slow. Cannot get it to go more than 15 MPH before it will back off on the electric motor
What I have done already:
1. Verified wheel diameter. It shipped with the wheel diameter set to 23" but the actual diameter is 21". I reset this and now the speedometer and odometer are accurate (checked against a handlebar-mounted Garmin Edge GPS)
2. Checked the max speed setting in the controller. Came set to 60Kph (37MPH) and I cranked it to the max of 63Kph
3. Tried to "fool" it by setting the wheel diameter to 8". This resulted in the speedometer reading much lower but the bike still cut out at 15MPH measured on the GPS
Nothing I can do will get it to go more than 15mph. This is not a weight issue as I have another 500W bicycle that easily does 25Mph (once I reset the speed limit) on level ground. Even going down a slight hill you cannot feel any power assist once it hits 15mph
