I like the bike, but there is one major issue preventing me from giving it five stars. The bike has the cadence option installed. Power to the motor is dependent on bike speed when pedeling. The faster the bike goes, the more power to the motor. No matter which pedal assist, there is no power to the motor when you begin pedaling from a stop. It is difficult to start the bike moving and little power goes to the motor until the bike reaches about 15 kmh or 10 mph. This issue can case the bike to stall and fall over on a trail when you need to go slow before a sharp turn, then up a hill. This issue can be somewhat mitigated using the throttle. Significantly more power is needed to the motor to assist in moving the bike from a start.
