CLASS 3 INTRO
A Class 3 e-bike has the following characteristics:
Electric Assist: Class 3 e-bikes are equipped with an electric motor that provides assistance while pedaling. This assistance can be controlled by the rider and is usually limited to a certain speed.
Speed Limit: In the United States, Class 3 e-bikes are typically limited to a top speed of 28mph.
Pedal Activiation: The electric motor on a Class 3 e-bike is activated by pedaling, meaning it provides assistance when the rider is actively pedaling, and it ceases to provide assistance when the rider stops pedaling or reaches the maximum speed.
Please note that regulations and classifications for e-bikes may vary by country, state, or region, and they may change over time. It’s essential to check your local regulations and laws to ensure compliance when using an e-bike on any trail, or dirt road.
AUTO SHIFT: AUTO SHIFT is an automatic shifting technology that monitors your pedaling dynamics to keep you in the right gear and focused on what matters in every moment. Multiple system sensors continually measure your cadence, torque, and speed to automatically move you into the optimal
gear without requiring you to shift manually. As your speed and cadence slow and torque increases, the system selects an easier gear. When you start pedaling and speed up, the system shifts to a higher gear for you, so you can always be in the right gear at the right time. To toggle AUTO SHIFT functions use the smaller button below the power button.
A1 - 90 RPM, A2 - 70 RPM, Manual.
Free shift: While coasting, the drive unit uses just enough power to rotate the chainring and cassette to smoothly complete shifts and does not affect the acceleration of the e-bike. You do not need to be pedaling the bike for it to shift.
