4. Operating Your Electric Bike

The JANSNO X70 offers versatile riding modes and powerful performance for various terrains.

4.1 Riding Modes

Your electric bike supports both pedelec (pedal-assist) and throttle modes. In pedelec mode, the motor provides assistance as you pedal, extending your range and reducing effort. In throttle mode, the bike can be propelled solely by the motor without pedaling.

4.2 Power and Range

Equipped with a 750W high-speed brushless motor, the X70 can reach a top speed of 30 mph/h. The dual 48V/14/20Ah lithium batteries provide an extra-long cruising range of up to 120 miles per full charge, depending on riding conditions and assist level. The batteries are removable for convenient recharging at home or office.

4.4 Terrain Adaptability

The 20" x 4.0 snow tires are enhanced for anti-skidding and wear-resistance, making the bike adaptable to complex topographies including snow, sand, and gravel roads. The high-carbon steel frame is designed to easily climb inclines up to 30 degrees.
