With our I-PAS technology (Self-charging), this battery will help you to reach 50-80miles+ range per charge. When fully charged, the battery lights are 3 green 1 red.

350W HIGH SPEED BRUSHLESS GEAR MOTOR

As the most important part of the IPAS system, we changed the internal structure of the motor so that it can generate electricity when the rider goes downhill or gliding, providing additional energy to the battery. Of course, it also has the function of a general motor. With this 350W high speed brushless gear motor, you can reach to the top speed in 15s. It will provide you with 45Nm of torque to help you conquer most of the rugged terrain. And this motor is very friendly to those beginners who just start riding with Ebike. 

160MM MECHANICAL DISC BRAKES

With these front and rear mechanical 160mm disc brakers, you can stop the bike in a more effective way, even in loose terrain. Stop faster when it counts the most. The mechanical disc brakers are currently the more popular type of disc brake for the average mountain biker. One of the main perks of the mechanical disc brake is that the cables are far easier to install and they work more efficiently.

SHIMANO 7 SPEED GEAR SHIFT SYSTEM

A 7-speed bike is a great bike for a person who rides on tricky terrain. It’s main purpose is to let the bike adapt to rough conditions and accommodate inclines, bumps and other difficulties. On a 7-speed bike, the lower gears make it easier to pedal and the higher gears allow for better movement going downhill. Compared to a 3-speed bike, a 7-speed is preferable for a rider who travels on varying terrain.

With this Shimano 7-Speed Classic Transmission System, you can easily increases hill-climbing power, further range variation, and greater terrain adaptability. You can adjust suitable speed to complete your journey.

Shimano MF-TZ500 7speed 14-28 TOOTH FREEWHEEL

The 7 speed, 14-28 free wheel means you can shift to a larger cog for uphill riding, downshift to a smaller cog at high speeds. This greatly increases the comfortable performance of the bike on hilly terrain. Multiple geared bikes also require replacement gears less often, because abrasion is distributed among multiple chainrings rather than a single chainring.
