The Aostirmotor S07 750W 48V 7 Speed Fat Tire Electric Bike is a powerful fat tire electric mountain bicycle to take on your next off-road adventure.

This e-bike features a lightweight 6061 Aluminum Alloy frame and a high-torque motor.

Aostirmotor is known for producing a range of high-quality ebikes at affordable prices, and the S07s is no exception.  The only difference between these models is the color.  They come with 7-speed Shimano Sunrace gears which shifts smoothly.

The 5-level Pedal Assist System (PAS) is responsive and senses the changes in the amount of torque that is applied to the pedals.

The half-twist throttle has an easy-grip narrow profile and was quite springy and responsive to minor calibrations.  The motor is paired with a 13Ah lithium-ion battery for an extended range of travel per charge. 

Watch how to install/assemble your Aostirmotor S07 e-bike.



26"x4.0 fat tires provide upgraded grip and traction on rugged roads. Even on the most challenging terrains and weather conditions, these fat tires can guarantee your safety and offer you an easy and smooth riding experience.
