AOSTIRMOTOR S07-B/E/F 750W FAT TIRE ELECTRIC MOUNTAIN BIKES

AOSTIRMOTOR S07-B/E/F DESCRIPTION

Are you looking for a powerful fat tire electric mountain bike to take on your next off-road adventure? Well, take a look at the bestselling S07s from Aostirmotor Ebikes. When I first test rode this beast, I was very impressed. From its lightweight 6061 Aluminum Alloy frame to its high-torque motor, the performance was on par with ebikes twice its price. 

Aostirmotor Ebikes is known for producing a range of high-quality ebikes at budget prices, and the S07s are no exception. The only difference between these models is the color. They come with 7-speed Shimano Sunrace gears which shifted smoothly throughout their range and gave me a nice workout before I turned on the electronics. 

They say the 48V S07s can reach a top assist speed of 28 mph, and they weren't kidding. This ebike goes fast. I found the 5-level Pedal Assist System (PAS) to be very responsive, sensing the changes in the amount of torque I was applying to the pedals. The half-twist throttle had an easy-grip narrow profile and was quite springy and responsive to minor adjustments. The motor is paired with a 13Ah lithium-ion battery for an extended range of travel per charge.
