Aostirmotor S17-1500W Description

I have ridden a lot of electric mountain bikes in the last 5 year, and I must say that I was really impressed with the performance of the S-17-1500W from Aostirmotor Ebikes. 

The 1500W motor is incredibly powerful, and it never lacked the torque or climbing ability when I took it some pretty gnarly off-road trails. Whenever testing a new ebike, the first thing I do is ride it like a conventional bike, using only the mechanical drive train. In this case, the 7-speed Shimano Sunrace gears were super impressive, with a smooth transition between gears, and an excellent gearing range.

But the S17-1500W was even more impressive when using the 5-level Pedal Assist System (PAS) and the right-side half-twist throttle. The speed sensor was very responsive, sensing the smallest changes in the amount of torque I applied to the pedals. 

Have a look at the performance of this powerful Aostirmotor S17-1500W ebike as it's being ridden on various terrains.
