Aostirmotor S07-2 | S07-2-C Description

The S07-2 and the S07-2-C are pretty much the same, with the only differences being the frame colors and the S07-2-C includes fenders whereas the S07-2 does not.

When I first rode the S07-2 | S07-2-C from Aostirmotor Ebikes, I was blown away. I've ridden a lot of ebikes in my time, but this fat tire electric mountain bike went straight to the top of my list. Honestly, I don't think there is another 750W fat tire electric mountain bike on the market today for just over a grand. 

Some people think ebikes are cheating, but this couldn't be further from the truth. For the first hour of my ride, I never even turned on the electronics. I relied solely on the 7-speed Shimano Sunrace gears, which shift smoothly and cover a wide speed range.

When we started to encounter some steeper hills, I gave the 5-level pedal assist system (PAS) a try, and I was impressed by its performance. It was very responsive and really gave me a boost while I pedaled. On the way home, I was pretty exhausted, so I used the twist throttle to propel the bike, and I was equally impressed with the way it performed. 

Here is a video review of a customer's first look and ride of his Aostirmotor S07.
