The Aostirmotor S18 is a fun and affordable electric mountain bike. It features a powerful 750W rear hub motor, paired with a mid-range 48V/15Ah removable battery with Samsung cells.
This powerhouse is controlled by the 5-level Pedal Assist System (PAS) and a right-side half-twist throttle, giving you great control over your riding experience.
The full-suspension frame absorbs the impact from uneven surfaces, especially if you go off-road on heavily rutted trails. During my test ride, I was very impressed with the performance of the suspension system, as well as the bicycle handling and electronics.
If you are looking for a high-performance fat tire, full-suspension electric mountain bike for under two grand, the S18 should definitely be on your shortlist.

I love it. The 750-watt motor has plenty of power. If like me you live in a hilly area, this bike is a very good choice. You'll soon get the hang of which gears to choose under various hilly conditions for easy enjoyable riding. I am impressed by the construction of the bike and its performance has been exceptional.
I needed a powerful full-suspension mountain bike for myself. My husband got the S18-1500, but honestly this 750 is perfect for my lighter frame. It's very responsive and I like the unique frame design. Great customer service as well, so thanks for that.
I am immensely enjoying my new ebike and the freedom it offers. This bike has lots of power, if you need it, and solid construction. I am completely satisfied with the value for the dollar and I'm enjoying getting to experience various travel goals.
