Aostirmotor S18 Description
The 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.
