2025 Aostirmotor S18-1500W 48V 7 Speed Full Suspension Fat Tire Electric Mountain Bike

The Aostirmotor S18-1500W 48V 7 Speed Full Suspension Fat Tire Electric Mountain Bike is an off-road monster. 

You can ride this electric bicycle on some rough terrain and it can conquer them all with sustained power output. 

The S18-1500W all-terrain bike has a full suspension frame, which along with the robust fat tires, will absorb a lot of bumps on a rugged trail.

The Aostirmotor S18 1500W battery is integrated into the curved lightweight 6061 aluminum alloy frame, and provides 48V of power and a long-range 15 amp hour capacity.  The battery can be easily removed from the bike for remote charging.

You can turn on the 5-level pedal assist system (PAS), and monitor all essential readouts on the display.  If you prefer to ride without the need for pedaling, you can simply give the right side throttle a twist, and off you go.
