AOSTIRMOTOR S18-1500W DESCRIPTION
Do you crave speed and power? Do you want a fat tire electric mountain bike that can tackle the steepest and roughest terrain out there? Well, get ready for an ebike riding experience like no other.
The Aostirmotor S18-1500W is an off-road beast. I've tested a lot of powerful fat tire electric mountain bikes, and the S18-1500W really blew me away. I rode this ebike on some of the gnarliest single track trails I could find, and I was really impressed with the sustained power output.
Aostirmotor 1500W is not just about power. It offers a full suspension frame, which along with the fat tires, will absorb a lot of the bumps you might encounter on a rugged trail.
The Aostirmotor S18 1500W battery is integrated into the curved 6061 aluminum alloy frame, and offers 48V of power and a long-range 15 amp hour capacity. Range will vary by several factors, including total payload, surface conditions, and riding style, but on average you should expect about 36 miles of range per charge. The battery can be removed from the bike for remote charging.
Using the electronics on the Aostirmotor S18-1500W fat tire electric mountain bike was intuitive and easy to learn. You can turn on the 5-level pedal assist system (PAS), and monitor all essential readouts on the display. And if you prefer to ride without the need for pedaling, just give the right-side throttle a twist, and you're off!
