About the ride
SPECTER-S 4.0 — 1000W Mid-Drive Full-Suspension Fat-Tire E-Bike
Built for challenging terrain and all-season exploration, the SPECTER-S 4.0 combines powerful mid-drive performance, long-travel full suspension, and wide fat-tire stability.
The 1000W BAFANG G510 mid-drive motor sends power through the bike’s drivetrain, while the removable 48V 17.5Ah battery provides energy for everyday riding and off-road adventures. A 140mm suspension fork, rear shock, four-piston hydraulic disc brakes, and SRAM NX 11-speed drivetrain help you stay in control across hills, loose surfaces, and uneven trails.
The 1000W BAFANG G510 mid-drive motor delivers power through the drivetrain instead of directly through the wheel. This central motor position helps distribute weight more evenly and allows the motor to take advantage of the bike’s gearing when climbing or adapting to changing terrain.
A 140mm-travel EXPLORER suspension fork at the front and an AO-38RC shock at the rear work together to absorb bumps and improve wheel contact over uneven surfaces.
