Overview
The Seemoon is a dual-motor, step-through fat tire electric bike with a 52V 1040Wh removable battery, rated by the seller for up to 105 miles of range and a top speed around 38 mph.
This bike runs two motors that can be used together or separately across five working modes, from single-motor commuting to full dual-motor power for hills, plus a standard 7-speed pedal mode. Owners consistently describe it as heavier and more feature-loaded than pricier competitors, though a couple of buyers flagged a security gap since the bike can be started without a key, and one had trouble releasing the battery.
- Dual brushless motors with 160 Nm combined torque
- 52V 1040Wh removable, lockable battery
- 5 working modes from single-motor to dual-motor to walking assist
- 26x4.0 inch fat tires with front fork and seat spring suspension
Who it's for
Fits riders who want a heavy-duty, long-range fat tire ebike with real hill-climbing power and are comfortable buying an extra lock given the throttle can be engaged without a key. Less suited to riders chasing a lightweight bike or who need the fastest possible top speed, since actual reported speeds landed closer to 30-37 mph.

Performance notes
The dual brushless motors combine for 160 Nm of torque and can run as a single motor for daily commuting or both together for steep terrain, while the 52V 20Ah battery is rated for 35 to 105 miles depending on mode.
