FAQs

Please read our FAQs page to find out more.

Is the SEEMOON SM2 street legal in the United States?

Yes. The SM2 is designed to comply with U.S. federal e-bike regulations. By default, it operates in Class 2 or Class 3 mode with a 28 MPH speed limit, making it legal for most city streets and bike lanes. For off-road enthusiasts riding on private property, the speed can be unlocked to its full potential of 28 MPH. We always recommend checking your local state and municipal laws regarding high-speed AWD e-bikes.

How does the Dual-Motor AWD system benefit my ride?

The SM2 features a high-torque All-Wheel Drive (AWD) system that you can control via a handlebar switch. While single-motor bikes struggle on inclines, the SM2’s dual motors provide explosive acceleration and the power to conquer 30° steep hills. The AWD setup also offers superior traction and stability when navigating challenging terrains like loose sand, thick mud, or deep snow.

What is the real-world range of the 52V battery?

The SM2 is powered by a high-capacity 52V Grade-A lithium battery .

Pure Electric Mode (Throttle Only): Expect a range of 30-45 miles.
Pedal Assist Mode (PAS): You can achieve 80-100 miles depending on the assist level.
Note: Real-world mileage varies based on rider weight, wind resistance, tire pressure, and terrain.

Why are Hydraulic Oil Brakes essential for the SM2?

Safety is our priority. Since the SM2 can reach speeds up to 28 MPH, traditional mechanical brakes aren't enough. Our premium Hydraulic Oil Brakes provide massive stopping power with minimal finger effort. They offer shorter braking distances and consistent performance in wet or muddy conditions, ensuring you stay in control even during high-speed descents.

Is the SM2 comfortable for long off-road trips?

Absolutely. Unlike many rigid-frame e-bikes, the SM2 features a Full Suspension system (front hydraulic forks and rear dual shock absorbers). This setup acts like a "cloud" for your commute, soaking up high-impact bumps and vibrations. Combined with our ergonomic saddle, it protects your back and joints during long-distance or rugged off-road adventures.

What free gifts are included with my purchase?

To give you the best value in the U.S. market, every SM2 comes with a Free 7-Piece Gift Pack (Value over $200):

Professional Phone Mount
Multi-functional Data Cable
High-security Bike Lock
Portable Air Pump
Spare Inner Tube
Two Extra Pairs of Original Brake Pads
Portable Cooling Fan

How does shipping and the 2-Year Warranty work?
