What our Experts Think
-
True high-speed off-road performance: The F18 delivers a verified 46 MPH top speed, placing it in the high-performance electric dirt bike category rather than a standard commuter e-bike.
-
Strong mid-drive power system: A 6000W peak mid-drive motor provides fast acceleration and consistent torque delivery across uneven terrain.
-
Serious climbing torque: Up to 245 N·m torque gives it strong hill-climbing ability and confident low-end pull on dirt, sand, and trails.
-
Balanced off-road control: Mid-drive + chain transmission improves traction and weight balance compared to hub-motor designs, especially in technical riding conditions.
-
Long ride capability: The 60V 30Ah battery system supports up to 60 miles range, suitable for extended trail sessions and all-day riding.
-
Built for aggressive terrain: Full suspension and hydraulic disc brakes are tuned for stability, shock absorption, and controlled stopping at high speed.

Maintenance Tips
- Charge the 60V battery between 20–80%; avoid full discharge to extend battery lifespan and maintain consistent range
- Use the original charger only for safe, stable charging cycles
- Clean and lubricate chain and drivetrain regularly, especially after off-road, mud, or sand riding
- Check and adjust chain tension frequently due to high-speed mid-drive torque stress
- Inspect hydraulic brakes and pads often; replace early for safe stopping at 46 MPH
- Keep suspension, frame bolts, and wheel spokes tight and clean to handle rough terrain impact
- Maintain proper tire pressure and tread depth for grip, stability, and reduced battery strain
- Avoid high-pressure washing; protect motor, controller, and connectors (IPX5 rated)
- Allow motor and battery to cool after long rides or climbs to prevent overheating
- Store in a dry, shaded place and keep battery at 50–70% charge during long-term storage
