Onyx ST FAQs

What is an all-terrain fat tire electric bike?

An all-terrain fat tire electric bike is an e-bike equipped with extra-wide tires—usually between 3.8 to 4.8 inches—and a powerful motor system, built to handle various terrains such as sand, snow, mud, mountain trails, and city roads. The fat tires offer superior traction and shock absorption for a smoother, more stable ride. Combined with electric assist, it allows riders to conquer hills, rough surfaces, and unpredictable conditions with ease—making it a truly versatile bike for both urban and off-road adventures.

What is a Mid-Drive Motor?

A mid-drive motor is installed at the bike’s bottom bracket, directly driving the crank and utilizing the gear system to optimize power output. Compared with a hub motor, it offers higher efficiency and a more natural riding experience.

What is the difference between a mid-drive motor and a hub motor?

  • Mid-drive motor: Provides stronger torque, better climbing performance, and more balanced weight distribution. Ideal for mountain riding and long-distance trips.
  • Hub motor: Features a simpler structure and lower cost, making it suitable for flat-road commuting.
