The AIMA Big Sur is a fat-tire all-terrain eBike designed for commuting, recreational riding, paved roads, gravel paths, dirt trails, and other mixed-terrain environments.
Its 26" × 4" fat tires, suspension fork, and powerful motor provide comfort, traction, and stability across a wide variety of riding conditions.
The Big Sur is delivered as a Class 2 eBike with a top assisted speed of 20 MPH.
Depending on local regulations and dealer configuration, certain models may be configured for Class 3 pedal-assist operation. Please contact your authorized AIMA dealer for details.
Actual riding range depends on many factors, including rider weight, terrain, tire pressure, weather conditions, assist level, throttle usage, and cargo load.
Under typical riding conditions, riders can expect up to 60 miles of range on a full charge.
For maximum range, use lower assist levels, maintain proper tire pressure, and keep the battery properly charged.
The Big Sur is equipped with a 750W BAFANG rear hub motor designed to provide strong acceleration, hill-climbing capability, and reliable performance across a variety of riding conditions.
The Big Sur features a torque sensor.
A torque sensor measures rider pedal input and delivers motor assistance roportionally, creating a smoother, more natural riding
experience and improved efficiency.
The Big Sur is designed to accommodate a wide range of rider heights.
Please refer to the size chart on the product page or visit your authorized AIMA dealer for a professional fit recommendation.

The Big Sur's fat tires, suspension fork, and powerful motor make it well suited for gravel roads, dirt paths, and light off-road riding.
Always ride within your skill level and avoid terrain beyond the intended use of the bicycle.
The recommended tire pressure range is printed on the tire sidewall.
For maximum efficiency on pavement, riders typically use higher tire pressures. For improved comfort and traction on dirt, gravel, or uneven terrain, lower tire pressures may be appropriate.
Always remain within the pressure range specified on the tire.
Because the Big Sur uses large 26" × 4" fat tires and heavy-duty wheels, spoke tension should be inspected periodically.
