Overview

The Fly Brother Foldable Fat Bike is a Class 2 electric bicycle designed for versatile riding conditions. Its fat tires provide enhanced stability and traction on varied terrains, and its foldable frame facilitates convenient storage and transportation. The electric pedal-assist system offers increased power and range for recreational and commuting purposes.

Key Features

The bike features 4-inch wide tires, providing increased surface area and lower ground pressure, enabling confident riding on sand, snow, and uneven surfaces. The 750W electric motor delivers pedal assistance, allowing riders to maintain speed and climb inclines with reduced effort. The motor is integrated into the rear hub, providing efficient power transfer. The folding frame utilizes a central hinge mechanism, allowing the bike to be compacted for storage in smaller spaces. The battery pack is typically a lithium-ion type, chosen for its energy density and lifespan. Battery capacity (measured in Amp-hours or Watt-hours) determines the bike's range per charge. The bike also includes a standard Shimano drivetrain offering a range of gears.

Design & Build

The frame is constructed from a high-strength alloy, selected for its balance of durability and weight. The folding mechanism is designed for ease of use and secure locking in both the folded and unfolded positions. Ergonomic considerations include adjustable seat height and handlebar position to accommodate a range of rider sizes. The tires are mounted on robust alloy rims for added strength and durability in off-road conditions. Braking is typically handled by mechanical disc brakes for reliable stopping power in varied weather conditions.
