Heybike – Brawn Ebike w/ 65mi Max Operating Range & 28 mph Max Speed-for Any Terrain-UL Certified – Green

Heybike Brawn eBike HBK-BRAWN-GN

The Heybike Brawn is an all-terrain fat-tire e-bike built for rougher rides and higher loads, with up to 65 miles of range, a 28 mph top speed, and hydraulic braking.

Built for Off-Road and Mixed-Terrain Riding

The Brawn is positioned as an all-terrain e-bike, with 26 x 4-inch fat tires and a more rugged setup than a typical commuter model. That makes it better suited to dirt, gravel, uneven paths, and rougher mixed-surface routes where stability and traction matter more. It is a stronger fit for riders who want to explore beyond paved streets without moving to a far more specialized machine. The bike is clearly designed around versatility in tougher riding conditions.

Long-Range Battery for Bigger Ride Plans

Heybike rates the Brawn for up to 65 miles of range and uses a 48V 18Ah battery, giving it the kind of endurance that supports longer off-road rides, utility use, and more ambitious weekend trips. That larger battery also helps the bike handle heavier-duty use without constant charging interruptions. For riders using a fat-tire bike as more than an occasional fun ride, that extra battery capacity matters. It supports the Brawn’s more capable overall personality.

750W Motor with Trail-Ready Power

The Brawn uses a 750W motor and is listed with an 80Nm torque figure in Heybike’s own comparison materials. That gives it the power to support climbs, heavier riders, and more demanding terrain while still staying within a familiar hub-motor format. It is built to feel stronger and more capable than a basic city bike, especially under load or on rougher routes. For riders who care about trail confidence, that added output is a key part of the package.

Hydraulic Brakes and Higher Payload Support

Heybike supports the Brawn with hydraulic brakes, which is especially important on a larger fat-tire bike intended for all-terrain riding. A 400-pound payload rating also makes the bike more suitable for heavier riders or for adding cargo and accessories to the frame and rear rack system. Those details make it more than just a recreational toy. It is built to handle demanding use with more control and carrying ability.

Designed for Riders Who Want More Capability

The Brawn is a good fit for riders who want a fat-tire e-bike with more range, more ruggedness, and more terrain flexibility than a standard commuter e-bike can offer. It also works well for riders drawn to a bigger-frame, adventure-oriented style without moving to a much more expensive specialty e-bike. With app compatibility, accessory support, and a stronger build focus, it feels positioned as a more capable all-around platform. It is designed to go beyond basic everyday riding.
