CHAOZHU BF 8FUN G062 Fat Bike Rear Hub Motor Review

For fat bike enthusiasts looking to electrify their off-road adventures, the CHAOZHU BF 8FUN G062 48V 1000W Rear Hub Motor is a compelling choice. Designed specifically for fat tires with a 175mm dropout, this thread-on motor combines robust power, seamless compatibility, and reliable durability—key factors for anyone who wants to tackle tough terrain without sacrificing performance.

Performance: Power That Meets the Trail

At its core, the G062 is built for riders who demand uncompromising power. With a rated power of 1000W and a peak torque of 85 N.m, paired with a 1:5 reduction ratio, it delivers the kind of propulsion that turns challenging trails into enjoyable adventures. Let’s break down what these numbers mean for real-world riding:

The 1000W rated power ensures consistent performance even at high speeds, while the 85 N.m peak torque is the star of the show—especially for climbing. Whether you’re navigating a steep, muddy trail that used to require pushing, powering through deep sandy dunes, or plowing through light snow, the torque provides immediate, sustained force that keeps you moving forward. Unlike some hub motors that feel “weak” at low speeds or struggle with heavy loads, the 1:5 reduction ratio optimizes power delivery for the low-speed, high-torque demands of off-road riding. This means no lag when you hit the throttle—just smooth, instant power that lets you tackle technical sections with confidence.

Rear hub motors are often preferred for off-road riding because they provide better traction than front hub motors, and the G062 is no exception. The rear wheel’s weight (combined with the fat tire’s wide contact patch) ensures the motor’s power is transferred to the ground efficiently—no spinning wheels or lost momentum on loose terrain. For example, if you’re riding on a sandy beach, the rear hub motor will grip the sand better than a front motor, letting you power through without getting stuck. Similarly, on a muddy trail, the rear weight distribution helps keep the tire planted, so you can climb without slipping.

The 48V system is another smart choice. It strikes a balance between power and practicality—enough voltage to deliver strong performance without requiring a bulky, heavy battery. Most 48V batteries are compact enough to fit on a fat bike’s frame or rack, so you won’t have to sacrifice cargo space for range. And because 48V systems are common in e-bikes, you’ll have plenty of options when it comes to choosing a battery that fits your needs.

Compatibility: Designed for Fat Bikes

One of the biggest challenges of e-bike conversions is compatibility, but the G062 takes the guesswork out of the process. It’s designed specifically for fat bikes with a 175mm dropout—the standard width for most modern fat bikes, including popular models from Surly, Salsa, and Moosejaw. This means you won’t have to modify your frame to fit the motor—just remove your existing rear hub and install the G062.

The thread-on flywheel is another standout feature for DIY converters. Unlike splined motors, which require specific adapters to attach to your bike’s hub, the thread-on design lets you screw the motor directly onto your rear wheel—saving time, money, and frustration. If you’ve ever done an e-bike conversion before, you know how frustrating it can be to find the right adapter for a splined motor. The G062 eliminates that problem with a simple, secure thread-on connection.

Disc brake compatibility is non-negotiable for fat bike riders, and the G062 delivers. It’s designed to work with both mechanical and hydraulic disc brakes, so you won’t have to change your existing brake setup. This is a big plus because fat bikes are heavy, and you need reliable stopping power to match the motor’s increased speed. Whether you’re descending a rocky trail or braking suddenly to avoid a tree root, the disc brakes will bring you to a stop safely—no compromises.

Efficiency & Durability: Built for Long-Term Use

Efficiency is key for e-bike motors, especially if you’re planning long rides. The G062 has an efficiency rating of over 80%, which means more of the battery’s power is converted into motion—translating to longer range per charge. For example, if you’re using a 14Ah 48V battery, you can expect to get around 25-30 miles per charge (depending on terrain and riding style). That’s more than enough for most weekend adventures, and it means you won’t have to cut your ride short because of a dead battery.

Durability is another area where the G062 excels. It’s made from high-quality aluminium, which is both lightweight and strong enough to withstand the rigors of off-road riding. The sealed casing keeps out dirt, water, and dust—critical for fat bike riders who often venture into muddy, wet, or dusty terrain. You can ride through a rainstorm, plow through a mud pit, or even cross a shallow stream without worrying about damaging the motor’s internal components.

The motor’s operating temperature range is also impressive: -20℃ to 40℃. This means it’s suitable for year-round riding, whether you’re hitting the trails in the middle of a British winter (where temperatures can drop below freezing) or the height of summer (when trail temperatures can soar). You won’t have to worry about the motor overheating on a hot day or freezing up in the cold—just reliable performance, no matter the weather.

Noise is another factor that’s often overlooked but makes a big difference in ride quality. The G062 operates at less than 55dB—quieter than most household appliances. No loud whirring to drown out the sound of birds, wind, or your riding buddies’ conversation. Just smooth, quiet power that lets you enjoy your ride without drawing unnecessary attention. One user put it best: “I was worried the motor would be loud, but you can barely hear it over the sound of my tires on the trail. It’s like having a silent partner that helps me climb hills.”

Package & Support: Everything You Need to Get Started

The G062 comes with everything you need to start your e-bike conversion: the motor itself, an 800mm cable, and a choice of G9.12 or G11.6 male plugs. The cable is long enough to reach most controllers (which are usually mounted on the frame or handlebars), and the plug options mean you can pair the motor with most standard e-bike controllers. This flexibility is a big plus if you’re using an existing controller or buying a new one—you won’t have to splice wires or buy adapters.

Installation is straightforward for anyone with basic bike maintenance skills. The thread-on design means you don’t need any special tools—just a wrench to remove your existing rear hub and screw on the G062. But if you’re new to e-bike conversions, CHAOZHU’s support team is on hand to help. They offer step-by-step guides, video tutorials, and personalized troubleshooting advice to ensure you get your motor up and running without hassle. One user shared: “I’m not very good with tools, but the CHAOZHU team walked me through every step. They even sent me a video tutorial when I got stuck on the wiring. I had the motor installed in a couple of hours—easy peasy.”
