Bibuff GT600 Review: A Powerful Electric Dirt Bike with Impressive Full Suspension

The Bibuff GT600 is a high-powered electric dirt bike featuring a 72V system, 4,000W continuous motor power, 7,500W peak output, and full suspension designed for demanding off-road riding. With explosive acceleration, a striking motocross-inspired design, and a real-world full-throttle range of around 30 km, this machine delivers serious performance—but a concerning rear bearing issue needs attention.

Assembly and Build Quality

Assembling the Bibuff GT600 is relatively straightforward and takes around 20 minutes. The main tasks are fitting the front wheel, handlebars, and pedals. However, because this is a heavy machine, having a second person help with assembly and moving it around is a good idea.

Despite its substantial size and weight, the GT600 feels surprisingly nimble once you're riding it. The combination of a large frame and aggressive styling gives it a strong presence, making it look more like an electric dirt bike than a conventional electric bicycle.

The overall paintwork and finish also made a positive impression during the test. The frame looks substantial, the graphics are clean, and the bike has a premium appearance for its price category.

Motor Power and Acceleration

The Bibuff GT600 is equipped with a brushless motor rated at 4,000W continuous power and 7,500W peak power, operating on a 72V electrical system. These figures translate into extremely strong acceleration on the bike tested.

The most surprising characteristic is its low-end torque. With a fully charged battery, applying roughly half throttle or more can lift the front wheel off the ground with very little warning. Riders need to be prepared for this level of power, especially if they are accustomed to ordinary electric bikes.

During the test, the GT600 reached approximately 100 km/h. At these speeds, it behaves much more like a powered dirt bike than a typical e-bike. The bike arrived with its speed limited to 25 km/h, although that limit was unlocked during the video test.

This level of performance is exciting, but it also demands experience and careful throttle control. High-speed riding should only take place in suitable, legally permitted areas with appropriate protective equipment. The GT600's road legality will depend on its configuration and local regulations, so don't assume that its factory speed limit makes every version road-legal.

Full Suspension: A Major Highlight

The suspension system was one of the strongest aspects of the Bibuff GT600 during the test.

At the rear, the shock absorber felt well tuned, combining a relatively soft response with good resistance to bottoming out. The bike handled speed bumps, rough terrain, and hard landings impressively during testing. Even over uneven surfaces at speed, the rear suspension helped keep the ride controlled.

The front fork also performed well. From small bumps and curbs to rough off-road sections and jumps, it absorbed impacts effectively and helped the bike feel planted.

For a machine in this price category, the suspension performance was particularly impressive. Riders looking for an electric dirt bike for trails and rough terrain will likely consider this one of the GT600's biggest advantages.

However, strong suspension performance does not eliminate the need to inspect the wheels, bearings, and other critical components before riding.

Design, Display, and NFC Unlocking

The Bibuff GT600 has an aggressive, motocross-inspired appearance. Its large frame, clean graphics, and attractive finish give it plenty of visual presence.

The bike is available in pedal and footpeg configurations. The footpeg version has a cleaner dirt-bike appearance, while the pedal version retains bicycle-style components. The appropriate choice depends on your intended use and the legal requirements where you ride.

The display keeps things simple, showing essential information such as speed, battery level, distance, and riding mode. It is easy to read and straightforward to operate.

Another useful feature is the NFC unlocking system. In the test, tapping the NFC card woke up the bike quickly and reliably. This makes starting the bike convenient without relying on a conventional key.

Seat Comfort and Riding Position

The long seat is another positive feature. It provides plenty of room to move around while riding off-road and was surprisingly comfortable during extended test sessions.

The seat also has enough space for two people physically, although whether carrying a passenger is permitted or safe depends on the specific configuration and applicable regulations.

The handlebar grips performed well, too. They provided a secure hold without feeling excessively sticky, and they remained grippy even when the rider's hands became sweaty.

Together, the seat and grips contribute to a comfortable riding position for a bike designed around aggressive off-road use.

Brakes and Tyres: What You Should Know

One issue encountered during testing was the brake adjustment. The front brake was rubbing, and the rear brake also needed some adjustment. The problem was relatively quick to correct, but it is disappointing to find these issues on a new bike.

Before riding, check that both brakes operate correctly, that the rotors do not rub excessively, and that all fasteners are secure.

The GT600 uses aggressive, knobby tyres designed primarily for off-road terrain. They work well on dirt and loose surfaces, but they are less suited to regular asphalt or brick-road riding, where the tread may wear more quickly.

If your riding is mostly on paved roads, these tyres may not be the ideal choice. The bike is better suited to riders who intend to spend much of their time off-road.

Battery Removal and Charging

Removing the battery is less convenient than it could be. The process involves unscrewing a twist mechanism underneath the bike before removing the seat panel and pulling out the battery.

The procedure takes approximately 15 seconds, so it isn't especially time-consuming. However, a simpler latch-based design would make battery removal more convenient for regular charging or maintenance.

Charging takes around 4–6 hours, according to the test.

Real-World Battery Range

The Bibuff GT600 is built around performance rather than long-distance efficiency. During the test, riding at full throttle delivered a real-world range of approximately 30 km.

Riding more conservatively can extend the usable riding time, but the actual distance will depend on throttle input, terrain, rider weight, battery condition, and riding conditions.

For a high-powered electric dirt bike, the key consideration is whether the available range matches your intended use. Shorter off-road sessions may suit the GT600 well, but riders planning long-distance trips should factor in the need to recharge.

The Biggest Concern: Rear Bearing Safety

The most important issue identified during testing was a loose rear bridge bearing.

On the test bike, the bearing was slightly loose from the factory. After it was tightened, it became loose again. This is a significant concern on a machine capable of reaching high speeds and handling jumps and demanding off-road terrain.

A loose bearing or related rear-wheel assembly can affect stability and safe handling. This is not a minor cosmetic issue, and it should not be overlooked simply because the motor and suspension perform well.

My recommendation is to have the rear bearing and associated wheel assembly inspected and properly secured before riding. If the bearing becomes loose again, stop riding and contact the seller or manufacturer for a proper repair. Simply tightening it repeatedly may not address the underlying cause.

The GT600's suspension and motor impressed during the test, but this bearing issue raises questions about quality control and needs to be taken seriously.

Is the Bibuff GT600 Worth Buying?

The Bibuff GT600 offers an exciting combination of powerful acceleration, impressive full suspension, an aggressive design, and useful features such as NFC unlocking. Its off-road performance was a clear highlight, particularly the way the front fork and rear shock handled rough terrain.

There are compromises. The battery removal mechanism could be more convenient, the brakes needed adjustment out of the box, and the knobby tyres are better suited to dirt than regular road use. Most importantly, the rear bearing issue on the test bike needs to be resolved before the machine can be recommended with confidence.

Final Verdict: The Bibuff GT600 is a thrilling high-powered electric dirt bike with genuinely impressive suspension and acceleration. It has plenty of potential for off-road enthusiasts, but the rear bearing problem is a serious caveat. Check the rear wheel assembly carefully before the first ride, and make sure any recurring looseness is properly repaired. Its performance is exciting, but safety and mechanical reliability must come first.
