BRZ Thunder Pro 72V 5000W Electric Dirt Bike – Big Wheel 19”/16”

5000W peak power. 72V. 53MPH. Bigger wheels. Bigger capability. ⚡🏁

The BRZ Thunder Pro 72V 5000W Big Wheel is built for riders looking for serious electric performance combined with a larger, more capable off-road chassis.

Powered by a 2000W QS brushless motor producing up to 5000W peak power, the Thunder Pro delivers strong acceleration and instant electric response, with a claimed top speed of up to 85km/h / 53MPH*.

The big-wheel 19”/16” setup gives the bike a larger off-road footprint than the 17”/14” version, making it particularly well suited to riders looking for a bigger bike and increased capability across uneven terrain.

A 72V 30Ah lithium battery, hydraulic suspension and front and rear hydraulic disc brakes complete a package designed for serious off-road riding.

🏁 5000W PEAK POWER

At the heart of the Thunder Pro is a 2000W QS brushless motor capable of producing up to 5000W peak power.

The motor provides the instant response and strong electric torque you’d expect from a high-performance electric dirt bike, with power delivered to the rear wheel through a chain-drive system.

There’s no clutch and no traditional gear changes to worry about.

Twist the throttle and the electric drivetrain responds instantly.

🔋 72V 30Ah LITHIUM BATTERY

The Thunder Pro is equipped with a substantial 72V 30Ah lithium battery, providing the energy required by its high-output drivetrain.

Battery Specification

Voltage: 72V
Capacity: 30Ah
Charger: 84V 5A
Claimed range: approximately 80–100km*

Actual range will vary depending on rider weight, riding style, terrain, speed, temperature, battery condition and other riding conditions.

The manufacturer’s published charging time is approximately 4–6 hours. 

🚀 UP TO 53MPH

The BRZ Thunder Pro has a manufacturer-listed top speed of approximately 85km/h / 53MPH*.

That’s serious performance for an electric dirt bike, so rider experience, suitable protective equipment and a suitable riding environment are essential.

The bike should only be operated by someone with the appropriate ability and understanding of a high-performance electric dirt bike.

 

🛞 BIG-WHEEL 19”/16” SETUP

The biggest difference between this version and the smaller Thunder Pro is right there in the name:

19” FRONT / 16” REAR

The larger wheel combination gives the bike a bigger off-road footprint and helps it carry momentum across uneven terrain.

The setup is particularly suited to:

• Dirt tracks
• Woodland trails
• Loose surfaces
• Uneven ground
• Off-road tracks
• More demanding terrain

🏁 HYDRAULIC SUSPENSION

The Thunder Pro features hydraulic suspension front and rear.

Front Suspension

The hydraulic inverted front fork is designed to improve control and damping when riding across uneven terrain.

Rear Suspension

The hydraulic rear damping suspension works with the larger wheel setup to help keep the bike controlled over bumps, ruts and changing surfaces.

Together, the suspension system gives the Thunder Pro the off-road capability you’d expect from a proper dirt-bike chassis.

🛑 HYDRAULIC DISC BRAKES

Performance isn’t just about acceleration.

The Thunder Pro features hydraulic disc brakes front and rear, providing strong and controlled stopping performance.

Hydraulic braking gives the rider the control needed when approaching corners, changing terrain or bringing the bike back under control.

🖥️ SMART LCD DISPLAY

The Thunder Pro features a smart LCD display providing key riding information at a glance.

The display provides information including:

• Current speed
• Battery level
• Ride mode
• Trip information

So you can keep track of the bike’s important information while keeping your attention on the trail.

📐 BIGGER BIKE. BIGGER PRESENCE.

The 19”/16” wheel combination gives the Thunder Pro a larger stance than the small-wheel version.
