Exceptional Motor System and Power of the 72v Electric Dirt Bike

This 72v Electric Dirt Bike runs on a PMSM (Permanent Magnet Synchronous Motor), known for its efficiency and reliability. The rated power is 12 kW, while maximum power output can reach 13.5 kW. A high-resolution magnetic encoder integrated in the motor ensures precise control and smooth acceleration for excellent riding experience. This motor system comes with an IP67 protection level, making it resistant to dust and water—ideal for rough dirt terrain rides.

Battery and Charging Features

Equipped with an NCM lithium battery, this electric dirt bike offers both high security and semi-solid state technology. The battery pack has a capacity of 74V and 50 Ah, supported by an advanced Battery Management System (BMS) and anti-shock features. It also meets stringent IP67 protection standards, ensuring durability and reliability. The battery life includes a charging cycle capacity of 1500 cycles or an estimated longevity of 26 months.

The 74V/15A charger supports 3C fast charge technology, allowing charging times of less than 3 hours. This fast charging feature helps riders get back on the trails quickly, minimizing downtime and maximizing ride time.

Advanced Controller and Low Voltage Components

The controller employs FOC (Field-Oriented Control) technology, providing smooth power delivery and efficient electric motor management. It operates at 74V electromagnetic voltage with an IP67 protection rating, prepared to withstand harsh off-road conditions. The bike includes a 3.2-inch TFT screen that is waterproof and carries an IP67 certification, giving riders clear visibility of vital ride data even in wet conditions.

The headlight is crafted from an Allium shell with CNC machining and anodic oxidation treatment. It features a high-brightness triple lens for superior illumination. A mechanical electric door lock also adds a layer of security, ensuring your electric bike is safeguarded when parked.

Top-Quality Brake System and Drive Components

Safety and control are vital, and this dirt bike’s braking system reflects that. The front brake uses a hand brake mechanism with a 9" disc and a 4-piston caliper from "TSK." DOT oil tubes guarantee reliable stopping power under demanding conditions. The rear brake has a similar handbrake setup with a single piston, also using DOT oil tubes for dependable performance.

The suspension system focuses on durability and ride quality. The front suspension uses “FAST” technology, featuring an internal tube diameter of 1.4" and a travel length of 9.4". Adjustable compression and recovery damping enhance ride comfort. External CNC tubes and forged 6061 aluminum components add strength and resilience to the construction.

Rear Suspension and Tires

The rear suspension also utilizes “FAST” brand components with a 3" travel length. It incorporates 6061 forged aluminum parts and CNC-finished forks for enhanced durability. Riders can adjust compression and recovery damping to tailor the suspension to their preferences.

The bike rolls on CST tires sized 80/100-19 on both front and rear wheels. These are mounted on UNISON 1.6×19 7075 aluminum rims, offering a balance of rugged traction and lightweight performance. The main and side frame are crafted with a welding combination of integrated 6061 forging and coated with a baking varnish for extra protection and style.

Reliable Transmission and Energy Regeneration System

Power transfer is smooth and efficient thanks to the transmission setup. The system uses a 428HHD-114 chain paired with a two-stage deceleration gearbox, featuring a speed ratio of 2.467. Front and rear chain sprockets measure 428-13T and 428-50T, respectively, for excellent torque delivery.

The bike also includes a manual energy regeneration function with four adjustable levels (I, II, III, IV). This feature lets riders optimize energy recovery during rides, increasing battery life and overall efficiency of the electric bike.
