Motor 1800W Power

The M1 Pro features a 1800W BLDC motor. The motor is equipped with a 5-level pedal assist system (PAS). At level 1 PAS, the controller can deliver a torque of up to 110 Nm, while at level 5 PAS, the speed can reach 36MPH or higher. The motor utilizes a sinusoidal wave structure and can rotate at a speed of 4478 revolutions per minute within one minute. The BLDC motor boasts low interference, low noise, smooth operation, high speed, high temperature resistance, and a longer lifespan (over 200,000 hours), ensuring stability and reliability in various complex environments and prolonged riding sessions.

Equipped 48V 17.5Ah battery

At Aipas, battery safety is our top priority. Each battery pack is engineered with a scientifically optimized internal layout and certified to meet MSDS, UN38.3, UN3171, UN3480, and SGS Certified UL2271. Our thermal safety protocols go far beyond industry norms—ensuring zero risk of open flames or thermal runaway even under temperatures as high as 149°F. An integrated thermal protection controller automatically shuts off power in case of overheating, giving you complete peace of mind and reliable protection on every ride.

Dual Hydraulic Brakes

The Max is equipped with a dual hydraulic braking system, paired with high-performance brake pads made from a 30% carbon fiber and ceramic composite. This setup achieves the perfect balance between powerful braking and quiet operation. Compared to standard braking systems, it delivers 60% more braking power and reduces stopping distance by 30%, ensuring top-tier safety and confidence on every ride.

Air Pressure Adjustable Suspension

The Max version brings a major upgrade in comfort, featuring a high-performance air suspension system adjustable up to 250 PSI. Crafted from 6061 aircraft-grade aluminum alloy, it’s both strong and lightweight. Compared to a non-rear-suspension design, vibration is reduced by up to 51%, with a 41mm suspension travel. Whether you prefer a smooth, cushioned ride or a firm, stable feel, the Max lets you fine-tune your suspension for the perfect balance of comfort and control.

The front headlight features a lens design with three high-intensity LED bulbs, offering approximately 30% more brightness than standard headlights on the market, with an illumination range of up to 100 feet. It also integrates a horn module for added convenience. The rear light is equipped with a red emergency LED bulb. At night, the lights can be set to stay on continuously, and the tail light will automatically flash when the brakes are applied, enhancing safety.
