C1 is equipped with a powerful 1100W brushless DC motor, paired with a 5-level Pedal Assist System (PAS). In PAS Level 1, the controller delivers up to 90Nm of torque, while in PAS Level 5, the bike reaches speeds of 28+ MPH.
The motor uses a sine-wave controller design, providing smoother and more responsive power engagement during pedal assist. With a rotational speed of over 4,000 RPM, this brushless DC motor offers low interference, low noise, smooth operation, high RPM performance, and excellent heat resistance.
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.
The MAX series is built on a high-strength die-cast alloy frame, delivering confidence and control wherever you ride. Protected by advanced anti-corrosion treatment, it’s made for the long haul.
Under sunlight or city lights, the exclusive purple finish comes alive—flowing between pink, violet, and shimmering iridescence. Not just a bike, a statement in motion.
Combo deals offer greater savings—ride together, double the fun.
For enhanced riding stability, the MAX version is equipped with 26" × 2.6" all-terrain tires, delivering a perfect balance between agility and range.
Each tire is reinforced with a puncture-resistant liner, giving you added confidence on every ride.
