Aipas M1 Pro vs A2 Fat Tire
bike type and portability
The Aipas M1 Pro is a rigid step-through fat tire bike designed for stability and trail capability. It measures 80 inches in length and weighs 88 pounds. This configuration offers a solid platform for off-road use but requires more storage space. The Aipas A2 is a folding step-through model built for compact storage. It folds down to fit in SUVs, RVs, and most car trunks. At 65 pounds, it is significantly lighter and easier to transport. If you need to store the bike in a small apartment or carry it in a vehicle, the A2’s folding design is the clear practical advantage. If you prefer a rigid frame for rugged terrain, the M1 Pro is better suited.
motor power and speed
Motor output defines how each bike handles acceleration and steep inclines. The M1 Pro features a 1800W peak rear-hub motor with 110Nm of torque. This high power allows it to climb slopes up to 23 degrees and provides strong acceleration for trail riding. The A2 uses a 750W peak motor. While less powerful, it is tuned for a Class 3 experience, reaching speeds up to 28 MPH in pedal assist mode. The M1 Pro wins on raw power and hill-climbing ability, making it better for steep, uneven trails. The A2 wins on top speed and urban commuting efficiency, where lower power is often sufficient and legal.
battery capacity and range
Both bikes use 48V removable batteries, but the capacity differs significantly. The M1 Pro includes a 17.5Ah battery, which supports up to 85 miles of pedal-assist range. This larger capacity is ideal for longer weekend adventures or heavy trail use. The A2 comes with a 12.8Ah (614Wh) battery. It offers a real-world range of 30–50 miles, with a maximum of 62 miles in pedal assist mode. The M1 Pro provides substantially more range per charge. If your daily commute is short or you prioritize lighter weight over distance, the A2’s battery is adequate. For extended rides, the M1 Pro’s larger battery is the superior choice.
wheel size and tires
Wheel size affects stability, ground clearance, and maneuverability. The M1 Pro is equipped with wide 26 x 4-inch fat tires. These larger tires provide superior traction and stability on loose surfaces like gravel, dirt paths, and snow. They also offer greater ground clearance for off-road obstacles. The A2 uses 20 x 3-inch fat tires. While still wide, the smaller diameter makes the bike more agile and easier to handle in tight urban spaces. The 26-inch wheels on the M1 Pro are better for rough terrain. The 20-inch wheels on the A2 are better for city commuting and easier folding mechanics.
suspension system
Suspension impacts ride comfort on rough surfaces. The M1 Pro features full suspension, including an adjustable 100mm front fork and a rear shock absorber. This system absorbs bumps on pavement, gravel roads, and uneven trails, providing a smoother ride for the rider. The A2 has only front suspension. It lacks a rear shock, meaning impacts from the rear wheel are transferred more directly to the frame and rider. The M1 Pro offers significantly better comfort for off-road riding and rough roads. The A2’s simpler suspension is sufficient for paved city streets and light bike paths.
