Aipas M1 Pro & M2 Pro

In this aipas m1 pro & m2 pro review, the Aipas M1 Pro & M2 Pro is the long-range fat-tire touring pick in our 2026 electric mountain bike guide, ranked fourth of seven. It pairs a 48V 17.5Ah removable battery (840 watt-hours) with an 1800W peak rear-hub motor, and the listing rates pedal-assist range at up to 85 miles. Amazon shoppers give it 4.5 stars from 109 ratings, and it sells for $1,747.99. The platform comes in two versions, an M1 and an M2, both built on the same frame, motor, and battery. This bike suits riders who want to cover long weekend miles on gravel, sand, and snow. It does not suit anyone who needs a light bike or hydraulic brakes.

On the road, the 1800W peak motor and 110 newton-meters of torque push the Aipas M1 Pro & M2 Pro up climbs the listing rates at up to 23 degrees, which means steep gravel grades and snow-covered trails stay rideable. For example, five pedal-assist levels let you dial effort down for a long flat cruise and up when the surface turns soft. Meanwhile, a 100mm adjustable front fork and a rear shock soak up washboard gravel and root-rutted singletrack. Dual 180mm mechanical disc brakes with metal pads slow a 90-pound bike on descents, though hydraulic brakes bite harder. The 7-speed freewheel with a trigger shifter handles gearing, the display shows speed, mileage, battery level, and PAS, and a USB charging port sits beneath the handlebar controller. The 26 x 4-inch tires carry you over sand and packed snow.

As a result, $1,747.99 buys battery capacity that most fat-tire ebikes in this guide do not match, and the removable pack lets you charge indoors or at a campsite outlet. Even so, that value comes with weight: at about 90 pounds with a high carbon steel frame, the Aipas M1 Pro & M2 Pro is hard to lift onto a rack or up stairs. By contrast, the FREESKY Warrior Ultra and the Aipas M2 Max add hydraulic brakes, which matter on long descents. The warranty also runs just 1 year. That said, if your rides are long, mostly on the ground, and often on gravel or snow, the Aipas M1 Pro & M2 Pro is the one to get in this price range.
