Overview
Aipas' M2 Max is a 26x4.0-inch fat-tire electric mountain bike with an 1800W peak motor, air suspension and hydraulic disc brakes, positioned as an upgrade over the standard M2 Pro's rear suspension.
The air suspension system, adjustable up to 250 PSI, is specifically described as an upgrade from the M2 Pro's standard suspension, so buyers comparing Aipas models should note that distinction. Hydraulic disc brakes with carbon-ceramic pads are used here rather than the mechanical brakes common on similarly priced fat-tire ebikes, which the listing credits with shorter stopping distances. At around 90 lbs and rated for riders about 5 feet 8 inches to 7 feet 6 inches tall, it's built for larger riders and heavier-duty use.
- 1800W peak motor, 48V 17.5Ah removable battery
- 26x4.0-inch fat tires for all-terrain traction
- 7-speed gearing with 5 pedal-assist levels
- Arrives 95% pre-assembled, 365-day warranty
Who it's for
Suited to taller or heavier riders who want a fat-tire mountain ebike with hydraulic braking and adjustable air suspension for rougher trails. Less suited to shorter riders, given the tall fit range, or anyone prioritizing a lighter bike.

- Hydraulic disc brakes with carbon-ceramic pads for stopping power
- Air suspension adjustable up to 250 PSI

Performance notes
The 1800W peak brushless hub motor delivers up to 110Nm of torque, rated for climbing slopes up to 30 degrees, with power managed across 5 pedal-assist levels and 7-speed gearing.

Front and rear hydraulic dual disc brakes with carbon-ceramic pads are said to shorten braking distance by up to 30 percent versus mechanical brakes, paired with an air rear suspension adjustable to 250 PSI and 41mm of travel.
