Overview
An electric mountain bike built around a 1800W peak rear hub motor, a 48V 17.5Ah removable battery and an upgraded air rear suspension adjustable up to 250psi, paired with hydraulic dual disc brakes and a 7-speed drivetrain.
This is the Max tier of the Aipas M1 line, distinguished from the standard M1 Pro mainly by its air suspension rather than a coil setup. Nearly every review in this batch is five stars, and several buyers mention pairing it with the smaller M2 model as a two-bike order, worth knowing if you are comparing the lineup.
