In-depth review
The M2 Pro shares the M1 Pro's 1,800 W peak motor, 110 Nm and 840 Wh battery but uses a step-over mountain frame rated for 500 lb, with 180 mm discs and a lockable fork.
It's heavy (90 lb by the bullets; the spec table says 114 lb). Aipas doesn't list the rated power or top speed on this listing. Owners report good range and build; one had a battery replaced by Aipas.
Sold by a third-party seller with a 1-year warranty.
