Anyone who has to lift it.

In-depth review
The M1 Pro is a fat-tire bike you can step through: 26 × 4 in tires, a 100 mm fork and rear shock, and an 840 Wh battery for long rides. The motor is 750 W rated (1,800 W peak, 110 Nm), so it climbs well and stays within Class 3 limits.
It weighs 88 lb and the brakes are mechanical discs. Riders under about 5'5" may find it tall.
Owners consistently call it a lot of bike for the money; one reports repeated flat tires early on.
