Aipas M1 Pro
Comfort on rough roads and gravel, with an easy step-through frame.

Hunting, backcountry trails and steep hills, for riders 5 ft 4 in to 6 ft 8 in.
Our pick: Most power (two motors). The FREESKY Dual Motor Fat Tire is a fat tyre e-bike with 4000W of peak motor power and 1200Wh of battery, about $1,000 on Amazon. It suits hunting, backcountry trails and steep hills, for riders 5 ft 4 in to 6 ft 8 in. The catch: at 34 mph and 4000W it is legally more like a moped than a bicycle in most states: not allowed on most bike paths.

Specs are the maker's own, from the Amazon listing. Real range is our estimate from the battery size.
At 34 mph and 4000W it is legally more like a moped than a bicycle in most states: not allowed on most bike paths.
Four-inch tyres that float over sand, snow and gravel. Heavier and slower to pedal on the road.
Most power (two motors). Two 2000W motors, 210Nm combined. 48V 25Ah (1200Wh) battery. The catch: At 34 mph and 4000W it is legally more like a moped than a bicycle in most states: not allowed on most bike paths.
The listing claims up to 105 miles. With a 1200Wh battery, expect about 40 to 60 miles in real riding (roughly 20 to 30 watt-hours per mile with a mix of pedalling and throttle). Hills, cold weather, heavier riders and throttle-only riding cut it further.
The listing gives 34 mph. That is above the 28 mph Class 3 limit, so in most US states it counts as a moped or motor vehicle at full speed: set it to your local limit to ride on bike paths.
Hunting, backcountry trails and steep hills, for riders 5 ft 4 in to 6 ft 8 in. The maker gives a rider height of 5 ft 4 in to 6 ft 8 in.
