Hardtail or full suspension
A hardtail has a suspension fork and a rigid rear. It is lighter and simpler, and fine for gravel and dirt paths; the Gyroor EB262 and EB263, the Hiboy P6 and the Speedway Riders Q3 are built this way. Full suspension adds a rear shock that keeps the back tire gripping over roots and ruts. The Segway Xafari has 80 mm of travel at the front and 70 mm at the rear, the ASAP Pioneer 90 mm and 100 mm, and the Hiboy EX11 pairs an 80 mm lockout fork with a 4-link rear end.
Off-road tread or fat tires
The Gyroor mountain bikes run 26 x 1.95-inch off-road tires, the classic choice for packed dirt and gravel. Fat tires, 4 inches wide on the Hiboy P6 and EX11, the ASAP Pioneer and the Q3, float over sand, snow and loose ground and add comfort, at the cost of weight. The Xafari sits between, on 26 x 3.0-inch Kenda tires. More in fat tire electric bikes.
Torque and brakes
Loose climbs need torque more than top speed: Hiboy lists 90 Nm for the EX11, Segway 80 Nm for the Xafari and ASAP 75 Nm for the Pioneer. Descents need strong brakes, and the Xafari, EX11 and Q3 use hydraulic discs, which need less hand effort than the mechanical discs on the Gyroor models.
Battery, weight and water
Rough ground uses more energy than pavement, so plan with margin. The biggest packs here are 960 Wh on the Q3, 936 Wh on the Xafari and 864 Wh on the EX11. Suspension and fat tires add weight: the EX11 weighs 99.2 lbs against 49 lb for the Gyroor EB262. For mud and puddles, check the IP rating; Gyroor lists IP65 for its mountain bikes.
Where you can ride
Trail access differs by state, park and land manager: some trails welcome e-bikes, some allow only pedal assist without a throttle, and some allow none. Check the rules before you ride. Moped-style off-road models such as the Segway Xyber are on the electric mopeds page.
