Best folding e-bikes

The Mars 3.0 pulls harder than anything else on this list, with 95 Nm of torque from its 750W hub motor that yanks it away from stops and up hills even loaded down. At $1,199, it also carries a 624Wh battery and throttle control up to 20 mph, so you get motor, battery, and hauling capacity most bikes near this price can't match. The trade-off is weight: at 70 lb, it's not something you carry solo up a staircase, and Heybike doesn't publish the pack's voltage or amp-hours, so comparing it precisely to rivals is tough.

The Portola is the least expensive bike on this list at $945, yet it still comes with dual-piston hydraulic disc brakes and 180mm rotors for real stopping power. A throttle and a switchable class mean you can ride without pedaling or dial in more speed depending on the day. The 500Wh battery is on the small side for the class, so plan around a charge for longer outings, and the firm tires with no suspension mean rough pavement comes straight through to your hands.

The XP4 750 Long Range carries the largest battery on this list, 840Wh, enough to string together several days of commuting before you need an outlet. Its 750W motor and 85 Nm of torque pull a loaded bike up moderate hills without straining, and the frame still folds small enough for a car trunk or closet. At about 71 lb, though, treat the fold as a storage trick, not something you'll carry up stairs regularly.

The Fold 1 Plus is rated to carry more weight than any other bike on this list, 450 lb, which covers a rider plus panniers or a passenger without straining the frame. A 608Wh battery rated for up to 68 miles backs that up, and it pops out so you can charge it inside instead of hauling the whole bike to an outlet. Power comes from a cadence sensor rather than a torque sensor, so assist kicks in more abruptly than on some rivals, and there's no suspension to soften bigger potholes.

The Sonder weighs less than any other bike on this list, 48.72 lb, so folding it and lifting it into a trunk or up a flight of stairs is actually realistic. At $1,299 it still comes with hydraulic disc brakes and a Shimano 9-speed drivetrain, hardware many bikes at this price skip. The trade-off shows up on hills and long rides: the 250W motor and 40 Nm of torque work hard on steep climbs, and the 480Wh battery means more frequent charging.

The Portola C1 backs up its price with real hardware: a 750W hub motor and 65 Nm of torque, enough to get a loaded bike up to speed on flats and moderate hills. A 643Wh battery supports a claimed 30 to 50 miles of range, and 180mm hydraulic disc brakes stop it hard even loaded or wet. There's no throttle, so assist only comes while you pedal, and the 20-inch wheels feel busier over rough pavement than full-size wheels would.

The Slate is built for gravel, dirt roads, and loose surfaces, and at 54 lb it's light enough for off-road use that loading it onto a car rack is a one-person job. A throttle plus 25 mph pedal assist lets you cruise without pedaling or push the pace, and the price keeps off-road riding affordable. The 70 Nm motor works hard on steep, loose climbs, and Mokwheel doesn't publish a suspension spec, so don't expect the 3-inch tires alone to smooth out rocky trails.

Daily commuting gets a torque boost from the Horizon's 750W hub motor, which puts out 80 Nm to make hills and loaded panniers manageable from the first pedal stroke. A 692Wh battery is good for up to 55 miles of claimed range, so most riders only plug in once or twice a week. At 79 lb it's heavy even by fat-tire standards, so getting it onto a car rack usually takes two people, and Heybike's spec sheet doesn't confirm whether it has a throttle, so check the current listing if that's a must-have.
