Rad Power Bikes RadExpand 5 Folding E-Bike

The RadExpand 5 is Rad's folding bike: 20x4 fat tires, a 750W motor, a 48V 14Ah battery, a low step-through folding frame and a rear rack. It is a little lighter than the old RadMini it replaced and much easier to mount. It folds for RV bays and trunks rather than for carrying. Compared with a Lectric XP it costs more and has a rigid fork, but it gets Rad's accessory catalog and the same 48V platform as the rest of the lineup, which matters if you already own a Rad. Mechanical disc brakes are the main spec shortfall at this price.

About Rad Power Bikes

Rad Power Bikes, based in Seattle, was the first direct-to-consumer e-bike brand to reach mass scale in the US, and its RadRover fat bike, RadCity commuter, RadRunner utility bike and RadWagon longtail are among the most common e-bikes on American streets. The current generation adds hydraulic brakes and semi-integrated batteries, and the accessory catalog (racks, baskets, passenger kits) is the deepest of any direct brand.

Lectric XP 3.0 Folding E-Bike

The XP 3.0 is the bike that made Lectric the best-selling e-bike brand in the US. It is a 20x3 folding bike with a 500W motor (higher peak), a 48V battery, hydraulic brakes, a suspension fork, fenders, a rack and lights, shipped fully assembled in a box. It is heavy for a folder, the cadence sensor makes assist a little abrupt, and the stock battery is on the small side (a long-range pack is offered). What it does better than anything at the price is arrive ready to ride, hold up, and have a huge owner community for parts and advice. Lectric has since released newer XP generations, but the 3.0 remains widely available.

Heybike Ranger S Folding Fat Tire E-Bike

The Ranger S is Heybike's step-through folder, which makes it a better fit than the Mars for riders who do not want to swing a leg over a top tube. It runs the same 750W class of motor on 20x4 tires, comes with a rear rack and fenders, and has a front suspension fork. The step-through folding frame flexes a little more than a step-over, which you will notice at higher speeds. Range is solid for the class. It is a sensible choice for someone who wants a fat-tire folder for errands and neighborhood rides and wants easy mounting more than outright stiffness.

Best for: Riders who need a step-through folder · Errands with a rack and panniers · RV and condo storage

Aventon Sinch.2 Folding Fat Tire E-Bike

The Sinch.2 is a folding bike with 20x4 fat tires, a 500W motor and, unusually for a folder, a torque sensor. The frame is a step-through design that is easier to swing a leg over than most folders, and the 672Wh battery sits inside the main tube. It folds, but it is heavy, so think of it as a bike that fits in an SUV or RV bay rather than one you will carry onto a train. Fenders and a rear rack are included. It costs more than the Lectric and Heybike folders it competes with; the torque sensor and Aventon's dealer network are what you are paying for.

Best for: RV and truck-bed storage · Riders who want smooth assist in a folder · Mixed gravel and pavement
