E-Bike Parts: chargers, batteries, controllers, brakes, tires and more

Replacement parts are where mistakes get expensive. Each category explains how to identify what you have (voltage, connector, size, mount) before you buy. If your bike is misbehaving and you are not sure which part is at fault, start with an E-Bike Assessment instead of guessing.

Fenders

26x4 Fat Tire Fender Set, Front and Rear (generic)

Full-size fat e-bikes on 26x4 tires need fenders at least 4.5 inches wide, and the sets sold for them are wide alloy or plastic guards with adjustable stays and, usually, a bracket for a rack tail light. Universal sets fit most rigid and hardtail fat bikes with eyelets, but suspension forks and frames without eyelets need clamp-style stays or a model-specific set. Alloy fenders rattle less and survive better than plastic. Installation takes an hour the first time; take the time to set stays so the fender does not rub the tire under load.

Best for: 26x4 fat e-bikes ridden in rain or mud · Commuters who want full coverage rather than clip-on guards · Replacing worn or bent OEM fenders

Inner Tubes

26x4.0 Fat Tire Inner Tube, Schrader Valve (generic)

The 26x4 tube is the full-size fat-bike counterpart to the 20x4 folder tube, and it is what most 26-inch fat e-bikes run. Generic butyl tubes in 26 x 3.5–4.5 (or 4.0–4.9) are widely sold; the branded ones from Kenda, Sunlite and CST are not meaningfully different from house brands. Schrader is the common valve on these bikes. Because a 4-inch tube holds a lot of air at low pressure, pinch flats from running too soft are the usual cause of death, so check pressure weekly and carry a spare on long rides.

Best for: 26x4 fat-tire e-bikes · Spares for the trail bag or garage · Riders replacing a pinch-flatted tube

E-Bike Tires

CST BFT (Big Fat Tire) 26x4.0

CST's BFT (Big Fat Tire) is a widely fitted original-equipment tire on 26x4 fat e-bikes and one of the cheapest ways to replace a worn one. The tread is a medium-knob all-rounder: it handles hardpack, sand and snow acceptably and hums a bit on pavement, which is the normal deal with fat tires. Wire-bead versions are the common, inexpensive ones; folding versions exist at a higher price. If you spend most of your time on the road, a smoother fat tire will roll easier, but for mixed use the BFT is a sensible default.

Best for: Replacing stock tires on 26x4 fat-tire e-bikes · Mixed pavement and trail riding · Budget-minded riders

E-Bike Tires

Schwalbe Marathon Plus 700x38C

The Marathon Plus is the tire people buy when they are done fixing flats. Its thick SmartGuard belt is the reference for puncture resistance, and the 700x38C size fits most 700c commuter and hybrid e-bikes with room to spare. It is an e-bike-rated tire, heavy, stiff to mount, and not especially fast, but it shrugs off glass, wire and goathead thorns that would flatten a lighter tire. For a commuter who rides every day on city streets and does not want to think about tires, it is hard to argue with.

Best for: 700c commuter and hybrid e-bikes · Riders who get frequent flats from glass and thorns · Daily commuters who value reliability over speed

Inner Tubes

Sunlite Thorn Resistant Tube 700x35-43 Schrader

Thorn-resistant tubes are ordinary butyl tubes made with a much thicker casing, and Sunlite's are the ones bike shops have stocked for decades. The 700x35-43 Schrader size fits most 700c commuter and hybrid e-bikes. The thick wall stops the short thorns and wire that cause most commuter flats, at the cost of weight and a slightly dead ride feel. They pair well with a puncture-resistant tire for riders who refuse to fix flats on the roadside. If your rim is drilled for Presta, Sunlite sells the same tube with a Presta valve.

Best for: 700c commuter e-bikes in thorn and glass country · Riders who want belt-and-suspenders flat protection · Heavier riders who pinch-flat thin tubes
