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.

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

Slime Smart Tube 26x1.75-2.125 Schrader (Self-Sealing)

Slime's pre-filled Smart Tube is the lazy rider's best friend: a standard butyl tube with sealant already inside, so small punctures from thorns and wire seal themselves as you ride. The 26x1.75-2.125 Schrader version fits the typical 26-inch tire on many older-style and budget e-bikes, and Slime sells the same thing in 20, 24, 27.5 and 700c sizes. It will not stop a pinch flat or a large cut, and the added weight is noticeable, but for a commuter who rides through debris it can mean months without a flat.

Best for: 26-inch e-bikes with 1.75–2.125 tires · Commuters plagued by small punctures · Riders who do not want to carry a patch kit

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
