Patch kits, tire levers, plugs and CO2 for roadside fixes.
Flats on an e-bike are more annoying than on a pedal bike for a simple reason: the bike is heavy, the rear wheel often has a motor with a cable attached, and walking 60 pounds home in Texas heat is miserable. A small, well-chosen repair kit turns a bad afternoon into a ten-minute stop. The kit should match your tire system, your bike, and how far you typically ride from a pickup.
For tubed tires, which is still most e-bikes, the core kit is tire levers, a patch kit or a spare tube, and a way to inflate. Glueless patches are quick and fine for getting home; vulcanizing patches with glue last longer. Given how hard it is to pull a rear hub-motor wheel at the roadside, many riders now carry a tube sealant injected through the valve or run sealant pre-loaded in their tubes, which seals most thorn punctures without removing the wheel. Frisco's goathead thorns and construction debris make sealant especially sensible.
For tubeless setups, a plug kit with bacon-strip plugs and an insertion tool handles most punctures from the outside in seconds; patches are for the rare inside-out repair. Either way, pair the kit with a pump or inflator sized for your tires, and learn the process at home once, with the bike on a stand, before you need it at the side of the Cottonwood Creek trail. If a flat keeps coming back, the cause is usually inside the tire or on the rim, and our troubleshooting guide on recurring flats walks through the checks.
