Tire repair & sealant kit
A flat 10 miles from home is a long walk pushing a 60-lb e-bike. A small repair kit — plugs and sealant for tubeless, or a spare tube and levers for tubed tires — turns a ride-ending flat into a five-minute roadside fix.
How you fix a flat depends on your tires. If you run tubeless, liquid sealant inside the tire seals most small punctures automatically, and a plug kit (a rubber 'bacon strip' pushed into the hole with an insertion tool) handles bigger cuts without removing the wheel — the fastest roadside fix there is. Top up sealant every few months because it dries out, especially in warm climates.
If you run tubes (most budget e-bikes do), carry a spare tube, two tire levers and a way to inflate — a mini-pump or CO2. E-bike tires are wider and the wheels are heavier, so plan for it: a hand pump rated for the volume, or a couple of CO2 cartridges. Either way, the kit is small enough to live under your saddle permanently so it's there when you need it.

Pro tips from our test team
- Know which system you have before you ride — tubeless and tubed need different kits.
- A plug kit fixes most tubeless punctures without taking the wheel off — keep one in your bag.
- Sealant dries out; set a reminder to top it up a few times a year.
