Bike Survival Kit: What to Carry on Every Ride to Fix Common Problems

Most problems that end a bike ride early are small: a flat tire, a loose bolt, a dropped chain or a light that dies at dusk. With a compact survival kit and a few basic skills, you can fix nearly all of them at the roadside and ride home instead of waiting for a lift. This guide covers what to carry, how to carry it and the simple checks that prevent many breakdowns in the first place.

The basic bike survival kit

These items fit in a small saddle bag or jersey pocket and cover the most common problems:

• Spare inner tube in the right size and valve type for your tires. Check the size printed on the tire sidewall.
• Tire levers, usually two or three, for getting the tire off the rim.
• Mini pump or CO2 inflator with a head that fits your valves (Presta or Schrader).
• Patch kit in case you get a second flat. Self-adhesive patches are quick; glue-on patches tend to hold better.
• Multi-tool with the hex keys and screwdriver bits your bike uses, ideally with a chain tool. A compact option such as the multi-tool covers most roadside adjustments.
• Tire boot, a small patch for the inside of a cut tire so the tube doesn’t bulge through. A folded piece of a sturdy wrapper can work in an emergency.
• Phone, ID and a way to pay for food or a ride home.

Extras for longer or remote rides

If you ride far from home, on gravel or on tours, add:

• A quick link (master link) that matches your chain, so you can rejoin a broken chain.
• A spare derailleur hanger for your frame, since a bent or snapped hanger can stop you completely.
• Zip ties and a little duct tape wrapped around your pump, for temporary fixes.
• A second tube and, if you run tubeless, a plug kit and a small bottle of sealant.
• Chain lube for long or wet rides.
• Extra food, water and a light layer, as fatigue and cold cause more trouble than mechanical faults on long days.

Our guide to items to carry for a cycling tour has a fuller packing list for multi-day trips, and gravel and adventure bikes covers kit for mixed-surface rides.

Don’t forget first aid

Minor crashes and blisters happen to everyone. A small first aid kit with adhesive bandages, gauze, antiseptic wipes, blister pads and a few pain relievers handles most scrapes until you get home. Ready-made kits such as the Cycle Medic bicycle first aid kit are designed to attach to a bike, which means it is always there when you need it. If you take medication or have allergies, carry what you need and a note with emergency contact details.

Lights, even on daytime rides

A ride can run later than planned, and weather can turn dark quickly, especially in autumn and winter. Small rechargeable lights weigh little and are worth carrying on every ride. A front light such as the Fenix BC15R Rechargeable Bicycle Light and a rear light like the Fenix BC05R V2.0 Tail Light mean you can still get home safely. For more on choosing lights, see our guide to bike lights.

How to carry your kit

• Saddle bag: keeps tools and a tube out of the way under your seat.
• Frame or top-tube bag: handy for snacks, phone and things you need often.
• Tool bottle: a container that fits in a bottle cage, useful if you have a spare cage.
• Jersey pockets or a small backpack: fine for short rides, but a bag on the bike keeps weight off your back.

Whichever you choose, pack the kit once and leave it on the bike, so you never set off without it. Check it every few months: patch glue dries out, tubes can get worn from rubbing and batteries need charging.

How to fix a flat on the road

1. Move somewhere safe, well off the road.
2. Release the brake if you have rim brakes, then remove the wheel.
3. Let out any remaining air and use tire levers to lift one side of the tire off the rim.
4. Pull out the tube and find the cause. Run your fingers carefully around the inside of the tire to find thorns, glass or wire, and remove it.
5. Put a little air in the new tube so it holds its shape, insert the valve and tuck the tube inside the tire.
6. Push the tire back onto the rim with your thumbs, working around toward the valve. Avoid using levers for this if you can, as they can pinch the tube.
7. Inflate to the pressure shown on the tire, check the tire is seated evenly, and refit the wheel and brake.

Our flat prevention tips cover how to reduce punctures in the first place.

A quick pre-ride check

Many roadside problems can be spotted before you leave. Before each ride, take a minute to check:

• Tires: pressure, and any cuts or embedded debris.
• Brakes: both levers firm, pads not worn down, wheels not rubbing.
• Quick releases and thru-axles: tight and closed properly.
• Chain: clean, lubed and running smoothly through the gears.
• Bolts: handlebar, stem and saddle secure.
• Lights and computer: charged.

If shifting is noisy or jumpy, our guide to adjusting a rear derailleur can help you sort it at home.

The home toolkit

At home, you can keep a fuller set of tools: a floor pump with a gauge, a full set of hex keys, a chain checker, cleaning brushes, degreaser and lube. A repair stand makes cleaning and adjusting much easier if you do regular maintenance. Learning a few basic jobs at home also means you’ll be more confident when something goes wrong on the road. For anything involving brakes or wheels that you’re unsure about, a local bike shop is the safest choice.

FAQ

What’s the most important thing in a bike repair kit?

For most riders, a spare tube, tire levers and a pump, because flat tires are by far the most common problem on the road.

Should I carry a spare tube if I ride tubeless?

Yes. A tubeless plug or sealant fixes most punctures, but a large cut may need a tube to get you home.

How often should I check my survival kit?

Every few months, and before any long ride. Make sure the tube is the right size, the patch glue hasn’t dried out and your lights are charged.
