The Home Bike Mechanic’s Setup: Fix Almost Anything on Your Bike
Most bike repairs are easier than they look — what they actually require is the right tool at the right moment. This is the map: organised by the problem you’re having, pointing you at the fix and the tool that makes it easy. Follow the links for step-by-step guides.
Punctures and tyres
Flats are the number-one roadside problem. The roadside fix is covered in our flat tyre guide; at home you’ll want proper tyre levers, a puncture kit and a floor-standing pump with a gauge (guessing pressure by thumb is how pinch punctures happen). Running tubeless? Stock sealant — it dries out — plus plugs for holes sealant can’t close and rim tape when you set wheels up.
Brakes
Squealing usually means contaminated or glazed pads — the full decision order is in our squeaky brakes guide. Keep spare pads for your caliper type; they’re a consumable, like brake pads on a car. Hydraulic brakes feeling spongy? That’s air in the line, and a bleed kit with mineral oil sorts it. Mechanical brakes gone sloppy? A fresh cable kit transforms them. For the persistent rub of a bent rotor, a rotor truing fork earns its keep.
Gears, chain and drivetrain
A slipping or jumping chain is one of three things — the diagnosis takes five minutes with our chain slipping guide. The single best-value tool here is the chain wear indicator: a new chain is cheap, a worn-chain-wrecked cassette is not. When replacement day comes, the Park chain tool (bundled with quick-link pliers) handles the chain, and the chain whip and lockring set unlocks the cassette. Keep the drivetrain clean with an X-3 chain machine, degreaser and the right lube for the season — wet for British winters, dry or wax for summer.
Wheels and hubs
A wobbly wheel is usually a few loose spokes: the spoke wrench fixes it in minutes, and a truing stand turns it into a precise, satisfying job. Rough or loose hubs on older or hub-motor wheels need cone spanners — a standard spanner is too thick and will round the locknuts.
Bottom bracket and cranks
Creaking from down below is usually the bottom bracket. External (Hollowtech-style) BBs need the dedicated tool; square-taper cranks come off with a crank puller — never a hammer.
Doing it right (and not breaking things)
Modern stems, bars and seatposts specify a torque number for a reason — over-tightening cracks carbon and strips threads. The Torq Stick covers the entire 4-20Nm range a bike uses. A T-handle hex set makes every other bolt a comfortable job, a proper cable cutter stops frayed ends, and carbon gripper paste ends slipping seatposts and creaking bars. For the work itself, a workstand is the upgrade your back will notice most, and the Muc-Off cleaning kit keeps winter salt from quietly eating the whole bike.
E-bike electrics
If your e-bike cuts out or loses power, work through the cut-out diagnosis guide — battery, connectors, sensors — with a multimeter before spending a penny at a shop. Converting a bike with a front hub motor? Fit a torque arm. Non-negotiable — it protects the fork from motor torque.
Start where your problem is
You don’t need everything on day one. Fix the problem you have, buy the tool it needed, and the box grows one repair at a time — which is exactly how every home mechanic’s kit got there.
