Lesson 1Common flat causes and how to distinguish them: puncture, pinch, valve failure, bead separationLearn to tell apart puncture, pinch, valve, and bead issues by looking at tube damage and situation. You'll link each type to main causes and pick fixes that stop rear flats coming back.
Single-hole punctures from sharp objectsSnakebite pinch flats and low pressure linksValve stem tears, leaks, and core failuresBead seating issues and blowout signsCombining tube clues with rider historyLesson 2Step-by-step rear wheel removal and reinstallation for city bikesGet good at safely taking off and putting back rear wheels on town bikes. You'll manage chain, gears, mudguards, and brakes while keeping the frame, wires, and rider's extras safe from harm.
Preparing bike, stand, and gear positionDisconnecting brakes and hub gear linkagesSafe chain and derailleur handlingCorrect axle placement in dropoutsAligning fenders and racks after refitLesson 3Preventive measures and customer advice: route choices, pressure checks, puncture-resistant tape and linersGive clear tips to suit each rider. You'll talk about paths to take, tyre pressure checks, tough tapes and liners, and real upkeep times that cut down repeat flats and earn rider trust.
Advising on debris-heavy and clean route optionsTeaching simple weekly pressure checksUsing puncture-resistant tape and linersSetting realistic tire inspection intervalsExplaining trade-offs of extra puncture protectionLesson 4Visual and hands-on checks: tire, sidewall, valve, rim tape, and wheelLearn to check tyre tread, sides, valve spot, rim tape, and wheel build step by step. You'll mix looking and feeling to find hidden damage and patterns causing repeat rear flats.

You'll balance ride comfort, grip, and flat protection, noting down advice for next time.

You'll choose and care for levers, pumps, tubes, patches, rim tape, boots, and extras that avoid hold-ups on repeat flats.

You'll know when repair works, when to suggest better for safety, and how to explain choices openly.

You'll note riding setup, load, tyre age, and past fixes to guide quick checks for repeat rear flats.
Opening questions about ride type and terrainClarifying when and how the flat appearedChecking tire age, mileage, and storageReviewing previous flat repairs and failuresRecording answers in clear service notesLesson 9Tire and tube selection for durability: puncture protection, tire width, tube valve typePick tyres and tubes to cut repeat flats while fitting bike and rider. You'll check puncture layers, widths, builds, and valve types, explaining weight, ride feel, and cost choices.
Comparing puncture protection layers and beltsChoosing tire width for load and comfortTube sizing and wall thickness choicesSchrader vs Presta vs Dunlop valve selectionMatching components to rim and frame clearanceLesson 10Safety checks before return: spin test, inflation check, quick-release/thru-axle security, short test rideDo last safety checks before giving bike back. You'll check tyre seating, pressure hold, wheel straightness, and axle tightness, then do a quick ride or stand test for solid rear flat fix.

You'll look at rim tape cover, spoke tips, rough spots, dents, and brake wear, deciding on filing, parts swap, or wheel rebuild.
Checking rim strip width and alignmentIdentifying sharp or protruding spoke endsFinding burrs, dents, and pinch pointsAssessing rim brake track wear and cracksDeciding on repair, replacement, or rebuildLesson 12Sequential diagnostic steps: inflate, locate leak, inspect tube and tire interiorFollow steady check steps: safe pump-up, find leak spot, and look inside tube and tyre. You'll link leak place to causes and know when to keep hunting sharp bits.
