Lesson 1Common puncture causes and how to tell them apart: thorns, pinch flats, valve issues, bead problemsLearn to spot thorn punctures, pinch flats, valve failures, and bead issues from tube damage and situation. You will link each type to causes and pick fixes that stop repeat back wheel punctures.
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 back wheel removal and fitting back for okada-style bikesMaster safe, easy back wheel removal and fitting on city bikes. You will manage chain, gears, mudguards, and brakes while keeping frame, wires, and customer extras safe from damage.
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 steps and rider advice: road choices, tyre pressure checks, anti-puncture tape and linersGive clear advice fitted to each rider. You will cover road choices, pressure routines, protective tapes and liners, and real maintenance times that cut repeat punctures and build customer 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 4Eye and hand checks: tyre tread, sidewalls, valve, rim tape, and wheelLearn to carefully check tyre tread, sidewalls, valve spot, rim tape, and wheel build. You will mix eye checks with hand feeling to find hidden damage causing repeat back wheel punctures.
Reading tire tread wear and cut patternsSidewall cracks, bulges, and casing splitsValve base damage, leaks, and misalignmentRim tape coverage, holes, and displacementWheel trueness, dents, and spoke-related risksLesson 5Picking right tyre pressure: guide pressures, factors like rider weight, load, puncture protectionLearn to set back tyre pressure using maker guides, rider weight, load, roads, and puncture danger. You will balance comfort, grip, and flat protection, and note pressures for next visits.
Reading sidewall pressure ranges correctlyAdjusting for rider weight and cargo loadPressure choices for city, gravel, and rough roadsBalancing comfort, grip, and puncture riskRecording baseline pressures on service ticketLesson 6Tools and items for punctures: tyre levers, pump with gauge, spare tubes, patch kit, rim tape, tyre bootsBuild a full, quick puncture repair kit for shop and roadside use. You will choose and care for levers, pumps, tubes, patches, rim tape, boots, and extras that avoid delays on repeat jobs.
Choosing durable tire levers and sparesPump selection, gauges, and valve adaptersTube sizing, valve types, and storagePatch kits, glues, and instant patchesRim tape, tire boots, and emergency materialsLesson 7Repair choices and decision guides: patching vs new tube vs new tyreCompare patching, new tube, new tyre using safety, cost, strength guides. You will know when repair is ok, when to push better options for safety, and explain choices plainly.
Assessing tube damage and patchabilityEvaluating tire cuts, bulges, and exposed casingCost, reliability, and time trade-offsWhen to recommend full tire replacementExplaining choices clearly to the customerLesson 8First rider questions to know puncture story and pastPractice good questions to quickly know when, where, how punctures happen. You will note riding conditions, load, tyre age, past fixes to guide fast diagnosis of repeat back punctures.
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 9Tyre and tube choices for strength: puncture guards, tyre width, tube valve typePick tyres and tubes that cut repeat punctures while fitting bike and rider. You will compare puncture layers, widths, builds, valve types, and explain weight, ride feel, cost balances.
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 handing back: spin test, pressure check, quick-release/axle tightness, short test rideDo final safety checks before giving bike back. You will check bead fit, pressure hold, wheel straightness, axle tight, then short test ride or stand test for solid back puncture fix.
Spinning wheel to check wobble and rubConfirming even bead seating and no bulgesRechecking pressure after brief rest periodVerifying quick-release or thru-axle torqueShort test ride or stand test under loadLesson 11Wheel and rim checks: rim strip, spoke tips, sharp bits, rim brake wearCheck wheel and rim for hidden puncture causes. You will see rim strip cover, spoke ends, rough spots, dents, brake wear, then decide to file, replace, or suggest 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 12Step-by-step diagnosis: pump up, find leak, check tube and tyre insideFollow easy diagnosis steps: safe pump up, find leak spot, check tube and tyre inside. You will link leak place to causes and know when to keep hunting hidden sharp things.
