Bike Repair & Maintenance Log

Bike repair guides and a maintenance log in one app: find what's wrong, fix it step by step, and see which parts of each bike are due for service. ▶ STEP-BY-STEP REPAIR GUIDES • 30 guides, from fixing a flat and plugging a tubeless tire to chain wear, gear indexing, brake pads, disc rub and saddle height. • Each guide tells you about how long it takes, how hard it is and which tools you'll need. • One step at a time, each with its own drawing. The screen stays on while a guide is open. • Tap a part on the bike drawing (wheels, chain and gears, brakes, bar and stem, saddle, cranks and pedals, e-bike battery) to see its guides. ▶ WHAT'S WRONG? • Pick what you hear or feel: a creak when pedaling, gears that skip, brakes that squeal or feel spongy, a wheel that wobbles, frequent flats and more (15 symptoms). • See the likely causes, most common first, each with the guide that checks it. • Causes that affect safety say so clearly: don't ride until it's fixed. ▶ A SERVICE TRACKER FOR EVERY BIKE • Add your bikes with type, wheel size and gears. • Add rides or an odometer reading to keep each bike's distance and riding time up to date. • Track wear on the chain, cassette, brake pads, rotors, tires, sealant, cables, fork, shock, bearings and more. • Set each interval by distance, months or riding hours, whichever comes first, using the value from the part's manual. • See Due, Due soon and OK at a glance with what's left or over, plus one list of everything due across all your bikes. • Mark a service done with the date, distance, a note and a photo. The interval restarts from there and the history stays with the bike. • Optional reminder on the morning a month-based interval is due. ▶ WORKSHOP CALCULATORS • Tire pressure starting estimate from the load on each wheel, for tires from 23 to 37 mm, never above the tire or rim maximum you enter. • Gearing: ratio, development, gain ratio, gear inches and speed at your cadence. • Chain length in links for 2× and 3× derailleur bikes, with the big-big cross-check. • Spoke length for conventional J-bend wheels. • Saddle height first estimate with the 109% inseam method. ▶ YOUR RECORDS • Kilometers or miles. • Backup files with your bikes, history and photos, and a restore that shows what will be added or updated before anything changes. • Export the service history as a CSV file. • Deleted entries stay in Trash for 30 days, with Undo right away. ▶ GOOD TO KNOW • The guides are general guidance written by the Bike Fix team. Your component maker's instructions always come first, and safety jobs tell you when to stop and see a mechanic. • No torque figures are guessed: use the value printed on the part or in its manual. • Hydraulic brake bleeding is explained as an overview only. • Distance is what you enter. The app does not record rides with GPS or import them. • There are no built-in service intervals; you enter the ones from your parts' manuals. • Calculator results are estimates and theoretical values, not measurements. • No account, no sign-in. Your bikes and history are stored on your phone. The camera is used only when you take a service photo. • Ads appear on list screens, and sometimes after you finish a guide or save a service, never in the middle of a guide.

A bike with no wear items yet now shows “Plan this bike's maintenance” on its “Wear” tab: typical check intervals in months for common parts, each one editable (your part's manual comes first). Turn on “Remind me on the date a part is due” for one notification on the morning a part is due; permission is asked, if needed, only after “Save plan”. Reminders for a bike without a name now show its bike type instead of empty brackets.
