Bike maintenance apps compared: BikeCare, Strava, Garmin Connect, ProBikeGarage, mainTrack and Geer

Remaining life forecast per component (chain, tyres, brake pads, cassette)

BikeCare: BikeCare shows a remaining life in kilometres and days for chain, tyres, brake pads, cassette and 20+ further parts.

Strava: Strava counts the kilometres per component, but according to its help centre there is no target value to calculate against (retrieved 19 July 2026).

Garmin Connect: Garmin Connect compares the distance ridden against an interval that the user sets themselves; according to the Garmin forum that is the "Max Distance" input field.

ProBikeGarage: ProBikeGarage compares usage against service intervals that its catalogue presets and the user can adjust; a projected due date is not stated (as at 22 September 2026).

mainTrack: Maintenance is planned per part against a target the rider sets: "Plan your bikes maintenance periodically based on period of time, usage, rides or elapsed time", plus "Check your bike's parts usage since you last serviced them" and a notification "when a service is due". A wear-rate forecast with a projected date is not described in the provider's sources.

Geer: Geer runs components against service intervals you set: the homepage describes "Add your components, set maintenance intervals" and "Set suggested service intervals". Changelog v2.6.0 (9 June 2026) adds a switch of the progress display "between remaining and elapsed", and v2.11.2 shows a countdown per maintenance task. The parts named by the provider are chain, cassette, brake pads, tyres, brake rotors and bottom bracket.

Wear weighted by conditions (wet, surface, elevation gain)

BikeCare: In BikeCare, wet weather and surface feed into the remaining life of chain, cassette and chainrings, and elevation gain and wet weather into that of the brakes.

Strava: Strava tracks components in distance only.

Garmin Connect: For Garmin Connect (distance, hours, days and number of activities are documented), weighting by conditions is not stated on the provider's own pages.

ProBikeGarage: For ProBikeGarage (intervals by distance, moving time, elapsed time, number of rides and, on Premium, elevation gain are documented), weighting by conditions is not stated on the provider's own pages (as at 22 September 2026).

mainTrack: The provider itself lists the bases of its intervals as "period of time, usage, rides or elapsed time"; wet weather, surface and elevation appear neither there nor on any of the five pages of its website. Not stated on the provider's own pages.

Geer: On Geer's own roadmap board the request for brake wear weighted by metres descended and the request for weather-based chain wax intervals have both stood unchanged at "In Review" (the first since 18 April 2025, the second since 26 March 2026), while the provider demonstrably marks implemented requests as "Completed"; founder Roland Lehle put it in his own words on Product Hunt (around April 2026): "Right now we track distance and time intervals". What Geer does have is an include/exclude rule rather than a weighting: components can be marked as indoor, outdoor or both ("Ride types", changelog v1.11.0), with an extension to gravel and mountain-bike ride types listed as "Planned".

Wear weighted by the power actually put out

BikeCare: Chain, cassette and chainring are additionally weighted by the work done: 200 km out of the saddle uphill loads the drivetrain harder than 200 km rolling along the flat. The calculation runs on kilojoules per kilometre and only counts power actually MEASURED by a power meter; Strava's estimates are deliberately left out because they ignore wind and drafting. Without a power meter the calculation stays unchanged.

mainTrack: As usage figures the provider names only distance, hours, rides and time ("how many hours your race wheel have"). Watts, kilojoules or a power meter appear in neither the full App Store description (English and Portuguese) nor the website. Not stated on the provider's own pages.

Geer: Not stated on the provider's own pages. Neither the homepage, the help centre, the comparison pages nor the full changelog names watts, kilojoules, normalised power or power-meter data as a wear metric (checked 4 August 2026).

Tyre pressure calculator (front/rear width, tube/tubeless/hookless, ETRTO limit)

BikeCare: BikeCare derives the pressure from system weight, front and rear tyre width and the tyre system, and on hookless rims caps it hard at the ISO/ETRTO maximum.

Strava: Strava's component management has neither pressure nor width fields; a value could only be written into the free-text note.

Garmin Connect: A tyre pressure calculator is not stated on Garmin Connect's own pages.

ProBikeGarage: A tyre pressure calculator is not stated on ProBikeGarage's own pages.

mainTrack: Tyres appear in the provider's sources only as a part to be serviced ("when was the last time you replaced your tyres"), not as a calculator. Neither the home page, the support page nor the App Store description mentions tyre pressure, bar/psi, tubeless or hookless. Not stated on the provider's own pages.

Geer: Not stated on the provider's own pages (homepage, help centre, comparison pages, blog, changelog and feedback board, all checked 4 August 2026). The app itself sits behind a Strava login and cannot be checked from the outside.

AI assistant and AI bike setup

BikeCare: AI auto-setup creates the bike from make and model including its parts list (live web search), and the Copilot answers questions about your specific bike. Free of charge: the AI parts recommendation with checked shop links (40 requests a month) plus one AI bike setup and one Copilot question a month to try them out; Pro gives you more.

mainTrack: No provider source mentions AI or automatic bike recognition, and the description presents setup as manual ("Create Components ... Assign Components to Bikes"). The release notes for the current version 1.7.54 of 4 September 2026 (as at 22 September 2026) read only "Minor bug fixes and performance improvements." Not stated on the provider's own pages.

Geer: Not stated on the provider's own pages. The homepage feature list ("What's under the hood?": dashboard, push and mail notifications, easy swap, full history, private by design, ride types, any device), the help centre and the changelog name no AI or assistant feature; bikes are imported from Strava rather than created from make and model.

Chain care intervals per lubrication method (hot wax, drip wax, dry lube, wet lube)

BikeCare: BikeCare stores its own interval for each method.

Strava: For Strava, care intervals for bike components are not documented.

Garmin Connect: In Garmin Connect the chain as a "Bike Component" covers replacement, not recurring care.

ProBikeGarage: ProBikeGarage addresses chain waxing explicitly in a blog post of its own, but the intervals are set by the user ("based on the mileage or time intervals you set").

mainTrack: Intervals are freely definable ("Plan your bikes maintenance periodically based on period of time, usage, rides or elapsed time"), so a wax or oil interval can be set up by hand. Preset intervals that differ by lubrication method are not stated on any provider source.

Geer: Several care tasks per component are possible: changelog v2.3.0 (22 April 2026) states "Unlimited maintenance tasks per component – add as many service intervals as you need", and the request behind it, marked "Completed", argues precisely with "cleaning, waxing and replacing their chain", so you can set up a wax interval of your own. Preset intervals that differ by lubrication method (hot wax versus drip wax versus dry or wet lube) are not stated on the provider's own pages.

Cost analysis per year and per kilometre

BikeCare: BikeCare converts the recorded costs into a figure per year and per kilometre ridden, per bike and across all bikes.

Strava: Cost tracking for gear is not stated on the Strava pages we checked.

Garmin Connect: Cost tracking for gear is not stated on the Garmin Connect pages we checked.

ProBikeGarage: For ProBikeGarage, price comparison for spare parts and logging workshop visits are documented; a structured cost field with an analysis is not.

mainTrack: The provider's description names a service history, but neither cost fields nor an analysis per year or per kilometre, and the five pages of the website say nothing about costs. Outside the provider's own sources there are indications that workshop costs can be recorded, but that cannot be evidenced from the provider's own statements. Not stated on the provider's own pages.

Geer: Not stated on the provider's own pages. The homepage carries a savings widget ("Calculate your savings", footnote "Based on average component prices and recommended replacement intervals"), which works from average prices rather than your own records; recording your own costs per part and analysing them per year or per kilometre is not stated.

Service book with costs and warranty, export as CSV and PDF

BikeCare: BikeCare exports your recorded entries as CSV and each bike's service record as a PDF.

Strava: Strava offers only master data and a free-text note per component.

Garmin Connect: Garmin Connect allows a full account data export with CSV and JSON, but no service book with maintenance entries.

ProBikeGarage: ProBikeGarage keeps a documented maintenance history with attachments of up to 10 GB on the Premium subscription; a CSV or PDF export is not stated.

mainTrack: The service log itself is clearly documented: "record all serviced parts and components" and "Keep track of all services, so you know when you last serviced a part or component." Cost fields, warranty details and an export as CSV or PDF are not stated on any provider source.

Geer: The service history itself is documented: the homepage says "Full History – Detailed maintenance history at a glance for every single part you own", and all three of Geer's own comparison pages tick "Service history". The export is missing: "Data Export (CSV, Excel, ...)" has sat unresolved at "In Review" since 6 February 2026, and a PDF export as well as cost and warranty fields in the service history are not stated on the provider's own pages.

Push and email reminders with separately adjustable frequency

BikeCare: In BikeCare the push frequency and the email digest are configurable independently of each other, and reminders can be snoozed individually.

Strava: Reminders for bike components are not stated on the Strava help pages we checked; a distance email is documented explicitly for running shoes.

Garmin Connect: Garmin warns as you approach the maximum distance you set yourself; the delivery channel is not specified in the sources.

ProBikeGarage: For ProBikeGarage, maintenance alerts with an early warning at 10 % remaining are documented, and since February 2025 alerts can be snoozed for a bike, a component or a single interval; email reminders and an adjustable sending frequency are not stated (as at 22 September 2026).

mainTrack: Push is documented: "Receive timely notifications upon completing a ride or when a service is due." Email reminders and separately adjustable intervals are not stated anywhere; the only email function on the website is a newsletter list (page "subscription-confirmation").

Geer: Both channels are documented and the provider highlights them itself: the homepage lists "Push & Mail Notifications – Friendly reminders when components are due", and Geer's own comparison page against mainTrack says "Geer sends both push notifications and email alerts when components are due for service." A separately adjustable interval for push versus email is not stated anywhere; the help centre only covers enabling notifications in the browser, and the changelog names "Bundle email notifications" (v1.9.0) plus a fix against repetitive notifications (v1.9.2).

Friend comparison, challenges and leaderboard

BikeCare: In BikeCare this is voluntary and switched off by default. Private groups with their own challenges are available.

Strava: Strava is unbeaten here: segments, kudos and public clubs with a feed are something we deliberately do not rebuild.

mainTrack: Neither the full App Store description nor the website shows a social, challenge or leaderboard function. The provider places the social side expressly outside the app, in a Strava club ("Join our mainTrack.app club and share your rides.", 947 members on 22 September 2026). Whether there are in-app leaderboards is not stated on the provider's own pages.

Geer: Not stated on the provider's own pages. What the pages do describe is a referral programme ("For every friend you refer to Geer, you get 1 month of Pro for free", help centre; changelog v1.15.0) and a Strava club as an external community; a comparison with friends, challenges or a leaderboard are not stated.

Where the rides come from (sync sources)

BikeCare: This is where BikeCare is weakest: it syncs via Strava only, by webhook shortly after the upload. Without a Strava account there is no automatic import.

Strava: Strava records rides itself and takes them in from Garmin, Wahoo, Apple Watch and Fitbit.

Garmin Connect: Garmin Connect gets the activities straight from its own device, but is tied to Garmin hardware for that; an automatic import from Strava into Garmin Connect does not exist.

ProBikeGarage: In its primary sources, ProBikeGarage likewise names Strava as its only sync source.

mainTrack: Exactly two routes are documented: "Keep track of your bikes and components usage by connecting to Strava or manually recording activities." Garmin, Wahoo, Komoot or further sources are not stated on any provider source; apart from Strava, no third-party service is named anywhere on the website.

Geer: Strava only, and deeply so: the help centre says "Geer receives your new rides from Strava the moment they happen" (webhook in real time, plus a daily full sync at 6 p.m. and a manual sync in the settings), bikes are imported from Strava, and "Your data is securely linked to your Strava account". Garmin and Wahoo are not stated as sources ("Integration of Wahoo and Garmin APIs", with 12 votes, is among the highest-voted open requests on the feedback board and has been at "In Review" since 17 May 2025), and adding bikes manually without Strava has been an open request there since 31 May 2025. A Strava account is therefore a prerequisite; a paid Strava subscription is expressly not.

Operating hours as an interval metric of its own (suspension fork, shock)

BikeCare: For fork and shock, operating hours are the technically correct yardstick: Fox and RockShox publish their service intervals in exactly that unit. BikeCare keeps them as a metric of its own alongside kilometres and calendar time, preset to 50 h for fork and shock and 100 h for the dropper post.

Strava: For Strava, elevation gain and hours as a unit of measure for components are an open request in the Community Hub.

Garmin Connect: Alongside distance, Garmin also records hours and days.

ProBikeGarage: ProBikeGarage works with moving time and elapsed time.

mainTrack: Hours are demonstrably kept as a usage figure in their own right ("how many hours your race wheel have"), and the provider names suspension expressly as a use case ("Or when you need to service your suspension?"). Whether an interval can be set directly in operating hours is not clear from the provider's sources; the interval bases named there are "period of time, usage, rides or elapsed time".

Geer: Alongside distance, Geer knows time-based maintenance tasks: changelog v1.9.1 (30 June 2025) refers to "moving time and timer maintenance tasks" (that is, tasks running on ridden moving time as well as on calendar time), and v1.10.3 adds "Timer service notifications". Suspension forks and shocks are not named as component types on the provider's own pages; the parts advertised are chain, cassette, brake pads, tyres, brake rotors and bottom bracket, with components freely creatable ("Chain, cassette, brake pads – whatever").

EU provider under the GDPR, public legal notice

BikeCare: BikeCare is a sole trader based in Germany, and the legal notice gives a postal address. Uploaded document files are stored in the EU; hosting and database run on Cloudflare, and some features, such as the AI, also process data in the USA; the privacy policy has the details.

Strava: Strava, Inc. is based in San Francisco; for EU users Strava Ireland Limited is responsible, and according to the privacy policy the processing takes place in the USA on the basis of standard contractual clauses.

Garmin Connect: Garmin is a US group with a Swiss holding company and a German entity in Würzburg; the server location could not be evidenced on 19 July 2026.

ProBikeGarage: According to the App Store, the seller of ProBikeGarage is Tappr Labs LLC, a US legal entity with no stated server location.

mainTrack: GDPR rights are named in the privacy policy (withdrawal of consent, erasure, portability "in a structured, commonly used and machine readable format", objection). There is no legal notice, no controller with a postal address and no server location; on transfers it says only that "data transfers may involve transferring and storing your information in a country other than your own". The German App Store notes expressly that the developer has not identified itself as a trader for this app.

Geer: Fully disclosed: the footer of every page carries "GEER BIKE OÜ · Reg. 17213697 (Äriregister) · Pärnu mnt 139b, 11317 Tallinn" together with a contact address, so the company is registered in Estonia with its commercial register number. The privacy policy names "renewable-powered servers in Germany" as the server location, states "EU-Based & GDPR-Compliant" with the legal bases Art. 6(1)(a), 6(1)(b) and 6(1)(f) GDPR, lists the processors by name (Mailgun, Plausible, Sentry, Grafana, Stripe, Strava, Meta Platforms) and discloses third-country transfers under standard contractual clauses; the applicable law is Estonian.
