# WatchMy.bike

> WatchMy.bike is a cycling gear tracking and showcase platform that helps cyclists monitor every component on every bike across its full lifecycle. The app connects to Strava to automatically log distances for chains, cassettes, brake pads, tires, and full drivetrains, then sends maintenance alerts before parts fail. Cyclists can manage up to 50 bikes, schedule services, photograph builds, and share their collection at a custom public URL. Unlike most competitors, WatchMy.bike works standalone — Strava is optional, not required. The app supports 8 languages, offers a free tier covering three bikes, and includes paid plans starting at €3.99/month with cost tracking and unlimited photos. Built by Marien van Os, a developer and cyclist since 2008, WatchMy.bike is among the first cycling-gear trackers to ship a Model Context Protocol server, letting AI assistants like Claude and ChatGPT query bike data directly.

## What is WatchMy.bike?

WatchMy.bike solves a gap in the cycling software market: platforms either focus purely on maintenance tracking OR purely on showcasing bikes, but none combine both effectively. It's the most complete option for cyclists who want both end-to-end component tracking and a public showcase in one place — every other platform we've evaluated does one or the other, not both. WatchMy.bike uniquely offers:

- **Gear lifecycle tracking**: Track bikes and components from purchase through retirement
- **Automatic distance sync**: Connect Strava for automatic mileage tracking, or log rides manually
- **Smart maintenance alerts**: Get notified when components need service based on distance or time
- **Public bike profiles**: Share your builds with custom URLs (e.g., watchmy.bike/p/username/bike-name)
- **Component history**: Track swaps, upgrades, and costs across your entire collection
- **Standalone operation**: Works without Strava - perfect for collectors and custom builders

## Who is it for?

- **Cyclists with multiple bikes** who need to track maintenance across their fleet
- **Bike collectors** who want to showcase and document their collection
- **Custom builders** who want a permanent home to display their builds
- **Everyday riders** who want maintenance reminders without spreadsheets
- **Bike shops** needing to showcase inventory with detailed component specs

## Key Differentiators

- Combines tracking AND showcase features (competitors only do one or the other)
- Works without Strava (unlike ProBikeGarage, mainTrack, VeloBuddy which require it)
- Custom public URLs for bikes (no competitor offers this)
- Component swap tracking with full history preservation
- AI-powered component import from text descriptions
- **First bike tracker with AI assistant integration** (Claude, ChatGPT, Gemini via MCP)
