Geer

Your bike's check engine light powered by Strava

2026-03-31

Product Introduction

  1. Definition: Geer is a specialized Progressive Web App (PWA) designed for bicycle component lifecycle management and predictive maintenance tracking. It functions as a cloud-based service-interval engine that monitors the precise wear and tear of individual bike parts—such as drivetrains, braking systems, and bearings—by synchronizing real-time ride data via the Strava API.

  2. Core Value Proposition: Geer serves as a "check engine light" for cyclists, eliminating the guesswork involved in manual maintenance logs. By providing automated, distance-based alerts, the platform prevents mechanical failures before they occur. This proactive approach optimizes drivetrain efficiency, extends the lifespan of expensive components like cassettes and chainrings, and significantly reduces the total cost of ownership for high-performance bicycles.

Main Features

  1. Automated Strava Synchronization: Geer utilizes the Strava API to automatically import ride data, mileage, and elevation stats. Once a user connects their account, the platform identifies specific bikes used for each activity and updates the accumulated distance for every component attached to that profile, removing the need for manual data entry.

  2. Granular Component Lifecycle Tracking: Users can add specific parts to their virtual garage, including chains, cassettes, brake pads, tires, rotors, and bottom brackets. Each part is tracked individually with customizable service intervals. The system allows for "Easy Swaps," enabling users to move components between different bike profiles while maintaining a continuous wear history.

  3. Cross-Platform Progressive Web App (PWA) Architecture: Built as a PWA, Geer bypasses the limitations of traditional app stores. It offers a native-like experience on iOS, Android, and desktop browsers without requiring a download from the Apple App Store or Google Play. This ensures universal compatibility, offline capabilities, and instant updates across all devices.

  4. Predictive Maintenance Alert System: The platform features a color-coded dashboard that provides a bird's-eye view of component health. When a part reaches its pre-set distance threshold, Geer triggers push notifications and email alerts. These reminders are designed to reach the user before "riding to failure" occurs, preventing the "cascading wear" effect where a stretched chain destroys a cassette.

  5. Indoor vs. Outdoor Wear Logic: Recognizing that indoor trainer miles affect components differently than outdoor miles (especially concerning drivetrain grit and tire wear), Geer allows users to categorize rides. This ensures that maintenance intervals accurately reflect the environmental conditions of the ride.

Problems Solved

  1. Pain Point: Expensive "Neglect" Repairs: Most cyclists only replace parts once they fail or cause shifting issues. By then, a $40 worn chain has often damaged a $300 cassette. Geer solves this by enforcing timely replacements, saving users an average of €85 per year per bike by preventing unnecessary secondary component damage.

  2. Target Audience:

    • High-Mileage Road and Gravel Cyclists: Riders who accumulate 5,000km+ annually and need to manage frequent drivetrain maintenance.
    • Multi-Bike Owners (N+1 Enthusiasts): Users who juggle several bikes and lose track of which chain was replaced when.
    • Performance-Oriented Riders: Cyclists who want to ensure maximum mechanical efficiency and safety during races or long-distance events.
    • Mechanic-Averse Users: Individuals who prefer riding over wrenching and need a simple, automated reminder system to keep their gear safe.
  3. Use Cases:

    • Drivetrain Longevity: Tracking 0.5% and 0.75% chain stretch intervals to protect the cassette.
    • Hydraulic Brake Safety: Monitoring brake pad thickness based on mileage to prevent rotor scoring and braking failure.
    • Fleet Management: Managing maintenance schedules for a household with multiple riders and various bike types (MTB, Road, E-bike).

Unique Advantages

  1. Differentiation from Strava & Competitors: While Strava includes basic gear tracking, it is primarily desktop-only, lacks proactive push notifications, and does not suggest maintenance intervals. Unlike competitors like ProBikeGarage or MainTrack, Geer is built in the EU with a "privacy-first" philosophy, is entirely user-funded (no venture capital or ads), and focuses on a lightweight PWA interface rather than a bloated native app.

  2. Key Innovation: The Financial Impact Model: Geer integrates a "cost of neglect" calculator that uses real-world component pricing and replacement intervals to demonstrate the ROI of the subscription. It transforms maintenance from a chore into a verifiable financial saving.

Frequently Asked Questions (FAQ)

  1. Do I need a Strava Premium (Summit) subscription to use Geer? No. Geer works with the free version of Strava. It pulls activity data through the standard API, so any cyclist with a basic Strava account can automate their component tracking.

  2. Why can’t I find Geer in the Apple App Store or Google Play Store? Geer is a Progressive Web App (PWA). This technology allows you to "Add to Home Screen" directly from your browser (Safari or Chrome), providing a full-screen, app-like experience without the privacy concerns or overhead of traditional app stores.

  3. How does Geer help me save money on bike repairs? By notifying you to replace your chain at the optimal time, Geer prevents the chain from "stretching" and grinding down the teeth on your cassette and chainrings. Replacing three chains is significantly cheaper than replacing one full drivetrain, which is the primary source of savings for Geer users.

  4. Is my cycling data private? Yes. Geer is EU-based and compliant with strict privacy standards. Unlike many free apps, Geer does not sell user data to advertisers; the platform is funded entirely by Pro subscriptions, ensuring that the user, not the advertiser, is the priority.### Product Introduction
