The Problem
A city stuck in low gear
Bike repair in Berlin is a frustrating experience. We identified three core issues that our platform aims to solve.
😩
Shops Are Overwhelmed
Especially in spring and summer, getting a simple fix can mean long waits and high costs.
🔧
Small Fixes, Big Hassle
A flat tire or brake adjustment shouldn't require a full-scale shop visit and the associated overhead.
🫶
Emotional connection
Berlin has countless bike-savvy hobbyists with no easy way to offer their skills for a small side income.
The Solution
Connecting the Community
Our solution is a peer-to-peer platform for on-demand bike repairs.
We designed it for two key user groups.
Think: Wolt meets Nebenjob meets community mechanic.
