About us
Built by people who ship
bikeryOS is made by BrettlJausn, a small, product-minded studio. We hold ourselves to the same bar we set for the shops we serve: real software in production, hosted in the EU, built to be audited and to last.
Why we build bikeryOS
Bike retail in the DACH region runs on a patchwork of ageing till systems, spreadsheets and disconnected tools. Stock, workshop, sales and the customer never share one memory — so the same data gets re-keyed a dozen times a day and the shop still can’t answer a simple question.
bikeryOS is one connected system for the whole shop: inventory, point of sale, workshop planning, purchasing over VeloConnect and BIDEX, RKSV and TSE fiscal, a customer portal and AI woven through it all. One shared memory, from the first enquiry to the tenth service.
What we hold ourselves to
// 01 · Production
Real software, in production
Everything we build we run ourselves. No slideware, no vaporware — a live demo you can open without signing up.
// 02 · EU
Hosted in the EU
Your data stays in the EU, with fiscal compliance for Austria (RKSV) and Germany (TSE) built in, not bolted on.
// 03 · Longevity
Built to last
Auditable, multi-tenant and multi-language from day one — designed for shops that plan to be around for decades.

The founder
Karl Friesenbichler
Founder · BrettlJausn
Karl founded BrettlJausn after two decades bridging strategy, technology and execution — from Tier-1 robotics and automation primes to a €50–100M regional P&L as CEO Asia Pacific of a global automation group, and a warehouse-software platform he built and sold. He brings that operator’s view to bikeryOS: software that has to work on a busy shop floor, not just in a demo.
