05 / THE LAB — INDEPENDENT CONCEPT/SPEICHE (Independent Concept)/2026

SPEICHE

Resilient job scheduling and operational clarity for bicycle workshops.

An independent high-density specialist ERP application featuring client-side state: Order intake, parts inventory, mechanic time tracking, and workshop scheduling with responsive local state management.

SPEICHE Workshop Manager — Operational dashboard for bicycle repair shops
High-density operational dashboard featuring job status pipeline, scheduling, and live inventory.
02 / OPERATIONAL CONTROL: WORK-ORDER PIPELINE

State-machine driven repair workflows without paper chaos.

Replacing lost paper handlebar tags with a resilient digital repair board.

During peak season rush, handwritten paper tags cause lost parts and delayed handovers. SPEICHE routes every job through a deterministic state machine: Intake, live stopwatch tracking, parts reservation, and sign-off checklists operate in one unified interface.

SPEICHE Work-order board with status filtering and active mechanics

Deterministic state management across all active service tickets with priority and parts indicators.

03 / PARTS INVENTORY & STOCK

Resilient inventory control: Critical wear parts tracked in real time.

Tubes, chains, and cassettes are reserved upon job kickoff. When stock falls below safety thresholds, re-orders are visually flagged.

📦

Automated Reservation

Components are earmarked upon diagnosis, locking physical stock from being reassigned to other jobs.

⚠️

Safety Stock Alerts

Color-coded stock thresholds highlight impending shortages before inventory runs out, generating supplier POs.

🔍

Barcode & Bin Tracking

Unambiguous shelf indexing (e.g. Bin B-04) and barcode scanning for rapid location on workshop racks.

Parts inventory (/lager): Visual threshold alerts when essential cassettes, chains, or pads run low.

04 / AT THE REPAIR STAND: TOUCH ERGONOMICS

High-contrast touch targets engineered for the workshop floor.

Triggering timers, claiming parts, and signing off checklists without keyboards: Calibrated for greasy fingers and stand-mounted tablets.

05 / OUTCOME & THE LAB

Specialist software built as a genuine craftsman's tool.

SPEICHE demonstrates how modern web standards can alleviate operational strain in physical repair shops: Bypassing bloated SaaS to deliver an instant, resilient tool that lets mechanics focus on their craft.
