The brief

Find out within eight weeks whether there is a market for a retrofittable e-bike battery system. Not market research — real orders.

Approach

We applied the MVP method we later distilled from this project. One core scene (configurator + checkout), everything else after validation.

Tech choices

  • Shopify as headless backend instead of building checkout — time-to-market beats elegance
  • Astro as storefront — editorial feel with full SEO control
  • Sanity for product storytelling, blog, cases
  • Cloudflare Pages for global CDN and EU compliance

What we learned

The biggest learning was about the audience. We had assumed private customers — the first 50 orders came from delivery services. Pure market research would not have caught this. It defined our entire B2B track.
