PitArena — online shop

With spare parts, a product list is not enough. The customer needs certainty that a part fits their model and year — otherwise they buy blind and send it back. A catalogue running into thousands of items had to stay navigable instead of turning into an endless list.

I built an online shop with a catalogue of bikes and parts. Parts are sorted by model (LITE 125, PILOT 125, Factory 190) and by group — brakes, engines, suspension, electrics. Plus filtering by model and year, a cart and customer account, favourites and product comparison.

The shop now offers 4,551 products in 695 categories, with the spare-parts catalogue broken down across 19 YCF motorcycle models — the customer clicks their model and sees only parts that fit. Even at that scale it holds 99/100 in Lighthouse Performance on desktop, with the main content rendering in under 0.9 s (measured with local Lighthouse 13.4.1 on 16 September 2026). In its first two and a half months (1 July – 17 September 2026) it handled 116 orders worth CZK 468,202 in total, averaging CZK 4,036 per order (figures from the shop administration).
