Extreme Bicycle

Extreme Bicycle puts you in the saddle of a high-performance machine built from parts you actually earn. The synthesis system lets you combine collected components into something genuinely your own — not just a cosmetic swap, but a bike that behaves differently depending on what you've built.

Racing across varied terrain reveals just how much your choices matter. Loose dirt, sharp bends, elevation drops — the track doesn't forgive poorly assembled builds. There's a real satisfaction in watching a well-crafted bicycle hold its line where others wobble.

Competition sharpens everything. Chasing down global leaderboard times or going head-to-head against other riders adds pressure that solo runs simply can't replicate. The gap between a good run and a great one usually comes down to knowing your build's limits — and pushing just past them.
