Buying and unlocking bikes is part of the core loop
The official BikeLife Society experience says players earn cash through riding and tricks, buy or unlock bikes, and level up while they ride.
That is enough to make bikes an important progression choice, but it is not enough to name a current “best” bike. A useful comparison needs a dated roster plus the purchase cost, unlock condition, and an in-game performance distinction for every entry. Those details are not currently listed here.
So this hub is intentionally a source-watch page instead of a speculative price list. It helps you decide what to record while you play: the exact bike name shown in the game, its listed cash price or unlock condition, the date you saw it, and the page or official channel that supports it. That evidence can later turn into a transparent comparison without misleading new players.
