How to Unlock Motorcycles in Steal An Egg On KuKirin

Motorcycles in Steal An Egg On KuKirin unlock with money. Better Kukirins are sold in the in-game shop for cash, that cash comes from your pets, and the new bike is yours to ride the moment you pay. In the clearest recorded purchase, the next better Kukirin was priced at 400,000 cash — "Okay, 400,000, I need 400,000?" — and right after paying, the player was off on it: "And now we have a Kukirin. Only it's blue."

The game's own How to Play puts these unlocks at the same spot in the loop: ride KuKirin to steal eggs, hatch eggs to collect rare pets, "💰 Earn money from your pets", "⬆️ Upgrade your speed", then "🔓 Unlock faster motorcycles and rarer eggs". Pet income is the fuel, and the shop is where the unlock actually happens.

Where motorcycles are unlocked: the shop

You start on a basic Kukirin — the players in one recorded session guessed their starters were "G2" grade — and every upgrade lives in the shop. Asked where better bikes come from, the answer was blunt: "but you can buy better ones. >> Where? >> In the shop." Walk up, read the cash price on each Kukirin, and you know exactly what the next tier asks of you. In that session, nothing besides money ever gated a purchase.

How to unlock your next motorcycle

1. Earn cash from pets. Pets pay out continuously, even weak ones — a freshly hatched pet earned "60 per second" — and better pets earn far more: one Velicoraptor "earns 11,000", and later "the bull earns me 11,000." That's the spine of the money-making loop, and the codes page collects anything currently active.
2. Hatch more pets to compound the income. Every egg you steal or buy can hatch into another earner, and each new pet boosts you directly: "When you get a new pet, it gives you speed and cash." Steal eggs (how to steal eggs), hatch them (how to hatch eggs), and let the snowball roll. The top player in that session credited the free route: "I collected a lot of animals for the index."
3. Open the shop and read the next Kukirin's price. The verified next-step bike cost 400,000 cash, and the player funded it purely by playing — turning down a Robux cash-multiplier shortcut with "400,000 is easy."
4. Buy it and ride away. The purchase is instant, and success is unmistakable: you immediately own the new bike and can ride it. No waiting, no extra step.
5. Repeat for each faster tier. The same pet-cash route paid for every successive bike in that session, from the 400,000 blue Kukirin up to a top model costing millions.

One caveat before you start saving: cash was the only requirement ever shown. No purchase in the session was refused over a too-low speed stat, but one recorded session can't rule out extra checks at higher tiers — treat money as the confirmed gate.

What the bikes cost (as observed)

Prices come from a single auto-captioned gameplay session, so read them as observed figures rather than an official price list — the 400,000 blue bike is the only purchase shown start to finish.

Grades mark the tiers along the way: the session's riders started on "G2" bikes while a rival already had "an orange G4." This isn't the complete roster — the motorcycles list covers the models themselves in detail.

The one Robux vehicle: Thunderwing Kukirin

Exactly one motorcycle skips the pet-cash route: the Thunderwing Kukirin, sold as a gamepass for R$ 99. It's the only bike in the game's gamepass list.

Everything else on that list is a multiplier, not a vehicle. The 2x–32x Speed passes and the x2 Money / x2 Growth passes boost your stats and income, but buying them doesn't unlock a motorcycle.

What a new bike gets you

The session's verdict on the top model says it all: "And it earns more. Ooh, and has more speed." Higher tiers pay better and move faster, though the game didn't show exact per-bike numbers. Officially, these unlocks sit right after the speed upgrade stage of the loop and open the way to "rarer eggs" — and if you're choosing a target, the fastest motorcycles page ranks the lineup.
