Start with the right experience
The official Roblox listing is Kukirin Life [Testing], published by Mukbang Lovers. Join from that listing and open My Rides to check for the free G2 starter scooter. The game is playable immediately; available footage does not show a required tutorial.
Take a short ride before spending currency. Try the confirmed wheelie inputs, look for the orange event circle and inspect the menus for quests. These first checks reveal the core loop without committing cash or Robux.
