Getting skins on the bike frontier requires you to buy your desired skin and then equip it; here's how you can do it.
The Cycle Frontier – How to Equip Costumes/Character Skins!
Cycle frontier is a free-to-play, first-person extraction shooter where players gather resources on an abandoned alien world inhabited by monsters. Your mission is to fulfill a contract and get out of that planet.
You will enter a match with 19 players, fight your way to loot and get upgradeable items – craft and create equipment for yourself.
Crafting is one of the best ways to equip a gun. You have to explore a certain area and complete the materials needed to get a gun or loot it as a whole and equip it. With any gun, you will have the option to equip a shell to your chosen gun.
