The originally summoned bicycles are all at Level 0.
You need to use a certain amount of CYC to level up your Bicycles. The higher level your Bicycles are, the more CYC you would need to level up next.
You could earn CYC through Riding Jobs, SOLO Race, Team Race, PvE, etc. The Level is one of the most important attributes a bicycle has, so it will directly increase your power and working efficiency, but it will not increase your basic data. A high-level mining task needs bicycles with a compatible level.
When you up the level of Bicycles then the upper limit of CYC will be increased so that you can earn more per day. Also when you will reach level 20, you will earn BCF.
Upon level-up, users will attain 2 - 12 additional Attribute points to assign according to their bicycle quality.
Additional perks will be unlocked upon reaching certain level milestones:
At level 20, the user needs to choose between earning CYC or BCF. Switching between CYC/BCF earning is allowed, but will be subject to a cooldown duration.
