# BIKE RARITY

There are such classes of bikes: Common, Uncommon, Rare, Epic, and Legend.

## **Increase a bike rarity.**&#x20;

To progress to the Uncommon level, players must reach level 17 with a bike in the Common class and have all the items for that class installed.

Likewise, with other classes, to progress from Uncommon to Rare level, players need to achieve level 25 and have all the items for the Uncommon class installed.

To progress from the Rare to Epic class, players must achieve level 32 and have all the Rare class items installed.

To reach the Legend level, it is necessary to achieve level 38 and install all the items for the Epic class.

When a player reaches a sufficient level with their bike, they can change the class of the bike. To do this, they must have all the items for their current class and use them to transition to the new class.

When changing their bike's class, players can choose a new bike or select new characteristics for their existing bike.

The levels of the classes have the following structure:<br>

<table><thead><tr><th width="194">Class name</th><th width="225.33333333333331">Range</th><th>Upgrade to next Rarity price in MTCB</th></tr></thead><tbody><tr><td>Common</td><td>0 - 17</td><td></td></tr><tr><td>Uncommon</td><td>17 - 25</td><td>6667</td></tr><tr><td>Rare</td><td>25 - 32</td><td>7083 </td></tr><tr><td>Epic</td><td>32 - 38</td><td>10000 </td></tr><tr><td>Legend</td><td>38 - 50</td><td>37917</td></tr></tbody></table>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://crypto-bike.gitbook.io/crypto-bike.game/gameplay/nft-class-system/bike-rarity.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
