# Buy a bike on the marketplace

## Browse

1. Open **Marketplace** in the menu.
2. Filter by **bike type**, **country** and **year**.
3. Click a bike to open its full record: the price and where the bike is, every part, when it was last serviced, and the seller's description.

The first card shows your own free marketplace stalls — *No slots available* if you have none.

A bike listed by a shop shows the shop as the seller. Shops list from their **Showroom**.

## Contact the seller

1. At the bottom of the bike's page, under the seller's description, choose **Contact seller** and add a message if you like.

2. The seller decides whether to accept. When they do, you get a notification and can see their contact details.
3. Agree the rest with the seller directly. BikeCheck doesn't take payments for marketplace sales.

## Take ownership

When you've bought the bike, the seller sends you a transfer. Give them your **unique ID** from **Settings**, then claim the bike from your Dashboard: see [Transfer a bike](/guide/riders/transfer-a-bike.md#you-are-receiving-a-bike).

{% hint style="warning" %}
Check the serial number on the frame against the one on the bike's record before you pay. A bike flagged as stolen can't be listed or transferred.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://bikecheck.gitbook.io/guide/riders/buy-a-bike.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
