A **Fitbit** is an example of an IoT device.

### Explanation:
The Internet of Things (IoT) refers to the interconnection of devices that communicate and exchange data over the internet. A Fitbit, as a smart fitness tracker, is designed to collect data on physical activity, heart rate, and other health metrics, which it can then send to the internet for analysis and tracking.

In contrast:
- A **landline telephone** does not typically connect to the internet or send data.
- A **bicycle** by itself is not a connected device unless it has smart technology integrated.
- A **railway car** generally refers to transportation vehicles that do not inherently function as IoT devices unless fitted with specific technology.

### Final Answer:
