Bicycle Layer

  • This example demonstrates how to display a map with a BicyclingLayer showing bike paths and suggested routes.

  • The code uses the Google Maps JavaScript API and can be implemented using either JavaScript or TypeScript.

  • The HTML, CSS, and JavaScript/TypeScript code snippets are provided for easy integration into your project.

  • Users can explore the sample interactively on JSFiddle or Google Cloud Shell and can also clone the sample code for local execution using Git and Node.js.

This example creates a map that displays bike paths, suggested bike routes, and other overlays specific to bicycle use.

TypeScript

async function init(): Promise<void> {
    const { BicyclingLayer } = await google.maps.importLibrary('maps');

    const mapElement = document.querySelector('gmp-map')!;
    const innerMap = mapElement.innerMap;

    const bikeLayer = new BicyclingLayer();

    bikeLayer.setMap(innerMap);
}

void init();

JavaScript

async function init() {
    const { BicyclingLayer } = await google.maps.importLibrary('maps');

    const mapElement = document.querySelector('gmp-map');
    const innerMap = mapElement.innerMap;

    const bikeLayer = new BicyclingLayer();

    bikeLayer.setMap(innerMap);
}

void init();

html,
body {
    height: 100%;
    margin: 0;
    padding: 0;

Clone Sample

Git and Node.js are required to run this sample locally. Follow these instructions to install Node.js and NPM. You will also need a Google Maps API key.

The following commands clone the repository, install dependencies, and copy the environment file. 

  git clone https://github.com/googlemaps-samples/js-api-samples.git
  cd js-api-samples
  npm i
  cp .env.template .env

Once you copy the environment file, make sure to open the .env file and replace <Insert your own development API key here> with your actual API key before starting the sample. 

  cd samples/layer-bicycling
  npm start
