Choose between the Purion 200 or Kiox 300 display for intuitive control, allowing you to adjust settings, monitor performance, and navigate with ease - all from your handlebars or directly through the app. With smart technology at your fingertips, the Roadster4 keeps you connected and in command, wherever your ride takes you.
Key Features of the Roadster4

Carrying essentials is effortless with the choice of a rear carrier featuring the Racktime Snapit system or a front luggage rack, making the Roadster4 as functional as it is dynamic - perfect for fast-paced commutes, city errands, and longer weekend rides.
