The Bike Module.

Your Bike Module gives you support on a handlebar, whether it’s a bike, scooter, lawn mower or shopping cart.

The bike module design.

Use the Bike Module if you want more balance for your bike or scooter ride. Thanks to the flexible insert, the module fits on different handlebars. Ride curves comfortably, thanks to the built-in joint.

Module Function No. 1

The Bike module is equipped with a pivot joint. This allows you to easily bend your arm during use, e.g. when cornering.

Module Function No. 2

You can rotate the Bike module once completely around its axis. This allows you to align it differently, e.g. for vertically aligned bike handlebars. You can also choose to keep a free rotation of the module.

Module Function No. 3

You can use the Bike module with different "tongues" by clicking them in and out. The standard tongue is used to ensure that your bike module flexibly grips the bike handlebar. To do this, gently press the Bike Module onto the handlebar. Because the tongue is flexible, you can also release the module from the handlebars.

Module Function No. 4

You can easily align the Bike module with the help of the shaft ring as you need it for your activity.
