Made for motion
Where will you take it?
Anywhere something moves, the sound can follow.
Bikes & scooters
Drop it into the bottle cage and turn a commute into a soundtrack. The engine rises and falls with your speed.
Toy cars & RC
Give small vehicles a big presence. The speaker reacts as they accelerate, turn, and stop.
Parties & events
Use it as a motion-reactive prop for costume parades, film shoots, or kids’ events.
Auto speed sync
Built-in motion sensing changes pitch and rhythm with movement speed.
10 selectable sounds
Sports car, truck, tractor, horse gallop, steam train and more in the mobile app.
No installation
Slides into a standard bottle cage. No tools, no wiring — lift it out when you stop.
App control
Connect by Bluetooth to select sound effects and adjust volume and sensitivity.
How does the speed sync actually work?
The speaker has built-in motion sensing. As the device moves faster or slower, it changes the pitch and rhythm of the selected sound, so a sports car engine rises as you pick up speed and settles when you slow down.
Which sounds are included?
There are 10 sound modes in total. The selection includes a sports car, truck, tractor, horse gallop, and steam train; you can browse and switch between them in the companion app.
Do I need a phone to use it?
You can play sound without a phone. The app is used to choose sound modes and adjust volume and sensitivity. Connect over Bluetooth when you want to change settings.
How do I mount it?
Slide it into a standard bicycle bottle cage. It needs no straps or wiring; lift it out and carry it when you stop. For non-bike use, set it on a flat surface.
