Wireless handlebar button: the problem is not the screen, it is the hand The BPU400 is a three-button remote that mounts next to the grip, so the rider can answer a call, switch screens or acknowledge an alarm without taking a hand off the bar. BLE, battery powered, IP54.

What it does

Three physical buttons on a palm-sized housing that clamps to the handlebar. Short press and long press give six separate actions. The button sends a BLE key value; what that key does is decided by your receiver or app, not by our firmware.

Pairing is deliberately physical: hold the two outer buttons for three seconds and the button broadcasts its pairing packet. No cable, no pairing tool, and nothing to configure before the first use beyond that.

Why a handlebar button exists at all

On a motorcycle or a three-wheeler, reaching for a touchscreen means letting go of the bar. That is the whole problem - not the screen, the hand. A button next to the grip removes it. The same reasoning applies anywhere both hands are busy: forklifts, agricultural machines, ride-on cleaning equipment, yard vehicles.

Because the screen print is customisable, the same hardware covers very different jobs: phone / cycle / camera icons for CarPlay and DVR head units, a tyre-pressure icon that brings the pressure app to the front, an acknowledge key for alarm handling on a machine, or any icon an OEM customer wants. The body can also be engraved with your part number.

Pairing with a tyre-pressure app

The button is a natural companion to our BLE tyre sensors: one press and the app comes to the front with the current pressure. It removes the "stop, take the phone out, unlock, open the app" sequence - which is exactly why people do not check pressure on a bike.

What we do not define

We do not define what the buttons do. You define the key codes and your app decides the action. The unit sends its key value over BLE and that is the end of our involvement in the behaviour - which keeps it usable across head units, apps and machines instead of being a remote for one product.

Ordering

One set is enough for a sample, and the bracket set is included. Tell us the icon you want on the buttons and the key codes you want them to send, and the sample is built to that.
