    The real firmware, compiled to your browser — not a video. Drive it with the controls.

    Live — your device, your controls

    Or on a keyboard: scroll · Enter select · Backspace back — hold for a long-press.

    Built for the long way round

    The things that matter when the nearest plug — or signal — is days away.

    Sunlight-readable display

    Crisp, always on, and it loves direct sun — the reflective screen reads by daylight, and only spends power on pixels that change.

    Lasts for days

    No nightly charging ritual. One charge covers days of riding — so the computer isn't the thing that dies on day three of the trip.

    Own it, fix it

    Every part is replaceable — the battery, the quarter-turn mount, the USB socket, even the buttons. Nothing proprietary between you and a repair.

    Open-source software

    Firmware, simulator, map toolchain — every line is open. Read it, build it, and change what you don't like.

    Routes to anywhere

    A campsite, a water source, the last bakery before the pass — pick a point and the device plans the route right there, in the field. No phone, no signal.

    Completely cloud-free

    No account, no subscription, no server anywhere. Maps and rides live on the device and your computer — and it all works without a phone.

    Work in progress. This site and the project behind it are still being built — wording and features will change, and proper documentation is on the way.
