Your wheel already knows when you brake, turn, or hit a hazard. LumpiApp takes that and makes your lights react on their own — brake flares red, a lean signals a turn, a honk strobes a warning — with a live ride dashboard on your phone and watch. The prototype rides today; pre-orders for the first batch are coming soon.
A small smart module reads the wheel over Bluetooth and answers in light — automatically, the moment it matters. This part isn't a promise; it rides today.
Slow down and your brake light flares, so the rider behind reads it instantly.
Lean into a turn and an amber signal blinks the direction — no buttons, no fuss.
Hit the horn and the lights strobe a warning, turning a sound into something people see.
A serious rider carries a small stack of tech — the wheel, lights, maybe a camera, a heads-up display, a comms headset, the gear itself. Today none of it talks to each other. LumpiApp is the layer that connects them: the wheel already knows what's happening, and LumpiApp speaks that one truth to everything else on the ride at once. One language, one ride.
It's the same move CarPlay made for the car — not another gadget on the dashboard, but the connective layer that makes what you already own work together. Some of it rides today; the rest is the direction we're building toward, described honestly as a roadmap, not a shipped promise.
Every piece is built on industry-standard, pre-certified modules and speaks the same language, so it just works with the rest.
The smart module that makes the ride reactive. Hold it in your hand, wear it on your wrist, or clip it to a socket-mount on your gear or wheel. One brain, three ways to carry it.
Rides todayThe budget way in: a simpler, lower-cost module with a small display, so a new rider can get reactive safety lighting without buying the flagship first.
Entry model · in developmentA transparent heads-up display we're designing to put what matters — speed, a live turn signal, a hazard — in your line of sight, so you read the ride without looking down.
On the roadmapA maker's carrier that the SERO brain seats into, breaking out servos, sensors, extra light channels and more — the board you build your own Lumpi.app-powered device on.
For makers · roadmapOnly SERO's reactive lighting rides today. POKEET, PILIK and Hero SERO are the lineup we're building toward — a direction, not a set of dates or promises.
Lumpi.app isn't just a light — it's a small, honest platform for reactive gear. Here's what you get to build against.
A carrier board that seats the SERO brain and breaks out a menu of hardware — servos, sensors, light channels, an I2C backbone — so you can prototype your own device on a brain that already speaks the ride. A maker dev-kit we're designing; it doesn't exist yet.
In design · roadmapAuthor your own lighting effects and tune how the ride looks, right from the app — no toolchain, no reflash. This part is live.
Rides todayAuthor an effect, submit it for approval, and share it with other riders. A simple, moderated way for the community to make the lineup its own.
Rides todayEach device tells the app what it can actually do, and the app shows only the controls that apply. Add a capability and the right UI appears — no app update per accessory. It's the contract an add-on builds against.
Live · expandingWe're building Lumpi.app to plug into the gear riders already trust — and to let other makers build on it too.
Design and sell your own reactive, Lumpi.app-powered products — built on the same brain, the same app, the same connected ride.
Build a snap-on accessory or a lighting-enabled part against a published interface, so it works with the ride without touching our silicon.
Helmets, HUDs, comms, cameras, protective gear, accessories — if it rides, it can speak the same language. A concept we're opening, not a deal we're claiming.
Everything above is a direction we're building toward. If you make gear for riders, the honest version of where we are lives behind sign-in.
