Pre-Order — Ships Spring 2026
Three Steps. That's It.
Pair the App
Download the free LOY EYES app (iOS & Android). Connect via Bluetooth — takes 10 seconds.
Upload Your Design
Pick from 200+ presets, or upload your own text, images, and GIFs. The app converts everything to the 48×48 LED matrix automatically.
Ride Bright
Power on with any USB powerbank. Your design plays instantly. Switch designs on the fly from your phone — no stopping required.
Every Feature, Explained
Programmable LED Canvas
The 48×48 full-color matrix is your screen. Display scrolling text, pixel art, logos, or full GIF animations. The free LOY EYES app converts anything you upload into LED-ready format — no design skills needed. 200+ preset animations included.
Brake Light Visibility
Map a full-screen red flash to a shortcut and trigger it when you slow down. Drivers behind you react like you're a rolling traffic light. The screen is bright and readable in direct sunlight — critical for daytime riding safety.
Helmet Storage Compartment
The dedicated exterior compartment fits most full-face, modular, and open-face helmets. Park your bike, stash your lid, walk in hands-free. When not in use, the compartment flattens completely — zero wasted pack space.
Waterproof Armored Shell
ABS+PC hard shell with sealed electronics and water-resistant zippers. Rode through a Colorado downpour? Backpack soaked outside, gear bone dry inside. The shell also provides aerodynamic stability at highway speeds.
Obsessed With Details
Every component chosen for durability, function, and that unmistakable Black Knight aesthetic.
Carbon Fiber Hard Shell
ABS+PC armored construction with carbon fiber texture. Aerodynamic, impact-resistant, premium feel.
Reinforced Straps & Buckle
Military-grade quick-release chest buckle. Padded ergonomic shoulder straps with ice-blue accent stripe.
Water-Resistant Zippers
Rubberized YKK zipper coating keeps water out. Sealed seams throughout.
Hydrophobic Surface
Water beads and rolls off. The shell's coating repels rain on contact.

What Riders Say
“Cars actually keep distance now. Loaded a big red exclamation animation for braking — drivers behind me react instantly. The mechanical eyes at night look absolutely menacing in the best way.”
Marcus T.
Austin, TX
✓ Beta Rider Program“The LOY EYES app is dead simple — upload a GIF and it just works. I run my own pixel art on my morning commute. Got stopped at three red lights by people asking where I got it.”
Jenny K.
Los Angeles, CA
✓ Beta Rider Program“Rode through a Colorado downpour. Backpack soaked on the outside, gear bone dry inside. The helmet compartment alone is worth the price — no more carrying my lid around by the chin strap.”
Derek W.
Denver, CO
✓ Beta Rider Program“Runs a full week of commuting on my 10,000mAh powerbank. Group rides look unreal when everyone syncs animations. Only wish the screen were bigger — but the pixel art aesthetic has grown on me.”

The Black Knight features a 48×48 full-color LED matrix built into the front of a waterproof ABS+PC hard shell. It connects to your phone via Bluetooth, and the free LOY EYES app (iOS & Android) lets you display text, images, GIFs, and animations. The signature Iron-Man mechanical eye design comes preloaded and turns heads everywhere.

The Black Knight is powered by any standard USB powerbank (cable routes internally — nothing dangling). A 10,000mAh powerbank runs the screen for 8–10 hours. You can use your own, or add our tested 10,000mAh option at checkout.
Yes — that's the whole point. The LOY EYES app lets you send clipart, your own images, scrolling text in any color, and GIFs. It converts everything automatically to the 48×48 LED matrix format. There's also a library of preset animations included.
Yes — many riders map a full-screen red animation or flashing pattern to a shortcut in the app and trigger it when slowing down, making you dramatically more visible in traffic. The screen is bright and readable day and night.
The dedicated helmet compartment fits most full-face, modular, and open-face helmets. When not in use, the compartment flattens so it doesn't eat your pack space.

The electronics are rated for -20°C to 50°C (-4°F to 122°F). In extreme cold, powerbank output may drop somewhat — standard lithium behavior.
Wipe the hard shell with a damp cloth. Avoid submerging the backpack or pressure-washing the zipper area. The LED panel surface cleans with a microfiber cloth.
