What's in FluxKit
The complete system • Installed on your bike
In the box
Front-hub motor
A front-hub motor for the FluxKit electric-assist conversion system.
Smart battery · 480Wh
Removable battery power for everyday riding, with up to 100 km range subject to final testing.
LCD display
See ride information and assist-level controls at a glance.
FluxSense
Collision sensing and riding-awareness support to help inform your ride.
Cadence sensor
Pedal-assist response designed to support a natural ride feel.
Mobile app

In motion • What it does
Three things you'll feel on every ride.
Eyes on the road ahead
FluxSense is designed to provide collision sensing and riding-awareness support. You stay fully in control of your ride.
A rider-assist and awareness feature, not a collision-avoidance or automatic-braking system.
Every slowdown earns range back
When you backpedal, regenerative braking is designed to feed energy back into the battery. Actual range gains depend on riding conditions and final testing.
Power that comes with you
The 480Wh pack locks to your frame and lifts off in a second, so you charge it anywhere. It doubles as a powerbank for your phone or lights when you're off the bike.
How it works • Three steps
From regular bike to e-bike, in an afternoon.
Review compatibility
Check the final compatibility guidance for your specific bicycle before installation.
Install FluxKit
Final installation steps and required tools will be confirmed before launch.
Set up your ride
Use the LCD display and app controls to prepare for your ride.
The up-to-100km range is subject to final engineering confirmation and varies with rider, terrain, assist level and test conditions.
Why HyperFox
Built by engineers who ship hardware.
HyperFox started with a team of former drone engineers — people who've taken complex electromechanical products from prototype to production and know how hard the last 10% really is. The FluxKit is that same discipline pointed at the bike you already own. We're building in the open, and you'll see the real progress, not just the renders.
— The HyperFox team
EuroBike 2026 • Frankfurt
We showed up. Real booth, real bikes, real feedback.
We brought prototype FluxKits to EuroBike and spent three days watching people ride them, ask questions, and tell us what they actually wanted. That's what's going into the final product.
