Longer range
Each ride puts some energy back into the battery. The same pack covers more distance between charges.

Range, rewritten.
An in-wheel generator for electric scooters. It tops up the battery as you ride, so every charge goes further.

01 / The opportunity
More range,
More range,
from the same battery.
Scooter riders don't need a bigger battery. They need the one they have to go further. Helios recovers power from the wheel as it turns and feeds it back to the battery.
Simple to fit
One unit in the wheel hub. No extra engine, no extra fuel, no extra wiring loom.
Fewer partsLower mass
Fewer charging stops
Riders plug in less often. Delivery and sharing fleets keep scooters on the road for longer shifts.
Longer shiftsFewer charges
Easy on the battery
Ultra low starting resistance and gentle charge cycles help the battery last longer.

Why it matters
Built to keep going.
Range extended with every kilometre ridden. Fewer charging stops on long days. Less strain on the battery over its life.
Zero tail pipe.
Nothing comes out of the back. Not a drop of fossil fuel. Carbon neutral rules met, not chased.
Charge less often.
Recovered power tops up the battery while riding. Low wear, low maintenance. Batteries cycled gently, so they last longer.
Low voltage start.
Starts at low voltage, so electrical risk stays low. Built with mechanical redundancy. Stays in service when others stop.
Drop in wheel.
Swaps straight in for a standard scooter wheel. Fits 12, 16 and 18 inch hubs. Existing scooter platforms welcome.
Two technologies, one system.
Helios Motor moves the vehicle. Statorless generator powers everything else. One complete on board system.

06 / Before you ask
Asked often.
Asked often.
Answered straight.
What it does. Who it's for. How to begin. The engineering stays between us and our partners.
01Where does the power come from?
From the wheel's own motion. As the scooter moves, the in-wheel generator turns some of that movement into electricity and feeds it back to the battery. We walk scooter makers through the engineering under NDA.
02Does the scooter still need to be charged?
Yes. Helios is a range extender, not a replacement for charging. The scooter keeps its normal battery and charger. The generator tops the battery up while riding, so it needs charging less often.
03How is this different from a normal hub motor?
A normal hub motor only drives the wheel. The Helios hub pairs the drive motor with a statorless generator in the same space, so the wheel also recovers power as it turns.
04Doesn't generating power slow the scooter down?
The Helios hub is designed to keep mechanical load low, with starting resistance around 60% lower than a conventional unit in our testing.
05What does it do for running costs?
Fewer charging cycles and gentler use of the battery, which helps the battery last longer. Fleets that run long shifts benefit most.
06Is this a retrofit product?
It is designed to be fitted by scooter manufacturers at the factory. The hub drops in for a standard 12, 16 or 18 inch wheel, so existing scooter platforms can use it without a redesign. We sell to scooter makers, not individual riders.
07Is it certified?
Not yet. Independent performance testing and certification are part of the current development phase.
08Which scooters can use it?
Two wheelers with 12, 16 or 18 inch hubs. Other sizes can be discussed.
09Can it handle tropical weather?
The generator is rated to 180 °C and built for outdoor use in heat and rain.
10How far along is the technology?
Working prototypes have been built and tested in house. The current phase is refining prototypes, arranging independent testing and preparing patent applications, with production planned over the next one to three years.
11Can I see the technical specifications?
Yes, under a non-disclosure agreement. Performance data, drawings and integration documents are shared with scooter makers once an NDA is in place.
