Unlimited range, zero downtime and zero running costs—transforming last-mile delivery, emergency response and marine mobility.
JAVEA, Spain - Gray Smith, today announced a disruptive technology set to redefine electric mobility: a patented self-charging power system for e-cargo bikes. This innovation eliminates range limits, removes charging downtime entirely, and creates fully autonomous electric transport with no running costs.
Designed as a "kit" for all legal e-cargo/e-bikes and emerging micro-EV platforms, the LoopyWatt has continuous operation for logistics, delivery, public services, and even military use.
A New Era for E-Cargo Transport
E-cargo bikes are rapidly replacing vans in cities worldwide due to laws restricting 7.5-tonne vehicles, congestion zones, lane closures, and new clean-air regulations. But they have a critical flaw:
Their batteries only last 50–70 miles and require up to 7 hours to recharge.
The LoopyWatt system solves this permanently.
How it Works
- A patented 450W charging unit — the round aluminium module mounted at the rear on the prototype.
- One battery powers the bike while the second battery is automatically charged.
Avoiding magnetic field resistance. Using smaller AMP batteries - When the first battery is nearly empty, LoopyWatt's electronics seamlessly switch over to the now fully charged battery
- The rider continues with no waiting, no cables, and no mains charging required.
Outcome:
A bike that can ride indefinitely.
A fleet that never stops.
A business freed from charging schedules, downtime, and electricity bills.
Surplus energy to run:
- Heated "hot-food" infrared mats for deliveries
- Refrigerated/insulated compartments
- Sensors & video IT systems
- Emergency service vehicles enabled
Transformational Applications
Logistics & Delivery
- Supermarkets: cold-chain continuity, no melting, no spoilage
- Restaurants: hot-food delivery without thermal loss
- Parcel delivery: never stop, never swap over batteries
- Courier fleets: peak-time reliability and all-day operation
Emergency Services
E-cargo units powered by LoopyWatt could bypass traffic and reach critical incidents faster than standard vehicles:
Military & Off-Grid Use
The system is silent, off-grid, and requires no external power: Behind-the-lines mobility Reconnaissance
Manufacturer Partnerships & Exclusive Licensing Now Open
LoopyWatt is now accepting commercial discussions for:
- Manufacturers purchasing the self-charging Kit
- Exclusive country-by-country licensing is possible.
What the Inventor Says
"This technology removes the single greatest barrier in electric mobility: the need to stop and charge.
With LoopyWatt, e-cargo bikes and boats become truly unlimited. No downtime, no electricity cost, and no emissions.
We monitor a rider's health live. Using AI for HRV, BP and breath frequencies. With live video. We can stop a bike and call first responders."
