Revolutionary Self-Charging E-Bike Charger
It's Finally here
The Wait is Over, LoopyWatt Has Arrived.
The world’s first self-charging power system designed for e-cargo bikes and e-bikes is finally here — and it’s changing everything.
Meet Gray Smith from Jávea, Spain — the inventor behind the patented Loopywatt self-charging unit. His passion is unmistakable: after years of development, he still can’t stop testing the bike that charges itself as it rides.
No plug-in. No downtime. No limits.
For e-cargo companies, that means continuous operation with zero running costs — and for riders, the freedom of truly limitless distance.
Explore our gallery showcasing real-life testing at 12, 24, 36, and 48 volts — delivering consistent, reliable results every time.
We currently offer the complete self-recharging system — including all required electronics — for e-cargo bike manufacturers. (An e-bike version will be available soon.)
We also provide licensing opportunities in select countries and are open to commercial partnerships. Please note that this system is patented, with multiple intellectual property claims in place.
From Concept to Perfection
Tested, Refined, and Ready for the Road
before perfection
After years of rigorous testing, iteration, and field data collection, Loopy Watt is no longer a prototype — it’s a perfected power system.
From the earliest concepts to the final patented design, we've created a system that delivers consistent, intelligent charging for both e-bikes and e-cargo bikes.
It’s not theory — it’s real-world innovation, validated by science and performance.
One of our first attempts
How It Works
Riding Just Became Charging
Loopy Watt harnesses motion and multiplies it.
As you ride, it begins generating power from as low as 6.4 km/h (4 mph) — no pedaling required. Whether installed on the front wheel (e-bikes) or through a belt-drive system (e-cargo), its patented mechanical-electrical multiplier converts rotational energy into direct battery power.
Our proprietary multi-voltage regulator delivers charging directly to the battery at the voltage it needs — 12V, 24V, 48V, or even 60V — depending on your speed.
No more charging from the wall
No range anxiety
Just ride, and recharge on the go
This is not perpetual motion.
This is physics, engineered to perfection — and protected by patent.
Powerful Real-World Data
Backed by Performance
Loopy Watt delivers serious power, intelligently adjusted to your speed:
-
4 mph (6.4 km/h): Starts to generates 400 watts at 24V
-
7 mph (11.2 km/h): Now generates 400 watts at 36/48V
-
10 mph (16 km/h): Now generates 450 watts at 48V
-
13+ mph (21 km/h): Now generates 450 watts at 48V to 60V
It automatically manages battery input to maintain a level between 65% and 100%, dramatically increasing battery lifespan and eliminating deep discharge cycles.
450 watts of continuous, on-the-go power — enough to ride indefinitely.
Not Magic, Just Science.
Loopy Watt is not a perpetual motion machine — it’s real-world physics, harnessed with cutting-edge electronics and a patented multiplying system.
Our solution obeys every law of energy conservation, using the momentum of your ride to create a closed-loop charging cycle that enhances efficiency and performance.
We're Ready for the Next Chapter
