About Phosgo
Chasing the Light. Redefining the Ride.
What if sunlight could ride with you?
We didn’t start by building an e-bike.
We started by asking a simple question:
What if sunlight could ride with you?
At PHOSGO, we believe solar technology can do more than generate electricity.
We believe it can redefine the way people ride.
We are a team of engineers, entrepreneurs, and solar technology pioneers from Shenzhen, China, united by a shared mission:
Redefining riding through Solar and AI technology.
For more than a decade, our founding team has been dedicated to researching and commercializing advanced photovoltaic technologies.
Over the years, we have explored and developed multiple generations of solar innovations, including TOPCon, HJT (Heterojunction), CIGS, Perovskite, and the latest BC solar cell technologies.
For many years, solar energy was primarily used in utility-scale power plants and commercial rooftop systems. But we believed solar power should not be limited to infrastructure.
It should become part of everyday life.
That belief became the foundation of PHOSGO.
From Solar Technology to Solar Mobility
As flexible solar encapsulation technologies matured, solar energy gradually entered consumer applications, powering products such as portable solar panels, solar backpacks, solar power banks, and solar outdoor lighting products.
Inspired by this transformation, our team accelerated the development of advanced consumer solar technologies.
In 2023, we established a dedicated Solar Innovation Laboratory in Jiaxing, China, focused on researching next-generation solar-powered consumer products.
Over the following years, we successfully developed a range of innovative solar solutions, including:
• Solar Electric Wheelchairs
• Solar Utility Tricycles
• Solar Autonomous Delivery Vehicles
• Solar Electric bicycle
Each project brought us one step closer to a bigger vision:
Making solar-powered mobility accessible to everyone.
Then we asked ourselves a bigger question:
Could an electric bicycle power itself using sunlight?
The Dream of a Solar E-Bike
For years, solar e-bike concepts could be found everywhere—from YouTube videos and maker communities to university projects and engineering demonstrations.
Creative builders around the world explored different approaches to solar-assisted cycling, proving that the concept was possible.
Yet turning those ideas into a practical, reliable, and scalable consumer product remained an unsolved challenge.
We decided to take on that challenge.
Creating a practical Solar E-Bike required us to rethink nearly every major system of a traditional e-bike.
Over more than two years, a dedicated R&D team consisting of 5 PhDs and more than 10 engineers completed hundreds of design iterations, prototypes, laboratory validations, real-world riding tests, and pilot production runs.
The result is what we believe to be the world’s first mass-produced AI Solar E-Bike.
Core Innovations
Engineering the Solar Wheel Panel
One of the earliest challenges was surprisingly fundamental.
Traditional solar panels were never designed for bicycle wheels.
Most solar panels are rectangular.
Bicycle wheels are round.
Most solar panels are protected by rigid glass.
E-bikes operate in demanding real-world environments involving vibration, impacts, rain, dust, and changing road conditions.
There was no existing solution we could adopt.
There was no proven manufacturing process we could follow.
So we built our own.
For more than six months, our engineering team focused exclusively on developing a solar panel specifically designed for bicycle wheel integration.
We researched and refined every aspect of the manufacturing process, including:
• Solar cell layout design
• Cell string welding
• Laser cutting technology
• Waterproof encapsulation
• Surface wear resistance
To support this development, we invested in specialized manufacturing equipment, including string welders, laser cutting systems, and lamination equipment within our solar laboratory.
After successfully developing the Solar Wheel Panel, another challenge emerged.
How do you securely mount a solar panel onto a spoked bicycle wheel?
Unlike a flat surface, bicycle spokes create a complex three-dimensional structure.
The mounting system needed to be secure, visually appealing, waterproof, dustproof, serviceable, and durable enough for long-term riding.
After extensive testing and refinement, our engineers developed a proprietary anti-slip locking structure using custom-designed fasteners that securely integrate the Solar Wheel Panel with the wheel while preserving aesthetics, durability, and maintainability.
Today, this technology forms the foundation of the PHOSGO Solar Wheel System.
Intelligent Dual-Mode Solar Charging Architecture
Traditional e-bikes are designed around a single energy source: the battery.
To create a practical Solar E-Bike, we redesigned the electrical architecture of the entire vehicle.
Inspired by the energy-management philosophy used in advanced range-extended electric vehicles, our engineering team developed a proprietary Dual-Mode Solar Charging Architecture specifically for e-bike applications.
While riding, solar energy is intelligently routed directly to support the motor system, reducing battery consumption in real time.
When parked, solar energy is automatically redirected to recharge the battery.
No rider interaction is required.
The system continuously manages energy flow in the background, maximizing solar utilization under all riding conditions.
This creates a seamless solar charging experience that works both in motion and at rest.
Intelligent MPPT Energy Management
Solar energy is naturally variable.
To maximize charging efficiency, we developed a dedicated MPPT controller specifically optimized for e-bike applications.
The controller continuously tracks and optimizes solar power output, ensuring efficient energy harvesting under changing sunlight conditions while remaining compact enough to integrate seamlessly into the bicycle frame.
Conductive Hub Technology
One of the greatest engineering challenges was transferring electricity from a rotating solar wheel to a stationary battery system.
Traditional wiring solutions would twist, wear, and eventually fail.
Inspired by hub motor architecture, our engineers developed a proprietary conductive hub system that enables continuous and reliable power transmission between rotating and stationary components.
This breakthrough became one of the key enabling technologies behind the PHOSGO Solar E-Bike.
Patent-Protected Innovation
The innovations behind PHOSGO are protected by a growing portfolio of patent applications and intellectual property filings covering solar integration, energy management systems, conductive hub technologies, and related innovations.
Beyond Solar: The Future of Intelligent Riding
Many people ask us a simple question:
Why AI?
If solar technology solves the energy challenge of riding, AI can transform the riding experience itself.
At PHOSGO, we do not see AI as a marketing feature.
We see it as the foundation of the next generation of intelligent riding.
Stage One: AI Voice Assistant
The first phase of our AI roadmap is already a reality.
PHOSGO's AI Voice Assistant is currently integrated into the Go 6 AI Solar E-Bike pilot-production model, providing riders with intelligent voice interaction and hands-free assistance during every ride.
Through voice interaction, riders can access an intelligent riding assistant without taking their hands off the handlebars.
Current AI features include:
• Navigation Assistance
• Weather Information
• Route Planning
• Scenic Spot Recommendations
• Local Food Discovery
• Music Playback
• Interactive Conversation
The goal is simple:
Make every ride more convenient, informative, and enjoyable.
Stage Two: AI Vision System
Planned for the future Go X platform, with launch targeted for early 2027.
The AI Vision System is a natural extension of our team's existing expertise.
Long before PHOSGO, our engineers spent years developing vision-based products through the Mangoal brand, including advanced Dash Cam systems, image processing technologies, and intelligent video platforms.
This experience provides a strong technical foundation for bringing AI vision capabilities into the e-bike industry.
Rather than starting from scratch, we are building upon years of real-world experience in camera systems, visual intelligence, and edge-device software development.
Future PHOSGO models will integrate intelligent vision cameras directly into the bicycle platform, powered by the PHOSGO AI Vision System.
While riding, the system will recognize landmarks, buildings, natural scenery, and wildlife, combining visual information with location data to provide real-time explanations, local stories, and cultural insights.
Riders will not only travel through a place.
They will understand it.
But exploration is only part of the experience.
At the end of each ride, the PHOSGO AI Vision Assistant will automatically analyze footage captured throughout the journey, identify highlights, organize key moments, and generate a short shareable video.
With a single tap, riders can transform hours of riding footage into a polished social-media-ready story.
No manual editing.
No complicated software.
No wasted time.
Ride.
Explore.
Capture.
Let AI handle the rest.
Stage Three: AI Health Companion
Planned for the future Go S platform, currently under development and targeted for late 2027.
The third stage of our AI roadmap focuses on something even more important than the ride itself:
The rider.
To support this vision, PHOSGO plans to introduce a dedicated AI Riding Band equipped with advanced biometric sensors and powered by the PHOSGO AI Health Companion.
The system will continuously monitor key health indicators, including:
• Heart Rate
• Blood Oxygen Levels
• Breathing Patterns
• Activity and Recovery Metrics
Combined with rider profiles, weather conditions, ride history, fitness goals, and real-time physiological data, the AI Health Companion will provide intelligent recommendations before, during, and after every ride.
The system is designed to help riders:
• Monitor overall health status
• Detect abnormal conditions
• Receive wellness alerts and reminders
• Manage fatigue and recovery
• Optimize training intensity
• Build healthier long-term riding habits
But our vision extends beyond cycling.
The PHOSGO AI Riding Band is being designed as a full-time health companion that can continue supporting users during other sports and outdoor activities.
Whether riding, hiking, running, or training, the AI Health Companion will help users better understand their bodies and make smarter health decisions.
Because the future of mobility is not only smarter.
It should also be healthier.
Ride smarter.
Ride longer.
Ride healthier.
Let AI watch over the journey.
The PHOSGO AI roadmap follows a clear three-stage evolution:
Stage One — Enjoy the ride.
Stage Two — See. Understand. Share.
Stage Three — Stay healthier.
Combined with solar technology, we believe AI and Solar Technology will redefine the future of riding.
Solar powers the bike.
AI powers the experience.
