“One Month Charge-Free” does not mean the bike takes one month to charge.

It means that under typical commuting conditions, the Solar Wheel Charging System continuously replenishes energy and significantly reduces battery consumption.

For example, the Go6 Pro offers up to 105 miles of battery-only range. Under favorable sunlight conditions, the Solar Wheel Charging System can add up to 17 miles of riding range per day.

Assuming a typical daily commute of 20 miles, the bike is only consuming about 3 miles of net battery range per day. At that rate, a fully charged battery can last up to approximately 35 days before requiring plug-in charging.

Actual results vary depending on sunlight conditions, terrain, riding habits, and daily mileage.

PHOSGO features a Dual-Mode Solar Charging System.

• Riding Mode – Solar energy directly supports the electrical system while riding, helping reduce battery consumption.

• Parking Mode – Solar energy automatically charges the battery while the bike is parked outdoors.

The entire process is automatic and requires no rider intervention.

PHOSGO uses four integrated 50W solar panels with a total rated power of 200W.

Under favorable sunlight conditions, the Solar Wheel Charging System can generate up to approximately 50Wh of energy per hour.

Assuming about 3 effective sunlight hours per day, the system can recover approximately 150Wh of energy daily.

Based on average pedal-assist energy consumption, this recovered energy can translate into up to 17 miles (27 km) of additional riding range per day.

PHOSGO is not designed for fast charging.

It is designed for less charging.

Depending on the model, PHOSGO battery capacities range from 360Wh to 840Wh.

The Solar Wheel Charging System is not designed to rapidly recharge a large e-bike battery. Instead, it functions as a continuous energy-harvesting system that recovers energy every day.

The more important metric is not how quickly the battery charges, but how much riding range can be recovered over time.

Under favorable sunlight conditions, the system can add up to 17 miles of riding range per day and significantly reduce charging frequency.

The solar panels generate electricity that is regulated by an integrated MPPT controller, which optimizes energy harvesting and converts it into a stable charging output.

Under typical operating conditions, the MPPT system delivers a stable charging current of approximately 1.5A.

While this is lower than conventional wall charging, the system continuously harvests solar energy throughout the day, helping reduce battery consumption and charging frequency.

The wheel is one of the largest continuously exposed surfaces on an e-bike.

By integrating solar technology directly into the wheel structure, PHOSGO creates a practical and elegant way to harvest solar energy without requiring bulky external solar panels or trailers.

The result is a cleaner design, improved convenience, and seamless solar energy collection.

Like all solar technologies, solar power generation depends on available sunlight.

During heavily overcast or rainy conditions, power generation may be significantly reduced or temporarily unavailable.

This is a characteristic of all photovoltaic technologies.

To ensure reliable operation in all weather conditions, every PHOSGO bike includes a standard charger that allows the battery to be recharged from a regular wall outlet whenever needed.

The Solar Wheel Panels are engineered for real-world riding environments and designed to withstand daily use.

They are resistant to vibration, impacts, scratches, and changing weather conditions while maintaining long-term durability and performance.

The Solar Wheel Panels are designed for long-term outdoor use and tested under real-world riding conditions.

Yes.

When riding under sunlight, the Solar Wheel Charging System continues generating electricity.

During riding, the solar-generated power directly supports the electrical system and motor, helping reduce battery consumption.

This allows riders to recover energy while they ride and improves overall energy efficiency.

Yes.

When parked outdoors under sunlight, the Solar Wheel Charging System automatically generates electricity and charges the battery.

Many riders naturally leave their bikes outdoors during work, school, shopping, or daily activities, allowing the system to recover energy while parked.

All PHOSGO models are equipped with Bafang mid-drive motors.

Because a mid-drive motor works through the bike’s gearing system, it can maintain better torque and efficiency on steep climbs compared with hub-drive motors.

Depending on the model, PHOSGO delivers up to 150 N·m of torque, providing strong climbing performance for hills, bridges, and varied terrain.

Go2 (frame size：27.5”)

Recommended rider height: 5’2”–5’10” (158–178 cm)

Go3, Go5 Classic, and Go6 Classic (frame size：700C)

Recommended rider height: 5’5”–6’3” (165–190 cm)

Go5 Plus, Go5 Pro, and Go6 Pro (frame size：29”)

Recommended rider height: 5’7”–6’4” (170–193 cm)

Yes.

PHOSGO production models are designed to meet IPX6 water-resistance standards for everyday riding conditions.

The electrical system, battery system, and Solar Wheel Charging System are engineered for outdoor riding, including rain and wet-road conditions.

However, prolonged submersion or high-pressure water exposure should always be avoided.

Depending on the model, PHOSGO offers up to 105 miles of battery-only range.

Under favorable sunlight conditions, the Solar Wheel Charging System can add up to 17 miles of additional riding range per day.

As a result, the maximum daily riding range can reach up to approximately 120 miles.

Actual range depends on rider weight, terrain, weather conditions, riding style, and assist level.

A mid-drive motor drives the bicycle through the drivetrain and gear system, allowing it to operate more efficiently across different riding conditions.

Compared with hub motors, mid-drive systems generally offer better climbing ability, improved weight distribution, higher efficiency, and a more natural riding feel.

This is one reason why PHOSGO uses Bafang mid-drive motor systems across the lineup.

PHOSGO combines Solar Energy and Artificial Intelligence to create a smarter and more energy-independent riding experience.

The first generation of PHOSGO AI technology is already available on the Go6 Series through the integrated AI Voice Assistant.

Currently, AI features are available on selected models within the Go6 Series.

In the future, PHOSGO plans to introduce additional AI-powered features, including AI Vision Systems and AI Health Companion technologies, creating a more intelligent, interactive, and enjoyable riding experience.

The AI Voice Assistant currently available on the Go6 Series can assist riders with:

• Navigation Assistance

• Route Planning

• Weather Information

• Scenic Spot Recommendations

• Local Food Discovery

• Music Playback

• Ride Information

• Interactive Voice Conversation

The goal is simple: enjoy the ride.

PHOSGO supports standard AC charging using the included charger.

Depending on the model and battery capacity, charging from 0% to 80% typically takes approximately 5 hours.

This allows riders to quickly recharge whenever sunlight conditions are limited.
