While the newest Ultra Bee arrives with a 74V battery that offers a significant range over the Light Bee, the Electric Cycle Rider offers an even higher capacity 81.4V 73Ah battery from EWATT, which significantly increases power output. 

Check out our wide range of Surron Ultra Bee chargers and accessories that help power your dirt bike and make charging more convenient.

1. Charging Your Ultra Bee Battery—Don’t Just Plug and Go

Your Ultra Bee’s charger supports three power modes:

• U1: 480W

• U2: 750W

• U3: 1100W (maximum)

Choose the one that matches your local voltage and the charger’s capacity. Don’t force it—a mismatch can damage the system.

⚠️ Important Charging Tips:

• Never charge below 0°C (32°F)—this can cause permanent damage.

• If the battery is hot after a hard ride, wait at least 30 minutes to cool down before charging.

• Unplug the charger immediately after it’s full—don’t leave it overnight.

• Only use the original or manufacturer-approved charger. Unverified chargers are a fire risk.

• Customizable driving modes for a tailored experience.
• Reverse gear: ideal for maneuvering in tight spaces.
• Smooth mode switching to adapt to every terrain.
• Traction control for optimum stability, even at high top speeds.
• Circuit breaker and on/off switch for added safety.
• Communication with the original BMS, ensuring reliable use of lithium-ion batteries
