420 Rear Sprocket | Surron, Talaria, E-Ride Pro, 79 Bike & More

Hardened Aluminum Performance Sprockets for Popular Light E-Motos

Changing your rear sprocket is one of the easiest and most effective ways to tailor the performance of your e-moto. Whether you're looking for stronger acceleration on technical trails or more top speed for open terrain, these hardened aluminum 420 sprockets allow you to fine-tune your bike's power delivery to match your riding style.

Manufactured from hardened aluminum and finished with a premium anodized coating, these sprockets offer an excellent balance of strength, durability, and weight savings. Multiple tooth-count options allow riders to customize gearing for everything from tight woods riding and hill climbs to higher-speed desert and street applications.

For riders looking to complete the setup, matching titanium sprocket bolts are also available separately.

*Speed estimates are based on a stock Surron Light Bee. Actual results vary based on bike model, controller settings, battery voltage, rider weight, terrain, tire size, and riding conditions.

Understanding Sprocket Changes

• Larger rear sprockets increase torque and acceleration while reducing top speed
• Smaller rear sprockets increase top speed while reducing low-end torque
• Ideal gearing depends on riding style, terrain, and power level

Important Fitment Note

This is a universal drivetrain component designed to fit many popular e-moto platforms. While it works with a wide range of bikes, fitment may vary depending on model year, wheel setup, aftermarket hubs, and drivetrain modifications.

Please verify your sprocket bolt pattern, chain type, and fitment requirements before ordering. Some applications may require different chain lengths or additional adjustments during installation.

Why Riders Upgrade Their Sprockets

Sprocket changes are one of the most cost-effective performance modifications available. Riders looking for stronger hill-climbing power, quicker acceleration, improved technical trail performance, or more top speed can dramatically change how a bike feels simply by adjusting gearing.

Whether you're riding a Surron, Talaria, E-Ride Pro, 79 Bike, RAWRR, or similar platform, selecting the right sprocket size can help maximize the performance characteristics that matter most to you.

Best For

• Trail riders looking for more low-end torque and climbing power
• Performance riders dialing in acceleration versus top speed
• E-moto owners upgrading worn sprockets or building a custom drivetrain setup
