YCF Transmission Upgrade Kit – 16eMini

More torque. Stronger pull. More aggressive response.
Transmission upgrade kit designed for the YCF 16eMini to increase torque, improve acceleration and transform overall bike performance.

“The bike lacked torque off the line and felt too smooth. After the transmission upgrade, it pulled harder and felt much more responsive.”
Typical situation. The stock gearing is balanced, but limits low-end power and traction.

Why upgrade the transmission

• More torque: significantly stronger output from the drivetrain
• Sharper acceleration: improved throttle response at low speed
• Better control: easier to manage in technical sections
• Effective upgrade: boosts performance without changing the motor

Compatibility

• ✔️ Compatible with YCF 16eMini
• ❌ Not compatible with other YCF or STACYC models

Key features

• Stock setup: 11T front sprocket / 55T rear sprocket / approx. 5:1 ratio
• Upgraded setup: 9T front sprocket / 65T rear sprocket / 140-link chain
• Final ratio approx. 7.22
• Designed to increase torque and throttle response

Usage & installation

• Upgrade from stock transmission
• Improves traction and low-end response
• Requires access to drivetrain components

Important: this setup increases torque without significantly increasing top speed.

Installation requires basic mechanical knowledge. Replacing sprockets and chain involves partial disassembly. Improper installation may affect performance or cause premature wear.
