Luck4U Tuningchip 38km/h /20km/h- Xiaomi 1S/Pro/Pro2

Product: Luck4U Speedhack tuning chip for Xiaomi 1S / Pro / Pro2 scooter – 38 km/h and 20 km/h modes

The Luck4U Speedhack tuning chip is designed for riders who want more dynamic performance from their Xiaomi scooter. It allows you to increase the factory top speed up to 38 km/h or, if preferred, limit it to 20 km/h for a calmer ride. This makes it a flexible solution for closed tracks or private property, where you can fine-tune your scooter’s behaviour to your needs.

• Xiaomi Mi Electric Scooter 1S
• Xiaomi Mi Electric Scooter Pro
• Xiaomi Mi Electric Scooter Pro 2

Key features

• Two speed modes: low mode up to 20 km/h, high mode up to 38 km/h (depending on load and conditions)
• WiFi configuration for adjusting key settings such as button presses required for speed change, cruise control and rear light functions
• Dedicated design for Xiaomi models – not a universal workaround, but a tailored solution
• Compact module that fits into the handlebar stem without affecting everyday use
• Balanced acceleration and stable power delivery for a more responsive ride

Installation suggestion
