Description
The KOOLUX X9 Pro combines rugged fat‑tyre performance with the flexibility of single or dual battery power. It’s engineered for long‑range comfort and adaptable speed modes, making it ideal for commutes, off‑road trails, and extended adventures.
Smooth Power Delivery
The 250 W continuous‑output motor (750 W peak) delivers strong torque for hill climbs and quick starts. Five levels of pedal assist plus a throttle mode let you tailor power to your ride.
Comfort & Control
Wide 20″×4.0″ tyres and a front suspension fork absorb bumps on gravel, sand, or uneven pavement. Hydraulic disc brakes provide reliable stopping power in rain or shine.
Smart Battery System
Choose a single battery for lighter weight or dual batteries for maximum range. Removable, lockable packs charge in under nine hours and include built‑in protection against over‑charge, over‑discharge, and overheating.
Tech You Can Trust
The clear LCD display shows all ride metrics at a glance. Simple handlebar controls let you switch assist levels, toggle the throttle, and lock/unlock the system.
Built for Everyday Use
With its fold‑ready frame, sturdy rack and mudguard mounts, and splash‑proof design, the X9 Pro is ready for daily commutes, weekend explorations, or multi‑day touring—wherever the road (or trail) takes you.
