Highlights
High-Performance Power for Daily Adventures
Equipped with a 48V peak 500W brushless motor and a removable 48V 13Ah lithium-ion battery, the M-RAX delivers smooth acceleration and reliable performance for commuting, fitness rides, and outdoor exploration. Enjoy a pedal-assist range of up to 60–80 km per charge for worry-free riding across city streets and light off-road terrain.
Durable 27.5" All-Terrain Frame
Built with a lightweight 6061 aluminum alloy frame featuring a sleek weld-free design, the M-RAX combines durability with modern styling. The 27.5" × 2.35 all-terrain tires provide excellent grip and stability, while the lockable front suspension fork helps absorb shocks for a smoother ride on uneven roads and trails.
Shimano 21-Speed Precision Shifting
The SHIMANO 21-speed drivetrain and durable KMC chain offer smooth, responsive gear changes for climbing hills, accelerating on flat roads, and adapting to changing terrain. Designed for efficiency and control, it enhances both urban commuting and recreational trail riding.
Smart LCD Display & Enhanced Riding Safety
An integrated LCD display keeps key riding data within easy view, including speed, battery level, distance, and assist mode. Convenient handlebar controls allow quick access to lighting, horn, throttle, and gear adjustments. Bright LED front and rear lights improve visibility and safety during early morning or nighttime rides.
Comfortable Ergonomic Riding Experience
Designed for riders 165–185 cm tall and supporting up to 120 kg, the M-RAX focuses on everyday comfort and riding stability. The ergonomic frame geometry, adjustable saddle height, and upright riding posture help reduce fatigue, making it ideal for commuting, leisure rides, and weekend adventures.
