Quality in the Details

Throttle & Pedal Assist Control
Easily switch between pedal assist and thumb throttle through an intuitive control panel. Enjoy immediate acceleration for quick starts or heavier loads, paired with torque-sensing assist for a smooth, natural ride.

Torque Sensor Boost
The torque sensor ensures smooth launches and confident climbing, even when carrying extra weight—delivering a natural ride feel and up to 30% more range than cadence-based systems.

Comfort-Focused Performance

The low-step carbon frame combines accessibility with performance, offering a lightweight yet durable structure that enhances comfort and control in daily city use.

Throttle & Pedal Assist Control
Seamless transitions between pedal assist and throttle provide flexibility for commuting, errands, or leisurely rides, with smooth power delivery at every speed.

Torque Sensor Boost
Designed for efficiency and responsiveness, the torque sensor adapts to your pedaling effort for consistent power and extended range.

Adjustable Handlebar
The 0–90° adjustable handlebar fits riders of nearly all heights. Shift easily between a relaxed upright posture and a sportier riding position for all-day comfort and control.

Cushioned Saddle for Miles
A wide, shock-absorbing saddle offers long-lasting comfort, while the adjustable seat post ensures an ideal fit for riders of almost any height.

UL-Certified, Removable Battery
Ride up to 75 miles per charge with the 352.8 Wh Samsung Li-ion battery, UL 2271 certified for safety. Its removable design makes charging convenient at home, at work, or on the go.

Power, Control, and Security

Powerful Motor & Shifting
The 750W peak motor delivers strong, responsive acceleration for hills and heavier loads. Combined with a Shimano 8-speed drivetrain, it provides smooth, reliable shifting across flat roads and winding paths.

AirTag Mount — Never Lose Your Bike
An added layer of theft protection allows you to discreetly mount an AirTag on your e-bike, giving you peace of mind through reliable tracking.

LCD Color Display & USB-C Charger
The bright LCD color display clearly shows speed, battery level, and assist mode—even in direct sunlight. A built-in USB-C port lets you charge your phone while riding.

Hydraulic Disc Brakes
180mm hydraulic disc brakes deliver powerful, responsive stopping in all conditions. Cut-off brake levers instantly disengage motor power when braking for safer, more controlled rides.

Customized Fenders and Rear Rack
Durable fenders protect against mud and rain, while the custom rear rack increases versatility—making it easy to carry daily essentials or travel gear.

Gear Up, Go Far
