750W Bafang mid-drive motor
The mid-motor makes this bike very versatile. Mid-drive motors are much more efficient than hub drives as they can use the bike's gears as transmission. Climb the steepest hills. Conquer anything.
Thumb throttle and control pad
The Biktrix Stunner Step-Over 6 750W Cruiser Mid-Drive eBike comes with throttle-on-demand and Cadence/PAS (Pedal Assist Sensor). As you pedal, the motor measures how often you're pedaling and helps you proportionally. You can boost motor performance by setting assist levels between 1 to 5 (or 1-9) levels where level 1 gives you least assist but most range while level 5 gives you maximum assist and least range. Engage the throttle, sit back, and enjoy the ride.
LCD display
The LCD display shows you all kinds of important information about your ride including speed, battery life, range, odometer, pedal assist level and more.

SR Suntour front suspension
The Suntour suspension fork helps deliver the smooth ride that the Stunner is known for.

180mm hydraulic disc brakes
When it's easy to go fast, you need strong and dependable stopping power. Safety on an eBike is key. With standard dual-piston hydraulic brakes, you can stop even faster than you accelerate. Four-piston brakes are available as an additional upgrade.

Sturmey Archer 5-speed rear hub
This bike features a 5-speed internally geared Sturmey Archer rear hub.

Integrated headlight
This bright LED is powered by the bike's battery and it can be turned on/off with a button on the handlebar control pad.

Rack and fenders
These fenders will keep you and your bike clean. Need to carry some gear? Strap onto the rear rack and make your way.

The high-step or step-over frame brings the classic cruiser style to the most comfortable riding position. This version of Stunner is very popular among men and women who don't mind swinging their legs over the seat to hop on and off the bike.
The front suspension soaks up all the bumps and adds stability while the dual disc brakes provide maximum stopping power in all conditions. This is truly the Ultimate Cruiser electric bicycle.

Three ways to ride the Biktrix Stunner Step-Over 6 750W Cruiser Mid-Drive eBike
- Pedal only (with no help from the motor)
- Pedal Assist (with up to 9 levels of assist to choose from)
- Throttle only (effortless like a motorcycle)
The Biktrix Stunner Step-Over 6 750W can be used as a normal bike where the rider provides all the power, or you can use just the throttle and let the bike do all of the work. There is also an in-between option, Pedal Assist, where the rider pedals and the motor provides a great boost at the same time. You can choose the level that is right for your type of riding. The Levels of Pedal Assist allow for increased ride efficiency, resulting in less strain on your knees while riding. It makes riding fun and effortless.
