Qualisport 02 Dolphin Key Features
The Qualisport 02 Dolphin Folding Electric Bike beautifully combines power, versatility, and comfort into a truly unique package that’s comfortable in the concrete jungle and city streets.

Motor
Customized 350W high speed geared brushless motor weighs only 2.2KG yet still has 40 N.M torque, that gives you enough power to climb uphill at over an 18° incline. It’s so powerful that you don’t have to worry about hills or against wind without any sweat. What’s more, with a built-in clutch, you will never feel any magnetic resistance when riding without any power—it’s a purely comfortable ride.

Disk Brakes
Front and rear disc brakes keep you safe from any emergency with a braking distance within 3 meters. The e-bike safety lever is another safety feature on this bike, it shuts down the power system right away if you use the break.

PAS Ridng System
Multi function LCD display,12 points sensor and FOC controller work together for the PAS system. You can either ride in peddles mode, or at cruise control mode without peddling or pure bike mode if you need some exercises. The sensors can detect every intention precisely.
