What our customers say:

EASY FOLD AND EASY GO

Qualisports folding structure makes the folding size only 830*480*700mm, weighing only 50lbs.

It can easily fit in the back of an SUV, in the trunk of a car, RV, and easily folds for ease of transportation.

BIGGER BATTERY

The Dolphin features a 14Ah Samsung battery, hidden in our patented seat post battery system that lasts longer, is more efficient and encased with full battery-cell protection sleeve. This e-bike will allow Qualibikers to ride between 50-60 miles of utilizing the PAS (Pedal Assist) mode and 30 miles range on the throttle mode in a single charge.

The intergraded customized BMS system protects the battery from over charging, over heating, stabilizes and regulates the current output.

SMOOTHER RIDING

The Re-programmed FOC controller offers Quali-bikers a more enjoyable and comfortable riding experience.

This is accomplished by the integration of our components mentioned above to provide a smoother fluid motor engagement.

We also intergraded a multi-function LCD display on board together with a 12 dots Cadence Sensor to help the riding experience more enjoyable. The LCD panel has the following visual indicators on it. 5 levels of PAS (Pedals Assist levels - 5 levels), battery level indicator, timer, speed, distance, average speed, trip distance, trip timer, ODO, max speed, battery voltage indicator, Lamp on/off, back lights, walking mode and cruise control mode.

STRONGER MOTOR

The rear-mounted 350W brushless geared motor has been re-engineered from inside and out. New material was utilized in the gears producing a stronger magnetic field is applied inside the motor which achieves a more powerful and efficient motor that will endure a longer lifespan.

STRONGER FRAME

The Dolphin has been crafted and tested under our strict guidelines and procedures. The frame is made of 6061 Aluminum which is an industry-standard known for its lightweight and strength, allowing our bikes to appeal and support heavier cyclists.
