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 current output.

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-fuction 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.

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.

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 heavier cyclists.
