Introducing Qualibike’s Dolphin: a powerful, long-range, and foldable electric bike. The Dolphin features a 14Ah Samsung battery, hidden in the seat post battery system, which is long-lasting, efficient, and encased with full battery-cell protection sleeve.

 

This e-bike will allow you to ride more than 50 miles with the pedal-assist mode and 30 miles range on the throttle mode in a single charge. Its rear mounted 350W brushless geared motor has been recently re-engineered, in order to achieve a more powerful and efficient motor that will endure a longer lifespan.

The Dolphin electric bike folds to a compact size to easily fit in a car trunk or under a desk. It can conveniently fold down into 32.6 x18.9 x 27.5 inch, which means it can be easily stored in tight out of the way places in your home, under your work desk, or on public transport. Additionally, weighing only 23kg, the Dolphin is a fantastic portable e-bike for urban commuters or students looking for a faster and more cost-efficient way of getting around.

Easy Fold & 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 overcharging, overheating, 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.

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.
