Get the all New and Improved Qualisports Dolphin Electric Folding Bike which now comes with a powerful 48V 500W motor on board, this gives you greater power with the new Dolphin so you can ride even further than before. It will allow you to ride on hilly terrains easier. And with more torque, the new Dolphin can tow heavier and carry heavier without the rider’s extra effort. Leave the rest to the Qualibike and what you need to do is enjoy the tour.

Qualisports has developed a dual battery system, especially for folding e-bikes. You can now choose between lightweight and long-range. In your daily use, if the trip distance is not essential, but portability is more important since you may need to carry the bike around, you can choose the Dolphin, which weighs only 48lbs. If a long-range electric bike is your preference, the Dolphin Plus would be your choice; the removable main tube battery will add a 15~20miles range to the Dolphin. And the weight is 48lbs+4lbs.

The Dolphin now features hydraulic disc brakes giving far better performance for less effort. They are also a sealed system, meaning less maintenance is required following set-up.

You get a more functional display with the upgraded KT-LCD7, which comes with a USB charging port. You can add a phone holder and charge your phone while doing navigation. (NEVER text or call while riding. Safety should always bear in mind.)

The Qualisports Dolphin Folding Electric Bike comes with a conveniently hidden battery in the sliding seat post. This commuter bicycle easily folds down for convenient transportation. You can even walk it when it is folded, allowing you to navigate busy city streets and public transportation. Take this versatile sleek electric bicycle with you on your next trip!

UPGRADABLE BATTERY SYSTEM

One 48V 10.5AH lithium-ion battery, one 7AH optional lithium battery, charging time of 4-6 hours, and a range of roughly 80+ miles. The new Dolphin and Dolphin Plus have the same frame design, allowing it to be upgraded to a dual-battery version by purchasing a dual-battery kit.

CUSTOMIZED QUALISPORTS MOTOR

Climb hills and traverse crossroads smoothly and efficiently, powered by our custom 500W motor from Qualisports USA, which is designed in-house to help you go steeper at a lower speed.

QUALITY HYDRAULIC BRAKES

With fluid in the master cylinder, hydraulic brakes have a much more efficient braking mechanism to force the brake pads together when the lever is pushed. Multiplying the amount of effort put into the lever makes it easier to brake. MULTIFUNCTIONAL

LCD DISPLAY

The LCD display lets you easily see some parameters like battery capacity, current speed, pedal assist level, and travel distance. It has a USB for your phone charging.

FAQs

How far can Qualisports bikes go on a single charge?

  • Distance differs on the terrain, the weight of the cyclist, and the power mode you are using (pedal only, Full Throttle, or Pedal Assist).
  • For Single-battery Dolphin: The range is about 25 to 60 miles on a single charge using primarily electric power.
  • For Dual-Battery Dolphin: The range is about 40 to 80 miles on a single charge using primarily electric power.
  • If you use the PAS, mileage can increase.  Some riders can achieve over 60/80miles when cycling in pedal-assist mode. Thumb throttle mode will engage the motor and consume battery power more quickly.

How to turn on/off the front headlight?

  • Turn on the LCD display, and hold the display's UP button for 2-3 seconds, the headlight/LCD display background light will both be turned on.  Hold the power button the same way to turn it off.  

Is the bike pre-assembled?

  • 95% of the bikes are pre-assembled, with detailed installation videos for the front and rear fenders.
