FEATURES

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.

FAQ

How far can Qualisports bikes go on a single charge?

Distance differs on the terrain, weight of the cyclist, and the power mode you are using (pedal only, full Throttle, or pedal assist).

For a Single-battery Dolphin: The range is about 25 to 60 miles on a single charge using primarily electric power.
For a 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.

How to turn on/off the front headlight?
Turn on the LCD display, 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.
