Qualisports | DOLPHIN 48V 10.5Ah 500W Folding Electric Bike

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.
