Why BUY the Qualisports Dolphin Electric Bicycle:

DUAL BATTERY OPTION

The e-bike with optional dual battery provides increased range flexibility for riders, allowing them to easily switch to the secondary battery when needing extra power.

Also, the removable frame battery with a built-in USB port serves as a convenient power bank, enabling riders to charge their devices on the go.

POWERFUL 500W MOTOR

The powerful motor offers strong acceleration and assists with pedaling, making it easier to tackle hills and longer distances.  In addition, the folding design allows for convenient storage and transportation, making it ideal for urban commuters and travelers with limited space.

The combination of a compact foldable frame and a high-powered motor ensures an efficient and enjoyable riding experience, suitable for various situations and terrains.

HYDRAULIC BRAKES (SAFETY FIRST)

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.

Qualified dolphin

This bike checks most of my boxes. Don't really care about the folding option & the throttle doesn't work. Needed something that would fit in my mini van sideways for camping. Didn't want with 4" tires because there horrible to ride without juice. Most bikes don't have the range that this one has. Wanted something that had gradual power so that you still get some exercise. Everything but the throttle works. I'm a cyclist so I'm planning on always peddling. This is my 2nd dolphin wanted two bikes that were evenly matched.

Thanks for your review Kevin! We've never heard of the throttle not working before. You can email aftersales@upzy.com and we can investigate further if you'd like. Thank you :)
