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
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.

I bought this bike to be more green. I love the way it drives. With and without batteries. I had a minor issue but their customer service is helping every step of the way. I love this cargo bike, and for the money you can’t do better. Thanks for a cool product
My e-trike is so much fun! I’ve had so many people ask me about it.
I can run so many errands with it - forget the car!
Love my bike! It was simple and easy to put together. I use the throttle to start off rather then peddling to start as it’s easier and I can control the speed better.
The EUNORAU FAT-HS Fat Tire is hefty but fun. Great for commuting and moderate single track riding. Zoom provided responsive service.
I love the bike,it rides great. I have yet to really push it but so far so good. Zoom bike has been very professional. I'm satisfied all the way around
I want to thank Zoom for a great bike , very easy to assemble. I find myself waiting for the next opportunity to venture out on my e bike. I’m a middle aged man so I can appreciate the ride this bike offers. A+
Wish I could picture but it’s all decked out and hunt ready and can carry ALOT of weight.. it’s a work of bike art and a true blessing to own!! Thanks 🙏
Great ebike for the price and so much fun riding to the beach. Great value!
Extremely satisfied with purchase of The Revi Predator.. I have put it to a moderate test as a novice rider. To streets and trails it’s smooth and seems well built to a grade heavy duty in my opinion. Shipped from Zoom warehouse in California to central indiana In within 10 days.. Package well. And Assemble within 30 minutes.. Tools required were included, Before first ride.. Insure handle bars are correctly tighten. fork nut was Lose as I made my first voyage. simply tighten. I recommend the product and Store and can validate satisfaction.
The electric bike is so fun to ride... Only issue is instructions and putting it together
This bike is solid and very convenient in all aspect. The price, the power, and the comfort is unbelievable. I ride a lot for fun and I also ride to work sometimes and it is always comfortable. After logging so many miles on it looks like new!
I've had this bike about 4 months now, and it's made my life so much easier, especially now that I can use it for trips that I used to take public transportation; was never a fan of waiting for the bus. Also, fyi a speedometer sign clocked at 22 mph. One drawback is that the front brakes were not "plug and play;" they dragged; I didn't have the skills to adjust, them so took them off; had to have the bike mechanic reattach them. One more drawback that surprised me: I live in Chicago, a big city, but I was lucky because THE LOCAL BIKE REPAIR HAS THE ONLY MECHANIC IN THE CITY WHO WORKS ON ELECTRIC BIKES. Another mechanic said he and his colleagues are wary of them because the components are not standard; they vary depending who the manufacturer is.
