    Affordable: for an e-bike with its premium specs, this e-bike is one of the most affordable folding electric bikes on the market.

    Unique: the Dolphin has a patented and unique battery and electrical system. From first sight, it doesn't even look like an electric bike. That's because the battery and electrical system are embedded inside the seat post and frame. The battery can also be removed for charging. This gives the Qualisports Dolphin a very unique beautiful look that sets it apart from other folding e-bikes on the market.

    Easy to ride: you can ride your Dolphin using only the throttle if that’s what you want. That means you can just sit back and relax while the motor does all the work. However, the great thing is that you can also get a bit of a workout on this electric bike using the pedal assist (5 levels). You can also use the mechanical shifter to ride this e-bike like a regular bike without using any power. You have all the control you need.

    Powerful: featuring a powerful 350W rear hub motor and a large capacity 36V/14Ah battery, there is nowhere in the city this e-bike can't take you. You can easily get a 60+ mile range with pedal assist (PAS) and a 30 mile range with the throttle on the Dolphin. Steep hills won’t also be an issue with this e-bike!

    Comfortable: the Dolphin folding electric bike is designed with comfort in mind, so you’ll be able to ride it for hours without feeling any discomfort. The unique 2.35″ tires will make your rides smoother, faster and quieter than other similar folding e-bikes on the market. The Dolphin also features a comfy saddle which will give you extra comfort when riding.

    Safe: on top of the rigid 6061 Aluminum Alloy frame, this e-bike also comes with mechanical disc brakes. This is a perfect fit for its powerful motor. Your Dolphin will stop immediately after you hit the brakes. The motor inhibitor feature will also allow you to override the throttle and pedal assist so your Dolphin stops faster.

    Extra features: the Dolphin comes with fenders which will keep you dry during rainy days. It also features a front and tail light, flick bell and an adjustable kickstand.
