      Qualisports DOLPHIN 350W 36V is an affordable and sleek folding bike that hides its electric system in the frame and seat post, MXUS hub-drive, 36v 14ah Samsung battery, 7 speed Shimano cassette, thicker tires, and mechanical brakes with motor inhibitors.

      This e-bike will allow you to ride more than 60 miles with the pedal assist mode and 30 miles range on the throttle mode in a single charge. Its rear mounted 350W brushless geared motor has been recently re-engineered, in order to achieve a more powerful and efficient motor that will endure a longer lifespan.

      The Dolphin electric bike folds to a compact size that easily fits in your car trunk or under a desk. It can conveniently fold down into 32.6 x18.9 x 27.5 inches, which means it can be easily tucked away in your home, under your work desk, or on public transport.

      The bike folds well, you can walk it when folded or even slide the seat post down through the frame to use it similar to a chair, allowing you to sit on the saddle of the bike while it is folded in a stable manner

      The Dolphin comes in 2 colors, matte black and dark metallic gray.

      Driving the Dolphin is a planetary geared hub-motor from MXUS. The motor is 350watt nominally rated with a 12 magnet cadence sensor and throttle.The max speed is 20mph, so with that throttle and pedal assist, that makes this a Class 2 ebike.

      The bike really shines as a last mile vehicle, great for little hops across the way and getting in and out of transportation like buses, trains, subways, etc. The ability to sit with it, store it, and walk with it are great. And it looks good too!
