Introducing Qualibike’s Dolphin: a powerful, long-range, and foldable electric bike. The Dolphin features a 14Ah Samsung battery, hidden in the seat post battery system, which is long-lasting, efficient, and encased with full battery-cell protection sleeve.
This e-bike will allow you to ride more than 50 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 to easily fit in a car trunk or under a desk. It can conveniently fold down into 32.6 x18.9 x 27.5 inch, which means it can be easily stored in tight out of the way places in your home, under your work desk, or on public transport. Additionally, weighing only 23kg, the Dolphin is a fantastic portable e-bike for urban commuters or students looking for a faster and more cost-efficient way of getting around.
