The Dolphin contains so much of our design philosophy: to make it easier for customers to carry. Equipped with comfortable but compact 20" x 4" tires, the Dolphin-MBL can be conveniently folded to store and transport the bike more easily.

But don't underestimate its performance: aluminum frame, 500W power motor, 12.5AH high-capacity lithium battery, front, and rear mechanical disc brake, LED smart display, everything you need. It can take on many tasks you would not expect from a portable&folding bike, such as hauls from the grocery store, challenging terrain, and rough roads without breaking a sweat. Explore new roads with ECOTRIC®!

What is a UL certification?

UL stands for Underwriter Laboratories, a third-party certification company that's been around for over a century. UL was founded in 1894 in Chicago. They certify products with the aim to make the world a safer place for both workers and consumers.

This Standard offers electrical and fire safety certification by examining the electrical drive train system, battery system and charger system combinations. UL 2849 covers: E-bikes (typically sit-to-operate and over-the-road use) and pedelec (pedal assisted electric) cycles.
