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, 12AH 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®!

This is the second folding fat tire bike we have purchased from Ecotric . The first one was a pleasure to ride on sand gravel or snow, they are easy to peddle in all conditions .Now my spouse and I can ride together on our camping trips .I have told all my friends they should buy one .

Much better

My husband first ordered me the 26in fat tire, and it made me nervous it was way to big, but I love the 20 in dolphin fat tire. It's the perfect size for me

This feels like a sturdy has taken me a pretty long time to assemble it but that is because I am not as young as I used to be. Pretty sure anyone would be happy with this bike. If you are unfamiliar with assembling things like this you may want a professional to look it over before riding just to be extra cautious. The YouTube video is extremely helpful for assembly instructions. Just take your time and be patient with the process. You may want to get a smaller wrench than what is provided because some of the things that need tightening etc are too small for that one.

My husband loves his new bike. We are once again enjoying biking. Great bike for seniors too.
