UL Certified - Ecotric black Portable and folding fat bike model Dolphin


Easier To Carry

Look at the fat tires and the perfect curves. It is just like dolphins, which are chubby and cute but flexible. It has a 500W power motor, a 12AH high-capacity lithium battery, and its upper tube and handlebar are foldable. In addition, fat 20-inch tires provide good shock absorption. All this means this is a portable e-bike that you can ride for a long time on any road. And I couldn't come up with any other better options.

Why do I choose ECOTRIC UL Certified ebikes?

UL has been around for 125 years ensuring the safety and accountability of electrical products in everyday American life. Being UL certified illustrates a businesses’ dedication to consumer safety, as well as the quality of their products. Another important caveat of UL certification is for insurance purposes and customer security. It’s a true indication of an item’s safety and longevity.

Is The Bike Waterproof? Riding the bike in moderate or light rain is no problem, please make sure the bike is bone dry before the next riding, or the bike will cut off randomly. But do not park the bike in rain and never wade in the water. The battery and controller have a self-protection program. They will cut the power if there is a short. But water damage will destroy the electricity of the bike.
