Whether you're commuting to work, running errands, or simply enjoying a leisurely ride, the Ecotric Dolphin has got you covered. Let's dive deeper into its remarkable features:

Sturdy Aluminum Frame

The foundation of any great electric bike is its frame, and the Ecotric Dolphin doesn't disappoint.

Additionally, the frame is ergonomically designed to provide a comfortable and stable riding experience. The sleek black finish not only adds a touch of sophistication but also enhances the frame's resistance to the elements, ensuring your bike looks as good as it performs for years to come.

Powerful 500W Motor

One of the standout features of the Ecotric Dolphin is its potent 500W power motor. This motor is engineered to deliver impressive performance while maintaining energy efficiency.

The responsive acceleration ensures you can keep up with traffic when necessary while also enjoying a smooth and quiet ride. Plus, the motor's low noise output won't disrupt your peaceful journey or disturb others around you.

High-Capacity 12AH Lithium Battery

What truly sets the Ecotric Dolphin apart from the competition is its high-capacity 12AH lithium battery. This cutting-edge power source offers an impressive range, allowing you to travel up to 35 miles on a single charge, depending on factors such as terrain and rider weight. Whether you're embarking on a long-distance adventure or using the bike for daily commuting, the extended range provided by the 12AH battery ensures you won't be left stranded.

Charging the battery is a breeze too. With a standard 110V outlet, you can fully charge the battery in just 6-8 hours.
