The Ecotric Dolphin is an upgraded electric bike that offers a range of enhanced features and benefits, making it a reliable and convenient transportation option. Here are the key details about the Ecotric Dolphin:


The original LED display has been replaced with an LCD display, providing users with a user-friendly interface to operate the bike. This display offers real-time information about speed, battery power, and mileage. Additionally, it allows for direct control of the bike's lighting system, making it easier to use, especially in low-light conditions.


The Ecotric Dolphin is equipped with a high-powered 500 Watt brushless geared motor. This motor not only increases the bike's performance but also extends its lifespan by reducing friction resistance. This reduction in maintenance requirements saves time and ensures a consistent riding experience. The 20" * 4.0 tires with anti-skidding properties make this bike suitable for various terrains, including snow and sand.


The bike features a large 36V/12.5AH removable battery. This design allows for convenient charging at home or the workplace and also serves as an anti-theft measure. The battery is equipped with waterproof functionality and over-charge protection, ensuring safety and durability.


The Ecotric Dolphin offers versatility with four distinct working modes:

  • Pedal Assist Mode: The motor provides a moderate amount of assistance as you pedal.
  • Fully Electric Mode: You can engage the motor with a twist of the throttle at any power level you desire.
  • Pedal Mode: You can use the bike just like a regular bicycle, pedaling without electric assistance.
  • Booster Mode: This mode allows the e-bike to travel at 6km/h (3.73 miles/h), making it easy to maneuver and push when needed.

UL Certified:

The Ecotric Dolphin boasts UL certification, ensuring that the product has been rigorously tested to meet safety standards. This certification adds a level of credibility to the bike's safety and quality, setting it apart in a competitive marketplace.

Warranty and Additional Features:

Each Ecotric Dolphin comes with an 18-month warranty covering manufacturing defects in materials or workmanship on its frame, battery, motor, controller, and display. The bike also includes a set of fenders to protect your clothing from mud and water, enhancing the overall riding experience.

In summary, the Ecotric Dolphin is a highly capable and feature-rich electric bike that combines power, convenience, and safety. It offers a range of working modes to suit different riding preferences and comes with the assurance of UL certification and an 18-month warranty, making it a reliable choice for eco-friendly transportation.
