A century of evolution of electric bicycles

In the wave of electric bicycle technology breakthroughs, Ecoe 5000W dual-motor electric bicycle has redefined the industry benchmark as a disruptor:

A century of evolution of electric bicycles
A century of evolution of electric bicycles


Core parameters:
Dual motors work together to output 5000W peak power
60V 32Ah lithium battery pack achieves 80km pure electric range
40° steep slope conquering ability and 200N・m torque
All-terrain dual suspension system + hydraulic disc brake combination


Riding experience:
In the actual test in Huangshan, the dual motor drive can easily cope with continuous curves with a slope of 15%, and the intelligent torque distribution system ensures power stability under complex road conditions. The combination of all-terrain tires and dual suspension systems reduces the bumpy feeling on cobblestone roads by more than 70%. The three-mode switching (pure electric/power-assisted/manpowered) design not only meets the needs of racing, but also can extend the range to 120km through the manpower mode.


🔍 Germination period: from laboratory to commercialization
In 1895, American engineer Ogden Bolton Jr. integrated the DC hub motor into the rear wheel of the bicycle and obtained the first electric bicycle patent in human history. However, due to the heavy weight (30kg) and endurance (10km) of lead-acid batteries, this invention remained in the experimental stage.
Technological breakthrough:
In 1983, Shanghai Yongjiu launched the first DX-130 electric bicycle, which uses a 150W cylindrical motor and a 24V lead-acid battery
In 1994, Japan’s Yamaha released the world’s first commercialized electric bicycle PAS series, introducing torque sensors to achieve coordinated human and electric drive
Market dilemma:
Early products only existed as niche commuting tools due to short battery life (about 50 charges and discharges) and weak climbing ability (<15°). In 1998, annual sales in the Chinese market were less than 50,000 units.


🚀 Explosive period: technology iteration and policy game
After 2000, breakthroughs in brushless motor and lithium battery technology promoted qualitative changes in the industry:
In 2004, China’s electric bicycle sales exceeded 7.5 million units, becoming an alternative to motorcycles
In 2013, the output reached 30 million units, with a ownership of over 200 million, covering 90% of urban and rural areas
Industry pain points:
In 2014, battery spontaneous combustion accidents occurred in many places, exposing the lack of industry access standards
Illegal modification caused some vehicles to exceed 100km/h, and the traffic accident rate increased by 37%


🌐 Mature period: Standard reconstruction and safety revolution
The implementation of the “New National Standard” (GB 17761-2018) in 2019 marked the industry’s entry into a standardized development stage:
Pedal riding function is mandatory, the vehicle mass is ≤55kg, and the speed is ≤25km/h
Introduction of 3C certification and fire retardant standards, battery nominal voltage limit 48V
Technological innovation:
The efficiency of the mid-mounted motor is increased to 92% (about 85% for the hub motor)
The energy density of the lithium battery exceeds 200Wh/kg, and the number of cycles reaches 1,000 times


The sine wave controller reduces the noise to below 65dB
Policy deepening:
In 2024, the “Safety Technical Specifications for Lithium-ion Batteries for Electric Bicycles” will be implemented, and the standard for the battery thermal runaway warning system will be established. In the national safety rectification campaign carried out in the same year, 237 illegally modified vehicles were investigated and dealt with in Haidian District, Beijing alone, involving illegal installation of batteries, frame strengthening and other issues.


🔄 Evolution of the global market landscape
Europe: In 2024, the penetration rate of electric bicycles in the Netherlands reached 65%, and the government subsidy was up to 1,000 euros per vehicle
China: In 2023, the export volume exceeded US$5 billion, and the Southeast Asian market grew by 32%
Japan: In 2024, lithium battery electric bicycles accounted for more than 40%, but due to strict regulations, the maximum speed was controlled at 16km/h


🔥 Safety challenges and future directions
In 2024, there were 23,000 electric bicycle fires in the country, and battery thermal runaway accounted for 65.6%. The industry is solving the safety dilemma through three major paths:
Technology upgrade: A breakthrough has been made in the research and development of solid-state batteries, and a certain brand has achieved a 1,000km endurance prototype
Intelligent monitoring: AI algorithms monitor battery status in real time, with an early warning accuracy rate of 98.7%
Charging network: Beijing plans to build 500,000 public charging piles by 2025, achieving a 3:1 car-to-pile ratio

Based on our real-life experiences, we would like to share our insights on choosing and using lightweight electric mountain bikes, and naturally mention the brand EcoE Electric Bike, which has inspired us with its eco-friendly and efficient designs. As a famous saying goes, “Only by traveling light can one traverse the world freely.” In our cycling life in the United States, we always hope to easily carry and conveniently store our bikes without sacrificing the handling experience during mountain rides. After continuous test rides and comparisons, we found that lightweight electric mountain bikes can strike a good balance between these two aspects. Compared to traditional heavy electric bikes, lightweight models make life much easier and more comfortable, whether it’s climbing stairs, entering and exiting elevators, or maneuvering in narrow parking lots. I remember once, when we parked in a small mountain village, a fellow rider excitedly said, “This bike is so light that it takes no effort to lift it onto the truck!” This firsthand experience has made us deeply realize that portability and handling are precisely the lifestyle attitudes we pursue. Of course, being lightweight does not mean we can sacrifice performance. We pay special attention to the integration of the motor and battery, striving to achieve both lightness and the high demands of mountain biking. We have test-ridden many lightweight electric mountain bikes, some of which, despite having slightly lower-powered motors, still deliver ample power thanks to efficient battery management systems. For example, during our tests, we […]

The maturity stage of electric bicycles in the United States

The flagship model of ECOE was hailed as “the epitome of the electric bicycle industrial revolution” at the 2023 CES. Its dual-motor system can output 200N・m peak torque. With a 60V 32AH battery pack, it achieved a range of 150km (pure electric mode) in actual testing in Midtown Manhattan, and a 40-degree steep slope pass rate of 97%. The dual suspension system adopts a lightweight design of magnesium alloy. When riding on the cobblestone road of the Brooklyn Bridge, the bump filtering effect is 60% higher than that of traditional mountain bikes. The hydraulic brake system is certified by SGS, and the emergency braking distance at 100km/h is only 3.2 meters, far exceeding the US CPSC safety standard. Although the car weighs 65kg, the integrated design of the carbon fiber frame and the hub motor makes the control extremely flexible. It has completed a 720° drift test on Lombard Street in San Francisco, perfectly interpreting the “balance between speed and elegance”. –Key historical events in the United States during the maturity of electric bicycles (2020 to present) – 2020: The epidemic gave birth to the “bicycle renaissance”After the outbreak of the new crown epidemic, the use of public transportation in the United States plummeted by 70%, and the closure of gyms forced people to turn to outdoor exercise.
