250W Standard E-Bike Motors
-- Stadig och pålitlig tillverkare --
Defining the Urban Commute: The 250W Standard
In the global electric bicycle market, the 250W standard e-bike motor represents the most critical specification for legal compliance and urban efficiency. This power level is the internationally recognized threshold for "pedelecs" in the European Union (EN15194), the United Kingdom, and many parts of Asia. As a specialized manufacturer with 30 years of history, HENTACH—formerly known as Hengtai Motor—has been at the forefront of the 250W revolution. We understand that a successful 250W motor isn't just about output; it's about efficiency, weight, and the "feel" of the power delivery. Within our 9,000sqm manufacturing campus, we have dedicated entire production lines to perfecting this standard, ensuring that every unit delivers a natural, intuitive riding experience that turns a daily commute into a effortless journey.
The design of a 250W motor requires a focus on "Lightweight Strength." By utilizing our in-house 500-ton die-casting machines, we produce motor housings from specialized aluminum-magnesium alloys that minimize the weight penalty on the bike while maximizing thermal dissipation. Every gram saved on the motor allows for a larger battery or a lighter overall frame, which is the primary selling point for the modern urban cyclist. Our precision CNC machine tools ensure that the internal rotor-stator gap is minimized, which is the key to achieving the high efficiency (over 85%) needed to squeeze every possible kilometer out of a standard 36V battery pack. This level of manufacturing control is why our 250W units are the preferred choice for major e-bike brands globally.
Reliability is non-negotiable for the daily commuter. A 250W motor must be able to perform in rain, snow, and summer heat without fail. We apply our rigorous ISO 9001 quality control system to every stage of production, including a specialized micro-arc oxidation coating that protects the housing against road salt and moisture. Historically, our commitment to durability was proven when we tested 50 of our motors to the 50,000-mile mark. This longevity ensures that B2B partners can offer extended warranties with confidence, knowing that the "HENTACH" heart of their bicycle is built to last. Our legacy of 30 years in electromechanical innovation is distilled into every 250W motor we ship, providing a reliable, legal, and efficient solution for the world's cities.

Urban and Shared Mobility Applications
Our 250W motors are the "gold standard" for City and Commuter E-bikes. These bikes are designed for the rider who wants a sweat-free trip to the office and a reliable way to navigate urban traffic. Because of their legal status, they are also the primary choice for Shared Bicycle Programs in major metropolitan areas. In these high-usage fleets, the motor's ability to withstand 24/7 exposure and frequent use is paramount. Our motors are built to handle the abuse of public sharing systems, offering a low total cost of ownership for fleet operators.
- Folding Electric Bikes for multi-modal urban transport.
- Step-through City Cruisers for casual recreation.
- Corporate E-bike Fleets for campus mobility.
- Electric Road Bikes where minimal weight and drag are essential.
- Delivery E-bikes for light urban courier services.
The Advantage of a 30-Year Heritage
The primary advantage of the HENTACH 250W motor is its Seamless Integration of power and pedaling. We don't just build a motor; we build a riding experience. By utilizing high-resolution internal sensors and our precision-processed internal gearsets, we ensure that the power comes in smoothly, without the "jerky" feel found in cheaper alternatives. This refinement is the result of 30 years of electromechanical feedback from riders across the globe. Our Patented Nylon-Steel Gears further enhance this by providing a ride that is exceptionally quiet, allowing the cyclist to enjoy the city environment without the distraction of motor noise.
Additionally, our manufacturing scale allows us to offer these premium features at a highly competitive price point for B2B partners. Because we handle everything from the 500-ton die-casting to the final micro-arc oxidation in-house, we eliminate the markups and quality variances associated with subcontracting. Our ISO 9001 certification and our history of motors exceeding 50,000 miles give your brand an immediate aura of reliability and trust. When you choose a 250W motor from HENTACH, you are choosing a component that has been refined through three decades of "Hengtai" excellence, ready to power the future of urban mobility.
