At the recently held 2025 China International Bicycle Exhibition, Luofandi, a core supplier of intelligent short - distance travel, showcased its latest product series - iGearbox at the exhibition. The product is centered around "intelligent electronic control + automatic transmission", aiming to promote the transition of EBikes from "mechanical manual transmission" to "intelligent automatic transmission".
In the actual use of traditional transmissions in Ebikes, there are many pain points. For example, there is a stutter when starting in a high gear, and maintaining a high gear after parking results in extremely high starting resistance, requiring users to manually adjust multiple times to start. In uphill scenarios, the gear cannot be automatically downshifted, leading to an unsmooth riding experience.
The core breakthrough of the Luofandi iGearbox series lies in its self - developed DynaSync intelligent automatic shifting technology, which can effectively solve the above problems. This technology constructs a three - layer collaborative system of sensing, decision - making, and execution, capable of collecting real - time key data such as cadence, torque, slope, and speed during riding. Through an advanced AI dynamic learning algorithm, it conducts a precise analysis of the riding state and can automatically match the most suitable gear within 0.2 seconds of prediction.
Specifically, this product has a dual - speed shifting mode. In the automatic intelligent shifting mode, the shifting operation is completely entrusted to the system. Users can also choose personalized control, supporting manual shifting via Bluetooth finger shifters and being compatible with riding apps. They can preset parameters according to different scenarios to create their own personalized riding experience. Whether it's the need for strong torque when climbing hills, special considerations for power output under heavy loads, or frequent shifting requirements on complex road conditions, it can handle them smoothly, ensuring continuous power output and overcoming the problem of easy failure of traditional transmissions during high - load shifting. The iGearbox can automatically complete more than 20 shifts per kilometer, allowing users to focus solely on riding and enjoy the fun of cycling.
Supported by its self - developed DynaSync intelligent automatic shifting technology, Luofandi has launched three types of transmission products. Among them, the R900, jointly developed with the leading electric drive listed company Annada, integrates the motor unit, three - speed shifting module, and electronic control system in a deep - integrated manner. Designed for hub - motor Ebikes, it has a transmission efficiency of over 95% and weighs only 3.9 kg. When paired with a belt drive, it can reduce maintenance costs by 30%. This design gives vehicle manufacturers more flexibility in body structure layout, reduces the complexity of wiring harnesses, and effectively improves system reliability. At the exhibition site, Luofandi also displayed its mid - drive 7 - speed intelligent internal transmission, with a total speed ratio of 435%, suitable for high - end mountain Ebikes. Its fully sealed structure enables lifetime maintenance - free operation.
Equipping mid - drive motors is in line with the development trend of the Ebike industry. Mid - drive motors are usually installed at the bottom bracket position, making the vehicle's center of gravity lower and more concentrated in the middle of the body. Compared with hub motors, they have stronger power, better handling stability, can optimize the motor's output power, and their concealed installation position results in lower maintenance costs.
In Germany, an important market for Ebikes, the installation volumes of mid - drive motors and hub motors are evenly split. eMTBs and eCargos also mostly use mid - drive motors due to their requirements for high horsepower and high - power functions.
Currently, while focusing on technology research and development and product innovation, Luofandi also adheres to an open and cooperative attitude. It can customize shifting logic according to customer needs, such as developing special parameters for special - purpose vehicles like off - road and cargo - carrying models, and jointly creating differentiated products.
