LVBU Yunlun BZ Series: Transform Your Bike with a 3-Minute Conversion Kit and 180 km Range

  The emergence of electric assist bicycles has brought a dramatic transformation to the cycling world. However, the concept of electric assist bicycles has evolved differently in China compared to international markets. Due to high technical barriers and varying consumer needs, electric bicycles in China have increasingly morphed into what we now see as “electric scooters,” moving away from the pedal and traditional bicycle design to resemble electric motorcycles.

  Many people mistakenly believe that an assist bicycle is the same as an electric scooter. In reality, an electric assist bicycle is a traditional bicycle equipped with a power assistance system designed to make cycling easier. Positioned between a regular bicycle and a "pure electric vehicle," electric assist bicycles offer a mix of exercise and transportation with a combined drive system of electric power, pedal assist, and human effort. Today, we introduce the LVBU Yunlun BZ Series, a conversion kit that effortlessly transforms an ordinary bicycle into an electric assist bike with performance that rivals that of electric scooters. Let’s dive into the details!

Product features and configuration，The LVBU Yunlun BZ Series includes essential components such as a motor wheel, controller, battery, charger, and installation tools. The controller and battery box are mounted on the rear rack, with the controller positioned at the front of the rack and the battery box designed to be removable for easy charging. The battery comes with a lock to prevent accidental removal during rides. Additionally, the battery features an intelligent rear light that activates during turning and braking, ensuring safety during night rides.
The battery uses automotive-grade lithium-ion cells with a capacity of 36V17.4Ah, providing over 1000 charge cycles while retaining 75% of its capacity. It has a lifespan of up to 5-10 years and includes a high-performance Battery Management System (BMS) with six protection features: overcharge, over-discharge, over-current, short circuit, temperature, and load balancing, ensuring reliable and safe usage.

The kit features a 250W high-speed brushless motor that allows for pedal-assisted riding. The bicycle can be driven in three modes—human power, electric power, or a combination of both. The pedal assist mode is particularly popular, as it can extend the range of the bicycle by 2-3 times. With a range of up to 180 km, it is suitable for daily commutes and even long-distance rides, such as the Sichuan-Tibet route.

The LVBU Yunlun BZ Series includes a micro-assist system developed over 8 years, allowing riders to switch assist modes and ratios via a mobile app, greatly enhancing the riding experience. The high-speed motor ensures smooth operation with no resistance when the battery is depleted, offering a comfortable ride with minimal effort. When powered, the assist mode can be adjusted to match riding conditions, with five intelligent assist modes available: commuting, leisure, exercise, climbing, and manual. This provides a unique riding experience compared to electric vehicles.

As an assist conversion kit, the LVBU Yunlun BZ Series upgrades your bicycle to an electric assist bike, meeting the needs of daily commuting and fitness with a low entry barrier and broad appeal.
