This weeks “Japanese Bicycle of the Week” is a 3 speed Maruishi bicycle
with drive shaft. This model uses a unique drive shaft system instead of a traditional chain and derailleur setup. This unique system transmits power from the pedals to the rear wheel. However, different models came with various speed options. For example, some have single-speed setups, while others offer multiple speeds like 3-speed or 7-speed configurations.
Maruishi Cycle Ltd. is a prestigious bicycle manufacturer perhaps best-known today for its vintage models. In fact, until late in the 20th century their model lineup also included penny farthings. To this day, Maruishi continues to make fine touring bikes in Japan.
Maruishi Bicycle Known For It’s Drive Shaft Systems
Drive shafts on bikes replace chains to transfer pedal power to the rear wheel. They use a solid shaft instead of a chain and derailleur. This setup aims to reduce maintenance and offer cleaner operation. Additionally, drive shaft systems provide smoother power transfer. However, they can make bikes heavier and more complex. While, they’re not as widespread as chain-driven bikes they do exist in specialized models.
This particular Maruishi model has a hub-powered front light which is connected directly to the dynamo hub. The dynamo hub is a device that generates electricity as the wheel spins. This type of light doesn’t rely on batteries but instead, it draws power from the dynamo as you pedal.
This provides a continuous source of light. Hub-powered lights are known for their reliability and constant illumination. For this reason, it makes them a popular choice for cyclists who regularly ride in low-light conditions. Furthermore, they’re efficient and eliminate the need for battery replacements, as long as the dynamo is functioning properly.
This Maruishi Had A Vintage Thumb Shifter
In the very early days of thumb shifters on bicycles, they were often basic and straightforward. They typically had a simple design, allowing riders to shift between a few gears using a thumb-operated lever. In fact, these early models focused on functionality rather than the multitude of gear options available in modern systems. Specifically, their primary goal was to offer basic gear changes for a more comfortable riding experience.
