Geared Mid-Drive Technology:

Some History: The geared Mid-Drive technology has been around for a long time. The earliest brand to use mid-drive was Flyer in Switzerland with great success. Generally mid-drive technology was considered “restrictive” and in-elegant. It was noisy and restricted to 250W. Flyer had great success in Switzerland but limited success in the rest of Europe. Panasonic manufactured these drives. They were generally considered a strong workhorse. Since the explosion of the market in 2011, Flyer has diversified to add a number of other mid-drive options and models. Their web-site can be seen here: https://www.flyer-bikes.com/.

In 2011, Bosch launched a mid-drive system in partnership with a number of German bike manufacturers. The system was an instant hit. The “hit” was primarily because of the fact that German bike manufacturers were starving for a system which could be well supported locally. With Bosch service centers and technicians all across Germany, the mid-drive became “The eBike System” and German customers were quite happy. Another big push came when Haibike launched a mountain bike with Bosch system. The performance was great because the weight was concentrated in the center of the bike. Those two events practically gave a tremendous boost to Mid-Drive platform.
