I get the feeling this system requires a battery (it even mentions battery in the article), and most of the actual power comes from that. The question is, will the generator make enough power to get you moving if the battery is totally flat? I kinda feel like no, you&amp;#x27;d have to sit there and pedal it just to charge it up, and then it would move you a few feet. Or you&amp;#x27;re going to be pedaling really fast, and moving nowhere.</text><parent_chain><item><author>dhosek</author><text>I don’t know about you, but I pretty regularly have my chain derail on my bike (at least a few times per season).

It then delivers this energy to the rear wheel (or wheels) via cables strung inside or outside the frame of the bike, rather than sending it mechanically through a chain or belt. Excess energy created by pedaling is fed back into the battery. The end result is a power system with fewer moving parts to complicate construction.&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.theverge.com&amp;#x2F;2021&amp;#x2F;9&amp;#x2F;2&amp;#x2F;22653697&amp;#x2F;schaeffler-free-drive-e-bike-system-chainless&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.theverge.com&amp;#x2F;2021&amp;#x2F;9&amp;#x2F;2&amp;#x2F;22653697&amp;#x2F;schaeffler-free-d...&lt;/a&gt;</text></item></parent_chain></comment><story><title>Chainless electric drive system “Free Drive” for bicycles (2021)</title><url>https://www.schaeffler.de/en/news_media/press_releases/press_releases_detail.jsp?id=87716736</url></story>
