Think about these patents the next time you read an advertisement about a new E-bike product that is...

This next E-bike was something that I wasn’t sure I should include, but this article is only about having a fun read, so…here goes: It’s from 1975, and it is patent No. 3884317 , filed by Augustus B. Kinzel. It mounts the motor around the BB-spindle. I can only assume that any production model would use the bikes gears on the rear wheel, so I don’t know why that wasn’t included in the patent. 10-speed derailleurs were common in 1975 (five sprockets on the rear wheel), and such a feature would have made this the earliest example I could find of an E-bike that gives the motor the use of some gears to improve hill-climbing. And yet…it is not specified in the text of the patent.
