I didn't know I needed choo-choo train noises in my bicycles but I do! You can use this for anything, a choo-choo garage door opener, a choo-choo elevator, a choo-choo plane!
Gotta hand it to Phineas T. Freakears. I thought the energy density would be terrible but it's roughly comparable to lead acid/DC motor!!! Which is still way heavy for a ten speed but hey if you don't mind that whopping steam engine tank on the back you're golden.
Maybe he can get the same running time as an equivalent weight electric drive, which I seriously doubt, but the inefficiency of his fuel source (an air compressor) totally rapes the overall efficiency of the system.
If you had ass-dreads long enough to try and convert a regular bicycle into a powered one, you'd be way better off getting a custom li-ion cell made.
i know it says prototype, but i'm losing my shit over putting in that much effort and winding up with free-spinning pedals and the hazardous riding posture to go with it
Stuff like this triggers me as well. As a kooky "Hey guys, Portland" project, it's whatever... but he had to throw in the quip about oil spills and start a gofundme.
