Pignon 48 dents pour vélo - filetage standard France

thingiverse

Hello, I'm working on building a quad bike from two BTwin bikes, one of which belongs to my son and the other was found on the street. I needed a significant gear ratio for the multiplication from an electric motor (also an 8-tooth gear on my page). Not finding it, I designed and printed it in 3D. Photos of the finished quad bike will come later. On April 7th, 2018: modification with a wider bushing and beefed up the thread area... otherwise it would have broken.
