Vivax is back in the news with reports from the Italian press that a masters racer was caught by officials with a motor in his bike. Google Translate this article and it reads like a script treatment for Tour de Pharmacy Part Deux, Motor Doping.
The Vivax system is a valid, enabling tech for a variety of reasons; including an assist up hills for cyclists with degenerative diseases. It’s precision manufacturing and bottom-bracket based design also means handbuilt bike makers can build one too with materials like steel and titanium.
I know this because Bill Davidson is making Vivax bikes in Fremont at DKCB. As long as a Vivax bike isn’t showing up to race at a sanctioned event, I think they’re great and hopefully a toxic roadie topic can get redirected to how it’s helping cyclists who can use it.
