Ventus, a homebuilt based on Steelmachine Mk.1. Rear fork from Favorit road bike (28"), 40×40 mm boom. Unlike my slightly twitchy Tractor with tiller handlebars, this bike is totally stable and calm, you don't need more than two fingers to steer it. Bottom bracket is high enough to completely eliminate heel strike, but there is knee strike with the handlebars - pedaling in sharp turns is equally problematic on both bikes, just for different reasons.
