Hi Arved,
I wanted to share a project from 2007 built with a Toxy ZR. This was a project at Western Washington University in Bellingham, WA, USA. The "Valkyrie" recieved two grants and 4 awards at 3 intercollegiate competitions in 2007 in California, Oregon, and Nevada. Top speed on flat ground: 52.9mph (85 km/hr). Thank you for the great bicycle!
