Default NuVinci installation on a Micargi cruiser

Step three - buy a pair of "torsion bars" from this website: Motorized Bicycles Detail Page, or else fabricate something similar (the first photo is from Staton's website). I've read several stories on other forums from people whose Nuvincis had torn up their rear dropouts. The Nuvinci definitely places a lot of torque on those drop-outs - relieve this stress by attaching one of these torsion bar on each side (basically an arm like on a coaster-brake). The pictures show how I cut and re-welded the bars to fit the "diagonal" drop-outs on the Micargi cruiser. If your drop-outs are horizontal (like the ones on a Felt bike for example), then you should be able to use Staton's torsion bars without much modification.
