While this no-weld rail bike conversion looks like it would be unsafe at any speed, it does look like a ton of fun (isn’t that always the case?). There are miles and miles of unused tracks that carve their way through America’s backcountry that have yet to be converted to bike trails. Something like this could make these hidden corridors and seldom used easements instantly accessible to folks crazy enough to attempt riding it. [via BikeHacks]
