Kolelinia has put forth a radical concept in bike lanes – the high wire! Made up of a small channel for your wheels and handlebar cable guides that keep you on track, the Kolelinia concept is intended to ferry cyclists over trouble spots or areas where traditional bike lanes aren’t practical.
Yeah, the technical aspects of keeping your wheel perfectly straight in such a design (among other things) are not fully fleshed out (although you could just let go of the handlebar and let the channel guide the bike while you sit up and pedal), there was a laudable amount of thought put into the handlebar guide design. Pics below, and there’s video on their website. And if you fall? Well, first, don’t fall. But if you do, there’s a safety tether to keep you from actually hitting the ground.
