The video’s a bit hokey, but get the benefits of the design in the first and last 40 seconds if you’re crunched for time.
Industrial Designer Ronen Spector, who has several interesting bike mockups on his website, created the SPiNe bike with a flexible lock as the top tube. When locked around a pole, the bike is unrideable. Put it back in place and tighten it down and you have a perfectly functional commuter.
We know, we know, try to cut the lock and the bike’s toast, but we’re guessing the confusing appearance would thwart would be thieves. And as always, it’s just plain neat to see different approaches to problem solving.
