Admittedly, I’m not sure how popular cycling will be once the (inevitable) Zombie Apocalypse arrives, but this is one Russian cyclist who will be prepared.
Motorists won’t mess with you. Pedestrians won’t step in front of you. It looks like the chainsaw on this Russian rig spins the front wheel so you won’t even have to do much pedaling. I suppose the designer could have taken the chain off the chainsaw and still used the engine, but that would have taken a lot of the danger/fun out of it.
