This is one of the craziest set of photos I’ve ever come across! Two lucky guys had the opportunity to ride their bikes in an empty hydroelectric power station before it was filled with water. According to one of the riders, the surface of the power station is very smooth and the entire power station is huge! This is no doubt one of the most awesome pseudo-velodromes ever. Epic!

You have to see the rest of the pictures — they’re really impressive! I so wish I could have been there to do the same.
