Radiator Bicycle

Based on the comments, its from an antique and curiosity shop in Netherlands. Here's a Google Street view of the same spot - https://maps.google.com/maps?q=1e+Wormenseweg+109+7331+DD+Apeldoorn&hl=en&ll=52.203366,5.969417&spn=0.001126,0.002599&sll=37.0625,-95.677068&sspn=47.349227,85.166016&hnear=1e+Wormenseweg+109,+7331+DD+Apeldoorn+Zuid,+Apeldoorn,+Gelderland,+The+Netherlands&t=m&z=19&layer=c&cbll=52.203468,5.969414&panoid=ql4yZZpGWd1kvKqIhyvkDA&cbp=12,122.48,,1,16.08 . The Street View is dated July 2009 and the place is "For Rent", so it looks like the shop started after that point. They put in new bricks for the driveway, but the pattern for the sidewalk bricks hasn't changed, and neither has the downspout. And in the Google Street view you can see that there's no radiator there.

Yeah, who'd put a radiator outside?

It's a Sparta bicycle chopped at the Sparta factory as a prank gift. (Just checked with my co-workers there)
