While we probably wouldn’t call the projects of most custom bike builders tame, per se, there are plenty of absolutely bonkers ideas most of builders wouldn’t touch with a ten foot pole — like strapping a seat and two wheels onto a car engine. Of course, that leaves room for the odd project that breaks all traditional boundaries and leaves onlookers completely drop-jawed, like the ‘Gangrene’ rat bike you see before you.
As you might imagine, this apocalyptic hodgepodge isn’t actually made by a custom shop, it was built as a personal project by a Russian man, Artem Boldyrev, out of Yekaterinburg. Inspired by a similar project from the United States, the two-wheeler was built around the monstrous engine — a Lexus V8 with an overwhelming 300 horsepower and an automatic transmission. To cope with all that power while keeping it under three meters in length (ensuring it would remain street-legal), it also required a massive rear wheel mated to a two-chain torque system fed through the front gearbox from an all-wheel drive Toyota Mark II Blit. The big bike also received a specially-made gas tank to ensure it would travel long distances and Boldyrev even made a matching Fallout-inspired helmet to complete the wasteland look of this insane Franken-bike.
