Motorbike Garage Mechanic Simulator is a game that simulates everything about being a bike mechanic. Disassemble, repair and build bikes, order spare parts (even hunt down bargains), all with an explicit attention to detail. The motorbikes in the game all have 260 interchangeable parts, with over 600 choices in parts to choose from. You can repair someone else's bike or build your own from the screws up.
Our reviewer Aron Gerencser was impressed, calling Motorbike Garage Mechanic Simulator "polished and incredibly detailed, and manages to be enjoyable even for non-enthusiasts... entertaining and relaxing". High praise indeed.
