How is this possible.
You need a road bike, a mountain bike, a light touring bike, a heavy duty touring bike, a shopping bike, a pub bike, a folding bike, a commuting bike, a few rod braked roadsters for countryside pootles, you need a fixed wheel, a freewheel, a derailleur multispeed freewheel, and hub gears just in the interests of science and comparing different gear systems. You need caliper brakes (single and dual pivot, rod brakes, canti brakes, back-pedal brakes also in the interests of science so you can see how all these things work and you need spares of all the above just incase you have a problem. ANd I'm sure there is something I've forgotten.
