You generally want to sell things that are sought after and have high demand not only by the AH players but also the casual players who only play for fun. Some of the best and quickest spinning markets are buff-foods, potions, flasks and of course aything JC or crafting related. These are the items that are needed to all raids, dungeons, pvp and professions. You can go ahead and craft 100 end-game patterns or choppers or anything like that but you'll be lucky if you can find some very few people who are in the need of that certain item right now.
Of course you can make huge profit with every market if you play it smart but what you're doing is basically playing together with other AH players, flippers etc... If you put up a Cardinal Ruby for 5% less than the current cheapest one on the market, chances are it will get bought in 10 sec and 99,9% of the time its not bought by some fellow JC who needs to make himself some gems. It's bought by some dude sitting and scanning the AH 24/7 and whenever he sees a profit margin bigger than 0,5% he goes in for it.
Oh yeah and you also said it's impossible to farm the bike. Yes it is, and of course when it comes to investing you never want to hear the words "farm" or "grind". Then you're not investing, rahter farming. Anything that is hugely RNG and luck based is to be avoided as well, except some things like the darkmoon cards or milling and prospecting in general. When you invest 100k+ in Icethorns, mill them and make hunderds of darkmoon cards the RNG becomes a beautiful pattern that in huge quantities is highly profitable. Now that's an investment.
