Thought I'd post some of the 'WHY'S' here just to demonstrate that its not completely frivolous and that there was some kind of ratonale behind all this - even if that rationale doesn't apply to anyone else.
One of these bikes goes to Viv, who's coming up to 20. In Colombia spandex on solo riders isn't as common as it is here and chances she'll wear it for anything short of a full day outing in company are zero. So she gets a Selle Italia Diva Gel - it'll save her bottom. And since she's continuously been one of the top students in her school - I'm more than OK with that.
The Ergon pedals will let her use any shoes she wants to. BMX pedals with screws would work equally as well but those same screws can accidentally make some interesting marks on the backs of legs. These are legs that as yet don't have a mark on them. Lets not change that. The Ergon bar ends will let het take a more agressive stance if she wants to push things a bit. The lock on the bars is a reminder that its her bike not mine - and her responsibility. The pink cables and bar tape is a personal touch that'll also eliminate any chance her brother might want to borrow it

He can use mine - it'll be built to take more abuse.
Fanny is 55 and has type 2 diabetes. The lower gearing of the RaceFace XC crankset will put everything within her reach (there are some interisting hills in Cali) and she likes pink anyway, and the GP5's will give more hand positions for better circulation in her hands. The saddle, lock and pedal choice for the same reason as for Viv. The Shimano Pro Storage Bottle and Shimano Pro AeroFurel Triathlon TopTube Bag will give her someplace to store any essentials for her diabetes and likely a battery for lights. The wider tires give better braking and a more comfortable ride.
The third animal is getting a complete Hone groupset and a beefed up wheelset as well as most of the other changes. Partly because I expect Carlos to borrow it ocassionally and partly because I'm considering outfitting it with Thule Pack 'N Pedal racks (formerly Freeload) That one could take a while because I'll be converting the front axle from QR to solid, have to special order spokes, and there'll probably be shipping delays.
Maybe someone already makes something like this ready to roll - I just haven't seen it myself.
