Couple years back I got a Merlin Malt 1 for my wife, but in a size which fitted me - she is a good 3 inches taller without heels (even more with heels - but that is another story) but about 5 inches longer inside leg. And yes, I am taller than Cruise...bike too small.
However, just built up a Fisher GED frame for her after getting it powder-coated white. Middle and small chain rings only, 120mm travel Maz, carbon post, womens saddle, thin grips, Deore hydro brakes and decent wheels and tyres. And some nice anodized bits - in pink - skewers, grip clamps and a rather cheeky stem-cap and bolt from Purely Custom.com - check them out Bike is a bit on the heavy side, but fits perfectly - she seems to like it because it fits and looks good.
In reality, given a 2 year old daughter, whilst we may be able to get out on our own now and again (plan for short and not too technical), the heavier bike will serve as a handicap for missus when I'm carting junior around on the back of my old SS Clockwork..
If she ultimately decides she does not like, then I can use it myself or simply store in the garage for anyone who wants a go - it certainly won't break.
