I am just about to share your pain.  I bought a Double Up bike a month ago so I can take my loving wife with me on some rides.  I first bought a used Corbin seat for the Wife's comfort, then for Christmas I got her some gloves with the knuckle armor.  She has been talking to a freind of hers that rides and the woman loves her leather chaps.  So a helmet, jacket and chaps are all going to have to be purchased in the not too distant future.  If I expect her to ride in cold weather.....heated gear will also be a requirement!

Gotta make the wife as safe and comfortable if I expect her to enjoy riding with me.

It is not inexpensive. I just went through outfitting the wife with all the gear in the early fall. I really hawk the closeout sites and was able to pick up an armored mesh Shift jacket in bright red for about $60, a Bell Vortex full face helmet for $90, and a pair of leather lined Tour Master (Cortex?) jeans for $90. The gloves we bought retail from the local dealer. She already had a sturdy pair of leather boots.

What was missing was the radio. She really likes to have background music at all times. I can't imagine listening to music while piloting a bike. I would be helping with the drum solo on Winter's 'Frankenstein" and ride the thing right into a tree.

I picked up and ipod Shuffle for Christmas for $44 and loaded it with her favorite songs. The thing is about the size of a postage stamp, clips to the front of the jacket, and the ear buds fit well under the helmet. Problem solved.

Good hunting
