I'm six feet tall as well , and I got the Alley Cat from Eddie . Perfect . 16" is too short . Go with the 18" , 20" just looks too obtrusive IMHO .

2005 Model . Two Fast Eddy stickers , a bell and a clock . She's Lola . She tinkles and keeps time . http://s649.photobucket.com/albums/uu211/britbike05/
