I had a 2006 model 18" Orange 5, the last model before they dropped the top tube. I'm 6'1", but with stumpy wee legs so the standover height of the 18" frame suited me better. I loved that bike, it really was very chuckable and great fun. However, I had to run it with most of the seat tube out of the frame. No prizes for guessing what happened last autumn then. 😥
Snapped clean through the seat tube / top tube junction. I was quite unhappy about that. However, I now have a shiny new 2010 Orange 5 frame in 20" flavour, with dropped top tube to fit my hobbit legs. My views have changed with it. The larger frame is far more confidence inspiring and just fits like a glove. I love my Orange 5, probably even more than my P7, or my Patriot that's sitting beside it. My previous bikes, a Gringo and an Orange O2 hardtail just pale in comparison. Mind you, I'm kinda fond of Oranges, so I might be a wee bit biased. 😉
You really need to try the two sizes out. I honestly thought my old Five was the best bike in the world….until I got my new Five. 😆
Happy shopping!
