I have bought a few new bikes without testing or even seeing in real life.
Giant Trance
Orange 5
Saracen Ariel
The only bike I didn’t get on with was the Ariel, not the bikes fault. It was a really sorted bike, well built and a nice spec. Despite researching geometry and comparing the numbers it just didn’t feel right.
The only reason I take a punt on an unseen bike is because I have been able to buy them super cheap. That way If I don’t get on with them I can sell and not loose much. I sold the Ariel a couple of months ago for £50 less than I bought it for.
I recently bought a Zesty, went to see one in person though. Very happy. When it doesn’t work out it’s a pain to do the selling/buying thing.
Hope your new bike is what you want 🙂
