I used to have a Tikit and a Brompton. After a few months of head-to-head comparison, the Brompton also won out. I just found that I preferred to take the Brompton wherever I went because of the small package. The M6L rides very nicely for its intended purpose. And even though the Tikit might have an edge in "sportiness", I concluded that I didn't need that for city riding. So, it now belongs to a guy who does a long commute everyday via train.

Have fun with your Brompton, and hope the wait is not too long...
