I am in the market for a quality folding bike but have had many-many concerns about Dahon's products. I fell in love with a 6 speed M-style Brompton, but am concerned with the fact that I will be riding it on very hilly terrain in-and-around Los Angeles. I feel like 6 speeds won't be enough at times and haven't been able to get used to the shifting of gears when taking a Brompton for test rides.
Currently, I've gotten around L.A. and Pasadena's hilly terrain just fine with a both an early 70s 10 speed Fuji road bike and a mid 90s Jamis Earth Cruiser with a 7 speed internal hub.
However, reading this thread has had me reconsider Dahon's Mu line.
Any thoughts or recommendations are most appreciated!
