There is no front derailleur. I normally stick with one gear range for a ride, but it is not difficult to move the chain when stopped.
I should think about that. On my folder I have a Sram Dual Drive with an eight speed cassette for 24 speeds, I used the Dual Drive because I can't fit a front derailleur. Before I got the Dual Drive, I tried a double crank but got tired of having a greasy finger to manually change gears, so I went back to a single when I bought the Dual Drive. But there have been a few times I wished I had wider gearing. I have a derailleur cage long enough that I could fit that double crank again.
