>>>>And the two folders offer the best protection against theft than any bike I had before. And I still ride the same hilly area that I covered with the road bikes with ease with the three speeds. I just carefully plan the chain-ring/cog ratio far more carefully at purchase for the terrain I use the bike on.<<<<
What combination of chain-ring/cog ratio do you use? If you drop to a 49 Direct drive (2nd gear), 1st gear will only take you to 36 or inches (or somewhere around there) which I consider high for hills. Just curious.
