Looking for some quick advice. I just ordered a Brompton (M6R), 6 speed(standard). I only have a few days to make changes before the order is submitted. I initially was going with the 3 speed but changed it to a 6 speed after spending the night on the internet(still not sure). I am wondering if the 3 speed would be enough. I live in a suburb of Boston, and don't plan on doing any long distance travel. Mostly local roads and bike paths etc. How does the shifting work on the 6 speed? Can you shift 1-3 without going into 2nd or are you required to go up/down the gears?.. Thanks in advance..Joe
