Would appreciate some guidance on selection of a replacement front single crankset. I am 6'2" tall, would like 175 mm cranks, possibly a larger diameter crankset. In my initial shakedown ride, I had no difficulty on a 7% grade with the stock 6-speed freewheel. With the added leverage of the longer cranks, I am trying to decide if 52T might be a bit too ambitious, go with something more like 48T. No interest in adding a FD, double chain rings.
Recommendations of specific models would also be appreciated, Dahon-related forums are not very helpful.

If I am going to upgrade the crankset, would it be wise to upgrade the BB as well, or simply do a good job lubricating the bearings?
