CarryMe Single Speed - 8" wheels, super portable.  Great for the MRT/buses and in between stations.  Very comfortable to cycle but for a short woman, it may not be very safe to use on road with buses / trucks whizzing past you.  If I were more confident using the road, then it won't be an issue :)Dahon 20" Ciao P8 - very lady like as it's a step through.  I use this mainly if I foresee using roads more.   Since a good bit heavier than the CarryMe, I generally use it around market and streets as it would be cumbersome to get it up a bus or train.  Heard that it's possible to roll but it wasn't successful when I tried rolling it.  It tilt over to one side.
