Checking out small wheeled bicycles

I have been having thoughts of replacing my road bike with 700cc wheels with a folding bicycle or mini velo with 20inch wheels. I went around the Marina Reservoir area on Saturday using a Giant mini velo and a Strida. I believe the mini velo had 20inch wheels while the Strida had 16inch wheels.

I cycled approximately 11+km on each bicycle to get a feel of the bicycles.

Starting things off with the Giant Escape Mini which was a 7 speed bike, I cycled towards the Gardens by the Bay. The route was mostly flat, but I found myself struggling a little. Perhaps I was too used to having toeclips on my own bike.
