My wife was convinced to take a look at a mini velo. It's so unpopular in the States, so it took some convincing. On her first day of trying it out, she was sold. She has a Brompton M3L, a Trek 7.4 FX hybrid, and Linus Dutchi; and she said love this bike the most. Her description of it is "zippy and solid", which sums it up pretty well.
And we decided to sell her Trekky and the Linus because the Mini-20 is able to meet both purposes, both recreation and utility.
Here is a review of it.
