I love the idea of the Brompton, but in reality I don't find my Brompton much fun to ride. If I didn't need to tuck it into crowded subway trains, I would ride just about any other bike but the Brompton. I also have a Dahon Mu P8, which I find much more enjoyable to ride. Unfortunately, the clumsy fold and the exposed chains make it less than ideal for multimodal commute.

Many people love their Bromptons and have no issues with the ride. But there are also those who, like me, feel hampered by its ride quality. So I would suggest taking stock of your needs, and especially going on multiple test rides to see which fits your needs better.
