I've been using some spiky BMX pedals lately, and I really like them:


Compared to clipless, I like being able to move my feet around, not being forced to carry a second pair of shoes, and I don't see any loss in efficiency

Compared to toe straps, I get rid of the stupid strap, which is mostly just a hassle, and get a bigger platform.

Compared to my previous flat pedals (MKS RMX from Rivendell), the spikes grip so much better, they feel much more secure.
