I do not use clips on my Stratus bike. However it is imperative to use clips on a tadpole trike. My TT Cruiser came with rat trap pedals. Not long after my foot got jared loose by a pot hole at low speed thankfully, and it his the crossbar. It didnt hurt much, but when I got back I put on a pair of clipless pedals I had. All trikes really should come with a lawyer sticker saying that the rider should use clipless pedals to avoid injury!!!!
