Like a geometry teacher’s wet dream, the Strida Bike is a near perfect triangle shape.

Why? Well, it’s the latest attempt (by a British designer no less) to create a bike that’ll fold away neatly and be carried on the train or tube.

Mpora had a crack on one of these. It did take a bit of getting used to (there’s the odd issue of having a top tube that sticks up between your legs for starters!) but it actually worked surprisingly well. It also comes in a fetching beige.

Whether or not these will catch on is another matter. Maybe Triangle-obsessed indie darlings Alt-J could be persuaded to help with marketing?
