Riese & Muller have cleverly designed an aluminium frame with no hinges to weaken it. Instead of a folding frame, the front and back wheels fold in - and the same pivots which let them fold also provide very good front and rear suspension. The suspension also makes the Birdy very fast - you can run the tyres at 100psi+ yet still be comfortable, and the suspension doesn’t dive under braking.
