These are easy to fold to either side, making them ideal for folding bikes or bikes with pedals that are too wide for the bike rack. The boron steel axle, combined with the one-piece PA (highly wear-resistant plastic) pedal body, makes the pedal very powerful. For optimal pedaling comfort, the pedal features a patented PA bearing (ZU bearing). The pedals also have a non-slip surface with studs for maximum grip and reflectors for high visibility. The pedal can be installed with an Allen key. On a hanging card.
