Bicycle pedal, quill road type, with toe clip and toe strap (1970s) The quill pedal is a common pedal system on bicycles. It consists of a main axle section that is attached to the bicycle crank arm and contains extensions from the axle to which parallel cage plates are attached at the front and rear of the pedal.

So-called 'clipless' mountain bike pedals use cycling-specific shoes and metal cleats that bolt on underneath (instead of the old plastic cages, or 'toe clips', that wrapped around your feet and from which these pedals derive their name).

Don’t be put off by the idea of being ‘locked on’ to the bike. Clip-less or clip-in pedals are designed by humans for humans. If you are reading this you qualify! Within a few days (or weeks..) the act of clipping in and out will become second nature.

What to look for in platform (flat) pedals. Platform, or flat, pedals differ most by the level of traction provided. Sharper and/or more numerous pins or teeth will give a better grip but they can also be dangerous if you slip.

Lastly, don't be overly tempted by low weight. Mountain bike clipless pedals live a tough life with lots of abuse so function and durability should be your primary concerns. Besides, any lightweight product can feel awfully heavy when you have to carry it home.

There are pro's and cons on both sides of the issue. Clip-in pedals offer a more connected feeling to the bike, the shoes are generally stiffer soled than normal shoes, and this can help with efficiency and comfort on longer rides.

Over the last three or four years I've used my clip-in pedals and cleated shoes less and less. With my mountain bike lying in bits for the fourth year in a row and the recent sale of my road bike I've returned to flat pedals and regular shoes/plimsoles.
