Hey there Margie...

One of the best bits of advice I got on this forum was regarding clip-in pedals (I refuse to call them clipless and am staging my own revolution!)...

But the advice is...

Always unclip yourself on the same side, get in that habit so it becomes locked in your muscle memory, and as you put your foot down, always turn your wheel away from your free foot...

Your bike will always try and lean into the unclipped foot if you turn the wheel away from it, and because it is leaning into you, you will not topple toward the ground on the clipped in side...

Haven't fallen when unclipping myself since! Just brilliant!
