Understanding Pedal Stroke: Smooth vs Choppy

Pedaling technique has gotten complicated with all the biomechanics studies and coaching philosophies flying around. As someone who spent years mashing the pedals with zero awareness of form, I learned everything there is to know about why a smooth pedal stroke matters after a bike fit session changed everything.

Nobody had ever told me I was pedaling wrong. Turns out there’s no “wrong,” but there’s definitely more efficient.

What a Pedal Stroke Actually Is

Probably should have led with this section, honestly. A complete pedal revolution involves multiple phases: the power phase (pushing down), the bottom transition, the recovery phase (pulling through), and the top transition. Most people think of pedaling as pushing down. That’s maybe half of what’s happening.

A smooth pedal stroke maintains tension throughout the circle. A choppy one has dead spots where you’re neither pushing nor pulling – just waiting for the next downstroke.

Why Smoothness Matters

Efficiency. Dead spots in your pedal stroke waste energy. If you’re only producing power on the downstroke, you’re coasting through half the revolution. Your heart rate goes up while your speed stays the same.

Cadence becomes harder to maintain when your stroke is choppy. The bike accelerates and decelerates with each push. Smooth circles keep speed constant, which is mechanically and physiologically more efficient.

Joint stress also increases with stomping versus spinning. Smooth strokes spread load across muscles and reduce peak forces on knees.

The Four Phases

Power phase (12 o’clock to 5 o’clock): This is where most power comes from. Push forward and down, engaging quads and glutes. Most people do this naturally.

Bottom transition (5 o’clock to 7 o’clock): Scrape your foot back like wiping mud off your shoe. This activates hamstrings and maintains momentum through the dead spot.

Recovery phase (7 o’clock to 11 o’clock): Lift your foot rather than just letting gravity pull the other leg. Hip flexors and hamstrings contribute. You’re not pulling up hard – you’re unweighting.

Top transition (11 o’clock to 12 o’clock): Drive your knee forward to set up the next power phase. Smooth riders flow through this; choppy riders pause.

How to Practice

Single-leg drills reveal dead spots instantly. Unclip one foot, pedal with the other. If your stroke is choppy, you’ll feel the bike lurch at the bottom and top of each revolution.

Start with 30-second intervals on each leg. Focus on eliminating the clunk. It feels awkward at first – that awkwardness shows you where your form needs work.

Spin-ups also help. Gradually increase cadence until your stroke breaks down. Note what cadence that happens at. Work on pushing that threshold higher.

Equipment Factors

Clipless pedals help because they allow pulling through the recovery phase. Platform pedals limit you to pushing down. This doesn’t mean you can’t develop smoothness on platforms, but clipless makes it easier.

Bike fit matters enormously. Saddle height, fore-aft position, cleat placement all affect your ability to pedal circles. If something’s off, smoothness becomes impossible regardless of technique.

Crankarm length influences pedaling too. Too long and the top of the stroke feels cramped. Too short and you lose leverage. Most people are fine with stock lengths, but it’s worth considering if you’re having issues.

When Choppy Is Fine

Sprinting. When you need maximum power right now, smooth circles take a backseat to raw force. Sprinters stomp because stomping is fastest for short efforts.

Steep climbing sometimes requires mashing too. When cadence drops below 60 RPM, pulling through becomes less efficient than just pressing harder on the downstroke.

The goal isn’t perfect circles all the time. It’s having smooth technique available when efficiency matters – which is most of your riding.

Progress Markers

That’s what makes developing pedal stroke endearing to us cyclists who’ve worked on it. You’ll know your stroke is improving when single-leg drills feel less awkward, when you can hold higher cadences without bouncing, when you maintain speed with less perceived effort. It’s gradual – don’t expect overnight transformation.

Most recreational cyclists never think about pedaling technique and ride happily for years. But if you want to ride faster or longer with the same energy expenditure, smoothing out your stroke is one of the easiest gains available.
