You’ve been doing it since you were six. Or maybe you just started. Either way, riding a bike feels like second nature until your lower back starts screaming or your toes go numb ten miles into a Saturday cruise. It’s funny because we treat cycling like this "set it and forget it" skill. You hop on, you pedal, you move. But there is a massive gap between just moving and actually riding with efficiency that doesn't wreck your joints over time.
Most people think the seat is just for sitting. It’s not. It’s a pivot point. If your saddle height is off by even a few millimeters, you’re looking at a 10% to 15% drop in power output and a fast track to chronic knee inflammation. I've seen it a thousand times. A rider pulls up to a stoplight, struggling to touch the ground with their tippy-toes while staying on the seat, which is actually a sign their seat might be too low, not too high. If you can sit on your saddle and put both feet flat on the ground, your knees are going to pay for it later.
The Biomechanics of the Perfect Pedal Stroke
Let's talk about the "dead spot."
When you’re riding a bike, most of the work happens between the 1 o'clock and 5 o'clock positions of your pedal rotation. This is the power phase. However, a lot of casual riders treat their pedals like buttons—they just mash down. This "mashing" creates a jerky, inefficient movement that wastes energy and puts immense pressure on the patella. Instead, think about scraping mud off the bottom of your shoe at the bottom of the stroke.
Phil Burt, a world-renowned cycling physiotherapist who worked with British Cycling and Team Sky, often emphasizes that the foot should remain relatively level. If you point your toes down too much, you’re over-utilizing your calves and missing out on the massive power generated by your glutes and hamstrings. It’s basically like trying to run a marathon on your tiptoes. You’ll burn out in minutes.
Why Your Core is Actually Your Engine
People assume cycling is all about legs. It isn't.
If your core is weak, your hips will rock side to side on the saddle. This rocking motion is the primary cause of saddle sores and lower back pain. When your pelvis is unstable, your legs have to work harder to compensate for the lack of a solid platform. Think of your torso as the anchor. If the anchor is moving, the chain can't pull effectively. You want a "quiet" upper body. Watch a pro like Marianne Vos or Remco Evenepoel; their upper bodies are nearly motionless while their legs are churning at 90 RPM.
Common Mistakes That Kill Your Ride
I honestly see this one every single day: the "death grip" on the handlebars.
You’re stressed, you’re climbing a hill, or maybe you’re just nervous about traffic, so you squeeze the bars like you’re trying to choke them. This tension travels straight up your arms, into your shoulders, and settles right in your neck. It’s a recipe for a tension headache. You should be able to play the piano on your handlebars. Your elbows should have a slight bend to act as natural shock absorbers. If your arms are locked straight, every bump in the road sends a jarring vibration directly into your spine.
Then there’s the gear issue.
Cross-chaining is a silent killer of bike drivetrains. This happens when you’re in the big ring in the front and the biggest gear in the back (or vice versa). It stretches the chain at an extreme angle. Not only does it make an annoying grinding sound, but it also increases friction, meaning you’re working harder to go slower. Stay in the middle of the cassette whenever possible. It's just basic physics.
The Science of Cadence
What’s the magic number?

For years, the "Lance Armstrong effect" had everyone trying to pedal at 100+ revolutions per minute (RPM). While high cadence shifts the load from your muscles to your cardiovascular system, it’s not for everyone. A study published in the International Journal of Sports Medicine suggests that for most amateur riders, a cadence between 80 and 90 RPM is the sweet spot for efficiency.
If you go too slow (grinding), you’ll fatigue your muscles and risk ligament tears. If you go too fast without the cardiovascular base, you’ll just bounce on the saddle and get out of breath. It’s a balance. Listen to your heart rate. If it’s spiking but your legs feel fine, shift to a harder gear. If your legs are burning but you’re breathing easy, shift to an easier gear and spin a bit faster.
Real Talk About Saddle Pain
Let's be real: bike seats are uncomfortable at first.
But there is a difference between "I haven't ridden in months" soreness and "Something is wrong" pain. If you feel numbness, stop immediately. Numbness is caused by compressed nerves and restricted blood flow in the perineum. This isn't something to "tough out."
Often, the solution isn't a wider, squishier seat. In fact, huge gel seats are usually worse because the extra padding migrates into the areas where you don't want pressure. You want a saddle that supports your siter bones (ischial tuberosities). Most local bike shops have a tool—basically a piece of memory foam—that you sit on to measure the width of these bones. Get the right size. It changes everything.
Safety and the "Predictability" Rule
Riding a bike in traffic is a game of psychology.
The biggest mistake riders make is being too timid. If you hug the curb too closely, you’re inviting cars to squeeze past you in the same lane. This is called "the door zone," and it's where a lot of accidents happen. Sometimes, the safest thing to do is to "take the lane." By riding in the middle of the lane, you force drivers to make a deliberate, safe pass when the other lane is clear.
Be predictable. No sudden swerves. No sidewalk-to-road hopping. Signal your turns with your arms. It sounds dorky, but communication reduces the "friction" between cyclists and motorists. Research from the Insurance Institute for Highway Safety (IIHS) consistently shows that visibility and predictable behavior are the top factors in preventing urban cycling collisions.
Actionable Steps for Your Next Ride
Stop guessing.
If you’re serious about riding a bike without hurting yourself, start with a basic self-assessment.
- Check your saddle height: Stand next to your bike. The seat should be roughly level with your hip bone. When you’re on the bike with your pedal at the 6 o'clock position, your knee should have a 25 to 35-degree bend.
- Audit your gear: Are you cross-chaining? Look down. If the chain is at a diagonal angle, shift.
- Loosen the grip: Every 10 minutes, consciously wiggle your fingers and drop your shoulders.
- Hydrate before you’re thirsty: By the time you feel thirsty, you’re already 2% dehydrated, which can lead to a 10% drop in physical performance.
Invest in a pair of padded cycling shorts (bib shorts are even better). Wear them without underwear—yes, really—to prevent chafing. If you're still experiencing localized pain, look into "chamois cream." It’s a literal lifesaver for long-distance rides.
Riding a bike is one of the few ways to stay fit that is low-impact and actually fun, but only if you respect the mechanics of the machine and your own body. Correcting your form today prevents the chronic issues that keep people off their bikes five years down the road.
