Is My Bike Set Up Correctly? A 7-Point Self-Check
Most riders never find out whether their position is right until something hurts. This is a check you can do at home in fifteen minutes, in order, using nothing but a wall, a mirror or a phone, and it tells you which of your settings is worth changing first.
Check your setup in this order: saddle level first, then saddle height, then knee over pedal, then elbow bend, then how much weight rests on your hands. Each check depends on the ones before it.
Rather than guessing, measure your actual position with your own camera.

Before you start
Do this on a trainer, or with your bike against a wall and someone steadying it. Wear your normal cycling shoes and shorts, because shoe sole thickness changes everything below the saddle.
Work through the checks in this order. Each one depends on the ones before it, so checking reach before saddle height gives you a meaningless answer.
1. Saddle level
Put a straight edge or a spirit level app along the top of the saddle. It should be level, or within one to two degrees of it.
Why first: a nose-down saddle slides you forward and changes every other measurement below. A nose-up saddle presses into soft tissue. Almost every other check is invalid until this one is right.
If it fails: level it before doing anything else, then ride for a week before judging the rest.
2. Saddle height
Pedal backwards slowly with your heel on the pedal. At the bottom of the stroke your leg should be straight, but your hips should stay level, no rocking side to side.
What it means: if you cannot reach with a straight leg, or your hips rock to reach, the saddle is too high. If your heel sits comfortably with a bent knee, it may be too low.
The accurate version: the heel test is a rough guide only. The real measurement is the knee angle at the bottom of the stroke while pedalling normally, around 138 to 145 degrees for endurance road riding, or 140 to 148 in a racing position. That is the number a fitter measures and the one you cannot judge by eye.
3. Knee over pedal
Sit on the bike with the cranks horizontal. Drop a plumb line, a phone charger with a key tied on works, from just below your forward kneecap.
What to look for: the line should fall roughly at or just behind the pedal axle.
If it falls well in front: the saddle is likely too far forward. Well behind: likely too far back. Adjust on the rails, then recheck saddle height, because sliding the saddle back effectively raises it.

Ride, or sit in your normal riding position, hands where you usually hold them.
What to look for: a slight, relaxed bend in the elbows. If your arms are straight and locked, your reach is too long. If your elbows are sharply bent and you feel cramped, it may be too short.
Why it matters: locked arms transmit every bump straight into your shoulders and neck, and they are the single most common cause of upper-body complaints.
5. Where your weight sits
While riding normally on flat ground, briefly lift your hands a few centimetres off the bars.
What to look for: you should be able to do it without lurching forward, and without having to catch yourself. If you fall forward immediately, too much of your weight was resting on your hands, which points at reach, bar height or a nose-down saddle.
Do this somewhere safe and empty, or on a trainer.
6. Back shape
Have someone photograph you from the side while riding, or use a phone on a tripod.
What to look for: a gently curved back, not a sharp bend in the lower back. A sharply rounded lower back means the position is too low or too long for your current flexibility, or that your hamstrings need work before that position becomes available to you.
7. What hurts, and where
Finally, the check that costs nothing: write down where you feel it after a two-hour ride.
- Front of knee → saddle likely too low or too far forward
- Back of knee → saddle likely too high or too far back
- Side of knee → cleats, not saddle
- Hands numb → too much weight forward
- Lower back and neck → bars too low or too far away
- Sit bones and chafing → saddle height, tilt or width
Symptoms point at causes far more reliably than guessing does.
What this check cannot tell you
Two honest limits. First, the eye is bad at angles: you can see that a leg is roughly straight, but not whether the knee is at 138 or 146 degrees, and that difference can decide whether a position feels comfortable or leads to knee pain. Second, static checks miss what happens while you pedal: hip rocking, ankle drop and left-right differences only appear in motion.
That is exactly the gap a video analysis fills. A BikeFit/LAB report measures the angles you cannot judge by eye, knee extension, hip angle, torso lean, elbow angle and saddle fore/aft, from a short video, and returns the adjustments in millimetres with an order to make them in. Use this self-check to find the obvious problems first; measure when you want the numbers.
FAQ
How do I know if my bike is set up correctly?
Work through it in order: saddle level first, then saddle height, then knee over pedal, then elbow bend, then how much weight rests on your hands, then your back shape, and finally where you hurt after a long ride. Each check depends on the ones before it.
How can I tell if my saddle is too high?
Pedal backwards slowly with your heel on the pedal: if you cannot reach the bottom with a straight leg, or your hips rock side to side to reach it, the saddle is too high. Pain behind the knee and chafing on both sides are the other common signs.
Can I do a bike fit myself at home?
You can find the obvious problems yourself with a systematic check, and correcting saddle level, height and fore-aft solves many complaints. What you cannot do by eye is judge joint angles precisely or see what happens while pedalling, which is where a video measurement adds what the eye misses.
