Knee pain while cycling is a common problem – whether you regularly ride a road bike, tackle mountain bike trails, or commute leisurely on an e-bike. Knee pain limits performance, can lead to injuries in the long run, and simply takes the fun out of cycling. Cycling is actually good for the knees , so what should you pay attention to?

The good news: Many knee problems can be avoided or significantly reduced if you know the causes and adjust your bicycle optimally to your own body.
The knees are subjected to considerable stress during cycling – with every pedal stroke, forces act on the joints, tendons, and muscles. If the position on the bike is incorrect or the strain is too high, the knee will react with pain.
Incorrect saddle height
Saddle too low: The knee remains bent at a sharp angle, which can overload the tendons and cause pain at the front of the knee.
Saddle too high: The leg has to overextend with every pedal stroke, the hamstring muscles are overloaded, and the knee can be overloaded.
Optimization: A rough rule of thumb: With the saddle height correctly adjusted, the leg should be slightly bent at the bottom dead center, about 25–35°.
Saddle position (front/rear)
If the saddle is too far forward, the knee is pulled forward when pedaling, which increases the pressure on the kneecap.
If placed too far back, the knee can be bent too much and cause pain on the inside.
Tip: The saddle position should be chosen so that when pedaling, the kneecap is approximately vertically above the pedal axle .
Pedal and cleat position
With clipless pedals, an incorrect cleat position can lead to unnatural knee movements.
Even normal pedals can put pressure on the joint if the foot is positioned incorrectly.
Tip: Adjust pedals and cleats correctly and, if necessary, choose shoes with suitable stiffness.
Overload or training errors
A sudden increase in training intensity or volume can overtax the knees.
Common causes include insufficient warm-up, excessive hill training, or excessively high cadence .
Tip: Gradually increase training volume, incorporate short warm-up phases , and slowly get the knee used to new stresses.
Physical weaknesses or muscular imbalances
Weak thigh muscles, shortened calves or hip muscles can put a lot of strain on the knee.
A muscular imbalance can create incorrect loads that manifest as pain.
Solution: Incorporate targeted strength and stretching exercises.
If the knee is already hurting, some measures can help in the short term:
Take breaks: Reduce the strain and give your knee a rest.
Cold or heat applications: cold for acute pain, heat for tense muscles.
Stretching exercises: Regularly stretch your quadriceps, hamstrings, and calves.
Muscle strengthening: Light strength exercises for the thighs, buttocks and torso help to stabilize the knee.
Checking shoes and pedals: Check the correct shoe size, stiffness, and pedal position.
Many knee problems can be permanently prevented through a professional bike fitting . A bike fitting takes the following into account:
Height, leg length, mobility
Seat height, saddle position, handlebar height
Pedal position and shoe/cleat adjustment
These adjustments distribute the load evenly across the knee , relieving stress on tendons and joints, and increasing pedaling efficiency. The result: less pain, greater comfort, and improved performance.

Regularly check the saddle height and position – small adjustments can have a big impact.
Warm-up before longer tours – 5–10 minutes of light pedaling is often enough.
Strength training can be added – the thighs, buttocks, torso and calves stabilize the knee.
Gradual increase in training intensity – avoid overload.
Listen to your body's signals – react early, before mild pain becomes chronic problems.
Knee pain while cycling isn't inevitable. It's usually caused by incorrect bike setup or overuse . With targeted prevention, quick fixes, and a professional bike fitting, you can effectively prevent pain. This way, cycling remains pain-free, efficient, and above all, enjoyable .
Eine GPS Uhr ist längst nicht mehr nur ein Gadget für Läufer. Auch beim Radfahren – egal ob Rennrad, E-Bike oder Mountainbike – kann sie ein extrem praktischer Begleiter sein. Doch welche Funktionen sind für Fahrradfahrer wirklich relevant? Und wann lohnt sich eine GPS Uhr zusätzlich zu einem GPS-Tracker fürs Fahrrad?
For many road cyclists, longer rides are the epitome of freedom: rolling for hours, enjoying the scenery, clearing their heads – and pushing their endurance to a new level. At the same time, long rides place special demands on the body, equipment, nutrition, and mental strength .
Many people still believe that long, moderate workouts are the key to good health. However, a new large-scale study shows that short, intense bursts of activity are significantly more effective than previously thought —especially when it comes to cardiovascular health, metabolism, and longevity. What does this mean specifically for cyclists, e-bike commuters, or ambitious amateur athletes? This article explores precisely that question.
