Common Cycling Issue, Discomfort

This Q&A offers general guidance for self-assessment only. It is not a substitute for a professional Bike Fitting. Cycling pain is complex and requires dynamic analysis of your unique anatomy to resolve the root cause.

The saddle height is crucial and can be roughly checked using the heel-to-pedal method.

1. Stand beside your bike and adjust the saddle height to approximately your hip bone level.
2. Sit on the bike and place your heel on the pedal when it is at the bottom dead center (6 o'clock).
3. If your leg is fully straight, the saddle height is a good starting point (approximately 70% correct).
4. If your knee is still bent, raise the saddle.
5. If your heel loses contact with the pedal or your hip rocks, the saddle is too high, lower down the saddle.
6. Use your forefoot to pedal.

This method provides a safe position to prevent basic knee pressure. However, achieving optimal power transfer and efficiency requires dynamic measurement of knee extension angle (usually 135-145 degrees) under load, which can be precisely set using our 3D Motion Capture System.

Neck pain is often complex and rarely caused by one factor.

• Overly Aggressive Setup - Saddle to handlebar drop is too large
• Beginners' posterior neck muscles are unconditioned for the sustained static position.
• Riding in the same posture for too long.
• Helmet is too heavy
• The upper frame of the glasses obstructs the view, requiring excessive tilting of the head.

Lower back pain is typically a failure of the core to stabilize the spine, amplified by the bike setup:

• Incorrect Saddle Angle
• Reach is too long (Aggressive): Forcing the rider into a stretched, unsupported, and often rounded-back posture,
• Reach is too short: Forcing round back.
• Overly Aggressive Drop: Large saddle-to-handlebar drop.
• Riding intensity is too high
• Gear ratio is too heavy

Hip pain often stems from restricted range of motion or improper muscle firing:

• Crank Arms is too long
• Saddle height is too low
• Saddle position is too far backward
• Shoe cleat position is too far forward
• Relying too much on the hip flexors (too pulling up on the pedals)
• Riding intensity is too high
• Gear ratio is too heavy

Pain or numbness here is a direct result of excessive pressure on the soft tissue, usually due to the contact point:

• Rider's weight is too heavy
• Incorrect Saddle Shape/Hardness
• Saddle position is too far backward
• "Casual" Riding Style: Failing to effectively transfer weight to the pedals, leaving too much load on the saddle.
