What happens in your brain when you ride a bike?

Updated

Visual cortex processes the scene, premotor cortex plans movement, motor cortex executes commands, cerebellum coordinates balance, and somatosensory cortex provides feedback—together enabling smooth cycling.

Visual Cortex, Premotor Cortex, Motor Cortex, Cerebellum, Somatosensory Cortex lit up on the Brain Atlas 3D brain: what happens in your brain when you ride a bike
Figure. The brain regions that light up when you ride a bike, in order: Visual Cortex (seeing the road), then Premotor Cortex (planning the moves), then Motor Cortex (commanding muscles), then Cerebellum (balancing and smoothing), then Somatosensory Cortex (feeling the bike).

Brain regions that light up

OrderRegionWhat it does here
1Visual CortexThe visual cortex processes the road, obstacles, and motion.
2Premotor CortexThe premotor cortex plans the sequence of muscle activations.
3Motor CortexThe motor cortex sends signals to leg and arm muscles.
4CerebellumThe cerebellum fine-tunes movement using feedback.
5Somatosensory CortexThe somatosensory cortex integrates touch and body position.

1. Visual Cortex: seeing the road

Step 1 of what happens in your brain when you ride a bike: Visual Cortex lit on the Brain Atlas 3D brain
Figure 1. Visual Cortex, seeing the road: The visual cortex processes the road, obstacles, and motion.

The visual cortex processes the visual scene, identifying the road, obstacles, and motion. It sends this information to other brain areas for planning. Without this processing, you could not navigate the bike safely.

2. Premotor Cortex: planning the moves

Step 2 of what happens in your brain when you ride a bike: Visual Cortex, Premotor Cortex lit on the Brain Atlas 3D brain
Figure 2. Premotor Cortex, planning the moves: The premotor cortex plans the sequence of muscle activations.

The premotor cortex uses visual information to plan the sequence of muscle activations required for pedaling and steering. It prepares the motor commands before they are sent to the primary motor cortex. This planning occurs just before movement begins.

3. Motor Cortex: commanding muscles

Step 3 of what happens in your brain when you ride a bike: Visual Cortex, Premotor Cortex, Motor Cortex lit on the Brain Atlas 3D brain
Figure 3. Motor Cortex, commanding muscles: The motor cortex sends signals to leg and arm muscles.

The primary motor cortex sends neural signals down the corticospinal tract to activate leg and arm muscles. It has a somatotopic organization, with specific areas for different body parts. These signals produce the voluntary movements of cycling.

4. Cerebellum: balancing and smoothing

Step 4 of what happens in your brain when you ride a bike: Visual Cortex, Premotor Cortex, Motor Cortex, Cerebellum lit on the Brain Atlas 3D brain
Figure 4. Cerebellum, balancing and smoothing: The cerebellum fine-tunes movement using feedback.

The cerebellum receives a copy of the motor command and sensory feedback from the moving limbs. It compares intended and actual movement, then sends corrective signals to fine-tune ongoing motion. This ensures balance, smooth pedaling, and coordination.

5. Somatosensory Cortex: feeling the bike

Step 5 of what happens in your brain when you ride a bike: Visual Cortex, Premotor Cortex, Motor Cortex, Cerebellum, Somatosensory Cortex lit on the Brain Atlas 3D brain
Figure 5. Somatosensory Cortex, feeling the bike: The somatosensory cortex integrates touch and body position.

The somatosensory cortex processes touch, pressure, and proprioceptive signals from the body, including the hands on the handlebars and feet on pedals. It informs the brain about limb position and contact with the bike, allowing real-time adjustments to maintain stability and control.

Good to know

  • The cerebellum contains more neurons than the rest of the brain combined, reflecting its critical role in motor coordination.
  • Proprioceptive feedback from muscle spindles and joint receptors is essential for maintaining balance while cycling.
  • Basal ganglia help automate well-learned movements, making cycling effortless with practice.

Learning to ride vs expert riding

When learning, the prefrontal cortex is highly active as you consciously monitor balance and pedal timing. Once mastered, activity shifts to the cerebellum and basal ganglia, allowing automatic, effortless cycling. This shift reflects the transition from controlled to automatic processing.

Test yourself

  1. Which brain region is primarily responsible for planning the sequence of movements before you start pedaling?

  2. What role does the cerebellum play during cycling?

  3. Damage to which brain region would most likely impair your ability to maintain balance while riding a bike?

Simplified: many regions work together at once, and this shows the main players in the order they act.
