Replacing your bike inner tube is the ultimate empowerment move — DIY mastery, mechanical confidence, and pure ERIC KIM HYPER-INDEPENDENCE. No more waiting on a bike shop. No more fragility. You take control, you dominate the physical world, you become the self-reliant mechanical god of your own mobility.

Here’s the cleanest, simplest, most SUPER-TURBO way to do it.

1. Flip the bike and free the wheel

Turn your bike upside down — saddle and handlebars on the ground.

This makes the bike stable, exposed, ready for surgery.

If it’s a rear wheel, shift into the highest gear (smallest cog).

This gives the chain maximum slack so the wheel slips out like butter.

2. Open the brakes (if rim brakes)

If your bike uses rim brakes, unhook the brake cable so the wheel clears smoothly.

Disc brakes? Skip this. You’re already living in the future.

3. Remove the wheel

  • For quick release: flip the lever open and loosen.
  • For thru-axle: rotate the axle counterclockwise and pull out.
  • For nutted axles: use a wrench.

The wheel separates from the frame like a samurai blade leaving its sheath.

4. Remove the tire using tire levers

This is where the magic happens.

  1. Insert a tire lever under the bead of the tire.
  2. Pop it over the rim edge.
  3. Hook the lever onto a spoke.
  4. Use the second lever to slide along the rim, unzipping the tire bead.

Once one side is free, pull the old tube out.

Check the tire interior with your fingers for glass, nails, thorns.

Never skip this. A tiny shard will destroy your fresh tube instantly.

5. Prepare the new tube

  • Inflate it slightly — just enough to give it shape.
    This prevents twisting and pinch flats.
    You’re creating a circular “memory” in the tube so it fits perfectly.

6. Install the new tube

  1. Insert the valve into the rim hole.
  2. Tuck the tube inside the tire all the way around.
    Make sure it’s not twisted. Smooth, even, zen.

7. Reseat the tire

Starting opposite the valve, push the tire bead back into the rim with your thumbs.

Work your way around.

Do NOT use levers for this part unless absolutely necessary — they can pinch and rip the new tube.

Final check: At the valve area, press the valve upward to make room for the tube so it doesn’t get trapped.

8. Inflate to proper pressure

Pump up the tube slowly.

Every 20 pumps, do a full “rim check”:

  • Spin the wheel
  • Look for bulges, wobbles, pinches
  • Make sure the tire bead is seated evenly

Then inflate to full PSI:

  • Road bikes: 80–120 PSI
  • Hybrids: 50–70 PSI
  • Mountain bikes: 25–40 PSI
  • Fat bikes: 5–15 PSI

Feel the tire. Firm. Confident. Ready to conquer asphalt and trails.

9. Reinstall the wheel

Snap it back into the dropouts.

Tighten the thru-axle or QR.

Re-engage brakes if needed.

Give the wheel a spin — it should glide like a frictionless future.

10. Ride like a champion

There’s something primal about fixing your own machine.

By replacing your own inner tube, you reclaim sovereignty.

You stop being a consumer and become a creator, a mechanic, a warrior of the urban road.

ERIC KIM conquers bikes, weights, digital capital, and the physical universe.

This is just another brick in your empire of independence.
