HOW TO FIX A FLAT BIKE TIRE
Sooner or later every cyclist gets a flat. Knowing how to fix a flat tire is a super useful bike repair skill that can save your ride (or save the ride of any stranded cyclist you might come across). It’s relatively easy and doesn’t require many tools.

STEPS TO FIX A FLAT BIKE TIRE
First up: a few simple terms to know for beginners:
* Tire: Outer rubber part of your wheel that touches the ground when you’re riding.
* Inner tube: Fits inside the tire; the source of the flat.
* Rim: Outer edge of the wheel that the spokes attach to.
* Tire bead: The stiff part of the tire that fits inside the rim edge to hold the tire in place.
Alright, now for the good stuff:
PART 1: REMOVE THE WHEEL
1. If you have a V-brake or cantilever brake, disconnect the brake cable from the brake arms.
2. If it’s your back tire, use your gears to shift the chain to the smallest sprocket.
3. Loosen the quick release to free the wheel, or use a crescent wrench if the wheel is attached with nuts. Never used your quick release before? Ask a bike buddy who knows how it works to make sure you take it off – and more importantly, put it back on – properly.
4. Pull the wheel out. If it’s the back wheel, hold the derailleur down as you pull the wheel out.
5. For bikes with disc brakes: once the wheel’s off, make sure you don’t touch the brake levers or you may have trouble getting your wheel back on. If you can’t trust yourself, slip a piece of cardboard between the pads.
PART 2: REMOVE THE INNER TUBE
1. Open the valve and deflate the inner tube all the way. If you have a Presta valve, you’ll need to unscrew the tip of the valve before you press it down with your finger to deflate the tube.
2. Next up: get one side of the tire bead off the rim. Start by pushing the tire all the way around to help loosen it from the rim.
3. If the tire’s tight, tire levers will help. Insert a tire lever between the tire bead and the rim edge (make sure to do this at least 10cm away from the valve area). Use leverage to flip the tire lever over and hook the tire lever onto a spoke to lock it in place.
4. Insert another lever a few centimetres from the first.
5. Push down on one lever, then the other, to free the tire from the rim. Work all the way around the tire until one edge of the tire is off the rim.
6. Reach inside the tire and pull the inner tube out. When you get to the valve, gently pull it through the rim. If there’s a circular nut on the valve, unscrew it to remove the inner tube (put it somewhere safe since you’ll need it later).
