How to pump up Schrader valve bike?
- I have a Schrader valve bike with deflated wheels. When I try to pump it up. I take off the protective cap, then there is a valve secured down by a nut (there is another nut securing it to the actual wheel) I then put the pump onto the bit of valve poking up and lock it in. I can then pump it completely with about 5 pushes of the pump.

Do I need a special pump for a Schrader valve?
Schrader valves are most commonly found on bikes with wide rims and are the same style you’ll find on most automobiles. They use an internal spring to allow inflation while keeping the valve closed. You can inflate this style easily with any regular air pump.
What is a Schrader valve on a bike?
The Schrader valve (also called American valve) is a type of pneumatic tire valve used on virtually every motor vehicle in the world today. The Schrader valve consists of a valve stem into which a valve core is threaded. The valve core is a poppet valve assisted by a spring.

What is the difference between Presta and Schrader valves?
Schrader valves are wider and typically shorter than Presta valves. They are the valve type that you see on car tires, so they are more universal than Presta. Schrader valves consist of a threaded outer wall (to accept a cap) whose bottom half is wrapped in rubber and a spring-loaded check valve in the center.
Can I put a Presta valve in a Schrader rim?
A Presta tube can be used with a Schrader rim but only with a special adaptor known as Schrader – Presta grommet which fills the space around the new Presta valve and secures it. Without a grommet, the tube may puncture near the valve stem from excessive movement or from pressing against the edges of the entry point.
Which is better Presta or Schrader valve?
Presta valves are easier to pump than Schrader, because they have no valve spring to overcome. In narrow rims, clincher tires also leave insufficient space between tire beads for larger Schrader valves. In contrast Schrader valves are more robust, universally used, and have an easily removable core.
How do you pump up a bike tire without a pump?
Manually Inflating a Tire Begin by blowing a small amount of air into the tire. You’ll want to use your tongue to put pressure on the valve to keep it open. After you’ve inflated the tire a little, stop and check to see if the tire is properly positioned on the rim.
