How high is your bicycle seat supposed to be?

I know the frame between the seat and the bars is supposed to touch your groin area when you stand up… but what about the seat? Some people tell me to raise my seat up. You’re supposed to stand at the frame, pedal and jump up to your seat… But there is a lot of traffic… and I read one of the bike laws that said you should be able to stand when your bike is stationary… so? how high guys?

Unfortunately both of those are wrong.

On a road bike, standing over the frame, you should have 1″ of clearance between top tube and crotch. On a mountain-type bike this increases to 3-5″ depending on how the bike is made.

The saddle height should be so that when you are sitting on the saddle with your feet on the pedal, and one of your feet at the bottom of the pedal stroke that your knee should be slightly bent. You should NOT be able to sit on the saddle and touch the ground flatfooted.

The first part of the answer should tell you where you should be standing when you are stationary… to mount the saddle, have the right side (drive side) pedal at the 2:00 position- in front of you- then place your foot on the pedal and push off, hoisting yourself onto the seat. It really takes much more to explain this than to actually do it.

What bicycle tire size is correct?

I have on my bicycle 27 inch wheels with 18 mm rims. The tires i am using now are 28×622 but i want to change them.

Would it be safe to use 23×622 or 25×622 tires ?

I understood from this site http://www.sheldonbrown.com/tire-sizing.html that using tires too narrow could be dangerous. I ride fast and want to go even faster but i want to be safe too.

The best answer is to find the rim manufacturer’s web site, if you can. The technical specs for the rim will tell you the range of tire widths the rim is designed to support.

If you can’t find that information, I’m fairly certain you can go down to a 25 width. You can probably go down to a 23.

Buy good tires with a max tire pressure around 120 psi. If you want to go faster, you need minimum rolling resistance. I’ve had very good luck with Continental tires, but YMMV.
