What are the differences between bicycles? What are the major features that one should know about? Well, there's quite a few features about the bicycles. First of all, we have to find out what type of work you're going to do with the bicycle and the type of

00:00:24.489 - 00:00:38.150

terrain that you're going to be working in. So that we would have the three speed for a fairly flat area, the five speed and the 10 speed for your hilly and greater hilly area. Since you live in San Francisco, you probably would be interested more in

00:00:38.159 - 00:00:53.639

the 10 speeds since greater versatility, Jack, I noticed that there are three different kinds of handle bars. Now, how do you distinguish among those? Which do you use? Well, you have your touring bars which are your upright bars which causes you to sit more on your

00:00:53.650 - 00:01:09.089

saddle and less leaning on the saddle, which is a type of writing that you do if you don't write a great deal, a leisurely kind of leisurely kind of writing and then you have the other extreme, you have the sport bars which causes you to lean

00:01:09.099 - 00:01:24.680

forward and you have a three point stance so that you're leaning on your seat, leaning on your handlebars and literally standing or running on your pedals. And then in between that, you have a combination bar, the one that we call the all rounder bar, which gives

00:01:24.690 - 00:01:41.449

you the benefit of standing on the pedals and giving your three point stance without the drop bar effect of it. So that's, that's sort of a compromise, right? It's a compromise bar. It gives you more of a flexible thing. If you're not a serious rider, you

00:01:41.459 - 00:01:54.889

can still do a lot of serious work without having this serious type of equipment. Hi, Jack, we've decided that I live in San Francisco. So I need a 10 speed bike and one with an all around in between combination handle by here. What do I do

00:01:54.900 - 00:02:08.440

next in picking a bicycle? Next thing we try it for science to see how you're going to fit this particular bicycle? Ok. How do we decide that sit on the seat, your feet would be touching the ground, your toes, touching the ground with four inches of

00:02:08.449 - 00:02:24.800

lift behind your heels or three inches? In case of a lady, this gives you sufficient bend at the bottom of your stroke here, so that it allows you to have a physical advantage in where you're pushing or kicking your pedals through on the down stroke, on

00:02:24.809 - 00:02:39.089

the front of half of each one of your strokes you're pushing down on your pedals. What am I going to be able to do with all these 10 speeds. Well, unlike an automobile, the speeds on a bicycle are not progressive. You don't have to go through

00:02:39.100 - 00:02:56.210

gears, use your gears when the terrain changes or when you fatigue or get tired. In the case of a 10 speed, you have twice as many different arrangements that you can call upon and the different terrains that you are on or the different conditions that you're

00:02:56.220 - 00:03:10.960

in the night after a bad night, you might need lower gears than you would if you were feeling fresh and you were riding on the flat jack. Tell me about the difference between a boy's bike and a girl's bike and how they're being used today. The

00:03:10.970 - 00:03:26.660

girls, the young girls are riding the boys bicycles more for prestige than anything else because these are the things that were available. But uh they're young and agile and still green, they can throw their leg over like the boys do like they were mounting a horse.

00:03:26.669 - 00:03:43.880

Whereas mounting a girl's bicycle, a lady's bicycle because of the nature of the lady's build, it's easier for them to step over the center of the bicycle and then sit up onto the seat and uh the older you become, the more this is necessary.
