It's not often when people buy a bike that they pay attention to the size of the frame. But in vain. If the frame is too large for you, then you will ride it without pleasure. You will only get exhausted, or even get hurt.
Instructions
Step 1
All bicycle models have a unique size. Sizes from 16 "to 24" are more common. But there are manufacturers who like to produce frames in half-inch increments (for example, 16, 5). Many people are used to thinking that the distance from the centerline of the carriage to the end of the seat tube is the size of the frame. But in fact, it often turns out that this parameter differs from manufacturers. For example, an 18 "frame from one manufacturer may not be the same as an 18" frame from another manufacturer.
Step 2
When you buy or are about to buy a bike, be sure to measure the distance from the groin area to the upper tube. Let it be no less than 8-10cm. To do this, this is done so that in case of a sharp brake and a simultaneous jump from the bike, you do not get hurt. If you are not going to recklessly, but will drive calmly, you can ignore this recommendation. But still, it is not recommended for anyone to purchase a bicycle with a designated distance of less than 5 cm.
Step 3
On the model you like, pay attention to the fit. Landing should be as comfortable as possible. You don't want to get tired and drive at low speed forever, do you? And this will be the main disadvantage of an incorrectly selected landing.
Step 4
Examine the saddle carefully. Adjust it immediately in height so that your leg, when driving, bringing the pedal to the lowest position, is fully extended. If it does not straighten, then you need to purchase a larger saddle.
Step 5
Be sure to make sure you can reach the steering wheel calmly and effortlessly while driving. Don't want to lean back a little more or bend even more forward. Otherwise, back pain may then begin due to an unhealthy position.
Step 6
Let's say you want to order a bike online. There is no need to rush. It is better to first go to a regular store, find there the model you like. Follow all the recommendations above. Ride this bike and only then order. Otherwise, it may turn out that the purchased model does not suit you and instead of pleasure you will have to experience resentment and discomfort.
