Bicycle selection is difficult?
Not at all, just know what to watch. First of all, you should be able to record which bike category meets your needs. Road, mountain, city are the main categories. Also important is the size and geometry of the bicycle. That's why we built this guide by trying to gather basic information divided into categories according to the type of bicycle.
We also on biketoys.gr do not underestimate the aesthetic part. Appearance counts! If someone tells you "but you chose it because it's red?" You jerk your head! The aesthetic piece is almost equally important after resting on a bicycle. That's why we biketoys.gr have chosen a great variety of bikes and we suggest you a complete proposal, a beautiful and quality bike!


Children's bicycles:
Children's bicycles, depending on the diameter of the wheel in inches, can be divided into different sizes. Based on the height and age of the child below we have created a table that will help you to choose the right size.

DIAMETER OF WHEEL HEIGHT AGE
12" 85-100cm 2-4
14" 100-110cm 3-5
16" 110-120cm 5-7
18" 115-125cm 6-8
20" 120-140cm 8-10
24" 135-150cm 9-11+

Mountain Bikes                                                                                  Road bikes

The size of frame (shown in the above picture with blue color) of a bicycle is calculated by measuring the length of the lower tube (seat tube) to the top of the tube (where the seat supports are inserted). It is usually measured in cm for street bikes and inches ('') for mountain bikes. Most manufacturers also give the size of the bicycles in size small, medium, large etc.

Caution! The desired length of the vertical frame is different between mountain bikes and street bikes. As a rule, those bikes that say 'One Size' mean that they do for all riders by adjusting the saddle height. Now for the absolute geometry of bicycle and body you can follow the following tips.

 

City Bikes/Trekking/Fitness:
Choosing the Right Trekking / Travel bike Size: Wheel Size 26 '' & 28 '' This option is a result of the multiplication of our crotch height by 0.66 and so we end up with the theoretical value of the frame size we need in cm. If the theoretical value we have reached coincides with two frames numbers, then we follow the empirical rule, which is characterized by the type of use our bike will have. We choose the smallest size if the use we use is racing and intense. We choose the largest size if the use we make is a leisurely stroll. Alternatively, you can choose the right frame size according to your height using the table below.

HEIGHTS SIZE FRAME TO CM
150-160cm 16" 46cm Lady (cube)
160-170cm 16"-17" 50cm Lady (cube)
163-170cm 17"-18" 46cm
170-178cm 18"-19" 50cm
178-185cm 19"-20"-21" 54cm
185-193cm 21"-22" 56cm

 

 

Full Suspension (front and rear suspension) Mountain Bikes 26''-27.5''29'' inch:
Wheel Size 26''-27.5''-29''. This choice is a result of our crotch height multiplying by 0.225 and so we end up with the theoretical value of the skeleton size we need in inches. 1 inch equals 2.54 cm. If the theoretical value we have reached coincides with two Frames numbers, then we follow the empirical rule, which is characterized by the type of use our bike will have. We choose the smallest size if the use we use is racing and intense. We choose the largest size if the use we make is a leisurely stroll. Alternatively, you can choose the right frame size according to your height using the table below.

HEIGHT SIZE FRAME TO CM
165-170cm 16" 40cm
170-175cm 16"-17" 40-43cm
175-180cm 17"-18" 43-46cm
180-185cm 18"-19" 46-48cm
185-160cm 19"-20"-21" 48-53-51cm
150-160cm 21"-22" 53-56cm

 

Hardtail (Bikes with front suspension) - Mountain Bikes 26''-27.5''29'' inches:
Wheel Size 26''-27.5''-29''. This choice is a result of our crotch height increasing by 0.226 and so we end up with the theoretical value of the frame size we need in inches. 1 inch is equivalent to 2.54 cm. If the theoretical value we have reached coincides with two Frames numbers, then we follow the empirical rule, which is characterized by the type of use our bike will have. We choose the smallest size if the use we use is racing and intense. We choose the largest size if the use we make is a leisurely stroll. Alternatively, you can choose the right frame size according to your height using the table below.

HEIGHT SIZE FRAME TO CM
165-168cm 15" 38cm
160-170cm 16" 41cm
168-177cm 17" 43cm

177-185cm 19" 48cm
183-190cm 21" 53cm

 

Road bikes:
Wheel Size 28''. This choice is a result of the increase of our crotch height by 0.665 and so we end up with the theoretical value of the frame size we need in cm.If the theoretical value we have reached coincides with two Frames numbers, then we follow the empirical rule, which is characterized by the type of use our bike will have. We choose the smallest size if the use we use is racing and intense. We choose the largest size if the use we make is a leisurely stroll.
