The bike is still attractive as it does not require long and costly maintenance, is light and handy. The human-powered bicycle is a nature and environment friendly vehicle in addition to motorized transportation vehicles. In this study, in general a bicycle frame design suitable for daily and mountain roads, ergonomically designed according to human body size was designed and the stresses and elongations that occur in the analysis programs were examined.

INTRODUCTION With the development of technology, human beings, who can easily cover long distances, have not been able to give up bicycles, although they are advancing in the field of transportation every day. The bike is still attractive as it does not require long and costly maintenance, is light and handy. The human-powered bicycle is a nature and environment friendly vehicle in addition to motorized transportation vehicles [1]. The origin of the bicycle dates back to 200 years ago. In 1817, German Baron Karl von Drais invented the two- wheeled vehicle that was the prototype of the modern bicycle [1]. Drais used the vehicle to be able to move faster. The rider was advancing by pushing his foot off the ground in the pre-pedal period [1]. Patented by Von Drais on June 26, 1819, the vehicle became popular in many countries such as Austria, the United Kingdom, Italy, and the United States. Drezin was developed over time and evolved into a bicycle [1]. Pierre and Ernest Michaux designed the first pedal bike. Two French father and son named Pierre and Ernest Michaux put pedals on the front wheel hub of the vehicle built by Drais. So the real bike was invented [1]. After that, the curiosity for cycling started to spread much faster all over Europe. Father-son started mass production by establishing the "Michaux Company" [1]. Today, highly developed bicycles are used in many areas such as mountain bikes, racing bikes, model kids bikes, city and road bikes, fitness bikes, electric bicycles, service bikes [1, 5, 6]. II. MATERIALS AND METHOD In this study firstly, it was determined the size and weight of the bike user. An individual of 180 cm and 80 kg is approximately 60 cm in arm length and 80 cm in inside leg length. Lifting the handlebar and pedal distances of the bicycle by using these measurements. Bicycle squad selection has a major impact on cycling comfort. When one of the simplest methods that helps us choose the minimum of the frame is from the seat, the frame deems it appropriate to have a distance of 10 cm between the upper tube and the crotch. But in a more professional sense, all the angles of the cycling frame were important for sportive riding [2]. The dimensions in the Table 1 may vary according to bicycle types and brands [2]. Calculations and measurements are approximate
