If you want to become a bicycle mechanic, you do not need any specific level of formal education, and you do not necessarily need any certifications either, but you will need to develop some mechanical skills and have a passion for bicycles. Many people who consider becoming a bicycle mechanic tend to think this is an easy job, but it requires a significant amount of skills and knowledge regarding bicycles and the current technology associated with bicycles. You may benefit from taking part in a mechanic training course, though you can simply learn on the job by working at a shop under the tutelage of an experienced mechanic.
A high school education will usually improve your chances of getting an opportunity to become a bicycle mechanic. Be flexible with your schedule; you will likely work weekends, especially when you are just starting out, and you may get different shifts week to week. You can start training to become a bicycle mechanic by working on your own bike at home; learn how to do the basics, such as derailleur and brake adjustments, tire and tube installations, and pedal installation and removal. Be honest about your ability level when you approach a shop owner for a job.
Many shops will take on inexperienced employees who will be responsible for customer service and even menial tasks such as cleaning the shop. Whenever possible, shadow a mechanic so you can learn the more difficult tasks such as truing or building wheels; adjusting headset, bottom bracket, and hub bearings; and rebuilding suspension forks. These tasks often take skill and patience, and you may need to practice for several months or even years before you are a master of these techniques.
Alternately, you can attend a bicycle institute that offers an education to prepare you to become a bicycle mechanic. You will learn all the techniques necessary to build and repair bicycles, and you will have credentials that you can show to potential employers, thereby improving your chances of getting hired. Keep in mind, however, that such courses can be expensive, and the pay for a mechanic position will probably not be high. Most mechanics start at minimum wage and work up from there, and in most cases, health and retirement benefits are not available. Paying tuition for such a course, therefore, may not be economically advantageous or feasible for many potential bike mechanics.
