Today, our do-it-yourself knowledge about our bikes and vintage cars is less than it used to be. It is important that we understand the basic technological skills required to maintain them. Whether it is a bicycle, motorcycle or car, regular maintenance is necessary to keep them in good condition, ensure their safety and prolong their life. I am Jochem (26), old-timer fanatic and hobbyist mechanical engineering and I can teach you all the home-garden-and-kitchen knowledge and skills to properly repair or convert your own bicycle. With your bicycle or motor vehicle, we can make a diagnosis together, find the problem and fix it. Whether your unicycle is missing a spoke or whether another engine needs to be fished into your oldtimer; at your home we do it together!
