Brazilian made Motorella motorized bicycle, (bike with motor). These are very common in South America and are made by a company called Micro Machine. Variations of this bike are used by the Brazilian post office for mail delivery. This bike hasn't seen much use and motor runs well. The 2 stroke engine is quite powerful and is started by recoil starter. It uses 50:1 premix in a rear carrier mounted fuel tank that lasts for ages. It has a centrifugal clutch and only one speed. It has a set of bicycle pedals and can be ridden as a pedal bike. No lights and the brakes are bicycle type and quite adequate. I doubt if I have ridden it a total of 50 miles since new. No registration is required to the best of my knowledge. Great bike for hacking around the neighborhood or the back forty! Bike is in Houston, Texas and is pick-up or delivery only in Houston.
