The Belt Length dropdown will show a 74 Tooth belt with 1. Suitable for servo motor driven robotic arms, they have a robust design with compression springs that engage and capture the brake’s rotor hub immediately stopping arm movement. A smaller driven pulley means a faster turning pulley, thus bringing the blade tip speed of the shorter 42" blade up to the same speed as the larger 48" blade. It would in fact be a perfect electric bike solution if it was possible to pump more power through it reliably. Belts too tight. While there's nothing wrong with the adafruit motor shield for DC motor control, I do prefer an external speed controller, like the L298 Compact Driver from Solarbotics for larger DC gear motors. The world’s most famous riders have taken part in GP events in Brno since 1930, where up until 1982 they would race through the villages and western parts of the city on a road track named after.
