On our market there are now a lot of imported bikes with a large (over a dozen) number of speeds. But fascinating these machines are, perhaps, only youths. Experts understand that to take full speed full still impossible: difficult even to choose the correct gear and often switch them on the go is not only tiring but also unsafe. Because switching is required usually in difficult driving conditions or cornering, when the hands should firmly hold the steering wheel, and one of them is necessary to manipulate the lever. As you know, the cars are only 4 — 5 speeds, and the drivers prefer to upgrade to automation.MULTI-SPEED FLOATMATH
