What is a 7 speed?
Keeping this in consideration, what is a 7 speed automatic?
It means that the transmission in that vehicle has 7 speeds. This helps with fuel economy since many gears give the possibility of keeping the engine at low revs at different speeds. This “crams” more energy into less movement increasing torque and sacrificing top speed since it will accelerate faster.
Beside this, what are 7 speed bikes good for?
A 7-speed bike is a great bike for a person who rides on tricky terrain. It's main purpose is to let the bike adapt to rough conditions and accommodate inclines, bumps and other difficulties. On a 7-speed bike, the lower gears make it easier to pedal and the higher gears allow for better movement going downhill.
7-speed transmissions appeared on extreme high-end supercars, such as the 2005 Bugatti Veyron (semi-automatic manual transmission). In 2012, the Porsche 911 featured a 7-speed manual transmission, becoming the first of its class to support this feature, paving the way for the 2014 Chevrolet Corvette Stingray.
