Before 2009, almost all mountain bikes were 26 inch. Until 2009, marmot groundhog bicycle company developed the world's first 27.5-inch/650b vehicle in Washington, USA. Since then, a new wheel diameter revolution has officially arrived in the bicycle industry, and major brands have followed suit to develop this size vehicle. The 27.5-inch / 650B vehicle has gradually become the mainstream product in the bicycle market.
Because each person's body proportion is different, leg length and arm length are different, the simplest and most practical practical measurement method is to wear your shoes, stand on the frame tube, feet and shoulders are the same width, and the crotch should be about 5-6cm away from the frame tube; If the upper tube is close to or close to the crotch, the frame is large. If the upper tube is too far from the crotch, the frame is small. Like off-road riders should choose smaller, crotch and frame tube should be about 6-10 cm distance,. In this way, the handling is good and the safety is high. Because off-road is dangerous, the frame should be smaller. It's easier to ride. It's lighter and cheaper. About 2000 shelves are good.
