BMX MID BB refers to the Mid bottom bracket part of a BMX Bike. In the construction of a BMX bike, the mid shaft is the key component that connects the pedal crank set to the chain, and is located at the bottom of the frame, responsible for transmitting the force of the rider's pedals to the rear wheel to drive the bike forward. BMX bikes are often used for stunt and competitive riding, so the mid-axle section and the bicycle frame needs to have a high level of durability and strength. the MID BB is designed to provide stable support and smooth rotation for the intense use and frequent stunt performance involved in BMX riding. It uses a finer sealing structure that effectively prevents dirt, moisture and other impurities from entering the inside of the mid shaft to ensure that the mid shaft can work stably during riding, reducing wear and tear and breakdowns. In addition, mid BB is more convenient in terms of maintenance and replacement. It may be designed for easy disassembly and assembly, making it easier for riders to perform routine maintenance and replace parts. The use of a finer sealing structure effectively prevents dirt, moisture and other impurities from entering the interior of the centre shaft, thereby extending its life and reducing the likelihood of failure.
