Sun Huangmin and his team members are a group of young people with a passion in Nanchang city, Jiangxi province. Now, their dream will come true after two years of unremitting efforts.

They have created a smart wheel hub, which can be installed in almost all bicycles to provide power. The wheel hub can drive bicycles to run up to about 30-100 km on a single charge based on speed. Because the wheel hub can be connected with a smartphone, riders can adjust the riding speed via its app.
