not have pedals or in which the pedals have been removed from their motorised bicycle. These are better categorised as electric mopeds or electric motorcycles. Legal status (*) Allowed on bike paths when electric systems are turned off (**) E-bikes are illegal in this region (***) Some regions have special regulations, see corresponding entry under Electric bicycle laws. Gallery Popularity E-bike usage worldwide has experienced rapid growth since 1998. China is the world's leading producer of e-bikes. According to the data of the China Bicycle Association, a government-chartered industry group, in 2004 China's manufacturers sold 7.5 million e-bikes nationwide, which was almost twice the year 2003 sales; domestic sales reached 10 million in 2005, and 16 to 18 million in 2006. In 2016, approximately 210 million electric bikes were used daily in China. Most of their manufacturing and distribution plants are based in China. According to trade umbrella body CONEBI, electric bike sales in the EU were over 5 million in 2021, up from 2 million e-bikes in 2016, up from 700,000 in 2010 and 200,000 in 2007. In 2019, the EU implemented a 79.3% protective tariff on imported Chinese e-bikes to protect EU producers. Technical Motors and drivetrains The two most common types of motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. Brushless hub motors are the most common in modern designs. The motor is built into the wheel hub itself, while the stator is fixed solidly to the axle, and the magnets are attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts. Another type of electric assist motor, often referred to as the mid-drive system, is increasing in popularity. With this system, the electric motor is not built into the wheel but is usually mounted near (often under) the bottom bracket shell. In more typical configurations, a cog or wheel on the motor drives a belt or chain that engages with a pulley or sprocket fixed to one of the arms of the bicycle's crankset. Thus, the propulsion is provided
