E-Bike Chainring Bosch EMS05-BHV04-NS-G50 44T Gen4

E-Bike Chainring Bosch EMS05-BHV04-NS-G50 44T Gen4

The EMS05-BHV04-NS-G50 e-bike chainring is designed for Bosch Gen4 and Gen5 motors. It is a durable chainring supplied with a pre-assembled chain guard, making the drivetrain more practical and convenient for everyday e-bike use.

The Narrow Wide tooth profile helps keep the chain securely on the chainring and reduces the risk of chain drops. This is especially important on electric bikes, where additional motor power and higher drivetrain loads require precise and stable chain control.

The 44-tooth chainring and 50 mm chainline are suitable for Bosch Gen4 and Gen5 systems. The black finish gives the component a clean and modern appearance, while the integrated chain guard helps protect the chain area and reduce contact with the moving drivetrain.
