October 29, 2024 - Just prior to Eurobike in early July, Shimano unveiled its EP5 and E5100 drive units targeted to commuters, weekend adventurers, and for families picking up their kids, running errands, etc.

The EP5 boasts a sleek, compact design and a maximum torque of 60Nm for a powerful yet quiet mix of reliable performance including three customizable assist modes: Eco, Trail and Boost.

Along with Auto Shift for both rear derailleur and internal hub gear (IHG) drivetrains, the E-Tube Project Cyclist App allows you to personalize your ride with up to 15 unique assist characters such as Fine Tune mode, Max Torque, and Assist Start in Basic Mode.

With pedal-assist up to 28mph (45kph), this new lightweight EP5 drive unit, Class 3 in the USA, weighs 3kg and balances performance and efficiency.

The new E5100 features up to 50Nm of torque and offers a lightweight and responsive support system at 2.4kg, along with a natural feel and reliable performance for commuting and everyday adventures.

Providing pedal-assist support up to 20mph, you can personalize your ride and customize the level of power with the E-Tube Project Cyclist App. Auto Shift is only available on internal hub gear (IHG) drivetrains.

The range of the EP500 and E5100 e-drive units is based on different battery sizes: 418Wh, 504Wh and 630 Wh. Both systems are compatible with V-brakes, disc brakes, roller brakes and coaster brakes. Shimano’s E-Bike Systems use sensors and drive unit tuning to provide optimal assistance based on real-time riding data
