Shimano launches e-Cargo EP8 and E6100 drive units
Shimano has announced the launch of two new models of e-Cargo drive units, further strengthening its position in the e-bike market. The EP8 and E6100 cargo-specific drive units come with built-in features designed to power heavy loads.
Both models will now be available in specific cargo variants called DU-EP800-CRG and DU-E6100-CRG, and are compatible with Shimano gear systems, such as Nexus internal hub gears or derailleur / cassettes. In addition, the models can be supplemented with Shimano brake systems, approved for cargo bikes.
While the drive units are Shimano’s regular DU-EP800 and DU-E6100 models, inside the unit several differences can be found. Shimano engineers studied the handling characteristics of E-Cargo bikes and created new specific firmware settings optimized to propel heavy loads (up to 250 kg).
DU-EP800-CRG and DU-E6100-CRG models come with Eco, Normal (or Trail) and High (or Boost) modes. Both cargo drive units achieve maximum output torque at much lower pedaling torque inputs. The difference between the two units is that the EP8 drive unit performs better with a powerful but quieter motor, while the E6100 version offers more gradual acceleration with lower output torque.
The more advanced DU-EP800-CRG model comes with many of the same functions and features as Shimano’s EP8 mountain bike drive unit. It is a light and compact model with a design that fits perfectly into bicycle frames. It is a light and quiet model when coasting or pedaling, even under load. It also provides a smooth pedaling action even without assistance. The model also features cooling fins on the outer shell that allow heat dissipation and optimized internal gear mechanisms also help reduce heat.
The DU-EP800-CRG has a maximum output torque of 85Nm, which is achievable in Boost and Trail modes, and also has a battery-saving Eco mode and smart walk assist mode. integrated. The DU-E6100-CRG is slightly larger than the EP800-CRG version but also offers smooth pedaling under load or without battery assistance, walk assistance, start mode and fully automatic gear shifting. However, the maximum output assistance provides 60Nm.
Both drive units are compatible with Shimano 630Wh, 514Wh or 408Wh batteries, or they can be combined with third party batteries from Shimano partners such as Trend Power or Darfon. A full list of compatibility options is available at Shimano website. The two new models will be available in summer 2021.
