Di2 E-Bike Components and Accessories
Shimano Di2 is available at different price points for all bike types - this specific page lists all E-Bike or Urban Di2 components.
If you're looking for road / mtb / gravel info, go to the road / gravel / mtb Di2 components page.
Non-series components
All of the Di2 hardware is completely cross-series compatible, meaning that you can mix Ultegra with DURA-ACE and even mtb components if you want to. The hardware below is used on both the Ultegra and DURA-ACE groupsets - and MTB and GRX as well.
