Like all other Shimano STePS parts, the batteries are compatible with all other motors, shifters and display units so that the overall system can be perfectly tailored to the budget and the intended use. New for 2021 is the 630 Wh internal battery which will join the 504 Wh internal as well as the two existing semi-integrated batteries. All are removable for easy transportation and ‘off the bike’ charging.
