The plush suspension set-up soaks up rough terrain and the powerful Bosch electric drive system boosts your capacity to crush long and punchy climbs and mile after mile of singletrack. The new LED remote and Intuvia 100 display pair with the eBike Flow app to give you activity tracking, navigation and Bluetooth connectivity.
