The Powerfly FS 4 is a full-suspension electric mountain bike that's
eager to hit the trail. It packs in plush suspension to soak up
rough-terrain and a powerful Bosch drive system to boost your capacity
to crush long climbs and mile after mile of singletrack. It's equipped
with Bosch's latest LED remote and Purion display that pair with the
eBike Flow app to give you activity tracking, navigation and Bluetooth
connectivity.
