E-Motion Rollers are the most advanced rollers available, and are as close to the road as you can get indoors! We pack a ton of innovation, reliability and craftmanship into each one.

Rollers are available in 3 different option packages: MANUAL, SMART and ULTIMATE FLEX
*MANUAL features 4 hand selected resistance settings. Select the resistance level before getting on the bike.
*SMART features our SmartPower adaptive resistance control.
*ULTIMATE FLEX is the Smart package with the addition of the FFS (Floating Fork Stand) which allows you to quickly switch from a roller to a rocking “Flex trainer” to get the most out of your Zwift sessions. It’s like two machines in one!

SmartPower RESISTANCE - ANT+ FEC and BLUETOOTH. Compatible with apps such as Zwift, TrainerRoad,, etc.
SmartPower resistance control is available as a factory installed option with new rollers.

*Max slope 10%. Max power 800 watts @ 28mph

*Includes ios or Android app for stand-alone operation. Makes setup easy and updates firmware automatically.
* Connects to your power meter for enhanced accuracy and self calibration
* 3 ride modes: RESISTANCE, ERG AND SIM. Indicator lights give status at a glance
* Factory installed means no assembly required...ready to ride straight out of the box

A note about ERG: This mode automatically adjusts resistance to hold a wattage target. It is sensitive to speed, so large changes in cadence or gear selection during the ride can disrupt the power response. For best results, do not change gears or cadence during the ride.

SmartPower is compatible with ANT+ power meters and FEC apps. Also compatible with Bluetooth FTMS for smart trainers.
