help StagesBike SB20 FAQ
How much does the StagesBike SB20 weigh, and is it easy to move between rooms?
The StagesBike SB20 weighs approximately 55 kg (121 lbs), which is comparable to other premium smart bikes like the Wattbike Atom. It includes transport wheels on the front stabilizer for repositioning, but moving it requires significant effort and ideally two people.
What power meter technology does the StagesBike SB20 use for measuring watts?
The SB20 uses Stages Cycling's proprietary dual-sided crank-based power meters, providing independent left and right power measurement with a claimed accuracy of plus or minus 2%. This is the same sensor technology Stages uses in its outdoor crank-based power meters for road and gravel cycling.
Is the StagesBike SB20 compatible with Zwift and TrainerRoad?
Yes, the SB20 connects via Bluetooth and ANT+ FE-C to Zwift, TrainerRoad, Rouvy, FulGaz, and other major indoor training platforms. It supports ERG mode and automatic gradient changes controlled by these apps during virtual rides and structured workouts.
How does the StagesBike SB20 compare to the Wahoo KICKR BIKE?
Both are premium smart bikes with built-in power meters and gradient simulation, but the SB20 uses dual-sided crank-based power meters while the KICKR BIKE uses an internally measured system. The KICKR BIKE also offers simulated virtual shifting and gearing customization, while the SB20 uses a traditional gear setup with physical shifting.
