Choose this one if

  • You want Concept2’s monitor and data but rowing aggravates a back or shoulder issue
  • You do interval work where a flywheel that spins down fast matters more than road feel
  • You already have a RowErg and want a second modality with numbers on the same scale

The detail

The BikeErg is the same idea as the RowErg applied to a bike: air resistance, a PM5 monitor, and output measured in watts rather than in a proprietary resistance level. If you already know what a hard 500-metre effort feels like on a rower, the bike speaks the same language.

The flywheel is light and spins down quickly compared to a spin bike’s heavy weighted wheel. That’s a deliberate choice and it’s the whole argument for the machine: when you stop pedalling, resistance stops, which makes it excellent for short hard intervals and poor at simulating the momentum of riding outdoors. If you’re training for road or gravel, this is the wrong tool — buy a smart trainer and use your own bike.

Adjustment range covers saddle height, fore/aft position and handlebar height, which is enough to fit most people but short of a proper bike fit. The saddle is a standard rail mount, so replacing it with something you can actually sit on for an hour is easy and, for most people, necessary.

Same practical virtues as the rower: no subscription, no account, D-cell batteries, and a company that still sells parts for machines from the 1990s. Same drawback too — air resistance is loud.
