Explore this buying guide ↗Why consider this model?
- A possible match for a rider who wants supported software to vary resistance automatically while keeping the rear wheel installed, and whose exact tire, axle and frame setup can be checked against Saris's limits.
Tradeoffs to weigh
- Unlike a direct-drive trainer, the M2 presses the rear tire against a roller, so tire choice and roller tension matter. It needs mains power for smart resistance; its 69 dB-at-20-mph and +/-5% figures are manufacturer specifications, not independent promises for a particular room or bike.
