Sunny Health SF-B1002

Averaged from + undefined
The verdict

The SF-B1002 is the heavy-flywheel pick. Its 49 lb chrome flywheel is the heaviest in this lineup by a wide margin — the pedaling feel approaches what road cyclists train indoors on. For serious indoor cyclists who want momentum and resistance feel rather than electronic preset programs, this is the right buy. Trade-offs: friction-pad maintenance, lower weight capacity than the YOSUDA YB001R, and the more basic console.
