What to Compare Before Buying
- Wheel diameter: This model fits bikes with 26″ to 29″ wheel diameter. Match that range to the bike you plan to use.
- Floor space: The maximum footprint is 53″ x 18.5″. Check that area against your available workout space.
- Storage space: The folded size is 31.5″ x 18.5″ x 5.31″. Compare that with the space you have when the rollers are not in use.

Before You Decide
Confirm the bike’s wheel diameter, the footprint you can spare, and the folded size you want for storage. The no-power design also keeps the setup simple if you want a trainer that does not need an outlet.
