What to Compare Before Buying
- Rider fit: Check that the 20-inch bike is an appropriate fit for the intended rider; the stated age range alone does not establish fit.
- Storage space: Compare the folded dimensions of 840 × 350 × 630 mm with the space available.
- Equipment: Consider whether the 7-speed gear system, mechanical disc brakes and suspension fork match your preferences for the intended rides.
Before You Decide
Check the intended rider’s fit, the folded storage space and the bike’s stated equipment. The source gives folded dimensions but no rider-height or fit measurements.
Carrying It on a Commute
If your journey involves lifting the folded bike through a doorway, onto a train or into a vehicle, check its weight and the clearance along your route as well as the folded dimensions. Those measurements do not indicate how easy the bike is to lift or carry.
