Bottom line
The Tern BYB is a 20" folding bike available in two builds, S11 and P10. The more expensive S11 has commuter accessories; the cheaper P10 is simpler and lighter. Experts and owners praise the bike's compact design, balanced handling, comfortable riding position, and quality Shimano drivetrains. Additionally, the 20" wheels deliver a fast and stable ride compared to 16" alternatives. Testers say the BYB offers excellent urban practicality, but it's expensive and has a relatively complex folding process. Some reviewers also complain about rough welds and inelegant cabling. But overall, the Tern BYB seems a good folding commuter option.Expert Reviews
