### ⭐⭐⭐⭐ Bike was not inspected so it had some bad flaws
*by J***5 on July 31, 2025*

The good : Nice sturdy bike, looks cool, and easy to put together. The Bad: The wheels are out of round they wobble but, not to bad. The brake cable was wrapped around the forks was bent and the wire is exposed. Last the instructions doesn't show you how to fold the bike nor was back of the booklet filled out which should show when it was inspected and who inspected it. They might of found the flaws I noticed.
