## Questions & Answers

**Q: Does this bike come already assembled together?**
A: No. You have to assemble it yourself.

**Q: Do this bike have a stop handle to stop the bike**
A: No hand brake, just the coaster brake.

**Q: does the seat adjust on this bike?**
A: It adjusts, but with tools. No quick release on the seat post.

**Q: The age description is 12 years old. Will it work for an 8 year old?**
A: It would depend on her height. Our 10 year old uses her tip toes to balance on the bike. We have the seat all the way down too. Our daughter is 4'4"
