## Questions & Answers

**Q: Are the bike pegs removable? My son wants to use it as a dirt jumper.**
A: The bike we received didn't have the pegs assembled.  As a matter of fact the pegs aren't that good. Slippery for shoes.

**Q: how much does the bike weigh in total**
A: Hi there! This model is roughly 32 lbs. when fully assembled. Thanks for reaching out!

**Q: My son is 7yr old and is 4'3" will the L20 fit him?**
A: For the most part, yes, it'll fit him. For those wanting to be technical no not all BMX bikes are a universal fit for all ages, but that's, in part at least, why there's an adjustable seat post to them, quite simply. Also, a quality BMX bike should be able to grow with a kid and accommodate his size as he grows. It might seem as simple as adjusting the seat post, but most of the youths tend to start off riding in a sitting position and grow to ride standing up more often than not, so adjusting the seat post height really becomes a non-issue soon enough. But another simple method is, have the kid straddle the bike. If the top tube is bumping his crotch, the bike is too big for him and vice versa.

**Q: Is the legion L20 a good fit for a teenager?**
A: For an L20 model I would suggest a rider 4' 8" – 5' 4" in height. That can be a wide range of ages that's generally 8 and up. Thank you, Nicole
