## Description

desertcart.com : Dynacraft Magna Gravel Blaster 12" Children's Bike : Sports & Outdoors

Review: Great First Bike - It was a Christmas gift, and the child loved it. It was fairly easy to assemble. We had a blow out of the inner tube overnight, but the seller sent a new one right away.
Review: A Happy Birthday - I bought this bike for my grandson's 5th birthday. His favorite color is yellow so he loved it. It was easy for his Dad to put together. I live 3 hours away from them so I had it delivered at their house. That worked out just fine. Thank you!

## Questions & Answers

**Q: My grandson will be turning 5 next January will this bike be Ok for him? He has never had one. This will be his first bike**
A: My boys got them at 4.5 years old, the seat is adjustable and it is an easy first bike.  But if your grandson is tall, then he might outgrow it in a year.  My 6 year old daughter, on the shorter side, uses a 16 inch wheel bike which will last her a couple of more years.

**Q: Do you think this is a good first bike for a 3 yr olds b'day? We thought this might be better than a trike, but I'm not sure.**
A: YES! 100%.  We love it and got ours for our 3 year old.  He is 4 now and still rides it.  I'd say it has another year at least worth of riding! We love this bike. It's cute and made well.

**Q: Is the seat adjustable?**
A: Yes the seat is adjustable up or down. You just have to loosen the bolt a little and it moves then tighten the bilt back up.

**Q: How am I supposed to secure the handle bar?  I tightened the bolt at the top with Allen wrench but it didn't do anything.**
A: i don't know i returned the one i bought because it was banged up.

### ⭐⭐⭐⭐⭐ Solid bike
*by B***N on January 18, 2024*

Fairly easy to assemble although instructions were for multiple models so was a bit confusing. And you should be aware you will need an air pump because tires are not inflated. Past that it is good bike.
