## Questions & Answers

**Q: I cannot find any information about how to raise the handlebar on this bike.  Anyone know how to do it?**
A: Take a wrench on the bolt that holds the handlebar in place. Lefty Losey righty tightly. Losen the bolt, pull up and tighten the bolt, and be sure to keep the handlebars straight and true with the front tire. The handlebars have little play, but you can bring them up.

**Q: How do you adjust the handlebars to go up?**
A: On the littlerock version you can't adjust the handle bars. Because of this we had to return and get the Pluto version.

**Q: How much does this bike weigh??**
A: Tho I’m not sure on exact weight my wife has no issue picking it up with one hand and loading it in the back of our truck

Great product.

### ⭐⭐⭐⭐⭐ Great kids bike

### ⭐⭐⭐⭐ Struggle Assembling Bike
*by W***A on December 25, 2025*

I bought this bike for my little brother that lives a couple of states away from me, and my mom had a difficult time putting the bike together since it came with NO INSTRUCTIONS!! We even tried going on the website to find a demo of how to put it together and absolutely nothing on this bike, I was not going to pay an extra 180$ to have it pre assembled. At least give people instructions on how to build it, if you’re going to charge double the price to have it pre built. He loved it regardless, but it sucked not being able to help my mom more when building the bike. Will not be buying from this brand again, they obviously want you to struggle if you don’t buy the pre assembled.
