## 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
