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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great kids bike *by D***Y on February 15, 2026* I really like the sturdiness of this bike. Gave it to kiddo two months ago and she rides it daily. One of her favorite play time activities. The kickstand is sturdy, gears shift easily and the broad tires help with out uneven terrain. ### ⭐⭐⭐⭐⭐ Mountain Bike *by D***N on September 5, 2025* We bought this Bike for our Granddaughter and she loved it! Easy to put together! And shes in love! ### ⭐⭐⭐⭐ 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. ## Frequently Bought Together - JOYSTAR 20 Inch Mountain Bike for Kids Ages 7-12 Year Old, 3-Inch Wide Knobby Tires, 7 Speed Shimano Drivetrain, Disc Brakes, Fat Tire Kids Bicycles for Boys Girls - RoyalBaby Kids Bike EZ Freestyle Training Free Balance to Pedal Easy Learning Bicycle, 12-18 Inch for Toddlers to Big Kids - Kids Bike Helmet, Adjustable and Multi-Sport, from Toddler to Youth, 3 Sizes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/451458581-joystar-20-inch-mountain-bike-for-kids-ages-7-10](https://www.desertcart.sn/products/451458581-joystar-20-inch-mountain-bike-for-kids-ages-7-10) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-25*
