## Description

As our smallest mountain bike for girls, the Tess 20 has an important job: introducing the next generation of girls to some of the most fun available on two wheels. And it's definitely up to the task. We started with an ultra-durable steel frame to handle the punishment it's sure to Endure as your little one perfects her techniques. It's equipped with adjustable brake levers and a 6-speed trigger shifter that are easy for kids to use, and a derailleur Guard for protection. A suspension fork and wide tires add traction and control on rough pavement and dirt paths. This 02-1500030 fits riders 44"-54" Tall, aged approximately 4-9 years old.

Review: Great value and quality for the price, EASY assembly... instructions below! - Bought this bike for my 7-year-old daughter. It’s easy to focus on the negative reviews, but I found the assembly of the bike to be easy and the quality of the bike to be well-made. It is definitely on the heavier side for a 20” bike, which would make lifting it up onto a curb a slight challenge for a young child, but it does not affect riding. My daughter is flying on it with no issue. :) The gears have helped her keep up with her older sisters when we go up neighborhood hills. It's a rugged, sturdy bike, so she’s having a blast riding over curbs and bumps that she couldn’t do on previous bikes. It’s true: the instructions handbook wasn’t very helpful. It was a bit too wordy, didn’t have enough illustrations, and lacked clear easy-to-follow steps. So, I collected tips from fellow reviewers, watched a few videos, and consolidated instructions here as best I could: 1. After getting all the packaging off of the bike parts (which probably took the most time out of the whole process, haha), you can use the big box the bike came in as a stand to prop up the bike. Set the bike up right, resting on its back wheel… then, hang the front of the bike (which doesn’t have a wheel) over and into the big box. Your bike should be standing upright, supported by the box. 2. Now that the bike is standing upright, you can install the handlebars. Loosen the bolt on the piece that gets inserted into the rest of the bike. It’ll help it slide in easier. When it’s been inserted at the appropriate length, you can tighten the bolt to secure the connection to the rest of the bike. You may notice your handlebars look misaligned - like the brakes are in a weird position. DO NOT mess with the brakes themselves. To level out the brakes, simply loosen the bolt on the front of the handlebars. Once loosened, turn the handlebars until the brakes are aligned with the level of the rider’s arms/wrists/hands. Once level, you can tighten that front bolt. (See photos) 3. Next install the seat. (See photo) 4. Now that the seat is installed, flip the bike upside-down to install the front tire. (You no longer need the big box) You’ll need to loosen the brake wire to make enough space for the front bike to slide into place. (See photo) Also, you’ll need to temporarily remove the nut and washer from both sides (these will be secured in the next step). Once the brake is separated widely enough, insert the front wheel into place. Secure it into place by putting the wash and nut back on. The washer has small point end that should be inserted into a tiny hole on the bike frame. (See photo) Now, you can adjust the brake wire again to an appropriate length and tighten it accordingly. 5. Attach foot pedals. They have L and R stickers for left and right. The R pedal goes on the side with the chain and gears. (See photo) 6. Install the ‘gear protector’ rail (looks like a water bottle holder) over the gears on the right side of the rear tire. (See photo) 7. I ordered a separate kickstand that would fit a 20” bike. Install was pretty straightforward. (See photo) 8. Finally, install the front white reflector onto the handrails and the red rear reflector under the seat. 9. Adjust the seat height so that the rider’s legs are almost fully extended, but with a slight bend in the knees. When seated, your rider might be on her/his tiptoes when standing on the ground. You’re done! Hope this helps - happy riding!
Review: Awesome all-around bike for kids - Recently purchased this bike for my 7-year-old Daughter’s birthday. We have had a lot of great experiences with Diamondback bikes before; high quality components, all-around solid build. This bike is no different. As her first suspension bike, my daughter loves riding over rocks on trails, a total confidence booster! We weren’t sure if a 20” bike was too big for her so we used the Diamondback Live Chat feature on their website. It was very helpful in picking the right bike and size, highly recommend the service if you have any questions. Shipping was fast (2-day Prime) and the bike was a breeze to assemble, especially since the box comes with all the tools you need. Our favorite part is the 6-speed gears. It’s our daughter’s first bike with gears and she is way faster riding now! The trigger shifter was very easy for her to learn and they shift very smoothly. If anyone is looking for a kid’s bike this Christmas season, I highly recommend this bike + a kickstand
