Zukka 20 inch Girls Mountain Bike 7 Speed Aluminum Alloy Frame Bicycle for Kids Girls in Pink

I bought this bike for my 6 yr old girl and she is in love with it! It's still a tiny bit big for her, but once she gets rolling, it's fine. She is 46 inches tall. It's well built and looks so cool! The shifting is so simple.

I was very impressed with the quality of this frame. I wanted a light weight aluminum frame for my child because we live in a hilly area. I was looking at bikes that cost twice as much for Al frame with the same Shimano 7-speed shifters, disc brakes, and suspension fork. I think disc brakes are a great idea for kids because they are very hard on the wheel rims. They inevitably get bent and then you'll have problems with caliper brakes rubbing on the bent rims. You'll never have that problem with disc brakes no matter how bent the rims get. I didn't really need/want the front suspension fork. It adds weight and isn't really needed. But the kids definitely think they're cool! I'm very impressed with the rest of the components as well. The crank arms, seat post, and handle bar are also aluminum. I think the rims are as well. The only low quality component are the wheel hubs. They are simple cone and race bearings, not sealed bearings. But I couldn't see spending an extra $300 just to get sealed wheel bearings. You can even lower the handlebars by moving the spacers (there are 4) that separate the handlebar and the head bearing. Just move 1, or all 4 spacers so they are above the handlebar instead of below it. The frame is beautifully constructed and has a replaceable derailleur hanger. My daughter is thrilled with the pink color and the 7 speeds. It was easy to assemble, but I did have to adjust the brakes to keep them from rubbing (simple two bolts on each brake caliper to make the adjustment). I also needed to adjust the shifter cable. Again, that's very easy if your familiar with derailleurs. And these adjustments are to be expected with any bike assembly. But I was surprised at the very large friction in the front wheel hub. I didn't expect I would have to adjust that. But I had to loosen the nut on the front axial and unscrew the cone slightly, then retighten the nut in order to get the wheel bearings to roll smoothly. When I was done the wheel would spin for more than a minute before coming to a stop. This bike is an incredible bargain. I didn't see any other manufacturer offering an aluminum frame and disc brakes at this price.

I live on the Metropark where there is a bike trail that has some hilly terrain. We purchased 2 of these for our 2 grandchildren. They are a boy 6 and a girl 8 years old. The ability to shift into first gear really made it easy for the kids to pedal up hill. We had our first ride yesterday. Both kids mastered them with ease.
