Race kids mountain bike

For a short time you can get a high end $600 kids bike for only $199, get one before they are gone. Quantities are limited at this price.
In 2013 Dr. Yan was looking for a kids mountain bike for his children. Unfortunately the only options he found were of inferior quality, hence he decided to design his own.
We offer the bike with two forks options a rigid lightweight aluminum fork for smaller kids ( 5 - 9 yrs old ), and a suspension fork with a taller frame for older children, or smaller kids that do not have enough strength to handle rough trails. The rigid aluminum fork with low tire pressure will work very well for lighter children, since their weight will not create enough force to engage the suspension fork. Additionally it teaches your child to pick a smooth line in the trails, which is very important. Older kids will love to fly down single track with the quality suspension fork, the fork allows kids with minimal strength to handle impact from roots and rocks. Giving them the opportunity for experiences they would otherwise never have. 

Bikes are not easy to fit for adults, can you imagine how hard it must be to fit a growing child in which all measurements change? To allow for easy fitting adjustments we use an angle adjustable stem. As your little one grows you can loosen the stem bolt to increase the virtual top tube length, hence a custom fit is always easy. You will not find this feature on any other quality kids bikes.

We use top quality V brakes paired with machined sidewall rims. Slick rims allow the brakes to slip, machined sidewalls have a rough surface for the brake pads to create more friction. This bike stops FAST! If that's not enough we use standard 6 bolt disc hubs with quick releases on the front and rear, so you can run disc brakes without replacing the wheels, so it's easy to upgrade.

The 9sp drivetrain is racing quality, with a smooth shifting rear dérailleur. A master link chain means it can be removed without tools for easy cleaning and maintenance. A cassette with chain ramps allow for smooth shifting, and trigger shifters are easy for small hands to shift with minimal force. Since the bike has 20" wheels you will not need any more gears. The low gear is 28 gear inches, which means it will allow your child to climb like a goat, and with a top gear inch of 84 it will descend at over 20mph. However for kids that need more speed we include a braze on for a front dérailleur, you can add a second chainring to the stock crankset, or try a triple crankset for 27 speeds. We recommend you stick with 9sp or go to 18sp if necessary.

This bike can turn into a fast road bike by replacing the stock tires with 1.25" wide tires. Dr. Yan's daughter raced the 7.03 triathlon series with a production sample. She won the 2014 series and consistently finished first on the bike and swim portions in the 2015 series. In short this bike is ready for anything, rough off road trails & fire roads are a breeze, and it can conquer even the fiercest kids triathlon courses. Our price is over $200 less than our weaker spec'd competitors models.

    Great Bike for Kids

    Posted by BarneyPok on Sep 4th 2017

    My son loves this bike, and it costs less than half the price of Specialized and Trek kids models
