The 20 inch bike is the one where bike weight matters!  Each frame is hand built in small batches with double butted 7005 aluminum tubing, super clean internal cable routing (no snags!), forged dropouts, and post-mount disc brake mounts both front and rear. Our Blue Sky 20 Rigid Christmas Build has real MTB tires, real components and is super lightweight.

We've made a handful of limited run Blue Sky 20 bikes at a sweet price point of $1199.00!  Three colors to choose, and we even have our new 127mm direct mount crankset with alloy spindle on this mini machine!

How come all the bigger kids get the cool lightweight bikes and the little riders are left with the heavy turds?  Well not any more!  Our Blue Sky 20 Rigid Christmas Build is here just in time to put under the tree. Parents have been asking for a 20" bike from Trailcraft, and the time has come for our Blue Sky 20 to meet the young riding world just in time for the big day - Christmas!  Our Pineridge 24 was the first premium high-performance bike to hit the market and putting more kids on the top step at the local races, and we are taking the same premium approach with the Blue Sky 20 with category leading components and weights.

This is a fun, playful, super flickable bike for all types of mountain bike riding.  Race it, take it to parks, or just have an awesome bike to trail ride with your family.  Hang with your big bro or sis on this 20" machine - because it is truly a machine, it's not just another heavy 20" kids bike!

Weights starting at 17.99 pounds WITH lock-on grips, pedals and chainstay/seatstay protectors after you set it up tubeless. Other kids bikes in the sub-20 pound range will spec skinny tires to try to keep weight low. Not Trailcraft, we have a monster tire and this bike is still pounds lighter than theirs. If your kid is about 40 pounds, this means they finally have a REAL 20" mountain bike with REAL components and REAL 20 x 2.25" tubeless ready tires (they actually measure to a 2.3666" on our calipers) to dreamcrush their local riding trails like they never have dreamcrushed them before.

Next level big-kid performance is achieved with high-quality top shelf level components and category-leading bike weights.
