You've been asking for a 20" bike from Trailcraft, and the time has come for our Blue Sky 20 to meet the young riding world! If you want to give your kid the absolute best 20" proper mountain bike to create a life long riding partner from the earliest possible stage - this is the bike. 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. 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. Next level big-kid performance is achieved with high-quality top shelf level components and category-leading bike weights. Hang with your big bro or sis on this 20" machine - because it is a machine, it's not just another heavy 20" kids bike!
Weights starting at just 19 pounds WITH suspension fork, lock-on grips, pedals, chainstay/seatstay protectors.
All of our bikes are assembled in Fort Collins, Colorado from the bare frame up. This means you get to configure the bike you want in three color options, two build level options and two chainring size options to best suit your local terrain. Vee Crown Gem 2.25" tires are a confidence-inspiring width (they are monster 2.25's!) and a true "Tubeless Ready" folding tire. Rims come taped and are tubeless ready - we can set them up tubeless for you if you'd like to be about 250 grams lighter from the very start. Just specify "tubeless please!" in the notes at checkout.

Want to go a bit more custom or full custom on this build? Contact us! We are a small family business focused on building the best kids mountain bikes possible. We truly geek out on this stuff, just see our Instagram page for some of what we are doing as well as our custom builds page. We bring our frames in from Taiwan (un-assembled/not built) and we build each bike per order in Fort Collins, Colorado with US labor. Since we don't import "complete bike in box from Asia" like pretty much everyone else does, we maintain a high quality control from installation of headset, bottom bracket, and even putting the derailleur hanger on frames here in the US. You can be proud to tell your kids they have a unique bike which was truly built to order from the frame up!
See The Bike Dads Blue Sky 20 Review for a great video review.
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 starts in the low 19 pound range with the Pro Deore model. Low bike weights are achieved through higher quality component selection. Small touches like our new lightweight 127mm Trailcraft aluminum spindle direct mount cranks (with your choice of 28 or 30 tooth narrow-wide style chainring) is just one part we spec as an example which helps keep weight as low as possible.
Blue Sky 20 Pro Deore model get our Stans Crest MK3 Custom 1150 gram wheelset. Superlight 370 gram hubs laced to 20-inch Stans Crest MK3 rims are taped and ready for sealant. Ashima 85 gram 160mm rotors a lightweight stoppers!

- Rotors selection is one of the items often overlooked by other brands 20" bikes, our goal and spec selection is to keep wheel rotational weight as low as possible. The super low rotational weight of both wheelsets is very important to young riders just starting out, or more experienced riders trying to get to the next riding level. Both wheelsets also feature Vee Crown Gem Tubeless Ready 20x2.25" tires. These tires have a folding bead and have a great tread design which excels in most conditions. Their 2.25" width actually measures to be a true 60mm or 2.36 of confidence inspiring rubber without the "PLUS" sized weight you see with other brands!
TC30 air sprung suspension 80mm fork! This is the lightest 20" fork available with high mod carbon/alloy lowers, hydraulic lockout and preload adjust. Our own TC30 20" fork (combined with the BIG tubeless tires) really works and smooths out the choppy terrain for more control while fighting off fatigue. This allows longer rides with your young rider!
