Description

We build a lot of Pro sized custom race bikes here at LUX, so we thought it was a perfect opportunity to piece together a smaller bike like this Meybo Holeshot Junior Custom that brings together the best brands to create the coolest junior race rig. A bike that you can pick up for young rider and head straight to the podium (or the sprocket equivalent) straight off the floor.

This little rocket ship is based around a Meybo Holeshot Junior frame with a 18.7" top tub and finished in two tone race winning red.

Then we started grabbing stuff off the shelves to build it out. BOX carbon forks, SD cranks with HT pedals that are the perfect size for little feet, SD bars

Then there's the wheel set! A Onyx Pro HG disc hub out back will handle all the horsepowers, with the front Onyx Helix 10mm hub shaving some weight. Onyx has been synonymous with performance and reliability for years now, and these ones are laced to Spectre's new carbon rim. Internally known as the Battlesnake rim, the V2 Spectre rim has a subtle, unique design and is tough enough to withstand everything a young shredder can throw at them!

Pulling you rug rat up after the finish line is a set of Magura disc brakes that have an adjustable lever for reach so that you can dial in the breaking for those small hands. This lever can be swapped to the left, so no sweat there on your kid having to relearn braking technique with a different hand.

All in all, this Meybo looks amazing in our showroom, but it would look even better out on the track and in your bike room at home. So if you are looking for one of the best Junior custom race bikes we've built, hit the add to cart button and we'll send it!

Assembly information

Your race bike ships mostly assembled in the box. Finishing it takes most people 10 to 20 minutes with basic tools, and the video above walks through every step.

Fit the handlebars and line them up with the front wheel
Fit the front wheel, pedals and seat post
Spin the rear wheel and check the rotor runs clear of the calliper
Check the brake and tyre pressure before the first ride

Disc brakes: keep your fingers off the rotor and pads, because oil from your skin contaminates the braking surface and takes the bite away. If the rotor rubs, loosen the two calliper bolts, squeeze the lever, then tighten them again with the lever held on. Bed the brake in with a few firm stops before you race it.

Tools: Allen key set and a 15mm spanner for the pedals. Check your axle hardware, since race bikes vary between bolt-on nuts and a thru-axle.

Rather have it done? Ask us about extra assembly before you order, or any local bike shop can finish the build for a small fee.

Heights overlap between bike sizes on purpose. If you fall in two size categories, a growing rider new to racing is usually better suited to the larger bike, a experienced rider who wants the bike to more responsive should err on the smaller size. Some brands label the Pro size Pro L, with the same fit.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark. Just don't guess their height either, you know how fast they can grow!

Here are some tips

Between two sizes and still growing? Take the larger size, but make sure you check the top tube length of the bike. The length of top tube for a given size (Expert XL as an example) can vary up to a half inch or more across brands. Most Expert XL frames are 20", but we've seen them as long as 20.7"
Experienced racer and wanting the bike to be more responsive? Take the smaller size. You want the bike to be "under you", not a stretch to the bars and cranks.
Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Still not sure? We're the experts and size bikes for riders every day of the week. Our team has decades of experience between them and will help you decide which bike is the right fit based on rider height and racing experience.
