From crate to trail
Assembly made easy
Your machine shows up mostly built. A little final assembly gets you riding — or let the warehouse handle it for you.
Option 1
Factory Package
Ships in the crate, 80–95% pre-assembled. You handle the final steps — usually bars, mirrors, fluids, and a charge or fuel-up. The most affordable way to get your machine.
Option 2 · gas dirt bikes
Assembly Service
On our gas dirt bikes, you can add the Assembly Service option right on the product page — the machine is assembled and checked before it ships, so it arrives ready to ride with far less work on your end.
Electric bikes arrive ready to ride. Our electric models (KOOZ, Freego, 79Bike, and X-PRO electric) come almost fully built — usually just the front wheel, handlebars, and a few bolts, then charge it up and go. They don't need the paid Assembly Service, so you won't see that option on those bikes.
Electric dirt bikes
Out of the box, step by step
Electric dirt bikes ship in a protective box with the front wheel and handlebars off— that's how they survive freight. Setup is basic hand tools and about 30–60 minutes, and a second set of hands makes a couple of steps easier. Here's the typical order:
- 1Unbox and inspect. Cut the box away carefully (don't slice toward the bike), remove the padding, and lay out the parts and hardware. Check everything against the manual's parts list and look over the frame for any shipping damage before you start.
- 2Install the front fork / front wheel. Depending on the model, slide the fork tubes into the triple clamps to equal height, then seat the front wheel on its axle. Snug the axle, then tighten evenly to the manual's spec. This is the step where a helper is worth having.
- 3Attach the front brake. Mount the front brake caliper to its bracket and confirm the disc spins freely through it. Squeeze the lever — you want firm, even bite before the bike ever moves.
- 4Mount the handlebars. Set the bars into the clamps with the controls facing forward, center them, and tighten the clamp bolts evenly (a little at a time, alternating). Don't overtighten.
- 5Go over every bolt. Axles, bar clamps, brake hardware, foot pegs, and anything the manual lists. Machines vibrate — this ten minutes is what keeps everything where it belongs.
- 6Set tire pressure. Shipping pressure is rarely riding pressure. Air both tires to the range printed on the sidewall or in the manual.
- 7Charge the battery fully. Give it a complete first charge with the included charger before the first ride — it's the right start for battery health.
- 8Find the speed selector. Most kids' electric models hide a 1-2-3 speed dial inside a small covered box on the bike — flip the lid open and it's right there. It's easy to miss, and it (not the key) is what sets the bike's top speed. Set it to 1 for a new rider and bump it up as their skills grow.
- 9Pre-ride check. Brakes firm, bars tight, wheels true, throttle returns on its own. For young riders, start on speed 1, gear up (helmet always), and keep the first rides supervised in an open area.
Three pro tips while you're in there
- Grease the axle.A light coat on the shaft before it goes through the wheel — and a thin film on the threads — stops corrosion and keeps the nut from seizing, so future service is easy. Snug the nut to the manual's spec (greased threads tighten further at the same effort, so firm — not gorilla-tight). ⚠️ Keep grease completely off the brake rotor and pads — even a fingerprint can ruin braking. Wipe your hands before touching the brake, and clean any stray grease off the rotor with brake cleaner or rubbing alcohol.
- A drop of blue threadlocker on small bolts (fender, bracket, and accessory hardware) keeps vibration from walking them loose. Blue (medium/removable) only — never red — and skip it on nylock nuts and anything you'll adjust.
- Re-check every bolt after the first ride. New hardware settles in the first half hour of riding — a quick once-over with the wrenches afterward is the single best thing you can do to keep everything tight for good.
Check the box for your model's manual and follow it where it goes deeper (torque specs, charging details). Fair warning: on imported machines the printed manual can be thin or roughly translated — that's exactly why this guide exists, and why we're here. Stuck on a step? Reach out and we'll walk you through it, on email or a call.
Finishing the job yourself
Most final assembly takes basic hand tools and an hour or two. A typical checklist looks like:
- • Mount and align the handlebars and mirrors.
- • Check and tighten key bolts (axles, controls, foot pegs).
- • Add fuel/oil or fully charge the battery per the manual.
- • Set tire pressure and test the brakes before your first ride.
Follow the manual where your machine includes one — and where it's thin (common on imported bikes), lean on the step-by-step guide above or just ask us.
