HKM-8862547 49cc 2-Stroke Gas Mini Dirt Bike for Kids with Front and Rear Disc Brakes Off-Road Knobby Tires and Pull Start
HKM-8862547
A 49cc Dirt Bike for Kids
The HKM-8862547 is a gas-powered mini dirt bike built around a 49 cc two-stroke engine and sized for young riders. The welded steel frame carries the engine low, a telescopic fork leads the front wheel and a coil spring shock works under the seat. Disc brakes sit at both wheels, and knobby tires take on dirt, grass and gravel. The engine starts with a pull rope and feeds an automatic clutch and chain, so there are no gears to shift. Number plates front and side, a padded seat, a crossbar pad and a side stand finish the bike.
Key Features
Six details that define how the HKM-8862547 is built and how it rides.
Disc Brakes, Both Wheels
A disc sits at the front wheel and a second disc at the rear, so braking splits across both ends instead of loading one hub. The levers sit on the handlebar within a short reach of young hands.
49cc Two-Stroke Engine
The 49 cc two-stroke engine mounts low in the steel frame, keeping the center of gravity near the ground. It runs on gasoline premixed with two-stroke oil at 25:1 and starts with a pull rope.
Automatic Clutch, Chain Drive
An automatic centrifugal clutch feeds the chain drive, so the bike rolls away from a stop without any gear lever. A young rider works only the throttle and the two brake levers.
Fork Up Front, Shock at the Back
A telescopic fork takes the hits at the front wheel while a coil spring shock works under the seat at the rear. Together they keep the knobby tires tracking over dirt, grass and gravel.
Knobby Off-Road Tires
Deep-lug knobby tires wrap both wheels and bite into loose ground. The tread is the difference between riding a dirt line and walking one, on sand, dirt and wet grass alike.
Ride-Ready Details
A padded seat sits low over the engine, a crossbar pad covers the handlebar, number plates ride front and side, and a side stand holds the bike upright between rides.
Overview
A 49cc two-stroke mini dirt bike with disc brakes at both wheels.
The HKM-8862547 is a small-displacement dirt bike for young riders. A 49 cc two-stroke engine sits low in a welded steel frame and sends its power through an automatic clutch and a chain, so the bike moves away from a stop on throttle alone. A telescopic fork leads the front wheel and a coil spring shock works at the rear, while disc brakes at both wheels handle the stopping. Knobby tires carry the bike across dirt, grass and gravel, and the pull starter means a session never waits on a battery. Number plates at the front and sides, a padded seat and a side stand complete the bike as delivered.
Disc Brakes at Both Wheels
Each wheel slows through its own disc brake.
Each wheel slows through its own disc, so stopping does not ride on a single hub. The levers sit within easy reach on the handlebar, and both discs keep working lap after lap on loose ground.
Full Specifications
What it runs, how it stops and what it carries.
Engine, Frame and Suspension
How the 49cc engine and the long-travel suspension work together.
The HKM-8862547 runs a 49 cc two-stroke engine mounted low in a welded steel frame. Power leaves through an automatic centrifugal clutch and a final chain, so the bike picks up from a stop on throttle alone and never asks for a shift. A telescopic fork handles the front end and a coil spring shock carries the rear, giving the tires room to work over roots and ruts. Stopping comes from a disc at each wheel, worked by levers on the handlebar. The engine burns unleaded gasoline premixed with two-stroke oil at 25:1, and the spark plug sits reachable for checks between sessions.

Why Choose the HKM-8862547
Six further reasons riders pick the HKM-8862547.
Built for Loose Ground
Dirt, grass and gravel are where knobby tires earn their keep. The fork and rear shock soak up the ruts, and the low-mounted engine keeps the weight down where it helps traction.
No Gears to Learn
The automatic clutch feeds the chain by engine speed, so a new rider only works the throttle and two brake levers. Nobody has to stall their way through a first lesson.
Nothing to Charge
The engine starts on a pull rope and runs on premixed gasoline at 25:1, so a session never waits on a wall outlet, and there is no battery pack to fade halfway through the afternoon.
Brakes at Both Ends
Front and rear discs split the braking work across both wheels, and the levers sit on the handlebar within a short reach. Staying composed into a corner starts with stopping power you can modulate.
Serviceable by Design
The chain, the spark plug and the air filter are all reachable with the supplied tool kit, so routine checks happen in the garage rather than at a shop counter.
Room to Grow Into
Up to 25 mph with adult supervision, the bike gives young riders a proper machine to learn throttle discipline on, sized down to a frame they can flatten a foot against.
Frequently Asked Questions
Quick answers about the HKM-8862547 mini dirt bike.
What fuel does the engine burn?
The 49 cc two-stroke runs on unleaded gasoline premixed with two-stroke oil at 25:1. Mix fresh in a clean can, shake it before pouring, and do not let mixed fuel sit for weeks, because the oil separates and the engine runs lean on stale mix. Fill the tank before the engine is hot, wipe any spillage off the plastics, and store the bike with the tank nearly empty between long pauses. A spare spark plug ships in the box, and a clean plug is the cheapest fix for a bike that cranks but will not catch.
How fast does the bike actually go?
Up to 25 mph (40 km/h) in stock form. Real speed moves with the rider's weight, the surface and how fresh the premix is, so expect a bit less up a grass slope and a bit more on flat packed dirt. The automatic clutch keeps the power predictable rather than peaky, which is what matters for a new rider. Set the first sessions on private land or a closed course with an adult watching, and let speed grow as throttle control does.
Does it have a gear lever?
No. The engine feeds an automatic centrifugal clutch, so power arrives as the revs rise and the bike rolls away from a stop without any shifting. There is no clutch lever, no stall at a stop, and no gear hunting on a slope. A new rider only manages the twist throttle and the two brake levers, which keeps the first hour about balance and braking rather than about finding neutral. The final drive is a chain, so tension checks belong on the service list.
How does the engine start cold?
With the recoil rope. Set the bike on its side stand and pull the rope in one smooth, full stroke rather than short yanks, letting it rewind between pulls. Most cold engines catch within a handful of honest pulls. If the bike was flooded by repeated pulling, wait a minute, then pull through with the throttle shut. A fouled spark plug is the other usual suspect, which is why a spare ships in the box, and a clean plug costs nothing to fit with the supplied tools.
What brakes does it have?
A disc at each wheel. The front lever works the front disc and the rear lever works the rear disc, both mounted on the handlebar within a short reach of young hands. Discs keep their bite when a drum would fade, which is worth having on a bike that ends every session at the same gate it started from. Practice stopping hard in an open, traffic-free area first, because stopping distance grows with speed and a loaded rider needs more room than an empty one.
Where is the bike meant to be ridden?
On private land and closed courses, with an adult present. It is not built or approved for public roads, so keep it off tarmac traffic entirely, and check local rules before the first ride because some areas restrict small gas-powered bikes beyond the road question. Flat, open ground without holes or wire is the right classroom. Gear up every time: a certified helmet, eye protection, gloves and closed shoes are the baseline for even a slow first session.
Quick Troubleshooting
Common HKM-8862547 issues and what to check first.
The engine will not start
Work through the cheap causes first. Confirm there is fresh premix in the tank, because stale mix is the most common no-start on a two-stroke. Pull the spark plug, check it is dry and light tan rather than wet or black, and swap in the spare from the box if it looks fouled. Pull the rope in full, smooth strokes rather than short yanks, since a half pull never spins the engine fast enough to catch. If the plug is wet, the engine is flooded: wait a few minutes, pull through with the throttle shut, then try again.
The engine bogs at full throttle
A two-stroke that hesitates when the throttle opens is usually being fed badly rather than broken. Start with the premix: oil that separated in an old can leans the mixture out. Next, check the air side of the engine, because a filter packed with grass dust after a dusty session chokes the intake exactly this way. If both look fine, check the spark plug color after a short run, since a wet, dark plug points at a fuel mixture that needs attention. Work one cause at a time and note what changed.
The chain skips under load
A skipping chain is a tension and alignment problem until proven otherwise. Check that the chain has roughly half an inch of free play at its tightest point, and adjust the rear axle adjusters evenly on both sides so the rear wheel stays square with the front. An over-tight chain strains the bearings and an under-tight one skips exactly under throttle. Lubricate the chain after every dusty session, and inspect the sprocket teeth while you are there, because hooked teeth will eat a fresh chain in return.
The brakes feel soft at the lever
Soft lever feel on a cable-worked disc usually means the cable has stretched or picked up grit. Check that the lever actuates the caliper fully at half travel, and take up the slack with the barrel adjuster at the lever before touching anything at the wheel. If the feel stays soft, check the disc face is clean and dry, because oily fingerprints from assembly or chain lube overspray will cut braking power noticeably. Bed new pads in with a series of firm stops rather than one panic stop.
The bike pulls to one side
Start with the tires, because uneven pressure across the two wheels steers the bike more than any rider input. Check both tires are at similar pressure, then check the rear axle nuts and the adjuster marks, since a rear wheel knocked out of square after a low-speed tip will make the bike drift. If both check out, stand in front of the bike and sight the front wheel to the handlebar, because a bar that took a knock in a fall can sit off-center. Anything bent is a replacement, not an adjustment.
The idle will not settle
Give the engine a real warm-up before judging the idle, because a two-stroke idles differently cold than hot. Once warm, if the idle sits too high, too low or hunts, turn the idle screw in small steps rather than large ones and let the engine settle between turns. A dirty air filter or an aged spark plug can mimic an idle problem, so rule both out before touching anything further. If the idle stays unstable after those checks, note the plug color and contact support rather than disassembling the carburetor on guesswork.

Important Safety Notes
Read these notes before the first ride in the HKM-8862547.
The HKM-8862547 is a gas-powered mini dirt bike that reaches up to 25 mph (40 km/h). Read the manual before the first start, and practice throttle control and both brakes in an open, traffic-free area until they feel routine. A certified helmet and eye protection belong on every ride, with gloves, closed shoes and long pants as the working minimum. Ride only within the rated load for a young rider with adult supervision, and keep the bike on private land or closed courses, never on public roads. Check tire pressure, chain tension and brake action before each session, and let the engine cool before refueling.
