Atom All-Terrain Longboard Review: 100 mm Wheels Explained

Most longboards are built for smooth pavement. The Atom All-Terrain Longboard is built for everything else: cracked streets, rough tarmac, patched cycle paths and hard-packed tracks.

Here is the short answer. The Atom All-Terrain is a low, wide longboard on very large 100 mm wheels, made to roll over surfaces that would stop an ordinary board. It is a specialist. On bad roads it makes sense. On smooth ones it is heavier and slower to get moving than a normal longboard.

This review also explains what all-terrain does and does not mean, because the phrase is easy to misread. One thing to be clear about. This is a spec-based review. We have not ride-tested the board. Everything here comes from the specifications on its Amazon listing, checked in October 2026, and from what those specifications normally mean on the road. Here is how we review products.

Quick verdict: who is the Atom All-Terrain for?

The question to ask is simple. What are your roads like? If they are smooth, you do not need this board. If they are rough enough that a normal longboard is unpleasant, this is the kind of board that fixes it.

What all-terrain really means

All-terrain is a strong phrase, so it is worth being precise about it.

This board is not a mountainboard. Mountainboards have air-filled tyres and foot bindings, and they are ridden down grass and dirt slopes. The Atom All-Terrain is a longboard with unusually large, solid urethane wheels.

What those wheels do is widen the range of hard surfaces you can ride comfortably. The listing describes them as a blend of on-road speed and off-road traction.

That table is a general guide to what large, solid wheels can do. It is not a test result.

Why does wheel size make such a difference? A wheel has to climb over every bump it meets. A small wheel hits a crack at a steep angle and can stop dead. A large wheel meets the same crack at a shallower angle and rolls over it. The bigger the wheel, the smaller the bump feels.

A bigger wheel does not make a rough road smooth. It makes the rough road matter less.

Atom All-Terrain specs at a glance

What the specs mean on the road

The 100 mm wheels

These are the reason the board exists. A normal longboard wheel is about 70 mm across. These are 100 mm, and 65 mm wide. That is a very large wheel.

The benefits are a smooth roll over rough ground and a lot of momentum. Once a wheel this size is moving, it keeps moving. The hardness is 78a, which is soft, so the wheels also absorb vibration.

The costs are weight and effort. Large wheels are heavy, and it takes more of a push to get them up to speed. They also raise the board. That is why this board uses a drop deck, as the next section explains.

The drop deck

A drop deck is shaped so that the standing area dips below the level of the truck mounts. On this board it does an important job. It cancels out much of the height that 100 mm wheels would otherwise add.

The listing says the deck keeps your centre of gravity low for pushing. That matters more than usual here. Without the drop, you would be standing a long way off the ground, and every push would be hard work.

The 10-inch width

At 10 inches, the deck is an inch wider than most budget longboards. That gives a broad, stable base, which is welcome on uneven ground. Riders with large feet will appreciate it. Riders with small feet will find it takes a bigger lean to turn.

The trucks

The trucks are reverse kingpin with a 50 degree base and 7 inch hangers, which is the standard longboard arrangement. The listing mentions heat-treated chromoly axles and grade 8 kingpins. In plain terms, the axles and main bolts are described as strong, which is sensible on a board meant for rough surfaces.

The bearings and grip tape

The bearings are listed as rubber-shielded. Shields help keep grit out, which matters if you ride dusty paths. The ABEC 9 rating itself tells you very little.

The grip tape is listed as super coarse 46 grit. Standard grip is about 80, and a lower number is rougher. Coarse grip holds your shoes firmly when the board is bouncing over rough ground. It also wears shoe soles faster.

Is it the right size for you?

Here is how a 39 inch board lines up with our size chart.

Width. A 10 inch deck suits shoe sizes from about US men’s 10 upward best.

Weight. The listed limit is 220 lb. Rough ground puts extra load on a deck, so leave a generous margin.

Carrying. At a listed 10 lb, with big wheels, this is an awkward board to carry. It is best for riding from your door.

Loaded Fathom (33 in)

Best for: Riders who want very large wheels on a board built for commuting and distance.

The Fathom mounts its trucks on brackets beyond the ends of the deck, so the platform sits very low. Loaded pairs that with very large wheels and describes the result as easy to ride and built to hold commuting speeds.

• Length 33 in
• Width 9.5 in
• Deck 8-ply maple, slight camber, bracket mounting
• Trucks Paris 150 mm
• Wheels 105 mm or 85 mm Orangatang

• Width 9 in
• Deck Maple laminate, drop deck
• Trucks Reverse kingpin, 245 mm axles
• Wheels 70 x 51 mm
• Bearings ABEC 9
• Listed weight limit 220 lb

✅ Why it works

• The very low platform saves your legs on long pushes.
• A 41-inch deck on wide axles feels steady.
• Grippy 80S grip tape is listed.

⚠️ Keep in mind

• The listing does not give a clear wheel hardness.
• The listed weight limit is 220 lb.
• A very low deck has less ground clearance over kerbs and speed bumps.

All-terrain board or bigger wheels on a normal board?

A fair question is whether you could simply put larger wheels on an ordinary longboard. Sometimes you can, up to a point.

For many riders, the middle option is enough. Wheels of 75 to 85 mm make a big difference on poor pavement and keep the board lighter.

The All-Terrain makes sense when your routes are bad enough that even those are not enough, or when you want to mix pavement with hard-packed paths. Wheels of 100 mm will not fit under most normal decks without touching, so a board designed around them is the practical way to get them.

How to ride on rough surfaces

Big wheels help a great deal. Good habits help just as much.

1. Keep your knees bentYour legs are the suspension. Soft knees absorb what the wheels do not.
2. Stay looseA stiff body is thrown about by bumps. A relaxed one rides over them.
3. Look aheadScan the surface a few metres in front of you and pick the smoothest line.
4. Keep your speed downRough ground gives less warning and less grip. Ride at a pace where you can stop.
5. Cross obstacles square onMeet cracks, edges and rails as close to a right angle as you can, so a wheel cannot be caught.
6. Step off when in doubtLoose gravel, wet grass and deep cracks are reasons to walk.

Looking after a board used off pavement

Dust and grit are hard on bearings. If you ride dirt paths, clean the bearings more often than you would on a street board, and wipe the board down afterwards. Avoid water and mud. Shields slow dirt down, but they do not make bearings waterproof.

Setting it up out of the box

A complete board arrives assembled, but a five-minute check before your first ride is always worth doing.

1. Check every boltMake sure the eight truck bolts are snug and nothing rattles when you shake the board.
2. Spin each wheelEach wheel should spin freely for several seconds. If one stops quickly, loosen its axle nut a quarter turn.
3. Set the truck tightnessStand on the board and lean. If it barely turns, loosen the large nut on each truck a quarter turn. If it feels wobbly, tighten it a quarter turn.
4. Start on flat groundFind a smooth, empty space. Practise standing, pushing gently and foot braking before you go anywhere.
5. Give it a couple of weeksNew bushings and bearings loosen up with use. The board will turn and roll more freely after a few rides.

If something is clearly wrong, such as a warped deck, a wheel that will not spin or a cracked part, do not ride it. It is much easier to return a board that has not been used.

Common mistakes (and how to fix them)

Looking after your board

A longboard needs very little maintenance, but a few habits make it last much longer and ride much better.

• Keep it dry. Water rusts bearings and damages wooden decks. If the board gets wet, dry it and spin the wheels.
• Check the bolts. Vibration loosens truck bolts and axle nuts over time. A quick check every few weeks is enough.
• Clean the bearings when the wheels sound gritty or stop spinning freely.
• Swap the wheels around now and then, so they wear evenly.
• Replace worn bushings. Cracked or squashed bushings make a board feel sloppy, and new ones cost very little.
• Store it indoors. Heat, cold and damp all shorten the life of a deck.

Key terms in plain English

Longboard listings use a lot of jargon. Here are the terms used in this guide, explained simply.

Frequently asked questions

Is the Atom All-Terrain Longboard any good?

On its specifications, it is a well-equipped board for rough hard surfaces. It has a 39 by 10 inch maple drop deck, 100 mm 78a wheels, reverse kingpin trucks and coarse grip tape. It is heavier than a normal longboard and is best for riders whose routes are rough.

Can you ride an all-terrain longboard on grass?

Only on short, dry, firm grass, and with effort. Solid urethane wheels of 100 mm are made mainly for rough pavement and hard-packed paths. Long grass, mud, sand and loose gravel need a mountainboard.

What size wheels does the Atom All-Terrain Longboard have?

The listing gives the wheels as 100 mm in diameter and 65 mm wide, with a hardness of 78a.

What is the weight limit of the Atom All-Terrain Longboard?

The Amazon listing gives a load capacity of 220 lb.

Is an all-terrain longboard good for beginners?

It is stable, low and wide, and the listing marks its skill level as all. It is also heavy and takes more effort to push. A beginner on smooth roads will find a normal longboard easier.

Is the Atom All-Terrain right for you? A checklist

This is a specialist board. Make sure you need what it offers.

• My usual routes are rough, cracked or patched.
• I want to ride hard surfaces, not mud, sand or long grass.
• I am happy with a heavier board that takes more effort to push.
• I do not need to carry it far.
• I weigh comfortably under 220 lb.
• I have larger feet, or I am happy with a wide deck.
• I have a helmet.

The Atom All-Terrain Longboard answers one question well: what do you ride when the roads are bad? If that is your problem, 100 mm wheels are a real solution. If your roads are smooth, a lighter, simpler board will make you happier.
