Atom B18-DX 2-in-1 All Terrain Street Electric Longboard Overview
The Atom B18-DX answers a question that every serious electric longboarder eventually asks: why choose between a street board and an all-terrain board when you can have both? The B18-DX ships with two complete wheel and pulley setups, 90mm street wheels for smooth pavement riding and MBS 100mm all-terrain wheels for gravel, grass, and dirt trails, and swapping between them takes minutes at home with basic tools. Commute to work on smooth 90mm street wheels during the week. Hit the backroads and dirt trails on 100mm all-terrain rubber on the weekend. One board, two completely different experiences.
Beyond the 2-in-1 concept, the B18-DX goes further with four distinct gear ratio configurations created by mixing its two wheel sizes with two different pulley sizes (60T and 48T). Gear ratio 1 (60T pulley, 90mm wheels) maximises climbing torque for steep terrain. Gear ratio 4 (48T pulley, 100mm wheels) maximises top speed, reaching 21 mph. The two intermediate ratios provide all-around performance optimised for different conditions. This level of mechanical customisation gives the B18-DX a depth of capability that fixed-configuration boards simply cannot match, and it introduces riders to the gearing concepts behind electric skateboard tuning without requiring any electronics knowledge.
Who Is the B18-DX For?
The B18-DX is built for experienced electric skateboard riders who want genuine all-terrain versatility and the mechanical engagement that comes with a board you can actually tune and configure. It is also the right choice for riders who live in environments where both paved commuting and dirt trail riding are regular activities, and who do not want to own two separate boards for those use cases. The four gear ratio system also makes it an excellent choice for riders who are curious about electric skateboard mechanics and want a hands-on introduction to how gearing affects performance without having to modify electronics.
Key Features and Benefits
- 2-in-1 All Terrain and Street Configuration: Ships with both 90mm street wheels and MBS 100mm all-terrain wheels plus all necessary hardware to swap between them. One board that covers two completely different riding environments.
- Four Gear Ratio Options: Mixing 60T and 48T pulleys with 90mm and 100mm wheels creates four distinct performance profiles: maximum climbing torque, all-terrain all-around, street all-around, and maximum speed.
- 21 mph Top Speed: Achieved with the 48T pulley and 100mm wheels (gear ratio 4). The fastest configuration pushes performance well beyond typical electric longboard specifications.
- 20% Maximum Grade Climbing: Using the 60T pulley and 90mm wheels (gear ratio 1) delivers enough climbing torque for gradients that would defeat most electric boards.
- Dual 1800W Belt Drive Motors: Two motors deliver the power needed for genuine all-terrain performance. Dual motor configuration provides better traction on loose surfaces and more consistent power delivery.
- 180Wh Lithium Battery: Larger battery than the single-motor B10 models, supporting the higher power demands of dual motors and all-terrain use.
- 12-Mile Range: Based on 155lb rider riding conservatively on smooth flat terrain. Actual range varies with terrain, speed, and rider weight.
- Regenerative Braking: The motors act as generators during braking, recovering energy back into the battery and extending effective range.
- FOC Sine-Wave ESC: The smoothest, most efficient motor control technology available for electric skateboards.
- 40″ Bamboo/Maple Hybrid Deck: The longer deck provides stability at higher speeds while the bamboo/maple hybrid construction delivers the right combination of flex and stiffness for all-terrain riding.
- 2.4GHz Wireless Remote: Ergonomic remote with secure wireless connection for reliable control at all riding speeds.
- 275 lb Maximum Rider Weight: Accommodates a wide range of adult riders.
Understanding the Gear Ratio System
The B18-DX’s four gear ratio system is one of its most compelling features and one that rewards riders who take time to understand it. A smaller pulley (48T) turns the wheel faster relative to the motor, producing higher top speed. A larger pulley (60T) turns the wheel slower relative to the motor, producing more torque and better hill-climbing force at the cost of top speed. Combine this with wheel size and you get the full picture: larger wheels (100mm) have a larger circumference that covers more ground per revolution, adding speed. Smaller wheels (90mm) cover less ground per revolution, adding torque advantage.
Gear ratio 1 (60T pulley + 90mm wheels): Maximum torque, maximum hill-climbing. Use this for steep terrain where you need every bit of pushing power the motors can deliver. Gear ratio 2 (60T pulley + 100mm wheels): All-terrain all-around. Shipped as the default configuration, it balances speed and torque for mixed use. Gear ratio 3 (48T pulley + 90mm wheels): Street all-around. Good street performance with moderate hill capability. Gear ratio 4 (48T pulley + 100mm wheels): Maximum speed. Use this on smooth flat terrain when you want to push the board to its 21 mph limit.
Why Electric Skateboards Have Changed Urban Transport
The electric skateboard occupies a unique position in the personal electric vehicle landscape. Unlike an electric scooter or electric bike, it requires genuine skill to ride and rewards that skill with a riding experience that is genuinely exhilarating rather than merely convenient. The combination of a familiar skateboard form factor with electric propulsion creates a vehicle that is more compact and portable than any other electric personal transport option, while delivering speeds and range that make it practically useful for real commutes and not just recreational laps around the block.
For urban commuters who deal with the last-mile problem, where public transport gets you close but not quite there, an electric skateboard is often the ideal solution. It folds away (or in the case of skateboards, simply stows flat) under a desk or in a bag. It does not require locking up like a bike. It can cover a mile or two in minutes with zero effort beyond balancing. And unlike electric scooters or bikes, the riding experience itself is rewarding enough that riders actually look forward to their commute rather than simply tolerating it.

Electric Skateboard Safety
Electric skateboards travel at speeds that make falls significantly more dangerous than those on a traditional skateboard. Before every ride, suit up with the full protective gear that your riding speed demands. At minimum, wear a properly fitted, certified helmet on every single ride without exception. At the speeds that Atom B-series boards are capable of reaching, wrist guards, knee pads, and elbow pads are strongly recommended. Experienced riders who regularly push their boards to maximum speed should consider full-face helmets and padded shorts in addition to the standard kit.
Take time to learn your board before riding in traffic or challenging terrain. Spend your first several sessions in a quiet, open area building familiarity with how the board accelerates, how it brakes, and how it responds to your weight shifts at different speeds. Use the slow speed mode during this learning period, and only transition to fast mode once you have genuine confidence in your ability to control the board at lower speeds. The slow mode is not just for beginners – experienced riders use it in crowded environments and tight spaces where fine speed control matters more than maximum performance.
Regenerative braking on the Atom boards is a genuine safety feature as well as an efficiency one. The motor acts as a generator during braking, which creates a smooth, progressive braking force that is easier to control than friction braking. However, regenerative braking efficiency varies with battery charge level and speed, so always leave adequate stopping distance and avoid relying solely on regenerative braking in emergency stop situations.
Frequently Asked Questions
How long does it take to swap between all-terrain and street configurations?
With practice, the wheel and pulley swap takes approximately 10 to 20 minutes using a basic skate tool. The process becomes quicker with repetition and requires no electronics knowledge or special tools beyond what is included.
Which gear ratio should I start with?
The board ships assembled in gear ratio 2 (60T pulley, 100mm all-terrain wheels), which is the recommended all-around starting configuration. This gives you all-terrain capability with good speed and moderate torque before you experiment with the other combinations.
What is the range on a full charge?
Up to 12 miles based on a 155lb rider riding conservatively in slow mode on smooth flat terrain. Real-world range varies significantly with rider weight, terrain, speed, and riding style.
Is this board suitable for beginners?
The B18-DX is better suited for experienced electric skateboard riders due to its 21 mph capability and all-terrain use cases. Beginners should start on the slow speed mode and gain experience in controlled environments before attempting higher speeds or off-road terrain.

Choosing Your Atom B-Series Board
The three Atom B-series electric skateboards available through Electric Bikes Paradise each target a distinct riding profile. The B10 is the compact urban commuter optimised for pavement, weighing just 11 lbs with a kicktail deck that makes it easy to carry and manoeuvre in tight city spaces. The B10X takes the same core motor and battery platform and pairs it with 100mm all-terrain wheels and a longer deck for riders who want to go beyond smooth pavement onto gravel, grass, and packed dirt. The B18-DX is the flagship: dual 1800W motors, a 180Wh battery, and the unique 2-in-1 wheel system that lets you configure the board across four distinct gear ratios for either maximum climbing torque or maximum top speed.
For most urban commuters who ride exclusively on pavement, the B10 is the right choice. Its compact size, light weight, and lower price point make it the most practical daily commuter in the lineup. Riders who regularly encounter rough surfaces or want occasional off-road capability should choose the B10X. Riders who want maximum performance, genuine all-terrain versatility, and the ability to customise their board’s performance profile should choose the B18-DX.

About Atom Electric: The B-Series Difference
Atom Longboards has been building premium electric skateboards with a focus on performance, safety, and honest engineering since the early days of the electric skateboard market. Their B-series electric boards are built around a simple but critical philosophy: the most important component in an electric skateboard is the battery, and there is no substitute for quality lithium cells from proven manufacturers like Samsung, LG, and Panasonic.
Every battery that goes into an Atom B-series board is tested at peak charge and discharge rates before installation, ensuring that no underperforming cell makes it into a finished product. This commitment to battery quality directly affects rider safety, board performance, and long-term ownership experience. A quality battery performs consistently across its full charge cycle, degrades predictably over years of use, and behaves safely in the event of impact or overcharge, none of which can be guaranteed with lower-cost alternatives.
The FOC (Field Oriented Control) sine-wave ESC technology used across the B-series is another area where Atom invests in quality that less expensive boards forego. FOC sine-wave controllers deliver power to the motor in a mathematically optimised waveform that minimises heat, maximises efficiency, and produces the smooth, progressive acceleration and braking that experienced riders value. The alternative, BLDC square-wave technology used in most budget boards, produces a noticeably rougher power delivery that is less comfortable, less efficient, and harder on the motor over time.
