The e-bike revolution has taken to the off-road, with off-road capable bikes being a massive hit among adventure seekers. From woodsy trails to desert trails, these rugged machines provide pedal assist with rugged construction to tackle challenging terrain. This guide takes a deep dive into two different off-road e-bike approaches - the Attack 10 and the SUPER73-S2 SE - breaking down their respective features to help you find your perfect trail companion.

Quick Comparison: At a Glance

Frame Design and Rider Stance - Revolutionary Construction vs. Traditional Approach

🏆 Winner: Attack 10 - Innovative Magnesium Alloy Frame

Attack 10 stands out through its innovative water-injection molding process that creates a strong magnesium alloy frame. The assembly method eliminates welding points entirely, offering greater structural integrity without sacrificing looks. The single-piece casting process creates a beautiful profile as strong as it's exclusive.

By contrast, the SUPER73-S2 SE utilizes a more conventional aluminum frame. Although marginally lighter (a contributing factor in its 13-pound weight differential), it uses conventional manufacturing techniques. The aluminum build provides acceptable durability, although not the same integrated feel and sophisticated manufacturing method as the Attack 10.

Geometry differences across these bikes play a significant role in riding position. The Attack 10 puts riders into a more aggressive, front-leaning position that assists weight distribution when climbing down steep gradients. The SUPER73-S2 SE offers a more upright stance comfortable for many riders over shorter distances, at the cost of technical handling in extremely challenging terrain.

Both bicycles accommodate various heights of riders, albeit they have individualized shapes to meet varying aesthetics sensibilities – Attack 10 carrying futuristic design inspiration and the SUPER73-S2 SE with more classic motorbike-inspired aesthetics.

Motor Power and Performance Output - Breaking Down the Numbers: Not All 750W Motors Are Created Equal

🏆 Winner: Attack 10 - Higher Torque & Faster Top Speed

Don't let the identical 750W ratings fool you – these motors deliver significantly different riding experiences. The Attack 10's Bafang brushless geared hub motor generates an impressive 89Nm of torque, translating to explosive acceleration and superior hill-climbing ability. This higher torque rating makes a substantial difference when powering through loose surfaces or conquering steep inclines.

The performance gap becomes even more apparent when examining top speeds. The Attack 10 reaches exhilarating 30 MPH speeds (in off-road mode), while the SUPER73-S2 SE tops out at just 20 MPH. This 10 MPH difference dramatically changes the riding experience, particularly for thrill-seekers looking to cover ground quickly on open trails. For riders wanting more excitement and capability from their e-bike, the Attack 10 clearly pulls ahead.

Both bikes employ pedal assist systems, though the Attack 10 offers five PAS settings compared to the SUPER73-S2 SE's four. The throttle implementation differs too – a motorcycle-style twist throttle on the Attack 10 versus a thumb throttle on the SUPER73-S2 SE – with many riders preferring the intuitive control of the twist throttle for off-road use.

Battery Capacity and Real-World Range - The Truth About Range: Attack 10 Takes the Lead

🏆 Winner: Attack 10 - 33% More Battery Capacity

Battery capacity represents one of the most significant technical differences between these e-bikes. The Attack 10 packs a substantially larger 960Wh battery compared to the SUPER73-S2 SE's 720Wh power source. This 33% capacity advantage directly translates to extended range capabilities.

The real-world impact is clear in the range specifications:

• Attack 10: 40-68 miles per charge
• SUPER73-S2 SE: 35-45 miles per charge

Several factors influence actual range performance:

• Rider weight Terrain difficulty
• Pedal assist level selected
• Weather conditions
• Tire pressure
• Battery age

The larger battery in the Attack 10 uses Samsung cells known for reliability and consistent performance over time. Both bikes require 5-6 hours for a full charge, reasonable given their respective capacities. While both batteries are removable, the additional power of the Attack 10 comes with a minimal weight penalty – its battery weighs approximately half a pound more than the SUPER73-S2 SE's. For adventure riders looking to explore further from civilization, the Attack 10's superior range provides invaluable peace of mind.

Suspension Systems and Ride Comfort - Full Suspension vs. Front Only: Attack 10's Comfort Advantage

🏆 Winner: Attack 10 - Full Suspension System

The suspension approach represents perhaps the most fundamental philosophical difference between these off-road contenders. The Attack 10 commits fully to off-road performance with a comprehensive full suspension setup, featuring a dual crown air fork with generous 160mm travel up front and rear suspension to absorb impacts from both ends.

The SUPER73-S2 SE takes a different approach, equipping a dual crown air fork with 140mm travel up front but maintaining a rigid rear end. This design choice reduces complexity and weight but sacrifices significant comfort and traction on particularly rough terrain.

The Attack 10's full suspension design makes it exceptionally capable when tackling:

• Rocky, technical descents
• Root-covered forest trails
• High-speed bumpy sections
• Small drops and jumps

The SUPER73-S2 SE's front-only suspension performs adequately in different scenarios:

• Smoother gravel roads
• Urban environments with occasional rough patches
• Riders who prioritize pedaling efficiency

For riders primarily tackling genuinely rough terrain, the Attack 10's full suspension setup offers undeniable advantages in comfort and control. The rear suspension component is not merely a luxury but a functional necessity for maintaining traction and rider comfort when pushing the limits off-road. The Attack 10's more generous 160mm front travel (versus 140mm on the SUPER73-S2 SE) further enhances its capability on technical descents.

Tire Design and Terrain Grip - Balanced Tires vs. Specialized Setup

🏆 Winner: Tie - Different Approaches for Different Needs

The Attack 10 features even 20×4" fat tires that provide excellent flotation on soft terrain like sand and snow without compromising the bike's balance. The symmetrical tire design also facilitates maintenance since front and rear tires are interchangeable, thus making spare tire management a much simpler affair for adventure riders.

The SUPER73-S2 SE employs a more targeted approach with asymmetrical front and rear tire widths – 4.5" front and 5" rear MAXXIS SuperSucker tires. This asymmetrical setup attempts to merge steering responsiveness up front and maximum grip in the rear, but it complicates maintenance by requiring unequal spare tubes and tires.

Fat tires on both bikes provide key benefits to off-road handling:

1. Increased stability on rough surfaces

2. Augmented shock absorption by the big-volume air cushion

3. Transitory enhanced traction on slippery surface

4. Declined risk of puncturing

5.Simplified reduced tire pressure as an alternative based on conditions

While the SUPER73-S2 SE's narrow rear tire might provide marginally better flotation in extremely soft going like heavy sand, the Attack 10's well-balanced tire sizes provide more stable handling for a greater range of terrain types. Adding its full suspension setup to the mix, the Attack 10 provides superior overall traction under adverse conditions.

Braking Systems and Safety - Stopping Power When You Need It Most

🏆 Winner: SUPER73-S2 SE - Larger Brake Rotors

Both bikes equip hydraulic disc brakes – the gold standard for off-road riding where reliable stopping power is non-negotiable. The Attack 10 employs 160mm rotors front and rear, while the SUPER73-S2 SE uses larger 180mm Tektro HD-E350 rotors.

The larger rotor diameter on the SUPER73-S2 SE provides several advantages:

• Greater surface area for heat dissipation
• Enhanced stopping power, particularly on long descents
• Better modulation for precise braking control

However, the Attack 10's braking system is more than adequate for its intended use, with the hydraulic actuation providing excellent modulation and requiring less hand effort than mechanical alternatives. The Attack 10's full suspension system actually improves braking performance by maintaining better tire contact with the ground during heavy braking on rough terrain – a critical advantage the SUPER73-S2 SE's rigid rear end cannot match.

For most riders, the Attack 10's braking performance hits the perfect balance of power and control, especially when considering its overall superior off-road capabilities and substantially lower price point.

Intended Use and Versatility - Finding Your Perfect Riding Match

🏆 Winner: Attack 10 - Greater Versatility

Understanding each bike's best features helps to match them with your riding. The Attack 10's full suspension, higher top speed, and larger battery make it a better dedicated and more able off-road adventure bike. The extra power, suspension travel, and range position it well for riders who attack really challenging terrain on a regular basis and those looking to ride farther from civilization.

The SUPER73-S2 SE finds a different balance, with strong front suspension and styling that enters the urban environment more gently but easily accommodating light forays onto trails. Its lower weight provides improved handling in tight spaces, but the reduced top speed and smaller suspension make it less desirable to riders seeking utmost off-road performance.

They both have utilitarian features like integrated LED lighting systems (front and back) and kickstands. Neither has a rear rack as a standard feature, though aftermarket options exist for both. The weightier payload capacity goes to the Attack 10 (350 lbs vs. 325 lbs), so it is better suited for bigger riders or carrying more gear on trips.

The drivetrain options further highlight their differing strategies – the Attack 10's 7-speed Shimano drive train system provides options for differing terrain and pedaling styles, whereas the SUPER73-S2 SE's single speed configuration takes simplicity over flexibility. For riders confronting varied terrain, the Attack 10's variable gears provide a significant practical advantage.
