Assault Fitness: The CrossFit/HIIT Cardio Specialists - The Range

AirBikes: From Entry-Level to Elite Performance

The Assault AirBike collection spans three performance tiers, each engineered for progressively demanding applications. Entry-level models deliver proven fan-based resistance with heavy-duty steel frames and comprehensive console tracking, ideal for home HIIT sessions, warm-ups, and rehabilitation work. Mid-tier options introduce whisper-quiet belt-driven systems with advanced connectivity, perfect for shared training spaces. Elite commercial models feature reinforced construction, forward and reverse pedalling capability, removable windscreens, and extended warranties designed to withstand relentless gym traffic.

Air resistance automatically scales with effort across all models—the harder you push, pull, or pedal, the greater the resistance. This infinite scalability means beginners and elite athletes train effectively on the same equipment, with no adjustments required.

Manual Curved Runners: Self-Powered Performance

Assault's non-motorised curved treadmills redefine running training through athlete-powered design. The curved deck promotes natural biomechanics whilst burning up to 30% more calories than traditional motorised treadmills, with zero electrical consumption.

Pro-level runners offer lightweight construction with compact footprints, making them amongst the most space-efficient curved treadmills available. Slat belt running surfaces are rated for extraordinary mileage with no tension adjustments or deck replacements required. Elite commercial models feature overbuilt frames with solid steel and heavy-duty oval tubing, delivering up to 94% reduction in impact stress for longer, harder training sessions without injury risk. Built-in transport wheels, app connectivity, and customisable programming ensure user-friendly operation despite robust construction.

With no maximum speed setting, athletes control intensity entirely through their own effort—perfect for interval training, sprint work, and progressive conditioning.

Rowing: Fan-Based Total-Body Training

Assault's rowing machines combine fan-based resistance with dual-stage drive systems (chain and belt) for smooth, familiar rowing experiences that won't be overpowered by high-intensity efforts. Sweat-proof ergonomic seats, solid steel foot pedals, and powder-coated steel and aluminium construction ensure commercial durability, whilst compact, foldable designs allow upright storage.

Expansive consoles offer Bluetooth connectivity and multiple pre-programmed workouts. Rowing targets back, legs, triceps, pecs, deltoids, obliques, glutes, and abs simultaneously—ideal for HIIT, cardio, or endurance training.

Benefits of Assault Fitness

  • Athlete-Powered, Infinitely Scalable – Every Assault machine uses air or self-generated resistance, meaning intensity scales automatically with effort. Beginners and elite athletes train side-by-side on the same equipment—no adjustments, no motors, no limits.
  • Built for High-Intensity Interval Training – Purpose-designed for HIIT protocols, Assault equipment handles rapid speed changes, explosive efforts, and relentless commercial use. Onboard programming, competition modes, and interval timers keep workouts structured and challenging.
  • Total-Body Engagement – AirBikes integrate upper and lower body movement, whilst runners promote natural biomechanics and rowers recruit multiple muscle groups simultaneously. Every session delivers comprehensive conditioning.
  • Commercial Durability, Home-Friendly Design – Heavy-duty steel frames, sealed-cartridge bearings, corrosion-resistant hardware, and extended warranties ensure longevity. Compact footprints, transport wheels, and quiet operation suit home environments without compromising performance.
  • Low Maintenance, High Reliability – Encased drivetrains, built-in linkage kits, and slat belt surfaces minimise upkeep. No belt tension adjustments, no deck replacements, no motor servicing—just consistent, reliable training.
  • Connected Training – Bluetooth and ANT+ connectivity across advanced models sync with the Assault Fitness app and third-party platforms, enabling workout tracking, performance analysis, and programme customisation.
  • Eco-Conscious Performance – Non-motorised runners and self-powered bikes and rowers consume zero electricity, reducing environmental impact whilst delivering superior calorie burn and conditioning results.

Assault Fitness Buying Tips

Match the Model to Your Environment

  • Home gyms: Entry and mid-tier AirBikes (particularly belt-driven models for quieter operation) and compact rowers offer excellent value with space-efficient storage.
  • CrossFit boxes and commercial gyms: Elite-tier AirBikes and commercial-grade runners are engineered for high-traffic, high-intensity use with extended warranties and reinforced construction.
  • Rehabilitation and versatile training: AirBikes' ability to isolate or integrate upper and lower body movement makes them ideal for post-injury work and progressive conditioning.

Consider Your Training Focus

  • HIIT and interval work: All Assault machines excel here, but elite AirBikes and curved runners offer the most aggressive programming and competition modes.
  • Endurance and steady-state cardio: Rowers and commercial-grade runners provide smooth, sustainable resistance for longer sessions.
  • Total-body conditioning: AirBikes and rowers engage multiple muscle groups simultaneously; runners focus on lower-body biomechanics and cardiovascular capacity.

Evaluate Noise Sensitivity

If noise is a concern (flats, home offices, early-morning training), belt-driven AirBike systems are significantly quieter than chain-driven models whilst maintaining full performance.

Factor in Connectivity and Programming

If app integration, workout tracking, and advanced programming matter, prioritise models with Bluetooth/ANT+ capability and onboard HIIT protocols.

Assess Space and Portability

Curved runners are amongst the lightest in their category; rowers fold for upright storage. AirBikes have similar footprints across models, but elite versions' larger frames offer greater stability during maximal efforts.

Warranty as a Durability Indicator

Longer warranties signal confidence in construction. Look for extended frame warranties (up to 10 years on elite models) and comprehensive parts coverage when selecting equipment for long-term investment.

Assault Fitness Frequently Asked Questions

What makes Assault Fitness equipment different from standard cardio machines?

Assault machines are athlete-powered and use air or self-generated resistance, meaning there's no maximum speed or resistance cap. Intensity scales infinitely with your effort, making them ideal for HIIT, CrossFit, and functional training. They're also non-motorised (runners) or low-maintenance (bikes, rowers), with commercial-grade construction suited to both home and gym environments.

Which Assault AirBike tier should I choose?

  • Entry-level: Best for home users, warm-ups, rehabilitation, and those seeking proven fan-bike performance with comprehensive tracking.
  • Mid-tier: Ideal for home gyms prioritising quiet operation, connectivity (Bluetooth/ANT+), and low maintenance with belt-driven smoothness.
  • Elite: Built for commercial gyms and serious athletes demanding maximum durability, advanced programming, and features like forward/reverse pedalling with extended warranties.

Are Assault Runners suitable for beginners?

Yes. The curved design and self-powered resistance allow users to control speed entirely through their own effort—there's no motor to keep pace with. Beginners can walk or jog at comfortable speeds, whilst advanced athletes can sprint without limitation. The natural running motion also promotes proper form and reduces impact stress significantly.

Do I need electricity to use Assault equipment?

No. Assault Runners are entirely non-motorised, and AirBikes and rowers are self-powered (consoles run on internal power generated during use or batteries). This makes them eco-friendly, portable, and usable anywhere without electrical outlets.

What kind of maintenance do Assault machines require?

Minimal. Sealed-cartridge bearings, encased drivetrains, and slat belt surfaces are designed for low upkeep. Runner belts are rated for exceptional mileage with no tension adjustments or deck replacements needed. Regular cleaning and occasional lubrication of moving parts keep machines performing optimally.

Are Assault machines suitable for commercial gyms?

Absolutely. Elite-tier AirBikes and commercial-grade runners are specifically engineered for commercial environments, with reinforced frames, extended warranties, and components rated for high-traffic, high-intensity use.

How do Assault Runners compare to motorised treadmills for calorie burn?

Assault Runners burn up to 30% more calories than traditional motorised treadmills due to the self-powered, curved design that engages more muscle groups and requires greater effort to maintain speed.

Can I use Assault AirBikes for rehabilitation?

Yes. AirBikes are particularly well-suited for post-injury rehabilitation, as they allow isolation or integration of upper and lower body movement at a personalised, controlled pace. Air resistance adjusts automatically to effort, making it safe and effective for progressive recovery protocols.

What's the difference between chain-driven and belt-driven AirBikes?

Chain-driven models offer proven durability and direct power transfer, whilst belt-driven systems deliver significantly quieter operation—ideal for home environments and shared training spaces. Both systems provide the same infinite air resistance scaling; the choice depends on noise sensitivity and environment.
