🔩 Build Quality & Adjustability
Weighing 125 pounds, the AssaultBike ProX is constructed with corrosion-resistant steel. Unlike the bulkier Rogue Echo Bike, it fits better in smaller spaces while still offering commercial-grade durability. The seat and handlebars are adjustable, and it includes foot pegs for upper-body-only workouts.
📦 Setup & Assembly
Assembly is simple and beginner-friendly. The bike ships 75% pre-assembled and includes all required tools. Setup takes roughly 35–45 minutes.
📊 Monitor & App Integration
The LCD monitor offers seven built-in programs and connects to the Assault Fitness App via Bluetooth. While not as immersive as Peloton, it’s functional and tracks key metrics like watts, RPM, and calories.
Pro Tip: If you’re training for performance, tracking watts and RPM is invaluable — a feature the Rogue Echo Bike doesn’t offer.
🔌 Power & Noise
No electrical outlet is required; the monitor runs on AA batteries. The belt-drive reduces noise compared to chain bikes like the Schwinn Airdyne.
