Chassis & Construction
Steel Frame. Unyielding Strength.
Engineered on a Robust Steel Foundation
The Romeo's frame is constructed from high-tensile steel, selected for its superior fatigue resistance and vibration-damping characteristics. While many manufacturers have migrated to aluminum for weight savings, steel offers distinct advantages for an electric mountain bike of this caliber: it absorbs trail chatter more effectively, resists stress cracking under repeated heavy loads, and provides a planted, stable feel at speed.
Weighing 61.7 lbs (28 KG), the Romeo strikes a deliberate balance between structural integrity and manageable heft. The weight contributes to a grounded, confidence-inspiring ride quality—especially appreciated when descending rough terrain or carrying cargo. The frame geometry has been optimized for a comfortable, upright riding position that reduces fatigue on longer journeys while maintaining the agility needed for technical trail navigation.
Every weld point undergoes rigorous inspection, and the frame is treated with a corrosion-resistant coating to withstand the elements. The integrated internal cable routing keeps lines clean and protected from snags, while reinforced dropouts ensure the dual motor torque is transmitted efficiently without flex or compromise.

Traction & Control
20-Inch Fat Tires — Go Anywhere
Wide Contact Patch, Unmatched Stability
The Romeo rolls on 20-inch fat tires that measure approximately 4.0 inches in width, providing an expansive contact patch that grips tenaciously across sand, snow, mud, gravel, and hardpack. This oversized footprint distributes the bike's weight over a larger surface area, reducing ground pressure and preventing the tires from sinking into soft terrain—a critical advantage when venturing off the beaten path.
Fat tires also act as a natural suspension system. When run at lower air pressures, they absorb small bumps, roots, and rocks, smoothing out the ride without the added complexity and weight of a full suspension linkage. The 20-inch diameter strikes an ideal balance between rollover capability and nimble handling, making the Romeo equally adept at weaving through tight urban spaces and carving along winding singletrack.
The aggressive tread pattern is directional, designed to channel mud and debris away from the contact surface while maintaining consistent grip during both acceleration and braking. Whether you are commuting through potholed city streets or exploring remote fire roads, these tires deliver the confidence to push further.

Drivetrain
7-Speed Precision Shifting
Adaptive Gearing for Every Landscape
The Romeo is equipped with a 7-speed Shimano-compatible gear system that provides a versatile range of ratios suitable for both high-speed pavement riding and low-speed technical climbing. The gear indexing is crisp and reliable, with each shift engaging positively to minimize chain slippage and drivetrain wear.
Having seven distinct gears allows riders to fine-tune their cadence to match the terrain. On steep ascents, drop into the lower gears to let the dual motors work efficiently without over-spinning. On flat stretches or descents, shift up to maintain momentum and maximize the electric assist's contribution. The gear system works in harmony with the electric powertrain, giving you complete command over how much human effort you want to contribute.
The derailleur is protected by a robust guard that shields it from rock strikes and trail debris, ensuring consistent performance even in harsh riding environments. Combined with the twist throttle, the 7-speed system offers a riding experience that adapts fluidly to changing conditions—from stop-and-go city traffic to open country roads.

Safety Systems
Hydraulic Disc Brakes — Stop on Command
Progressive Braking, All-Weather Confidence
Stopping power is non-negotiable on a bike capable of the speeds the Romeo can achieve. That is why it is outfitted with a hydraulic disc brake system on both the front and rear wheels. Unlike mechanical cable-actuated brakes, hydraulic systems use fluid pressure to transfer force from the lever to the caliper, resulting in smoother modulation, greater stopping force, and reduced hand fatigue on long descents.
The disc rotors are sized appropriately for the bike's weight and speed potential, providing consistent, fade-resistant performance even during prolonged braking on steep grades. The hydraulic system is sealed, meaning it requires minimal maintenance and is largely unaffected by water, mud, or dust ingress—critical for a bike designed to venture off-road.
In emergency stopping scenarios, the brakes deliver immediate, controlled deceleration without the grabby, unpredictable bite that can plague lesser systems. For riders who value safety as much as performance, the Romeo's braking setup offers genuine peace of mind.

Cockpit & Intelligence
Smart LCD Display & Twist Throttle
Information at a Glance, Control at Your Fingertips
Mounted centrally on the handlebar, the backlit LCD display provides real-time feedback on essential ride metrics: current speed, battery charge level, pedal-assist mode, trip distance, and odometer reading. The screen is designed to be legible in direct sunlight and automatically adjusts brightness for nighttime visibility, ensuring you are never left guessing about your ride status.
The twist throttle is ergonomically positioned for natural wrist motion, allowing you to modulate speed with precision. Unlike thumb throttles that can cause fatigue on longer rides, the twist design distributes effort across the entire hand, making extended journeys more comfortable. A gentle twist delivers a subtle boost; a full twist unleashes the full 1000W of combined motor output.
Between the LCD's clear data presentation and the intuitive throttle response, the Romeo keeps you connected to the machine without overwhelming you with unnecessary complexity. It is a purposeful, rider-focused interface that enhances the experience rather than distracting from it.
