The BH iRS1 Carbon 1.6 2026 bike we’re introducing at Escapa redefines electric road bikes: lightweight, quiet, powerful, and with a range that will take you farther than ever before. Its BHZ motor delivers 65 Nm of natural and immediate assistance, while its battery—with a capacity of up to 810 Wh—ensures endless rides. Its carbon frame, featuring HCIM technology, guarantees stiffness, style, and aerodynamic efficiency on every stretch of road. Perfect for cyclists who want to enjoy the road without sacrificing performance.
PERFORMANCE CARBON LAYUP
The sensations we sought with the new iRS1 are power, range, and lightness, combined with a design that guarantees maximum performance and optimal ergonomics for covering long distances.
The iRS1 is built using the same technology as BH’s high-end frames, employing the Hollow Core Internal Molding technique. This high-pressure internal hollowing process ensures the highest levels of material density, eliminates inconsistent pressures, and prevents the formation of bubbles and imperfections in the carbon.
In addition, we use Performance Carbon Layup, a type of carbon that maximizes the balance between lightness and stiffness, resulting in an exceptional bike in every respect.
BHZ MOTOR BY SEG AUTOMOTIVE
With a maximum torque of 65 Nm, a weight of 2.1 kg, and a peak power output of 500 W, this motor is designed to deliver exceptional performance.
Its major innovations lie in the assistance management system, providing immediate motor response during both acceleration and braking, progressive and natural power delivery, and 100% assistance at all times. Additionally, it features a smoother cut-off of assistance when reaching the speed limit and is virtually silent.
Equipped with three advanced sensors—torque, speed, and cadence—it takes more than 1,000 readings per second to ensure seamless interaction and immediate response.
Instant Motor Start-up
The sensors and powerful microprocessor guarantee an immediate motor response as soon as you start pedaling.
Progressive and natural assistance
Its intelligent assistance prioritizes sensor signals based on the rider’s situation. You’ll feel the motor’s power when applying torque, but on flat terrain or when you don’t need as much power, the torque will adjust automatically.
Hill Start Assist
The BHZ by SEG motor includes a preload feature for starting on inclines. When you come to a stop on a hill, the motor will activate instantly as you start moving again, without needing to pedal.
Progressive Assistance Cutoff at 25 km/h
The BHZ by SEG motor smoothly reduces assistance upon reaching the speed threshold, avoiding abrupt cuts and providing a more natural pedaling sensation.
BHZ BATTERY
All models come equipped with a 630Wh battery, located in the down tube and weighing 2.6 kg. This battery, composed of 5.8Ah 21700 cells, offers maximum energy density and allows for more energy to be stored in a compact space, resulting in a low center of gravity for a natural riding experience.
In addition, the external XPro battery provides an additional 180Wh, increasing the range to 195 km. (Optional)
CORE DISPLAY + iButton SYSTEM
Display integrated into the stem
Colored LED indicators
Switch modes without letting go of the handlebars
Full compatibility with the BH iConnect app
