The Ultimate Performance Machine: A Rider's Perspective
What stands out first is the premium construction. The full carbon shell, carbon subframe, and carbon swing arm make it incredibly light at just 55 pounds (25 kg). This lightweight construction combines with excellent aerodynamics to create a truly efficient riding experience.
The versatility of this vehicle is remarkable. I’ve used it for everything from long-distance touring to daily commuting. The generous storage options along the rear wheel well, under the seat, and the optional front storage bins make it practical for running errands or longer trips. The foam pad system for adjusting the seat back angle is stable and comfortable.
Performance-wise, it corners excellently, especially with the squared suspension setup. The handling in wind conditions is impressive, and the 50mm boom provides great airflow for comfort during rides. I particularly appreciate the multiple gearing options (2×11 or 1×12 speed systems) and the ability to choose between tiller and tank steering.
The customization options are extensive. From various paint choices to electrical additions like blinkers, horn, brake lights, and different headlight options, you can really make it your own. The ability to adjust between sport and comfort suspension means you can configure it for virtually any riding scenario.
Frequently asked questions
“Oops, what was that? An electric car? Was that solar? Does this have a motor or why is it so fast?” We hear these questions often when people first encounter the Bülk MK1. With over 100 years of velomobile history behind it, and groundbreaking modern engineering within it, the Bülk MK1 tends to turn heads. Here are answers to the questions we most frequently receive about this revolutionary vehicle.
What makes the Bülk MK1 so fast?
The exceptional speed comes from advanced aerodynamic design, verified through wind tunnel testing. The semi-laminar design with a flattened bow minimizes air resistance, while the stiff carbon construction and optimized power transmission ensure your effort translates directly to speed.
How does weather protection work?
The Bülk MK1 offers comprehensive weather protection with optional hoods featuring overlapping water edges and effective drainage systems. You can choose between race hoods or everyday hoods with motorcycle visors and windscreen wipers. The ventilation system ensures comfort in all conditions.
Can different people share one Bülk MK1?
Absolutely! One of the Bülk MK1's unique features is its tool-free adjustment system. It can accommodate riders from 150-200cm in height, with quick adjustments to the seat, headrest, and hood configuration. This makes it perfect for families or sharing arrangements.
Can I use the Bülk MK1 in the city?
Yes! The Bülk MK1 is highly maneuverable in urban environments despite its racing pedigree. Its compact design (257cm length, 70cm width) allows for easy navigation through traffic, and you can use both road and suitable cycle paths. The high seating position and excellent visibility make it perfect for city commuting.
What exactly is a velomobile?
A velomobile is a human-powered vehicle with an aerodynamic body. The Bülk MK1 combines the efficiency of a bicycle with weather protection and comfort. The rider sits in a comfortable reclined position, protected from the elements while achieving remarkable speeds with less effort than a conventional bicycle.
