Your loyal Companion for City and Countryside.

You can't go into the city and on tour with fewer worries than on a Boulevard: At the front a suspension fork that even irons out the occasional pothole. Strong V-brakes and the 8-gear twist grip at the handlebar provide you with the utmost control at any desired speed. And the gearhub at the back will last as long as the sturdy carrier.

  • Stiff and comfortable city and touring bike
  • Responsive suspension fork with aluminum steerer tube
  • High-quality Shimano Nexus Premium hub (8-speed)
  • Busch + Müller LED light (front and rear)
  • Puncture-resistant, smooth running Schwalbe tires

Technology

Tapered Seat Tube

The seat tube tapers from top to bottom. At the top it fits a slim 27.2mm seatpost that offers some flex and therefore increases comfort especially when riding over rough ground. At the bottom the large diameter nicley flows into the bottom bracket shell and downtube to provide great stiffness and drivetrain efficiency.

Hydroforming

Using water or oil pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers to perfectly withstand any load without any weight penalty. Riders of allround bikes and pedelecs will benefit from a better stability caused by hydroforming even when they are touring with heavy luggage.

Triple Butted, Double Butted

Meaning a frame tube has three or two different wall thicknesses along its length. Triple butted (TB) is the usual technology with STEVENS high-quality frames.
Tubes with different wall thicknesses are optimally adjusted to certain ways of manufacturing or to withstand specific loads. Where the highest loads occur or where tubes are welded, walls are the thickest. Butted tubes allow frame weight to be lower by several hundred grams.
