Like A Fine Black Custom-Tailored Suit …

… the Boulevard Luxe enters the city stage in style. The practically maintenance-free combination of gear hub and belt drive make sure this is a lasting impression. You can't expect anything less than reluctant functionality from the ergonomically bent handlebar to the stationary rear light and all the remaining complete specs. That's it!

  • Comfortable city and touring bike w/ maintenance-friendly belt drive and freewheel
  • Responsive suspension fork with aluminum steerer tube
  • Stiff and comfortable due to tapered seat tube
  • High-quality Shimano Nexus Premium hub (8-speed)
  • Busch + Müller LED light (front and rear)

Technology

Belt Drive

A belt drive, as the name suggests, uses a drive belt instead of a chain to transfer power from the cranks to the rear wheel. Since the belt cannot be split like a chain the special STEVENS frame utilizes a splittable seat stay, but the advantages are convincing: lower weight, silent operation, almost endless longevity without any maintenance.

Adjustable Dropouts

High quality STEVENS frames equipped with a gear hub or Pinion 18-gear box come with adjustable dropouts. These make correct tensioning of the chain or drive belt very easy. Adjustment via headless set screw and Allen key allows very precise alignement. Two fastening bolts on each side provide tight grip. On bikes with derailleur shifting the chain is tensioned by the derailleur.

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.

Reifenfreiheit bis 47mm

Wer häufiger auf Strecken mit weniger glattem Untergrund unterwegs ist, kann bis zu 47 mm breite Reifen montieren – und dann von mehr Fahrkomfort und Pannenschutz profitieren, die deren größeres Luftvolumen mit sich bringt, weil nunmehr mit geringerem Reifenluftdruck gefahren werden kann. Die Rahmen und Gabeln dieser Bikes sind jedenfalls schon darauf vorbereitet.
