B-9 NH Urban Stealth

"The bicycle would be Black, almost radar absorbent. Any eye that caught it would be captured in its dark gravity. With flat paneling it would look like a veiled threat."

A handmade Urban Stealth singlespeed bicycle with styling inspired by the famous F-117 Nighthawk aircraft. The B-9 NH Urban Stealth represents the evolution of the BME X-9 concept bicycle and features a carbon fiber frame and fork, one piece carbon stem-handlebar, BME Design's unique carbon S72 Saddle system, and CNC machined alloy cranks custom designed for the B-9 NH.



  • built to withstand the abuse of the harsh reality of the urban environment
  • frames and components tested in EU labs


  • minimal maintenance, zero hassle riding
  • single speed carbon belt drive and mechanical discs combine to mean you ride, not fiddle
  • equipped with S72 saddle system for instant and precise single bolt adjustment
  • carbon belt drive requires no greasing, is lighter and quieter than a chain and lasts longer


  • matt black color finish and stealth angles are discrete and head turning, at the same time
