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

Safety and testing

The pre-production series of B-9 NH was made for testing. All the parts produced by BME Design - the frame, fork, handlebars with the stem, saddle assembly and crankset passed the tests and fulfill the safety and quality requirements according to the EN 14764:2006 standard. The testings were provided by accredited Engineering Test Institutes in Czech Republic.


The B-9 NH Urban Stealth bicycle was presented at the following exhibitions:

  • 'Bike to the Future', Museum of Design Atlanta, USA, April-July 2021
  • 'BIKES - the reinvention of the bicycle', Grassi Museum for Applied Art Leipzig, Germany, June-October 2017
  • 'Bike l Design l City' Exhibition, Gewerbemuseum Winterthur, Switzerland, January-July 2017
  • Eurobike Show (displayed in the Gates Carbon Drive booth), Friedrichshafen, Germany, August 2015
  • Like Bike Monte Carlo, Monaco, April 2015
  • North American Handmade Bicycle Show, Charlotte, NC, USA, March 2014


The project of the B-9 NH Urban Stealth bicycle was recently stopped due to the fact that I didn't find a partner for financing and sales. However, I did manufacture three of these bicycles (further production no longer possible). Two complete bicycles were used for testing, exhibitions, presentations and test riding. The third bicycle remains unpainted and unassembled.

So, the third bicycle, practically speaking, is the only one in the world available for sale. The unique nature of the bicycle makes it suitable as an investment, since no one else will be able to buy another ever again.

The bicycle is suitable for someone who wants to have unique items, items which differentiate themselves from others. Choice of bicycle color, color layout, or maybe advertising logo for a company will be included in the price.

In case of your interest, please contact me with your price offer. I should mention that due to my investment in this project I do have a reserve price in mind for the sale. Thank you for your interest.
