Proudly Presents:
| It's in the news: the US National Highway Traffic Safety Administration (NHTSA) has mandated that quiet hybrid and electric cars produce a distinctive sound, to alert visually-impaired and inattentive pedestrians. But, cyclists, take note! An obscure provision of the recent US transportation bill (MAP 21) also required that the Federal Highway Administration's Turner-Fairbank Highway Research Center develop a bicycle audibility standard. Testing is underway as of this writing. ShelBroCo could not let the challenge to produce a practical, compact, lightweight, economical sounder system pass by. |
