# Intentionally Noisy Motorbike Concepts The rStream Motorcycle Uses Sound to Protect Its Rider By Michael Hines | Published 2011-08-24 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/rstream-motorcycle References: [ecofriend](http://www.ecofriend.com/entry/rstream-concept-motorcycle-fusion-emission-ride-unique-safety-features/) & [clementlagneau](http://www.clementlagneau.com/?page=portfolio&gal=rstream) Clément Lagneau's rStream Motorcycle is an [eco-friendly bike](https://www.trendhunter.com/trends/ethunder) designed to protect its rider with sound. The rStream creates different sounds depending on the speed of the bike. Riders driving the bike through the city at a low and safe speed will hear a "natural sound." As the rider increases his speed, so does the rStream Motorcycle increase its sound. At high speeds, the bike emits a [high-pitched whine](https://www.trendhunter.com/trends/dust-hightail-electric-dirt-bike). The purpose of this whine is to make motorists aware of the motorcycle besides them. The rStream creates its sound using wind-powered infrabass (air rushing in creates the sounds). Besides the ability to make noise, the bike also has a storage compartment where its gas tank would be. The wheels on this bike are both spoke-less and are partially covered. According to Lagneau, the covering of the wheels improves traction and stability.
