The Redbull Soundbike & Cooler Bike / Branded Promotion Soundbike / 2012

For the red-bull branded sound and cooler bike duo we went to the full length of customization, starting with two all naked Bullitt frames, custom powder coated in matt black to match the red bull vehicle fleet. The bikes were equipped with high quality components only, extra fat tires were mounted for planned beach-side actions. The soundbike was equipped with our latest development "The Voice" providing high quality sound and performance paired with power galore. For this assignment "The Voice" was extended by an integrated storage compartment, all painted in matt black to match the frame. Silver aluminium-plotted logos were aplied and, for extra advertising space, a billboard was fitted to the Bullitt frame. A second Bullitt bike equipped with a custom fitted mobile fridge was designed likewise to complete the impressive couple. Among other events and promotion activites the bikes were a central element to the 2012 RedBull Track Club Summertour Baltic See.
