Turbospoke brings this simple idea right up-to-date and allows parents to share this wonderful childhood experience with their own children.Turbospoke - the Bicycle Exhaust System makes any bike look and sound like a motorbike!! It attaches to a child's bike in under 5 minutes and using durable plastic cards and a realistic megaphone exhaust pipe it makes awesome motorcycle sounds as you cycle. The sound is generated by the card vibrating in the spokes of the bicycle wheel and the exhaust pipe captures the sound and amplifies it. The harder you pedal, the better it sounds. It looks cool, sounds awesome and transforms kids bikes! Turbospoke is also very rare for a toy product as it has been seen more than 25million times on YouTube.
