This is the Turbospoke device, it is in effect a fake but noisy exhaust system designed for kid’s bikes, it uses a card to stick through the spokes and the exhaust system amplifies this sound to make it more real and life like. There must be plenty of people around today that remember doing something very similar with a playing card and a clothes peg to hold it on to the frame.
Here are some of the features for the brilliant Turbospoke fake noisy exhaust system;
Turbospoke not only has the look and feel of a real motorbike exhaust pipe, it also makes the most awesome realistic engine sounds. The engine sounds start as soon as the wheels turn, so the sound changes as your speed does! What’s more is that Turbospoke requires no batteries to make it work, it is 100% pedal powered.
Priced at around £15
