1. The spokes hit the card
The Motocard is held firmly in the black clamp with one end of the Motocard against the spokes of the wheel. When the wheel spins the spokes hit the card and it begins to vibrate. The vibration makes the engine sound which is captured inside the clamp.
2. Each card makes a different sound
Each Motocard has a different shape. The different shapes mean that each card vibrates in a different way when the spokes hit it. This means that a range of engine sounds are made. Each card also has two ‘power-slots’ so you can actually tune the sounds yourself by adjusting how much of the card is in contact with the spokes. Try it out and race against your friends!
3. And the exhaust makes it louder!
The sound passes from the clamp up through the silver exhaust and out the awesome looking tailpipe. You’ll be amazed how much the exhaust increases the sound. You can test it out by running your Turbospoke with the exhaust removed. For a really raw sound remove the tailpipe and get the full-bore experience!!
Motocards - How long do they last?
Motocards are made from a type of plastic called polypropylene or PP for short, which has been specially formulated to withstand the impact of the spokes against the card. What's more, they are totally waterproof and last for ages! Compared to the old playing card trick they are a lot louder and much more durable!
Over time, with lots of use, you will notice that the "Power Zone" area of the card may fray slightly and the print can fade. This is totally normal and is due to the spokes rubbing on the card. But don't worry! As long as the card is in contact with the spokes, it will continue to produce awesome engine sounds. You may even discover some new sounds. When your cards do eventually wear out or you just want some new ones, extra sets will be available from the store where you bought your Turbospoke or online at the Turbospoke Store.
Oh, and they cost less than the price of a comic too!
