Using the TURBOSPOKE Bicycle Exhaust System is super easy. First, find a suitable place on your bike (it fits either side) and attach the exhaust system. You can adjust the 3 Motocards to get different motorcycle sounds - just play around with the 2 - stage tuneable feature. When you start cycling, you'll immediately hear those awesome motorcycle sounds. As for maintenance, since it's 100% waterproof, you don't have to worry too much about getting it wet. But it's a good idea to check the connections regularly to make sure everything is secure. There's no need to replace batteries as it doesn't use them, so you can enjoy the sounds hassle - free.
