Silencing the Smoby “Be Fun” push trike

In my first post on the Smoby Be Fun Trike I wrote that it is generally a good bargain priced tricycle with a handy push rod. The drawback however was that it was seriously noisy. In my second post I did some good ol’ problem analysis and thought of some ways to solve it. So in this final installment, my solution.

First on what do you need:

• Smoby Be Fun Trike
• An (old) inner tube of a bicycle tyre.
• Scissors
• Ducktape

Seriously that’s all

So what we are going to do is tape the bicycle tire tube to the wheels of the trike.  You start with measuring the circumference of the 3 wheels and cut the old bicycle tyre in according length. Then tape the pieces of tire tube to wheels using your trusty duck tape and there you have it a whopping 15 db noise reduction (remember that every 3 db the sound level is doubled).

There you have it, a simple solution to an annoying problem and one that can be done in 30 minutes with your basic household inventory. Enjoy!

Note: The picture shows my first solution using only ducktape. This worked for a while but after a few weeks of driving, the tape lost its dampening power. So I decided to add the tube for higher durability and increased noise reduction
