Now this project is close to my heart.

A cycling friend asked if I could make a rocker base for his turbo trainer. This allow the trainer and bike to rock gently from side to side to create a more natural feeling, add comfort and reduce stress on the bike frame.

I wanted to design something that would be strong, adjustable, portable, and easy to store when not in use. After experimenting with different spring options, I opted for a simple tennis ball solution, inexpensive and easy to replace.

My finished design can be adapted to fit most of the popular turbo trainers. And it is easy to adjust the rocking motion to suit individual riders.
