Bike Rollers

thingiverse

Hi everyone! This was a project done during pandemic time. I used materials from my garage. For this project, I used a 90mm diameter drainage pipe, two bearings per roller (6200-2RS), 10mm threaded rods (one per roller), nuts and washers, some wood boards, and lots of ABS filament for the 3D printer. I cut three pieces of 50cm long from the drainage pipe; you can cut them to whatever length you want your roller to be. These three pieces are the roller surfaces where your wheels will roll. I used PVC 10bar water pipe inside for reinforcement, although it's not really necessary (unless you're a heavy rider). On the threaded rod, define the inside bearing stoppers based on the length of your rollers. Use two nuts per side and tighten them against each other. Add a washer on either side of the bearing, then another nut to lock it in place from the outside. I used an original Tacx drive belt for the drive belt. The laterals will depend on your bike's dimensions. My laterals have a total length of 1320mm; the distance between the two rear rollers is 270mm, and the front mounting holes are 970mm, 1000mm, 1030mm, 1060mm, and 1090mm from the middle of the two rear holes. Attached are the Solidworks original files (Solidworks 2017).
