Bike Rollers

thingiverse

Hi guys! This was a project done in the pandemic time. I used the materials that I found in my garage. To this project I used 90mm diametreer drainage pipe, 2 bearings per roller (6200-2RS), 10mm threaded rods (one per roller), nuts and washers, some wood boards and lots of ABS filament to the 3D printer. I cutted 3 pieces of 50cm long from the drainage pipe, (please cut the length you want your roller to be). These 3 pieces are the rollers surfaces were your wheels will roll. I used some, PVC 10bar water pipe for the inside reinforcement, despite is not really needed, (only if you are a heavy rider). In the threaded rod you should define the inside bearing stoppers depending of the length of your rollers. Use two nuts per side and tight them one against each other. Use a washer in each side of the bearing, and then one more nut to lock the bearing in place from the outside. For the Drive belt I used an original Tacx drive belt. The laterals will depend of your bike. My laterals have a total length of 1320mm. de distance from 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). You can mount the roller accordingly to this video: https://www.youtube.com/watch?v=pVAtwASKxs4 Alter this project as you like. Have fun and stay safe!
