Training Bike Stopper (No Supports)
thingiverse
I discovered that my exercise bike could be used in both directions, this allowed me to sit on a comfortable seat behind it (my couch for right now) and bicycle in a recumbent mode, however the bicycle would slide forward easily. This is probably not useful to a lot of people, but I decided to upload it anyway. You'll need an antiglide mat for this, if you have another size mat, then you can easily change the size to fit by selecting the lowest edges and scaling in XY.
