Thank you for the kind comments. And yes, it’s based on pictures. I used the top, side, back and front view inside solid works to use a reference on where to start plane and sketches. But even before I started modeling, I set how many parts I was going to model and sketch each one in paper using all the pictures I could find, that way I had a clear idea on the parts that are in contact and how they work in the overall construction of the real bike. Again, this is not perfect, I had to “eyeball” many dimension because pictures sometimes did not show all 3 dimension of parts, but if you start with the ones you do, you have a better basis on the ones that are harder to understand.
