If you've got a question about using the free online version of BikeCAD, post it here.
I am finishing an E-Copper build and looking forward to starting my next one. Unfortunately, the company that made the frames I like is not making them anymore. So now I have the opportunity to design my idea. I know what I want, but I do not know how to reach that point. I built a computer just for this issue.
I did take mechanical drawing in school, but that was close to 30 years ago.
Unfortunately, I am also doing this alone. Trying to start my own business building custom E-Choppers both in bicycle and motorcycle styles.
Hello,
I just noticed in the seatstay auxillery views of my current bicycle project that the seatstays seem to overlap at the junction between the two seat stays and the seat tube. I am wondering if bikeCad is already equipped to model a miter like this. I am also wondering if overlap of the seatstays is advisable in a bike design, as it seems few of the bikes I have have such a feature. I suppose the seat stay junction could be widened at the top tube, but I am trying to ensure the angles at the dropouts remains 9 degrees, and since this is my first frame I am also trying to avoid having to bend any tubes.
Thanks for your help
Hello
For my first bike frame I am planning to use the rear dropouts pictured below.
As can be seen, these dropouts have plugs that are meant to fit snugly inside the chainstay and seatstay tubes. What I would prefer though is that the tubes extend directly from the plugs without any change in angle. I am wondering if bikecad has a means of telling that the stays are perfectly parallel with the direction that they are extending too, which are indicated in the above drawing with lines KK and MM.
In my current bikeCAD model, it seems that the chainstays in particular do not point in the same direction as the original dropouts, which I worry may be a problem. Is their a way to ensure the angle the dropouts and stays point perfectly match?
I am trying to determine the exact tube lengths for the bike I am trying to make. In the picture below I have added some dimensions to the top tube and down tube that are supposed to go from the extreme end of one miter to the extreme end of the miter on the opposite end of the tube. From a visual glance these dimensions seem to be accurate, but I am having a hard time telling if the dimensions are actually parallel to the center line travelling along the length of the tube. I am also wondering why the exact length of tube accounting for miters is already present for the seat tube, but not on down tube and top tube.
Thanks for the help
I just started this program and have no clue what I'm doing. I'm currently trying to build a bike of my own and am inputting my demensions into bikecad but it seems the headtube is excessively long. Is there anyway I can shorten it or put the right demension on it?
I drew up -to my best ability- the measurements of the Columbus 29r curved seat tube in the tube section.
When I select to display the seat tube angle of my CAD frameset drawing, is the angle measured from the bottom bracket centre to the top centre of the seat tube, or is it just the angle of the long/straight main length portion of the tube?
Thanks in advance.
Is the comprehensive Fit adviser only avaible on the purchased verion of BikeCAD?
The quick start only give me saddle hight.
I am trying to adjust the chainstays and seatstays in BikeCAD so that the angle of the stays relative to the plane of the dropouts is exactly 9 degrees, which is what this angle should be according to the schematics of the rear dropouts I am using. I am trying to calculate this angle so that I can directly plug that chainstays onto the rear dropouts when I assemble the frame. If there is a way for bikecad free version to show this angle automatically that would be extremely helpful. I have attached some images that should clarify what I am looking for in more detail. If it helps, the rear dropouts I am planning on are called Rear track dropouts with eyelets - plug style - 11mm SS & CS - 66° SS/CS from Framebuilder supply.
Hey Brent
Whenever I upgrade to the latest version of bikecad (which I've only done two or three times total), I lose all my saved components, templates, etc...
I solve this by copying all the files from BikeCAD_XX.X_configuration folder and pasting them in the new version.
Is there a more formal way to do this migration? If not, can I request this as a feature? I'd love the option to simply import settings, component library, and templates from the previously installed version.
Thanks!Justin
Is there a way to view the chainstays and seatstays from the top of the bike so I can check clearances to the tires?
