01:07 Step 1 - Base sketch
04:32 Step 2 - Centerline sketch
08:33 Step 3 - Draw headtube
12:19 Step 4 - BB ST
14:47 Step 5 - Front triangle
18:49 Step 6 - CS centerlines
22:14 Step 7 - Tire clearance body
23:45 Step 8 - SS centerlines
27:46 Step 9 - CS body
29:36 Step 10 - SS body
31:20 Step 11 - Joining the dropouts and yoke
34:59 Step 12 - Conclusions
In this tutorial, we will design a mountain bike frame from scratch. The method I show is a simplified version of the way that I design bikes in fusion360. Just with any software, there is going to be a learning curve.

Tips:
- Break down the video into steps. You may need to repeat steps at 1/2 speed to understand
- Try not to deviate from the tutorial on the first pass. You can always go back and change the geometry and design later
- If you are stuck, try reverse-engineering the CAD
- Just with anything, you only get better with practice
This is fantastic. Thank you! I am just starting my bike building journey, an the design was my first roadblock. This gives me the confidence to tackle it. I really appreciate it.
Thanks for the video and the forum I’m learning a lot of new things and planning to build a frame this year! I’m not familiar with Fusion but have worked with Solidworks before, the principles are very similar. I guess for further “automatisation” or “fast-forward-process” you could setup some clever relations. For example for the SS Tire clearance your dimensions were driven by the angles, however the driving dimension is actually the bending radius (depending of the tools you have), the SS Diameter and the tire clearance you want to achieve. With this you could set the arc’s center to be a projection from the arcs midpoint to the tire center, and the midpoint be at a certain distance from the tire (clearance). Your bend angle and segment distance will update accordingly. Also for the inward distance in TT and DT on the HT you could probably (not too sure about this tbh) have the distance driven by the Diameter Tube you are planning to use and maybe the angle it hits the HT (so that the actual Tube diameter always sits e.g. 7mm under the HT too Surface. In Solidworks one could have “Glabal Variables” (not sure if this really was the name for it) as a table where you could enter in dimensions that later were used in the model. I think an Excel import/export was also possible. With this Nick could give you an excel sheet with all measurements and the model would update 100% automatically taking into account all variables and dependencies.
Anyway looking forward to see more of your inspiring work, thank you!
This was a really excellent tutorial, thank you for putting it together!
tipp for both Dropouts. When selecting the origin for the joints pay close attention to the orientation of the dropouts coordinate system. When hovering over the sketch line just before reaching the end point the joints system differs from selecting the point directly. Then position is right and orientation matches the sketch. Took me ages figuring it out.
thx for the great video btw
Thanks for the video, first good fusion tutorial!
Thank you so much, please do more videos!
Very Good Video, Thanks,
@10:08 you can just hold the left mouse button and the program will show a list of the lines that are on top of each other. Then you can choose the line without hiding the other sketch
I knew there had to be a better way of doing this! Thanks!
Can you do that again a single pivot full suspension bike?
Your videos are awesome! Informative and digestible. So easy to follow. Do you have a video for designing forks? Or any tips for designing forks?
At 20:51 can you explain the exact key strokes to get the 2 arcs and the last tangent line? It's not turning out for me.
Nevermind. You show how to fix it at 26:12.
Informative tutorial it is! Wondering if you need to print the design out? If so, we'd love to help. Meanwhile, not sure if you are interested in any cooepration together? (PCBWay zoey)
"see the thread for files and more info" Where is the thread?
Opps sorry, fixed it!
Thank you for your video, what are your constraint settings please? I keep getting the “sketch geometry is over constrained”
Usually when "skech geometry is over constrained" it means you accidentily created a sketch contraint. Usually its a midpoint, parallel, or perpendicular constraint that you did not intend to have. The only way to fix it is to hover over all the sketch constraints, find the unintentional ones, then delete!
I don’t get the link for Personal Use 😢
