Hi. I've used bike cad for road bikes many times. There used to be a way to choose to start a mountain bike or road bike design from the launch page. WIth this latest version, I can't see how to do this. When I click "Quick start" I am automatically given a road bike template. Frustrating.
Bicycle Design Software
There are three ways to start BikeCAD described here. To start a mountain bike design, find a mountain bike you'd like to base your design upon in the Design Archive and start BikeCAD according to the instructions above.
Here's a quick link to a mountain bike design from the archive that might suit you.
thanks!
