This is my second cargo bike build. I wanted this bike to have the same overall length of a regular bike. Space is a premium at my place so the goal was to keep the bike length on the smaller side. The chainstays are super short at 360mm, 20” wheels front and back.

This is totally awesome. Nice work!
Can you share a drawing?
I made a paper drawing of the dual down tubes, everything else I used my rattlecad drawings of a frame that I enjoy riding. Kind of winged it a little.

I love it! What are the specs on the double down tube? Did you have a chance to ride it already and see if they are stiff enough? I am in the planning stage of a similar frame and I am still very unsure how to think about the single tube between the two headtubes. My current plan is a 45 cm 46x2mm tube and wonder how much of an overkill it is.
The double tubes are 1” .035” 4130 from Wick’s Aircraft Supply. I have been riding the bike for a week now and it’s plenty strong and stiff. The front end does not flex at all and the BB is plenty stiff.
The 360mm chainstays make the front end light and easy to come off the ground. Overall I’m very happy with the way it rides and feels.

any pictures of it built up? it’s so rad!
I took it apart to paint it and still waiting for some parts for the final build. This is a pic of the bike as I was building it up to test ride.

Gave it the usual backyard make over. This is my new daily grocery getter. Having cargo on the frame and off the front fork makes a huge difference on how the bike rides.
