B2B Cruzbike tandem from two T50s

[Jim Parker]

Yesterday I put up a Youtube video with this description:
We call it the "push-me-pull-you", made by friends of ours who like to make stuff. We donated two T50s and got this back on loan. It's quite fun to ride. Maria loves the clear view to the rear, looking straight into the eyes of overtaking cars. It is definitely more stable and easier to ride with the heavier person in the front. We find it is a wonderful place for great conversations. Our heads are very close together, so it is easy to talk intimately.



We don't plan to manufacture this, but just sharing it here. Here is the video from yesterday.

Love it!

I am planning a MBB longtail cargo bike. I plan on having a seat option for a pessenger. I thought about having a crank for them as well, but it seemed to be hard to integrate well. B2B is worth another thought.

Awesome! I bet it would be really fast with both of you giving it the beans.

A long tail MBB sounds pretty nice. I've always liked the idea of a tandem recumbent.

Nuts. Can we see how the rear crank makes the rear wheel go forwards.........or backwards. I can see it's lsd but can't work it out.

Check out the chain here...

Looks like a hubgear (Shimano Alfine or so)? And of course the chain had to be on the left (viewed from the backseat rider) as you would otherwise have a problem with freewheeling. Nice bit of improvisation engineering.

Hope it will get a place in the Cruzeum at some point

Thankyou frito bandito. I see the chain goes underneath the rear cog so it makes sense now. I couldn't zoom in clearly enough to see that before.

 

[Frito Bandito]

Boreen, I didn't even take a close look at it until today. I just assumed the chain was crossed when this thread first appeared. It is a neat solution though.

I still think a two-wheel drive tandem can work well:

The Perfect Recumbent-DF Draft?

One of my cycling club buddies drafts my recumbent so well. Recently a profesional photographer took a picture and it looked like we are on a tandem :)
