It's an interesting idea, but it seems like that in order to make the bike sellable, one would just have to replace the bar part on the bike. Since it rotates, it's probably a piece that can be replaced relatively easily.

The seat also needs an easy way to mark or put it back in at the same height. But that could be done I would think.

Do like the idea of not having to carry a separate lock...

Personally, I don't like it. My u lock mounts to my bike. It's heavy, but I can switch it between bikes also. If I had that, I would be limited to only taking that bike out in public.

Two issues with this. First,you have to use their frame,it would be prolly be fairly expensive to retrofit this to a current bike. Second,what if the lock fails or you loose the key? I've had two friends who had issues with their bike locks. One was finally able to open it after spending a good 45min playing with it,the other needed to come back and cut his lock. If the mechanism jams,or the key breaks off,or you just loose your keys,a regular lock can be cut and the bike is fine. With this system,the bike's unrideable until you get it fixed.

Did anyone notice the bike used was a single speed? Without a fixed down tube, you can't mount the required cables necessary for front and rear derailleurs! In other words, you're stuck riding a single speed. No thanks.

Totally impractical IMO but it looks like it would have been a really fun and satisfying engineering and tinkering project so I like it in that respect.

+1 for out of the box thinking, -2 for treehugger.com, a greenwashing purchase PR effort by discovery communications that i stopped paying attention to several years ago (i am huge on sustainability).

I gave that design some thought today and it really seems impractical for someone like me at least.

I was thinking about this bike and it's strange method of locking will only create more attempts to steal your bike! Most crooks will simply think the bike has been abandoned and try to pull it apart to free it from it's position so they can ride off. In doing so, they may very well damage the lock and your bike!

It's at least different. I'm not sure how practical it is in the real world.

You don't need a downtube to route cables to the rear...

Many bikes run their cables across the TT. I actually prefer it.

Good point.

However, the bike being sold did not have the ability to attach cables on the top tube. Maybe someone should inform the maker of this design to include build this feature into the frame.

Expect to see a picture from Manhattan of a Yerka frame locked to a post...with no wheels.

meh. +1 for thoughtfulness, but what a pain to have to reposition your seat every single time. goodbye dialed in bike fit! I mean I guess you you could mark the tube with a sharpie or something, but having to make sure its straight every time and everthing. I noticed in the video she just shoves it all the way down.

Well, it's clever at least. Better than most of the industrial design student attempts I've seen.
