OP here!

Thanks everyone who got to take the survey before it got moved to the survey section, then deleted. Sorry I missed that section to begin with - I didn't mean to come in here and break the forum rules.

We do appreciate the feedback - positive or negative - but I thought I would come on and add some detail to the concept. The idea is indeed to create a combined bicycle helmet & lock targeted at your everyday urban biker or commuter. We hope to provide a cost savings on the total package while helping to avoid the awkward transportation of a lock and the need to carry your helmet with you.

The basic concept is for a three piece helmet as seen in the rough picture below. The top of the helmet will flip up and out of the way. The other two pieces can wrap around the bike to secure it. It would have a lock in the front.

There are clearly a lot of challenges with the design but before we address those we want to validate that the market exists and see if it is willing to pay a price that would be required to address those challenges. Please keep in mind this is a school project.

Thanks again for all the feedback! I'm hesitant to provide a link to the survey again, but please let me know if you want it.

btw, I liked a lot of the ideas above - wish we had thought of those :-)

Here is a very rough idea of the concept:
