Well, I think I understand what you are getting at. From what I remember from some of your reports, motorists in Bahrain are crazy, hence the security trucks front and rear, to act as a rolling safety barrier for the cyclists.

This would require that most of the people riding worked the same shift and got off at a specified time and have the same route of course. It sounds like your situation might fit the bill.

I haven't ever heard of bike buses, except with respect to school children. No reason it couldn't work as long as you could get support from your fellow co-workers.

But then, personally I avoid group rides whenever possible.

Good luck on your project. Keep us informed.
