Well, some of them use commercial RTOS ( PSOS, vxWorks etc.) and I guess some use propriatory OS, and quite a few probably use linux.
So yes, inheritantly hackable, as there must be linux ports for any likely CPU.
Whether there is an easy way to re-program them is a different matter. Although they must have some way to do it in the factory...:-)
I'd like a schematic and a memory map!;-)
I tried out one of these at a transport show, run by the Company of Cyclists.
Absolutely brilliant fun! It can almost turn on the spot, very fast.
Very impractical for everyday use, but enormous fun.

Get a blue tooth phone, and a bluetooth/USB dongle. Works great, and you can upload ringtones etc as well.
