A couple of questions that I couldn't find the answers to:
1) Is it law or just recommended that you have a bell on your bike?
2) Can bikes use a dual carriageway where the max speed is the National Speed limit?
law when bought
yes
1) It's a legal requirement that bikes are sold with a bell and reflectors. You can stand outside the shop and remove them and not break the law!
2) Yes but why would you want to?!
What they said.
There's a section of DC that I ride that's maybe 500m long that links some other worthwhile roads (mtn bike on the road with winter tyres whilst the weather was foul just keep the mileage going) so I just wondered.
2) Can bikes use a dual carriageway where the max speed is the National Speed limit?
Unless it's specifically prohibited then yes you can use them. Some sections have specific restrictions, like the A720 Edinburgh Bypass, but these will always be signed.
