The Triban will feel faster than the flat barred bikes from
Evans due to being lighter and having narrower tyres running at higher pressures, but all will be serviceable for your needs. You don't need the suspension forks on the Mongoose, they only add weight for little extra comfort. Why not get the Ridgeback Speed? You a rack and mudguards which you will surely need. The b'Twin also looks good. Inevitably bikes at this price are going to be compromised for quality somewhere but you can just replace the offending components when they fail which shouldn't be too soon.
Whatever you get don't forget a lock, helmet, puncture repair kit, tyre levers and a spare inner tube.
If you have a
Halfords near you pop in there to have a look, they have some good budget bikes or check out the website. How about:
