Hi Louise.
Nice bike, I just had alook at the web site for Ridge back. It is a fast street racer, For commuting or perhaps courier work. Ridge back seem to try and cover as many angles as possible by then saying you could put nobbly tyres on and go off road as well if you want. Think about why you need the bike and what you will be usingit for? If you want to go hurtling around the streets, bumping up kerbs then fine, but if you just want a nice sedate ride to work then get a hybrid or a touring bike.
Or indeed if off roading is your thing then go for an all out Mountain bike!
Or possibly you just want something to look good on, Well I reckon it would definatley tick that box!
