What kind of suspension do I have and how do I make it more soft? (I'm quite small)
I've googled and found this bike on Amazon.  Its also listed at a UK site.



Second site lists this at £160 so its firmly in low-spec price range.  Most likely the front fork is based on elastomer and/or a coil spring.

Some questions that discuss the internals of a fork:

What options do I have when replacing my fork&#39;s elastomers?

and this question states typical sag values which you should measure on your bike.

What maintenance does a front suspension fork need?

If you get on the bike and the suspension doesn't sag by 10-25% then you're simply too small and light for the suspension, and softening it could require removing some elastomer or replacing the springs with softer ones.

A more expensive option is to replace the fork with a better one, but this will cost significantly more than the rest of the bike.

As a pseudo-fix you could try adding weight to the front of your bike, with a handlebar bag, front drink bottle cage, or even just getting off the saddle and leaning forward more.
