If you’re in the market for a secondhand junior full-suspension mountain bike then it’s well worth a look at the Forme Black Rock 26 if one is available.
Price wise it sat in that mid way point between a hard tail mountain bike and the much more expensive full suspension bikes that will set you back several thousand quid.
Having hit the sweet spot in terms of pricing, Forme took the learnings from their adult Black Rocks mountain bike range and their junior Kinder range and melded it into the Black Rocks 26, giving you a good entry level full suspension bike.
