Looking for a bit of advice. I'm about to replace our school fleet of bikes (12 bikes in total). I've always used reasonable quality bikes to last 5/6 years at a time , but with quite significant service costs . So I'm not convinced paying a lot for a bike is cost effective. This time I'm looking to get something a little cheaper with the view to sell on and replace more frequently. The question is can anyone recommend a mountain bike around the 300-350 mark suitable for a bit of hammer from school groups? Our cycling is typically in the North York Moors and Dalby red route. The decathlon/Halfords bikes look quite tempting!
