Bought a Carrera bike at Halfords 6 months ago. I go on it twice a week mostly on roads and cycle paths. Within that time, Ive had to take it back 3 times. Once for a air puncture and twice for a snapped chain. None of this included in the warranty and they insinuate I should have bought the repair care package so I would have got all that included. What I find incredibly cheeky though is that when they repaired it the first time they vaguely alluded to the gear mechanic not being aligned with the chain (after they fixed it) and that has led to it snapping off again. Then they try and upsell you to buy chain cleaners/degreasers to get more money out of you and to excuse the faults I've been getting but shouldnt have happened. Definitely going somewhere else if it should happen (which I'm expecting it to).
