Let's be honest, despite the dislike on here and other enthusiast fora, they do what they do pretty well and they sell some solid bikes and accessories at a decent price. I've bought a kid's Carrera from there and it was great, a proper bike, well set up too... I'd probably avoid the Apollo range but the rest are decent. The Bike hut tools I've had have been excellent.
Not all the staff have the best knowledge, sure, but it's clearly a place that appeals to newer cyclists looking for a very straightforward and good value transaction and the offerings are at least a big step up from supermarket bikes. Maybe newer cyclists find the expertise of a local specialist a little daunting or confusing, so that might be a factor?
Anyway they're doing something right and I'm certainly not averse to going in for a mooch.
