I've been a mountain biker some years back, and now I'm looking to get back on track. I'd like to buy a new bike to start with and i'm eyeing this one because the price is ok:

I'd use it to ride to work in the city and go on some hill tracks on weekends, but nothing pro/competition-style. But I'd definitely like a good, reliable bike which will serve me well for years, and which can handle some of the rougher off-road tracks. What do you think about Wheeler brand and this particular model?
