A few decades ago anything under 32 lbs. was considered a "lightweight". The hills haven't gotten any bigger since then.

If there's a lockout on the suspension that will save you some energy climbing the hills. Getting some tires for it with a smooth tread will help in general.

Weight is relative which is why you don't get consistent messages from the reviews. There are a lot lighter bikes out there. The suspension is partly responsible for the extra weight and really isn't necessary on the street unless the roads are just terrible.
