The last thing one wants when trying to lose weight is efficiency of motion. Cycling is a great alternative to driving (or taking public transit), but it's a horrible alternative to walking until you are at or near your target. Replacing a half-hour walk with a five-minute bike trip rather defeats the purpose.
Walking is great -- you'll need to pick up the distance soon, though, and perhaps make it a daily thing. As you walk more (and as you lose weight) your body will get better at walking. And don't worry too much about the food intake -- learn to listen to your body's needs rather than its wants. It can happen. If you are walking about an hour a day for exercise (along with the normal shuffling about), you should probably be able to get by on something in the neighborhood of 1500 calories -- and that can represent a lot of food if you're eating the right stuff, so feeling hungry doesn't have to be part of the deal. (Keep the time and effort constant -- if you're walking about 3 mph now, you'll find it steps up to 4 mph pretty much by itself. I regularly catch and pass "joggers" these days.)
I've lost just a little bit more than 160 pounds, but I started at a slightly more modest 300-ish (just shy). Just walking, dumping the egregiously horrid foodstuffs and being engaged with the meal I'm eating (rather than absently putting stuff in my mouth while doing other things) did almost all of the work. (Unfortunately, at fifty the skin doesn't quite snap back the way it might have if I'd done it at thirty -- I look way too much like a shar-pei these days.)
It really is about calories in versus calories out. Managing calories in doesn't have to be hard -- it's more about mindfulness than about absolute quantity. It's keeping that arse in gear, even if that means low gear until your capabilities catch up with your ambition, that makes the big difference.
