Nice job on the weight loss. I'm trying to shed a little myself, down about 3lb in the last month.
A lot of people recommend weekly weigh ins and I think that's fine, but personally I go the other way. I weigh myself 2x/day (before bed, when I wake up). I only ever look at the "moving average". So technically my scale said I weighed 171 this morning but my moving average is at 174. So, imo, I weigh 174. The moving average shows a smooth straight downward line, wheras the daily weigh ins are all over the place. Makes it very hard to lie to yourself.
I've been on the indoor bike a bunch myself. And hating it.
Oh, I managed to get signed up to Zwift, though, although I haven't tried it yet. It's a cycling MMO. They take readings from your power meter, HRM, speed etc and use those as inputs to control your avatar. I think you can ride with AI riders, real riders, or both, in races or "group rides" etc. I haven't actually tried it yet.
All you'd need is a little ANT+ usb stick - I don't remember what mine cost me, $10 or $20. I have this one:

It's more or less plug-and-play.
At the moment Zwift is in beta, you sign up and after a day or 2 they give you an account. At some point they will start charging for it. Oh, and when you do rides they can upload to strava with "real" GPS tracks, strava segments, etc. Pretty crazy.
