Exercises done in bed or (wheel)chair

You can use an arm ergometer. It's where you can cycle your arms instead of your legs.

I've been doing this sometimes. Learned the exercise during a physical therapy.:D

100+ lbs in 14 weeks??? That is plain and simple crazy, why on earth would you think that is a good idea?

Look at 1-2lbs weight loss a week, but really you don't want drastic weight loss, it is very unhealthy.

Adjust your goal. It's not realistic or healthy. With that much weight to lose you can lose 3 pounds a week but don't set yourself up here for failure. Be good to yourself and accept that what you want is to change your habits for good. That takes time.

Get in your wheelchair and go join a gym. You can use barbells and TRX straps. If you're lucky you will find a gym with a trainer who specializes in working around these limitations.

If you don't want to go to a gym yet, then use dumbbells and work out in your chair. Over head presses would be a good one. But set getting into a gym as your goal. It will open up a new world.

Now is not the time to focus on weight loss. You need to be very careful about what you eat. Remember everything that you eat should be geared towards helping your body heal. I had Achilles surgery last year and created a few exercises. 1) The bed roll up. Lay sideways on your bed with your legs hanging over at the knee. Try to roll yourself up to a seated position without using your hands or straining your back. If you can't make it all the way up, just do a sit up as far as you can without straining your back. 2) side lying leg lift. Think of the splint as an ankle weight . Lay on your side with legs stacked. Lift top leg up ten times, slightly forward ten times , slightly back ten times and do small circles with your top leg counterclockwise and clockwise. Make sure you move your legs often to avoid blood clots. Another good one is while sitting in bed, lift leg and try to "draw" the letters of the alphabet with your foot. You can do bicep curls and all kinds of arm stuff just sitting there. You can hook your tube to a door jamb and do seated rows from you wheelchair.- just make sure the breaks are on! I found I didn't need to do to much upper body because just dragging myself around on crutches was a lot .. Drink green tea an dark cherry juice. Helps with inflammation. Good luck.
