Free Exercise Bike w/ Laptop Stand

I was working on a lady's laptop, and we got to talking about exercise, and I mentioned my plans to purchase an exercise bike that fit under my desk so that I could exercise on the couch or at work. She said that she had an old exercise bike in her basement that I could have if I wanted. Me, never turning down anything free, took her up on the deal, and I returned to my house with an old DP brand AIR EX2000. Sorry I didn't take any "before" pictures of the bike, but I didn't realize how cool and easy this mod would be.

I did this entire mod in about 1 hour, including finding my tools, disassembling, reassembling, and then taking pictures. I will be uploading the pictures in the morning, but here's the basic walk-through.

Tools Required: 1/2" socket/wrench, adjustable wrench, 14 zip ties, 1 metal coat hanger, exercise bike.

Step 1 - Remove Arms and Pedal Attachments:
On the AIR EX2000 the handles are attached to the pedals via a shaped metal bar. Use the adjustable wrench to remove the nut from the back side of the pedals, and then remove the pedals. Take the attachment bars from the pedals, you won't need the washer and grommet, so you can put them back in the space on the pedals, and then put the pedals back on. Take the arms off the bike with the 1/2" socket/wrench and adjustable wrench. The bar attaching them runs the width of the bike, so it is only necessary to remove one side, then just pull the bar through.

Step 2 - Put Arms On:
Put the arms back on the opposite side they came off of, using the same hardware. make sure the part where you would normally place your hands faces out. Use 2 zip ties on each side to hold the arm bars to the leg bars to prevent the stand from swiveling on the bike.

Step 3 - Attach Pedal Attachments as Stand:
On the AIR EX2000, the braces which attach the pedals to the arm bars have about a 1" zig-zag in them, with one end being about 10", and the other about 4". Using 4 zip ties on each side, attach the holes on the long side of the bracer bars to the holes in the (now) top of the handle bars. Make sure the zig-zag is curved up first, so that your laptop can rest on it. Using 2 more zip ties, tie the holes in the short ends of the braces together in a point (I did mine side-by-side, to make it level).

Step 4 - Laptop Clasp:
To prevent the laptop from sliding from side to side, and also to keep it from accidentally sliding off in case of shock (cats jumping on it), cut the hook part of the hanger off, and straighten it out. Run it through both holes on both sides of the handle bars (the same holes you zip tied the braces to). Bend it up at the width of your laptop, and hook the corners in enough to allow it to snap over the edges of your laptop.

Now my legs are all rubbery, since I've been on the bike the entire time I've been writing this. The seat isn't that comfy, so I'm gonna have to make some modifications to it too, but for now, I have an exercise bike with a laptop stand, completely free of charge.
