To beat the heat this summer, we decided to do something fun, creative and slightly extreme. Jumping the bike into our neighborhood pond seemed like a good candidate. In order to pull off this activity, we needed some sort of ramp to suit different riders, including those who want a higher jump, but also those who care for a lower ramp. Most ramps cannot do this, and are too small anyways. To solve this problem, we set out to design and build our own, adjustable ramp. 

Step 1: Supplies and Materials

For the ramp, we used standard lumber sizes (2x4's and 2x2's). We also used a large, sheet of plywood that was about an inch thick, give or take a few 64th's. The hardware that we used consists of 2-1/2" screws, 1-1/4" screws, a dozen miscellaneous  screws, and two 3" clevis pins. We also used two sets of two hinges. The size of these doesn't really matter, as long as they aren't super flimsy. The miscellaneous screws that we mentioned are used to attach the hinges to the large plywood, so make sure they are short enough so they don't poke out on one side of the sheet. 

- 1.25" screws 
- 2.5" screws
- Misc. fasteners (under one inch)
- 3" clevis pins
- 4 heavy-duty door hinges

- 2x2's supporting main sheet of plywood: 78" (x2)
- Large sheet of plywood: 74" x 26" x ≈1"
- Long, base 2x4's: 8' (x2)
- Base end stop 2x4: 26"
- Support brace 2x4: 26"
- Support leg 2x4's: 27" (x2)
- Cross beams on base 2x4's: 19" (2x)
- Stops for height settings: 3.5" x 3.5" (6x)
- Small plywood sheet (for threshold): 29" x 14" x 1/2"
- Threshold 2x2's: 15" (x2)
- Threshold support 2x2: 20"

- Drill
- Drill bits 
- Chop saw or hand saw
- Rotary tool (dremel)

We tried to build one for my <a href="http://www.youtube.com/watch?v=VxTZDjzOaJ8" style="color: black;text-decoration: none;">car</a> but it didn't work so well.
This is sweet i made this and i was coming off a big hill and i went like 10 yds
Thanks to everyone that voted! We were runners up.
Awesome! How deep is the pond?
At least 10ft in that spot. Probably more.
Sweet, but what happens to the bike?
We strapped a life jacket to it to slow it from sinking, but we have to remember to get it before it does sink.
That's smart. I was thinking, though, if that bike sunk ten feet deep, it would be hell trying to get it back up! :)
meh, it'd be worse if it was like 14 feet, that was something i will never do again.
I used to do this... Duct tape two 2 liter bottles to the bike and it wont sink at all!
And now put E.T. in the basket, and take a jump at full moon...
<br> Your thumbnail image caught my attention <sub>(let that be a lesson to people)</sub>, video, the rest - quality, I like it.<br> <br> L<br>
This looks like &quot;clean&quot; summer fun. Thanks for the idea, adjustable is definitely the way to go
great idea making the angle adustable!!
so sweet!!!!
