    Need advice on building a Portable Mini Ramp for DJ Bike

    MUST BE SMALL ENOUGH AND LIGHT ENOUGH TO CARRY 1 HANDED WHILE RIDING

    What dimensions do you think would be small enough to achieve this but still big enough to be useful for a 26" wheel size dj bike?

    Specific questions:
    - What length, width, height?
    - What thickness of plywood top? 1/2 inch?
    - What to use for supports? 1x1 or 2x4 or something else?
    - What radius would you use? Keep in mind I enjoy flowy / launch type jumps more than steep jumps

    Thanks for all the advice in advance.

    I built one similar to Seth's - a little longer and a little bigger....But I also made an attachable base with 4 additional settings to move it up and down. Made it very versatile. There's probably cooler ways but I'll try to snap a pic over the next day or two. I have the flu so not eager about moving at the moment.

    As you can see - two parts... The main jump and then a super booster (ha) for some height progression options. Use with it or with out. I made my wider, longer and taller than Seth's. 2X4, screws and real plywood not OSB.

    How much would you say the jump without the addition box weighs?

    With that sort of limitation, you're better off sticking to bunnyhops.

    Have you seen this video yet? Plastic toy store ramp with a set of backpack straps on it.

    Just a complete guess on weight but maybe 40lbs? 30lbs?

    Yeah, my intention was to build one more portable than Seth's #1 big ramp but bigger and taller than his #2 portable one. I needed one to purposely session where no jumps exist not so much an impromtu - "Hey this would be a great place for a jump..oh look there's one in my pocket. How convenient!"

    Anyway - Seth's #2 sounds best: https://www.youtube.com/watch?v=4j2JnSnCsPU

    Open the video description and all the measurements are there - watch the video.

    Ps - The plastic one is sort of neat.

    As long as the framework is solid you could probably use a thin plywood. Definitely construct it with appropriate length screws. I imagine 1x3s would be plenty strong for the support beams under the plywood deck and would save a little weight over 2x4s. You could get really creative and install straps to the side to carry like a backpack. I don't think I'd wanna hump around a portable ramp on my back for too long of distances though- if you go with wood I'd imagine it'll weight at least 20 pounds.

    This isn't mine, I just took a pic of it at Whistler.



    If you're going for distance, especially on a long-travel full suspension bike, there is definitely something to be said for a long-wheelbase ramp. Short abrupt ramps are not good for full-sus bikes. This is from Winter Park:


    Angles - help!

    For my little practice layout at home I use car ramps, the type sold for doing oil changes and such. They make them in plastic and I think some designs can be stacked, so you could carry a couple and they can't weigh much.
    No adjustability though.
