    Some people have been asking me about a pulley setup for picking up a bike. I figured I'd put it here too. Here's the basic setup if your only anchor is something on the ground. The board levers the bike upwards. If you can anchor the pulleys high up in the tree then there's no need for the board. More photos.

    Let's see her in the mud with a broken rib or collarbone...


    board=branch.
    pulleys and rope, absolutely (2 pulleys, 2 prussik rope, 20-40m of 8mm rope, 2-4 carabiners, to setup a Z-drag).

    Harbor Freight sells these little rope/pulley setups for $4.99. It packs down pretty well.

    Might get you out of a tight spot....might not.

    (sorry for pursuing the off topic discussion, I think they are worthy notes about other scenarios)

    I initially bought similar block and tackle, but the z-drag setup is more versatile and you get a longer reach for a given length of rope.

    just remember, for security sake, that any knot reduces its rope strength by at least half, and that dragging against mud, rocks and vegetation is increasing the load. Also, a 500lbs block and tackle typically has a rope of much less capacity because of mechanical advantage.

    She is probably smart enough not to be driving a big heavy bike through the mud! There is no way to be prepared for everything. If you are riding alone, it is only common sense to not put yourself in the position where you will have to self rescue. And if you are injured a better piece of equipment might be a "SPOT Satellite GPS Messenger", or cell phone if you have a cell signal.

    Following these instructions, she probably could.

    What makes this method even easier is instead of picking the bike up from a crouched position with your knees bent, if you extend your legs and take tiny baby steps back toward the bike, it comes up so easily that I've actually seen small women throw the bike over on the other side. (They were using my bike. :bluduh)

    While the block and tackle are a neat idea, it's just not practical when there are so many easy ways to just pick the bike up.

    Cheap block and tackle uses nylon pulleys. I would only get all metal ones. A nice braided nylon rope is easy to work with and has many uses too.

    I have never been able to pick up my TEX alone. It's extremely top heavy. When it goes over (without panniers), the wheels are off the ground. The TEX's center of gravity must be above the engine guards unlike a 1200GS. Picking it up is like doing a 600lb deadlift.

    I think the best method for her would be to stand next to it, and look helpless. Ten guys would be stopping to help her immediately. :lol3

    The method I saw at a BMW class (not that I own a BMW) was to pick it up, facing the bike, by the lower handlebar. A woman picked up a GS1200 like that. You get as close as possible, look up (which keeps your back straight) and lift with your legs.

    I mean, the video shows a good'old butt-push technique, but it is mostly useless when one doesn't have an excellent feet grip (which typically is pretty rare around the area you just failed to ride through...) to push at 20-30 degrees

    anyhow, back to the tip:

    So, this plank, if one does fall over often or anticipates to, one can certainly find it worth to carry it around. It can also act as a bench or table, or safe ground to rest the bike on center/side stand overnight, for those camping. Do you have any other unusual purpose for it?

    It got me thinking, the board has to be tall enough for lifting purposes, and large enough to avoid tipping sideways. In fact what you could use is 2 poles resting in triangle with the ground. Maybe aluminum is solid enough and lighter; maybe you can also find something telescopic like in aluminum crutches, to reduce length.

    What do you do if you don't have any trees or bolders to secure your rig to, such as being in the dunes or on a beach? Oh you cut your board in half and make a dead man which you bury with the shovel,did I bring a shovel?, ah, then your remaining board isn't long enough, and you might have forgotten the saw anyway. Then when you unload all the tools you need because they make the bike to heavy , they all sink into the mud . ----If you can't lift your bike , you might be better off with a lighter one.

    No trees, no board, no shovel, no car bumper, no draught horse, no playground swing-set, no riding buddies?

    Then you just pick the son of a bitch up and hope you don't get a hernia or have your hemorrhoids poke out...

    I've never had a problem lifting a dropped bike with just my legs but I can see where some people might. Now that I think about it, you could enhance the leg lift technique with a piece of webbing or a ratchet strap around your neck and attached to the bike at 2 points. Now you have 4 points of lifting.

    Obviously, the best thing to do is to get help.

    Damn, She did a good job lifting although she rested few times before heaving the pig up. Good idea on the kickstand already being deployed which allowed her to simply push up and done.

    I also saw an exhibit during Daytona Bike Week in which ladies, although that maybe pushing the term slightly. Let's say healthy ladies picked up a full dresser Harley but not really valid as the saddle bags kept the bike upright enough that they were able to squeeze under slightly and lift. Can't be done if no saddlebags. YouTube is filled with similar demo.

    <s awesome,="" although="" the="" rope="" seems="" to="" be="" a="" 6mm="" only,="" and="" quite="" short.


    </s>that is nice, although the rope seems a bit small (6mm)

    about prussiks, honestly the pre tied ones are quite annoying and always too long. learn to make a good bend (zeppeling or sheet bend), which allows you to shorten the prussik to an efficient exact length so there isnt any slack when zdragging. I bought pre tied ones just for having the right type of rope (special grip, core and diameter) but I cut the knot away on purpose.

    why not use a game hoist (minus the gambrel)? you can get one at wally-world for less than $20..... add a rachet strap if you need xtra pull....
