Make your own gangline elevator (aka "Scooter Noodle")
To make your own gangline elevator you will need the following supplies, all of which you should be able to purchase from your local hardware store for around $5. The tools required are all common household items that most people will already own.
**Please note: The length of bungee cord needed is directly proportional to the size of the tire. This set of instructions is based on a standard 24” adult bicycle tire.
-3/8th bungee cord 4 feet long.
-1” PVC pipe 12 inches long.
-3/16th Nylon Rope 2 feet long.
-1/2 inch Swivel Bolt Snap
-5/16th Wire Rope Clip
-Ratchet with socket to fit rope clip bolts (in this case: 13mm)
-Electric Drill with drill bit one size larger than your nylon rope (in this case: 1/4”).
Drill a hole slightly bigger in diameter than your nylon rope approximately 1” from the end of your PVC pipe.
Knot one end of the nylon rope and thread it through the PVC pipe and out the hole. The knot should be large enough to prevent it from slipping out the hole even when decent pulling force is applied.
Thread the bungee cord through the swivel snap, until each side is of equal length. Take the ends of the bungee cord and thread them down the length of the PVC pipe (starting from the end with the hole). Your set up should now look like the image below.
Slip the two bungee cord ends approximately 1-1.5 inches through the wire clip. Use a ratchet to tighten the bolts (you will need to alternate between the bolts several times while you tighten) until you cannot move the bungee cord when you pull on it strongly.
Warning: This is one of the most critical components. If the wire clip is not tight enough and the bungee cord slips out, your dog will end up running freely down the road without you.
The gangline elevator is now ready to be attached to your bike. Double check the security of the bungee cord and nylon rope by give them a good pull. If either of them shift, go back and make the knot bigger or re-tighten the bolts.
Attaching the gangline elevator to your bike will depend on the individual bike. For this slightly modified mountain bike, I wrapped the bungee cord around the front post and slipped the PVC pipe through the middle. The nylon rope is tied to the handlebar extension. I gave it enough lift so that even with downward pressure (from the dog) the gangline elevator wouldn't take off my front reflector.
Warning: Be sure to test your brakes after installing the gangline elevator to make sure it won't interfere with the cabling. If possible, have a friend pull on the swivel snap (imitating a dog pulling you) while you test them.
If after reading all of this you decide that building your own is not for you. You can purchase a gangline elevator through the company Alpine Outfitters. They make a commercial version that goes by the name "Scooter Noodle".
That's it! If you have any questions feel free to leave a note in the comment section.
