SpringerHands Free Dog Leash Bike Attachment Kit -Pet Exerciser for Running, Walking Jogging - Universal Fit for Bicycles - Quick Release, 18-Inch Rope

This thing is just awesome. Before getting this, I tried biking my dog (a 45 pound Samoyed) simply using a leash. However, she is a sled dog trained to mush, so she always tries to get in front of the bike and pull. Also, she is a little shy of the bike, so when she gets tired, she goes next to me but at the full length of the leash. so we are taking up the whole path. I almost killed myself a few times trying to make sure she didn't get in anybody's way, so I decided to try one of these products for walking dogs on bikes.Now, I got one of those walkydog things that is simply a spring in a tube that sticks off the bike. They are a lot cheaper, but there is a reason for that. I have no problem with the quality of that product, it just didn't do for me quite what I wanted. Yes, it kept her closer to the bike and at my side, but I felt like she could still easily get too close and get hit by a pedal or a wheel because there was still nothing between her and the bike. Despite that, it now seemed that she had too little freedom to move around, like I could hurt her if I stopped suddenly (however, this thing turned out to be great when used instead for urban mushing using a regular leash without a real bungee tow line).So then I decided to try this one, and it worked wonders. I've only used it a couple times now, and I really feel like both the dog and I are a lot safer. Now, I did hesitate with the crappy plastic attachments that everyone was complaining about, because my dog is a sled dog and she can pull like crazy, so I did an experiment and put a loose leash on her as well so that the leash would hold her if the plastic thing broke off. After two fairly long rides, nothing broke, so I'm not too worried. Even if you plan on using your own makeshift bit of leash instead of their weird safetly thing though, this product is worth it.The spring action is just perfect, keeping my dog comfortably at my side but still giving her some freedom with gentle resistance while keeping her away from the wheels and pedals. She's still a little uncomfortable being that close to the bike, so she leans sideways against the pull of the spring a bit while running, but she does that less when she gets tired, so I think the more we use this, the more she will get used to it and stop leaning. However, even when she leans or gets distracted, I stay perfectly balanced and in control, never feeling like she is going to pull me over or anything.All in all, I think this is a great product and I would highly recommend it.

My dog loves it. Solid construction.The people that say it loosens up didn't install it correctly. When you put the spring on, you spin it like a threaded nut. Clamps are very tight to the frame. My dog pulls very hard and it never slips.

The media could not be loaded. The Springer has given me the gift of safely exercising two highly energetic Chessies at once while I get my exercise on my hand-cycle. It took my husband a few weeks of trial-and-error to attach the exerciser and I'm so glad he finally made it work for the hand-cycle.The attachment as sold is designed for typical bicycles, but if you have a hand-cyle, which is like an adult tricycle, there really is no way to conveniently attach it. My hand-cycle is wheelchair height, and I operate it like one when I need to go in reverse, so I presume it will also work for wheelchairs. The key is to have a raised bar to attach the Springer, otherwise, it will be too low and the leash will interfere with the wheels when the dogs pull me ahead.Here's my husband's genius idea to attach the springer:He got these parts from the local home improvement store:1 heavy duty padded arm hanger2 - 3 feet long vinyl coated galvanized cables*4 - double ended snap hook3 hose clamps2 sets of the aluminum ferrule and stop set4 cable ties1 screw that match the size of the bolt that comes with the springerFrom the Container Store:1 elfa utility large basket* We found that if the cable is too long, it can get caught in the wheels, so it was a matter of trial and error to find the perfect length that works for my bike. You will need to adjust this length to your bike. The length we arrived at gives our dogs enough room to run alongside me without getting their paws run over.I found the elfa basket to be the perfect width and size to store things behind the seat like treats, water bottles, drinking cups, poop bag holder, garage door opener, baby wipes (my hands get dirty from handling the wheels), etc. My husband used the cable ties to attach the basket to the bike. The basket has turned out to be one of the best accessories we got for the bike.My husband attached the arm hanger to the bottom of the seat. He then attached the springer to the hanger as high as it will go in order for the galvanized cable leashes to clear the wheels. The metal on the Springer is heavy and needs reinforcement, so he secured it with a second screw in order to balance the product's entire weight on the bike otherwise it feels loose and unsecured, which is why I rated this 4 stars. We found the plastic ring to be extremely weak, which is why we replaced with the double-ended snap hook cables. They hook onto the springer on one end and the dogs' pulling harnesses on the other. To keep the dogs from getting tangled up with each other, I also attach a leash to their collars that attach to the handcycle grip.Just for experimental purposes, I tried to go biking with the dogs without the Springer and they pulled me in all directions. I felt every tug and jerky motions. Once they are attached to the Springer, I could not feel much of their tugging because the attachment absorbs most of the force. When the dogs see a bird or squirrel and want to go after it, I can feel a slight tug and have enough time to steer in the opposite direction. After biking for over 600 miles, the Springer is still holding up to our show ponies. Many people at the park have asked about the springer and I have pointed them here to get theirs.
