Introduction: Bike Dog Walker

We have a pug dog and we also enjoy bicycling. When we go bicycling and take our dog he wants to run, but I have found it very dangerous to hold a leash and ride a bike. If he stops, he can pull on the leash which could cause me to crash.

Parts list:
1. 12" long 1/2"npt pipe
2. 3/4"npt TEE
3. 1/2 to 3/4 bushing
4. Hairpin Cotter Pin to match dog size (25 pound use a 3", and 40 pound use a 4")
5. Extension Spring 1" X 7" X.135"
6. 2 - Hose Clamps for approx. 2" pipe
7. Old inner tube to cut up
8. Leash - 3 foot length see step 8
9. Dog harness

Step 1: Cut the 3/4" Npt Pipe TEE in Half

Cut the 3/4" npt TEE in half. I used a hacksaw, which cut the TEE in half fairly quickly.

Step 2: Grind Sharp Edges Off Cut TEE

Remove the threads inside the TEE, and any sharp edges to prevent scratching the seat post too much.

Step 3: Spring

At the local hardware store buy a closed end spring as shown that is 1" X 7" X.135". If you can't find a spring that is this size, the important thing is to make sure that when the end of the spring is removed, a 1/2 pipe can screw into it.

When I bought this spring at the local hardware store, I walked to the plumbing section and sized up a 1/2 npt pipe to the spring and found that with a little force the spring would screw onto the pipe.

Step 4: Screw the Spring on to the 1/2" Shaft

With the 1/2" pipe in a vise, screw the spring onto the pipe. You need to really push the spring as you twist to make sure it starts to thread on.

I added gorilla tape to help protect the spring for the bit marks from the pliers, however the spring was still marred. You will need to add a lot of tape to protect the spring from marks from the pliers

Step 5: Assemble TEE and Pipe Together

Assemble the 1/2" pipe to the 1/2" - 3/4" bushing to the 3/4" TEE that was cut in step 2.

The great part about this is that when you don't need the "Dog Walker" you can unscrew the 12" pipe and bushing to remove it from your bike. The TEE stays on the seat post out of the way and is ready for when you need it again.

Step 6: Attach Leash to Break-away "Hairpin Cotter Pin"

Size the "Hair pin cotter pin" to match your dogs size. For example: for my 25 pound pug I used a 3" and for my friends dog that is a lab and weighs about 40 pounds I used the 4".

To make the break-away feature work, all you need to do is put the leash in the large loop of the cotter pin and the spring in the small loop of the cotter pin. This configuration has worked well and is very easy to reset after it has been opened.

Step 7: Assemble Bike Dog Walker on the Seat Post

Cut three pieces of old inner tube as follows:
2 at 2-1/4"
1 at 3-1/2"

Insert the 3-1/2" inner tube on the seat post. Then insert the two shorter inner tube pieces and each end of the TEE. Clamp the whole assemble to the seat post with the two hose clamps.

Step 8: Taking It Out for a Test Run

For the first ride it is best for the both of you to go out by yourselves for at least a mile or so until you and your dog get accustomed to the bike dog walker. Then you should be able to ride as a group like in these pictures below.

In these videos you can see that I was using a retractable dog leash, which I would not recommend. I really had to try hard to keep the leash out of the tire, unless you shorten the length.

Update: Aug 8th 2009, we went out for a ride with a yellow lab called "Bell", and a leash that was 3 feet long. That length of 3 feet worked the best for her. So I would like to change my original recommendation of a 6 foot leash, to a 3 foot leash.

I have a basset heeler mix who loves loves loves running, even though she is getting uo there in age. Its pretty easy to know when she is pooped, so I will be adding some sort of dog basket build for this setup so she doesn't have to run the entire ride.

Exercising a dog along side a bike seems to be forced exercise, as the dogs are not constantly running all the time, they often slow down, stop walk abit, their pace varies.

Wouldnt you over heat your dog, if he's constantly running?? While you use minimum power. Do they not get exhausted?

This is just what I need. I got ill a couple of years back and as a consequence my mobility is extremely limited. One of the things that I really really miss is walking my dog - I have it on good authority he misses it too. I've bitten the bullet, overcome my pride and decided to get a mobility scooter - who cares that I'm only 39? My jack Russell, William, pulls quite a lot so this is ideal. I'll whack skis on in winter and yoke him up like a husky.

Thanks for the 'ible. :-)

I decided to go with ubolts thinking it would hold better for dogs that pulls real hard and the dang thing spins. any ideas to clamp it down real tight

These instructions inspired me to build my own. However, I used 3/4" PVC plumbing pipe, threaded adapters and some bungee cord. My 1 year old terrier mix is about 20 pounds and pulls hard. The bungee cord absorbed her lunges and the pvc was strong enough to hold her back. The threaded adapters allow me to unscrew the arm off when not needed. Total cost of materials is about $10 bucks!

I wanted to thank you for the great instructable! Although we did not use the exact same materials, your design was the base for our lighter rendition using plumbing pipe.

It took Sam just minutes to realize what the bike walker was all about and she loved it and was a natural! Even though she respected and followed slow turns we've decided to teach her word commands for turning.

Check out our first go at the bike walker (one photo she wanted to great the camera man):

This is a great design :D I built it today and It works wonderfully :D I made a 2' long elastic leash to clip onto it as well, because my dog is a puller, and it appears my dog doesn't mind being "attached" to my bike. I followed your instructions the whole way and I had minimal issues, such as attaching the spring to the pipe... It was very tricky, and i had to grind the thread down a little in order for the spring to actually fit. but overall that was the only issue :D thank you for such a complete and thorough instructable :D I can't wait to practice with it 2mrw :D

This pug is incredible! Mine would have run for 5 minutes and then he would have just drag along on his back... It is the first not lazy pug I see.

Second: this is genius. I've been wanting my husband to take the greyhound for a bike ride, but she is really skittish and he is afraid something will spook her and she'll run in front of him. This will solve that.

Plus, your video proves to my husband that she is NOT too small to follow a bike. She is taller than a pug! If he can, she can.

Very sweet idea! One could add-on to this idea. I may try it just for fun, but I use the retractable leash with my dog.

Does anyone know how to get a retractable leash that goes around your waste? I have looked and looked, I had one but one of my dogs chewed the cable and wrecked it!

It was so much better than being tugged by arm...and I was able to bike with it on.

I can't wait to make my own. I've want to exercise with our new dog but my knees can't take running and I've been worried about being pulled off the bike holding the leash - she's powerful and loves to run. This will be perfect.

For those of you who say 'get fit with the dog' I'd like to see them try to keep pace with a greyhound or a malamute or any other hunting breed which can't be offleash except for in fenced areas.

I was going to buy a springer but I think I'll make this instead!

I've got two greyhounds and seriously they are the laziest animals on earth and I love them to pieces... my boy actually got off leash one time and he was keeping up with cars going at 60 -70km down the road no problem. (he wasn't chasing but racing them!) thankfully they don't have much stamina and I managed to get him in about 300m... a person I knew was driving and saw me and picked me up.
I take dudley out on the bike but its the braking that is the pain when going gung ho!

Hate to be picky, but doesn't having the "break-away" kind of screw up the whole idea?  If my dog decided to make a pit stop while I was biking, or on my scooter and the break-away disconnected him from the hookup, I would be too afraid that he would run off or run into traffic and be run over before I could get back to grab the leash, which  kind of defeats the purpose of the whole thing. Am I  wrong? Not trying to be nasty, but this ws my first thought.  Did I miss something?

You have a good point, and now that I have used it for about 6 months and seen the comments on this instruct able, I would have to say, if you are using a short leash of less than 2 feet (see comments by Das_Wookie), you don’t need a breakaway feature.  The reason I added the break-away feature was for the case when you and your dog ran on the different sides of a tree or pole.  That would not happen if you had a short leash.  

Author made one for me and it works great! I really like that I don't have to have the pole attached all the time. Now I just have to find a way to train my dog to carry all my snacks and water!

They make dog backpacks. We bought one a long time ago from PetSmart and still use it. Our dog carries his own water/treats and several other items, including our stuff. VERY helpful! :D
