Introduction: Bicycle Trailer Hitch - Quick Release Hose Coupling.

I saw this design on a folding bike and thought it awesome. I used to hitch my bike trailers with a lashed inner tube, but this is faster and more convenient. Works very nicely.

Step 1: Obtain Necessary Hose and Pneumatic Release Components.

1 x male 3/8"
1 x female 3/8"
1 x 3/8" threaded coupling.
hose to fit tight on 3/8"
2 x hoseclamps

Step 2: Place Hose Over Pneumatic Fitting

screwing it on worked well.

Step 3: Secure With Hose Clamp


Step 4: Same for Both Male and Female Coupling


Step 5: Drill Hose in Appropriate Places for Attaching to Frame


Step 6: Make Frame Attachment (on Pannier Rack)


Step 7: Attach Hose to Pannier Rack

lock nuts!

Step 8: Attach Hose to Trailer Handle

PRETTY SELF EXPLANATORY THIS ONE...

Step 9: Ride Happily Away to the Store to Carry Buckets of Stuff.

    Would this set up , work on a trailer that has 20 inch bmx wheels mounted in bike suspension forks , and where the actual bike trailer frame is just below the level of the rear bike rack.

    I found out that I had the wheels in the center of the trailer, causing it to be almost perfectly balanced. This was causing it to sway from side to side. I moved the wheels farther back, putting more weight on the tongue. This solved my problem.

    Just wanted to help here and say that , in step 4 and 5, if you were to clamp the area to be drilled flat with something it would be alot easier to drill :)

    this is a great idea. I know more than a hand full of folks that have been trying to figure out alternative hitch ideas,. thanks for the post..


    also if you had any idea what happened after i read this <3

    Can you show or explain how you used to hitch with a lashed innertube?

    I've been working along the same vein, i'll have to post how i built my hitches, here's pictures, on my second trailer i used a 3/8" drive rachet u- joint instead of a hose, way less surging than the hose.

    That's a good source for a UJ: I'll remember that one. Trying hard to think where I'd get an aluminium one: any ideas?

    It might be worth adding safety lines through both the maie and female ends (one attached to the bike around the screw through the pipe, and one attached to the handle around the screw attached to the handle, which could be tied together and stuffed into the interior of the connection upon joining, to ensure fail-safe strength in case the whole assembly pulled apart (unlikely)...

    I really dont see it ever coming apart. (yes, you are right VERY unlikely) I used to work with air tools all day fulltime at a auto repair shop (and at home) and they never came apart unless we wanted them to. This was with us putting that connection unde various stress all the time, snags, twist, bumps, drops, etc.

    Anyone who has or is building a bike trailer will find that the biggest dilemma is a connection to the bike with an easy range of movement for turning.   This is a fantastic idea, but are the hoseclamps strong enough to hold when pulling a heavier load?   I'm sure they are if you really crank em in tight, but seems like they might slip off.  Have you had any troubles?

    I really like your design! In the I tried this with regular radiator hose, and the hose fatigued and fell apart, making the trailer gooseneck fly into the rear wheel and break at least 5 spokes as I ground to a halt. The pneumatic coupling is a excellent idea! You will be seeing this on my 2nd generation trailer.

    That's the coolest idea I have seen in a long time. Fixes so many issues with the trailer smacking the tire... Nice job.

    Very cool, I'm going to use this as a starting point for my first trailer. I'm thinking of going with one of those plastic foot-lockers so I can lock it up.

    Excellent! Do you have any trouble with the trailer (when loaded down with frosty beverages or the like) coming to a stop? I'd be worried about it bashing into my back tire. I think I'll give this one a try. All hail the grocery-bike.
