PVC Bike trailer

PVC Bike trailer
This is fashioned after the bamboo bike trailer, with the addition of a seatpost mount and PVC instead of bamboo. I used the instruction for the wheel mounts, something I need to modify in the future to accomodate heavier loads to relieve axel flex. The PVC is 1" and the trailer bed is 12" wire shelving left over from a home remodel. The wheels are 20" front wheels with bolt-on axel. These are about $24 a piece unless you run a bike shop..hint,hint. The seatpost mount is made by TRAIL-GATOR.com and sells for around $15. My total investment was around $60 for this brand new trailer.
I left the bed flat to acccomodate various uses. We have mounted our dog crate, two plastic crates for groceries, and an athletic bag so far. Maximum load weight tested so far around 50 lbs. The trailer itself is very lightweight.

Great trailer..... to make one that would be stronger what about galvanized metal electric wiring tubing. Also comes with all the elbows and T's, etc, that make easy assembly.
I'm also curious about solid 45* elbow joint, at front of trailer, to tow rod....over time I could see it tear at its bend, as it would be flexing a lot under load. Maybe a couple of inches of hose between front X fitting and the 45* elbow?a large carabiner? piece of conveyor belt?
What is the metal holding axle onto the PVC? Are axles center of trailer, or offset a bit towards rear end?

Very nicely done, but it would be cheaper if you got your material for free just post on crags list. that's were some of my PVC pipe and fittings come from and the city of Seattle, Yelm and Tacoma. for my PVC Bicycles and as to the wheel Problem I had that too but I fixed this to Nice design.

OK so what are the PVC measurements? I am looking at 3' x 3'. Going to use 2' for the platform cuts and 6" for the wheel wells.

OK I changed it to 4" for the wheel wells. Now have to figure out how to mount the wheels.

I've E-mailed the bamboo trailer people several times and asked for directions, but I never get a response. Do you think you could post/send me the instructions?

http://www.carryfreedom.com/bamboo.html Hi, I've seen their site before. don't know how this "link" button works, but here's a try.

Great Idea. Easier fabrication than welding. One suggestion, If you're making this type of wheel arrangement. Get a piece of threaded rod, some nuts and fender washers. Then you can make an axle to hold the wheel mounts in place to align them. It's worth the trouble if you're making more than one.I use it for my welded trailers.

Can you give me some basic instructions on how to "make an axle"? Thanks

Another thought would be to use electric pvc conduit. It is a dull grey color and none to exciting. However, the only difference between the white pvc and the grey, besides obvious, is that the grey has greater uv resistance. It is also a little more costly.. Kudos to you!

I've built a bike trailer and I must be a novice at it...it took quite a few weekends to get it right. The easiest part was building the platform. The devilish part was the wheel. To make a long story short, the whole contraption was wobbling left and right and after a lot of trial and error, I isolated the problem to be with the wheel alignment: the axles have to be precisely in line relative to each other AND the individual wheels have to be nearly perfectly straight. So placing the wheel supports on is more than just fabricating them and drilling them in place on the frame, great care must be given to the above or you'll have a very tough time. Just thought I'd pass this one to save someone a lot of sweat and drilled fingers. Cheers!

Hi! I love what you've done here. Not being a very experienced DIY'er, We're confident that we could figure out the platform and the connection to the bike, but are puzzling over how you hooked the wheels to the cart. Would you be willing to share more photos or info about he exact parts you used to secure the wheels to the platform? The other thing we're wondering is how the connection from cart to bike is handling the torque when you're stopping in a hurry or turning. The bend near the top seems like it might be a possible safety concern. Maybe we're just being paranoid. :-) How has it held up for you with heavier loads? Thank you for sharing! We're psyched to build something that will make us free of the car for hauling groceries, but struggling with a lack of technical know-how.

Nice trailer! I favorited it! Nice trek lime! How are those bikes? I have a trek 4300 mountain bike, but am curious about the lime auto-shift bikes.

Nice job with your ible it looks great!

Very nice. As long as you aren't off-roading with it I think it should hold up nicely. I've heard that UV rays makes PVC brittle and subject to cracking. Spray painting it could block those rays.

Nicely done! PVC is a great alternative to welding, for sure. It looks good on the Lime Lite, too. I work for Trek, FWIW, and you can you can replace the rear 20-tooth cog for a 18t or 16t nexus cog if you want to gear up a little bit. But from your post, I'm guessing you knew that (bike shop guy?). I'd like to see some photos of the underside where you've bolted on the wheels. As for the wire shelving, I could imagine gouging my shins on the little wires sticking off the back. Yowch! Maybe cut them closer to the PVC?

I have permanent scrapes up my leg from bikes, they have a habit of getting the shins with the pedals (metal high grip = Knives on pedals)

I imagine the trailer would provide the similar experience to a passenger...
