New bike trailer build. = CHEAP, too.

I just put this together & gave it a test ride . Works just fine, but I will move axle forward to about the center of the bed. The way I have it, now, I can easily remove the long tongue & re-use it as a garden cart. I got used cart for $25 , metal tubing & all hardware for another $10 . I have $35 total in it.

Basically, it was a cart like this design, that I bought used.
http://www.northerntool.com/shop/too...8229_200308229

It has 20" wheels with ball bearing axles. [ a MUST] From a local metal scrap yard, I got a piece of 1" square aluminum tubing, 8 ft long, plus about 2 ft of flat aluminum 1/4" x 1 1/2" wide. This was used at the 2 bends in the tubing as braces, one for each side with each end cut at 45 angles, & bolted to the tubing. I bent the tubing in a vise, but with aluminum, you have to be careful not to bend too much, then have to bend back, because it can break there. The small flat pieces work fine. Tubing is bolted through the bottom of the wooden bed, another bolt to the cart " handle. I then cut the tubing to the right length allowing the trailer to be able swivel behind the bike. I attached the tubing to a piece of web strapping about 18" long. 2 bolts hold the strapping to the tubing plus I put another bolt thru both sides of the strap only, closer to the seatpost . This keeps the end of the tubing from hitting the seatpost. There is a little slack in the loop to allow the trailer to twist & tilt at the connection. I will probably move the axle forward to the center of the trailer. Notice the front " leg " of the original cart, which I tucked back under the bed . It is easy to remove the parts & re-use the cart for it's original purpose. Trial run went well with the cart easily pulled behind the bike using an extra gear or two.

[ sorry for so many typing errors ]

I like this one! You should post it in the sticky thread on the top of this site.

I bought plans for a cart like this one online just a few months ago, I`ll see if i can find the site i bought it from. Been thinking of posting some of my similar projects here since I am using gardencarts more and more and working on using them for hand and bike.

Found a old "milk cart" for heavy duty hand pulling at the recycling center this summer. I`ll take it to the welder this autumn for repairs but also thinking of converting it to use on a bike also.

One is a child biketrailer converted to a gardencart, but can easily be converted back. I like carts of all sorts.

That cart is very similar in design. Note; The plans calls for 3/4" plywood to be used && that is heavy. I could lighten my cart by using aluminum sheet, " aluminum diamond-plate ," from a scrap iron site, too. I live in flat Florida, so weight doesn't bother me very much. I can take some more pix if anyone is interested.

i think it depends on the use really. The guy with the plans said if you use it for heavy duty (bricks and stones) it can break if plywood is too thin. If weight is important plywood can be thinner or diferent material as you suggest. Also it is possible to replace broken plywood once in a while if weight is more important than strenght.
