Modifying a bike trailer to carry sofas and fridge/freezers and other bulky items?
Hey so iv noticed this app where they pay you to pick up large stuff like sofas. Iv not got a car or van but was wondering of I could fabricate a bike trolley large enough to carry sofas. Or would a cargobike be able to carry such bulky items. Was thinking maybe 2 bike trolleys that can carry 100kg connected together with wood. |
I built my own "heavy hauler" a while ago. Aluminum welding which was a major pain. I need to practice more as I think I'm figuring out why I was having so many issues (trying to run a bead rather than a string of puddles).
https://www.bikeforums.net/attachmen...3&d=1516576524 The original plan for the trailer was a bi-layer frame with an upper section that would be flat, and large stuff could overhang the wheels. Frankly, I use the cargo bike more as a tow machine than for hauling, so my next incarnation will be specialized just for towing. I do prefer a more typical kid's trailer for more compact stuff, and have one that I've gone "skeletal" with. I had intended to strip and rebuild, but it turned out that the fabric floor and sides of the kid's trailer works well for most of my hauling. But, for some bulky things, if it fits on the kid's trailer frame, I'll just take a bare frame. Another plan was to make a telescoping frame using aluminum tubing that would slide into or over the tubing for the kid's trailer, but with the "heavy hauler", it hasn't been a high priority. |
If you have basic steel fabricating and welding skills why not build a licensed Carla Cargo Clone: Bauanleitung Carla Cargo Crowd ? postfossil mobil It is made mainly from ⅝"& ¾ 16 gauge/1.6mm thick mild steel box section. It is economical to build along with being both reasonable light and strong, and the third "tricycle wheel will give additional stability when loaded and is a good starting point for an electric drive conversion.
However, you may need to use google translator because it is written in German. I currently have a friend a few miles away converting the Carla cargo trailer frame I recently built for him to a Romany style bicycle touring caravan like the one in this photo: https://cimg5.ibsrv.net/gimg/bikefor...cffc9f3aa9.jpg |
somebody makes a big bike trailer. is it called "people who bike"? when i do the mayors bike ride here in the city one of the bike shops brings one for helping riders who break down during the ride. looks a little like an aluminum ladder with wheels and a bike trailer hitch.
edit: got the name wrong. it's called "bikes at work" https://www.bikesatwork.com/bike-trailers |
What about using scooter or inline skates for wheels, making the ability for over wide or awkward sizing?

the red one is nice...
|
for which purpose do you use this?
|
and how much cost it required if i make this?
|

I can cut, mitre and mig weld up one of the Carla Cargo frames from scratch in just under 6 hours or 8 hours if tig welding one..... the two caravan Carla Cargo frames I made for my friend were tig welded throughout. They are currently being fitted out; one as a Vardo style caravan and the other as a canvas bow top caravan ready for the impeding summer holidays.... a full set of project photos are to follow upon completion (and there is already talk of a couple of tear drops based on the same running frame for next year). If any one is interested I've copied out the material & cutting list for the Carla Cargo heavy duty bicycle trailer from the link, so just download it from the PDF file link at the bottom of this page, print it off and take it to your local steel supplier and get a quote for the steel. Materials list: To simplify things: Assume 20 x 20 x 1.5 is equal to ¾” x ¾” x 16 gauge ERW square section tubing. Assume 15 x 15 x 1 is equal to ⅝” x ⅝” x 16 gauge ERW square section tubing. Assume 20 x 10 x 1.5 is equal to ¾" x ⅜" x 16 gauge ERW square section tubing ERW: Electrical Resistance Welded is a type of thin walled round, square and rectangular steel tubing.
