Cargo bikes are very specialized and you don’t see too many of them out on the streets because of that fact. Being uncommon also means they’re rather expensive if you wanted to buy a new one. Like any hardcore bike DIYer, [Mike] got around this issue by building his own out of a couple old bikes. His goal is to show car-dependent people that you can get away with biking most of the time, even if you need to move some stuff from place to place. The build process for this monster was so involved that it required two pages of documentation; Part 1 and Part 2!
There are a few types of cargo bikes. There is the trike (seen often in regular or reverse trike varieties) with a bin between the 2 adjacent wheels. Two-wheeled options are usually either front loaders (the storage area between the rider and the front wheel) or those with rear racks. Mike’s bike is the latter.
He started with a 26″ wheeled bike that was already a Frankenbike of sorts, even the frame alone was a conglomeration of two separate bikes! To start, the rear wheel and chain was discarded. A kid’s mountain bike with 20″ wheels was disassembled and the head tube was cut off. The top and down tubes of the smaller bike were notched so that they fit nicely with the seat tube of the larger bicycle. The two frames were then welded together along with several pieces of support to make sure the bike stayed together through the rigors of riding. The rear rack is made up of some old bike frame tubes and some metal from the frame of a sofa that was being thrown out. Nothing goes to waste at Mike’s place! The 20″ kids bike rear wheel already had a 5 speed cassette so that was a no brainner to re-install. In the end, Mike has a bike that cost him zero dollars and shows the world it is possible to build a utilitarian bike and reduce your dependence on automobiles.

Ever heard of a cargo bike? If you need to carry a lot of stuff around (or maybe even your kid!), then they’re super handy — unfortunately, they aren’t exactly cheap — or common. So you could just make your own…
[Matthew Venn] was inspired by Tom’s cargo bikes, recently featured in issue 12 of Boneshaker magazine. He collected a few scrap bicycles, some steel, and started fabrication — lucky for him, his friend [Eric] has a full metal working shop complete with plasma cutting, MIG welding, and a lathe.
They started by cutting the front end of the bicycle off and replacing it with a much longer steering column. This connects to the only new part they had to buy — a pair of Ford Escort tie rods, which allow you to steer the tiny front wheel. They continued welding the rest of the frame together, testing it as they went — once satisfied with its handling (it still needs brakes) they built the cargo platform and called it a day.
There’s a complete gallery of the process over on [Matthew’s] Flickr, so if you’re hoping to make your own, take a gander!
Need to haul some stuff? Got nothing to haul it with? Then fashion yourself a cargo bicycle! We’ve seen cargo bikes before, but none quite like this one. Built from a German “klapprad”, [Morgan] and his father fashioned a well constructed cargo bicycle which is sure to come in handy for many years.
They started by cutting the bike in half and welding in a 1 meter long square tubing extension. The klapprad style bicycle is made from thick metal stock, making it sturdy and easy to weld. This process also make it a true “stretch” vehicle as opposed to one that replaces the front end in order to keep the handle bar assembly near the rider.
Along with some nicely done woodwork and carbon fiber, they used parts from an old mountain bike including a front fork, front bearing and handlebar, tubing from an old steel lamp, a kickstand from a postman motorcycle,
and a kitchen sink to complete the build. It should handle well so long as the weight of the cargo is not heavier than the weight of the driver.
What has two wheels, is made from five different bikes, and can carry all of your stuff for miles and miles on end?
[Paul Blue’s] DIY Lastenrad, that’s what. (Google Translation)
A Lastenrad is a cargo bike where the load sits in front of the rider rather than being towed behind. [Paul] wanted one for hauling things around town, and rather than buy one, he built one of his own. One thing we particularly like about this build is that the bike borrows parts from five other bicycles that were in various states of disrepair. That kind of re-use is something we can really get behind.
[Paul] estimates the total build cost to be under 50 Euros, which is fantastic considering how useful his Lastenrad is. After logging about 100Km on the bike, he says that it handles quite well, and that even when fully loaded it is extremely easy to make his way about town.
