I have loved longtail cargobikes overly since I first saw them. The cargo-racks and tons overdue the rider can siphon stuff, and that makes them the number one nomination when someone wants to eliminate one of the cars from their family’s garage, and get serious well-nigh commuting on an ebike.

Cargobikes that are NOT a Longtail
The Netherlands is one of the most serious countries for willing bicycles into their daily lives, and they have a LOT of cargobikes. Its easy to understand why bikes of all types are popular, considering the land is pretty unappetizing and gasoline is over $8/gallon (2.35 Euro’s per liter as of July 2022). If we squint at the Dutch cargobikes, they do have a few that you don’t see very often in the US, so lets take a quick look.

The Worldwide Longtails
The most famous early longtail cargobike was the Yuba Mundo. An endless-sphere forum member “Teklektik” converted a Mundo to electric with a 2WD system when in 2013. If you want to read increasingly well-nigh this build, click here.
The Rad Wagon by Rad Power bikes uses an unusual 22-inch wheel. They handle potholes largest than the smaller 20-inch, and they are shorter and lighter than the worldwide 26-inch.
There are several models of longtail cargobike that have a 20-inch rear wheel instead of the worldwide 26-inch. This allows the cargo to sit lower, which is expressly helpful if you put a child seat in the rear, with a stocky carpet-crawler in it. I like these a LOT.
The Madsen moreover has a 20-inch wheel in the rear. They can be bought as a factory ebike, or you can buy it without and then add your own kit.

The “Do It Yourself” Longtail
You don’t have to squint very long to see that longtail cargobikes forfeit a premium over a similar frame with no uneaten cargo benefits. However, they are so useful that I spent a lot of time looking at options to get a longtail at a increasingly affordable price. Obviously, you can buy two used bikes from a thrift store, cut them up, and then have a muffler shop weld the parts together (his requires the frames be made from steel).
But there is one really unconfined option, and that is to vendibles the swingarm from a full-suspension mountain velocipede to the drop-outs of a standard bicycle frame.
The pic whilom uses a waterfront cruiser frame, and at the rear is a swingarm from a full suspension mountain velocipede (easily found at a thrift store as a unseemly used bike). A strut-rod was widow from the top of the swingarm instead of a shock absorber.
The type of shock absorbers we find on the cheapest style of mountain bikes are not famous for performing well, but they are a huge resurgence when hitting a pothole, compared to a hard-tail frame. If you squint at the top spar of the swingarm, you can see the two vertical posts where the stock V-brakes would be mounted. Those posts are the part where the shock shield subclass turnout is tying near the front of the shock.
The pic whilom is a close-up of the front shock mount. A 3/16ths thick aluminum plate is cut to fit over the two V-brake mounting posts. Cylindrical sleeves (spacers) are slid over the posts. Washers are placed on top, and a vendibles in each post holds everything down. Once that plate is secured, a cart-wheel mounting subclass is turned upside-down to form a mounting point for the front of the shock.
The pic whilom is flipside view of the zipper of the swinging pivot on the swingarm, and how it mounts to the dropouts on the front frame. Through the waggish selection of spacers and washers, they vendibles right up. If you want a cargo rack in the back, it would have to be tying to the front framework in order for a full suspension swingarm to trundling up and lanugo without jostling the cargo.

Cargobikes in the Third World
There are a lot of aid organizations that have unswayable that steel longtail cargobikes are a vital product that can have a dramatic effect on improving opportunities in rural Africa.
If you are looking to cut and weld a steel bicycle to make a longtail, consider this pic whilom carefully. Professional engineers have ripened this specific configuration as the weightier spherical design. It uses the minimum value of parts and weight, and then arranges them to make the frame the strongest it can be.

What Motor?
A cargobike is the weightier candidate to add an electric motor to the drivetrain, increasingly than any other type of velocipede frame. There are plenty of variegated cargobikes on the market, and many selections have a ebike motor as a factory-installed option. However, if you prefer to add your own ebike kit, which one should you get? Anything would be largest than nothing, but…my favorite ebike motor is the BBSHD from Bafang.
I have ridden over a hundred variegated ebikes over the years, and my favorite by far is the BBSHD. I swapped the chainring for one with fewer teeth (On my Electra Lux Fat 7D), which lowers the top speed and improves the hill-climbing. If you do get the BBSHD kit, fully hoke it and take it for a ride on unappetizing level ground to test the top-speed in top gear. Just for the sake of argument, lets say it can do 35-mph, and you would be happy with 28-mph. the difference of 7-mph is 20% slower than 35-mph, so my goal would be to buy a chainring with 20% fewer teeth.
The stock sprocket (the woebegone frisbee of death) has 46-teeth, so 10% would be 4.6 teeth, and that ways 20% would be 9.2T, sooo…I’d want a chainring with either 34T, 35T, or 36T. The 34T would climb better, and the 36T would be faster on unappetizing land. When I installed the smaller chainring, the hill-climbing worthiness went from good to fantastic. I’m using 52V x 30A = 1500W.
