Electrically Powered Bicycle Trailer & Hand Cart (DIY)

electric powered bike trailer

The German-made Carla Cargo is a three-wheeled cycle trailer with an electric assist motor. It can be pulled by any type of bicycle (including a cargo cycle or an electric bike), and it allows you to carry heavy (up to 150 kg) and bulky cargo (a loading platform of 60 x 160 cm). Uncoupled from the bicycle, the Carla Cargo works as a hand cart for large or heavy loads. The vehicle weighs 40 kg including the battery, and has a range of 40 to 60 km.

carla cargo bike trailerThe electric motor is built into the front wheel and can produce 250 watts as a trailer (up to 23 km/h), and 500 watts as a handtruck (up to 6 km/h). The lithium-ion battery has a capacity of 11 or 15 Ah. The vehicle has two disk brakes and a parking brake, which are controlled via the handle or the bicycle handlebar.

The Carlo Cargo sells for about 4,000 euro. The construction manual is freely accessible online, but only in German for now. The trailer/handcart is present at the International Cargo Bike Festival, April 16-17, in Nijmegem, the Netherlands.

Mike Merrell writes us:

“I’ve really enjoyed reading articles on your site since I found the article on the Chinese Wheelbarrow. I stumbled upon it when I was looking for information on the wheelbarrow, and I was immediately hooked. It turned out to be some of my inspiration for our new product we’re calling the Honey Badger Wheel. Our Kickstarter project began March 10th and will run until April 30th.”

“Because you provide awesome content for all of us interested in simple technologies with big benefits, would you be interested in running an article on your site about the modern interpretation of the Chinese Wheelbarrow? My hope is that it would add value to your audience, especially since it’s in line with with new and exciting info for us techies. On a more personal note, I appreciate the boosts of small inspiration from your site that lead to big ideas.”

A Market for Simpler Trucks

low-tech truckThe pace of technological change in trucking over the past decade has been breathtaking. Commercial vehicles rolling off assembly lines now boast standard and optional features that would have been unthinkable on high-end luxury cars just a few years ago.

The proliferation of technology has penetrated virtually every aspect of truck design, from Bluetooth systems that enable drivers to talk on the phone safely to GPS-oriented telematics systems, computer-controlled integrated powertrains and high-pressure common-rail fuel injection systems.

Yet, more fleet managers are becoming less than enthusiastic concerning trucking’s technological explosion. That’s because all the new technology found on today’s commercial vehicles comes with tradeoffs – and many fleets cannot see an end to the new problems that have piggybacked these high-tech models. The most glaring unwanted burden has been skyrocketing truck prices…. At the same time, the exponential leap in new and advanced technologies found on today’s trucks is stressing the industry’s service and support network, which already is struggling with a crippling technician shortage….

Finally, fleet managers say, there is the issue of durability. “I talk to owner-operators leased to our fleet all the time,” says Margret Hogg, general manager of Toronto-based J.G. Drapeau, a long-haul hazmat fleet. “They all drive beautiful old trucks that are dependable day in and day out. They don’t want anything to do with all these new technologies because they run trucks that work when they need them to.”

Hogg believes vehicle reliability has never been lower than it is today. “We still have a 2002 model in our fleet that is far more dependable than a comparable 2012 model,” she says. “We’ve only had six major repairs with the ’02 truck since we got it. In contrast, the ’12 model has already had 11 major breakdowns. That’s not an isolated event, either.”

A Scooter for Everyone

electric scooter johanson3

The Johanson3 is a stable three-wheeler, with the driver leaning back rather than sitting (though sitting is an option). Feet rest on a plate, and pressing down on that plate creates a lean on the front wheel, turning the vehicle while the rear wheels remain solidly on the ground.

That makes for easy on-and off, especially for those who – owing to age, injury, or fashion choice (“skirts, saris, djellabas, and kimonos” are accommodated, according to Johanson3) – cannot throw a leg over a bicycle seat. Various models accommodate single riders or as many as three adults plus two kids, and can haul up to 660lbs of flesh and cargo. Read more: The J3, a trike that hauls freight, spares frocks.

The Johanson3 is available for pre-order and costs $3,150 – $3,900.

Trolleytrucks in Los Angeles

siemens trolleytruck“A project testing a new way to power trucks with electricity is moving forward along selected highway lanes near the Ports of Los Angeles and Long Beach.”

“The South Coast Air Quality Management District, which is the air pollution control agency for all of Orange County and the urban portions of Los Angeles, Riverside and San Bernardino counties, has selected a company to install a catenary system.”

“This is essentially overhead electrical lines that supply trucks with electric power, similar to how modern day trolleys or streetcars are powered on many city streets.”
