More than just cutesy front baskets and simple rear racks, bicycle cargo hauling has become serious business. Joining big-load tools like the Velove Armadillo, the German-designed Carla Cargo electric bicycle trailer upgrades your bike for loads up to 330 lb (150 kg) and 53 cu ft (1.5 cu m). Not only can it power those loads behind your bike, but it also unhitches and rolls as a powered hand truck.

We've seen electric bike trailers before, including the Rollout Brouhaha and Ridekick, but the Carla trailer presents big, next-level cargo-hauling muscle. Even when it's not strapped down with a big, ol' 53-cu ft load of boxes, its sheer size is immediately apparent from the three-wheeled configuration and 63 x 23.6-in (160 x 60-cm) bed.

We don't even want to think about the calf pains that would be involved with towing a Carla trailer via pedaling alone, and that's okay because we don't have to. Designed to work with both regular bicycles and electric bikes, the trailer pulls its own weight.

The e-drive system offers a power-start function (up to 1 mph/6 km/h) to get the heavy load rolling from stop. A crank sensor on the cyclist's bike tracks pedaling, adjusting motor output accordingly, just like a pedelec bike. The front wheel-mounted motor provides 250 watts of continuous power, supporting speeds up to 14 mph (23 km/h). So all that cargo rolls along smoothly without weighing the cyclist down like a school bus strapped to a strongman.

The swappable 11 Ah lithium battery offers up to 25 miles (40 km) of range. There's also a 15 Ah (37 mi/60 km) battery upgrade available.

The Carla Cargo trailer rides on 20-in wheels with Schwalbe Big Apple Plus tires. Stopping power is provided by an overrun brake system with dual discs, and there's also a manual parking brake. Unlike other bike trailers that secure to the bike's rear hub, this 88-lb (40-kg) trailer clamps to the seat post via a tow bar.

A bicycle trailer may be smaller and more versatile than a motor vehicle trailer, but there are still plenty of places where you can't tow a trailer or even ride a bike. When you arrive at such a place, say a shopping mall, you don't necessarily have to pull over and start unloading. The Carla trailer detaches from the bicycle and works as a powered hand truck so you can keep right on rolling to and through the front door. It includes a handle, thumb throttle and brake and rolls at speeds up to 1 mph.

The fully loaded Carla Cargo electric trailer starts at around €4,000 (approx. US$4,550), before taxes and shipping. Weekend gear-hauling warriors might balk at that price, but the trailer is designed more for business use. Carla sees it as a solution for organizations like parcel services, community agricultural groups, and food and beverage vendors. Plus, Carla offers DIY plans (German) for those that want to save some money. Accessories like an aluminum cargo box and protective tarp are also available.

And if 330 lb and 53 cu ft sound too limited, Carla Cargo has also recently played around with a setup of its trailer hitched to a Radkutsche Musketier cargo e-trike, a combination that offers 882 lb (400 kg) and 141 cu ft (4 cu m) of pedal-assisted hauling potential.

Very cool! A smaller one wheel version would be nice for most people who just need it for regular shopping. I am surprised at the 330 lb weight limit, I would think a trailer with 3 wheels could handle more. It seems to use a standard 250w motor with a 11 Ah lithium battery, so the price tag of US$4,550 seems a bit much. A Evelo Aries bike with 14 Ah battery, 500 watt mid-drive with a NuVinci N360 drive train is $2500. So you think a trailer would be a bit less, but it is probably hand made. I still think electric trailers able to easily switch between bikes is one of the smarter ways of going electric. Especially if you add a solar cover. :)

May work in Europe for local goods, but in North America the distances are further than most would want or are able to travel. Especially considering they must share the roadway with cars, trucks, all traveling at much faster speed... Unless you live near a big box store, pick-ups & vans will rule.

I did not read anything about a parking break, nor did I read about a reverse gear. Did I miss them? I would think that these features would be essential.

great article. the newest video you can see here in german with alot of cool impressions: http://www.swr.de/landesschau-aktuell/bw/suedbaden/gruenderboom-und-raumnot-die-ideenschmiede-in-freiburg/-/id=1552/did=17262182/nid=1552/1jkz717/index.html#utm_source=Twitter&utm_medium=referral&utm_campaign=SWR%2Ede%20like

Not bad ....as usual the price is too much....I'd put a "ProGo ''propane powered motor just above the electric front wheel, and use the electric motor in / around stores......then on the road use the 25cc propane motor on the road ,1-16.4lb cylinder of propane = up to 20mph /for 2 hours or about 40miles, with the right gearing and being propane it is just as ''Green'' as the electric motor would be,since its on a trailer you could get a refillable 1 gal.propane tank and ride for 10 hours for $1.90,you would have to charge a battery 10-15 times to get the same mileage,and wait 4-8 hours per charge!! If you know what you are doing the propane motor would power up the battery,whenever it got low so you have a ''Hybrid bike!!''......LOL :-)

Who ever that "Unklmurray''guy is,must be really out there........His comment doesn't make much since........some rambling about using a propane powered scooter motor?????.......I like the cargo trailer idea,The walking speed of 1 mph though is kinda slow [ the average 5.5ft human walks at a speed of 3.5-4miles per hour,at a normal speed ] so the speed of 1mph, may be fast by European standards,butt to me is only about %25, of normal-Slow--.......... I ride a Trike to begin with so I don't need a trailer that is also a trike......butt I do like this cargo trailer.............LOL :-)
