Hey Babette!
The trailer is a simple stainless steel ladder frame with a custom made axle. Any experienced welder should be able to fabricate one fairly easily.
The box was designed by myself, including the stencil graphic, and then a very handy artist friend helped me build it.
I’ve put on 6,000 km with it so far and it’s still as solid as the day we built it. We have plans to build a few more.
Hi!
Hm ok. In a small country like ours, the range of these stuff aint huge. Will probably have to import the perfect one.
Is there any suspension in your trailer?
Thank you so much for your answers!

No suspension on our trailer. We use super tough German Schwalbe “Marathon” tires slightly deflated for a smooth ride.
The axle and hitch components could be imported from Bikes At Work and the wheels are Skyway Tough Wheels that you can order in many places.

Love this forum topic!
Me too!
Here’s a video of some of the benefits of using cargo bikes…
They’re great - it’s not an idea I can use because I’m not in a city - but the initiative is great.
Funnest commute ever…
When downtown is impossible to negotiate by truck…
Hmm… Might be something I should look into.
I have an electric bike now, and I did modify one of those baby trailers (2kid-heavy duty) into a little cargo trailer by taking off all the trailer’s canvas and adding a little floorboard made from a scrap piece of aluminum ladder off a junked RV. Then, I mounted (bolted on) two big coolers on it. The front cooler housed 3 - 12volt SLA batteries for the 36volt hub motor that I prefer on the front hub to balance the weight better. I had tried a back wheel motor without a trailer and mounted the batteries on a back rack, but it was too much weight on the back tire with me and the batteries. So, with the trailer I decided to redistribute the weight better.
The first bike would fishtail when it got up to speed because it was top heavy from the batteries. The second bike with the trailer made it where you don’t even know the extra weight is there by having the batteries on the trailer. The front hub motor prevented unwanted wheelies on steep hills that the first setup tended to do.
Anyway, I was just tooling around on the rig this summer running errands, so I have not used it for window cleaning yet. I do plan to roll out this spring on it though when the weather is good again. I will get it set up for business over this winter though. So, I will post some pictures here when I get it set up. I love biking, and the electric assist on hills etc cannot be better. I think I should have went with the 48volt - 1000 watt motor though, because the 500 watt motor has trouble on grades when hauling a load. I had 55 pounds of dog food , 30 pounds of cat food and about 25 pounds worth of batteries, and my groceries on my bike trailer, even though it is rated for 100 pounds max, and it hauled it fine. 20 inch BMX bike wheels are stronger if you get good ones.
His mid-drive motor is the best to have for powering all gears for more power and speed. However, they can be expensive, so hence my mention of the use of the cheaper hub motors. I went with cheap SLA (sealed lead-acid) batteries, which are heavy and not energy efficient. They will only give you half power at half charge, where the lithium ions will go full power until the battery is drained. So, the hills on the trip home with a load of groceries was no fun as I lost power with the full load. So, get the best batteries you can and the more amp hours the better because that will give you better range. I plan to upgrade batteries before spring too. I was averaging about 15mph on my bike with the trailer. So, better batteries and a bigger motor will bump that up, but that is really fast enough for a bicycle carrying a heavy load. You need awesome brakes (disc if you can from mountain bike front forks) , and regular bike brakes will work as long as you have/keep them adjusted properly.
This is not the same vendor that I purchased my ebike motor kit from, but it is essentially the same product… (except that my motor requires at least 10 ah batteries and this one requires at least 22ah batteries)

… converting a regular bicycle to electric is not that expensive. I picked up my bike trailer used for around $10. I tried 12 amp hour batteries the first time, and they were weak, so then I stepped up to 20 amp hours and they were better and barely did the job for grocery runs. So, the upgrade to lithium will see another increase in amp hours (30 or more) as well. And since the lithiums are so much lighter and smaller than the SLAs, I may get a second one to double the range since the price of those has come down a little…
Anyway, thanks for those videos guys, because they are really fun to watch.
Happy Holidays guys, and may you all continue to stay covid-free and safe in 2021.
You’re super handy and good at tinkering!
Yes, you’re correct, Mid-drive motors have very strong torque for hill climbing but are high maintenance. I don’t mind as working on ebikes is a passion of mine.
There are some strong hub motors too though. Such as the Bafang geared motors that are not direct drive but utilize planetary gears to increase the motor rpm at slow speeds to get higher torque.
Ride safe and stay happy!
Hello another bike window cleaner here from Canada…
Just wanted to throw up a picture of my set up for the internet to see …i am currently using an electric bike to grow a (mainly) residential window cleaning business. I use an electric fat bike with a 750 watt motor and it’s been fantastic. It tows the ladders effortlessly up hills (not much where I’m from).and cruises between 30-40 kph with a reliable range up to 80kms.(which has been plenty) .
Definitely been looking into adding. A water fed pole component/side of the buisness this year.
Below is the setup that I started off with 2 years ago. It was hard to pedal with fold up ladders in tow but I did what I had to do. It was a very basic setup that helped supplement my income for awhile while saving money to invest in the better setup that I have now.
I am now looking to make this my first year Im going to work full time. I love.my job and the way I do it! Electric bikes rock!
Hope I can help somebody out there that.may be looking for a way to start their own buisness this way.
Cheers
Jordan

hey jordan! we need to hook up i am in winnipeg too. 2048916998 ken
ps lots of room to raise your last years prices
That is a very cool setup Jordan! Good for you man!
Lose a couple pounds while commuting.
Have zero stress driving.
Zero traffic.
Next to zero overhead.
Come home with a big smile on your face.
Dude, you’re doing it 
That’s awesome! I have been trying to figure out how to do a ladder with the Ebike! Can you add a picture showing your connection form the bike to the ladder?!
Here are some photos of our rigs over the years. After 5 years, having tons of fun, and saving 10’s of thousands of dollars, we’ll never go back!
Best 2 pictures I got right now of how I connect the ladders to the bike… basically a milk crate zip tied on to the rear rack… with the ladders connected using a metal chain attached to the milk crate handle… oh and I placed a pool noodle on the last rung of the ladder with a cut in the middle so the chain doesn’t slide around.
It’s been a great way for me to get around.
was the bike for sale or your whole WFP trailer setup with the bike?
It WORKS! thank you and best of hope for you going Fulltime and loving what you do. I keep wondering aloud to my wife about scaling back and only cherry picking my favorite clients, working 4 days a week and biking everywhere but I’m not my own boss with her
