Family Adventures Made Eco-Friendly with Electric Cargo Bikes

An adventure awaits your family with a MADSEN electric cargo bike. Sporting a colorful and beautiful design, your kids will have so much fun riding in the spacious bucket and creating memories outdoors. Plus, you’ll be doing your part in caring for the environment by leaving the car at home.

Electric Cargo Bikes

What makes e-cargo bikes awesome is that they make pedaling easier. With pedal assist, the power kicks in to give you a boost when you pedal. You’ll be flying up those hills in style with the kids, dog and groceries in tow.

You also control your power level and speed, so that you can ride at your comfort level and with as much assist as you want (or don’t want).

Savoring the Outdoors

Did you know that studies show that green spaces improve one’s mood and refresh the mind? Your electric bike is your ticket to a great time outdoors. It’s also a perfect way to give kids a break from their countless screens, and instead be outdoors making memories and being active.

Spend Time with Your Family

Take your children outside and create lasting memories together. By nature, kids love spaces where they can roam and play. Pack sandwiches and drinks and head to the park. The kids will love riding in the bucket and feeling the wind in their faces. And you will love the conversations you can share with them while riding.

An electric cargo bike is not just for family adventures…you can also get ALL the errands done! The bucket will carry your groceries, dry cleaning, library books – you name it, without the hassle of traffic and refueling your car. You can take your kids to soccer practice, ballet classes, and art museums. You can even bring your pet along for the ride. The MADSEN cargo bike has a weight capacity of 600 pounds…and that’s a lot of cargo! The e-assist will help you carry it all.

Caring for the Environment

By riding an e-bike with your family, you are doing your part for the environment. You minimize your carbon footprint and take advantage of better energy sources. What a great example to show kids one way to be eco-responsible.

Take your family on fun and eco-friendly adventures today! Contact MADSEN for inquiries about our bikes.

So fun!

I got this kit for my older (2012?) Madsen and even though I don't have a lot of technical expertise, I planned to install it myself as a project. I had to ask for a little help from my local bike shop with the removal of the crank and bottom bracket, and then for a little help getting the gear shift back in order, but I did the rest myself, had a ton of fun, and LOVE my bike with the electric assist. I want to take it everywhere, and I have no worries about hills or a heavy load. It's bringing new life to my bike!

With the video tutorial, DIY installation is pretty easy

Just installed this on our Bucket Bike we bought back in 2019. You need a couple of special tools and a tiny bit of know-how, but with the video on YouTube, it is fairly easy. I would say the hardest part is getting through the INCREDIBLE packaging that the kit comes in. I recommend watching the entire video first, reading the comments for info on tools you need, then following along as you install. The e-assist kit makes an already excellent bike even better.

Electric Assist Kit on Madsen Bike

We have a couple of small kids and a few hills around our home. With the ebike kit for the Madsen, we can all go on a ride as a family and get up those hills with ease! We are big fans!!!

Total game changer

We've had our Madsen for three years and just added the e-assist now that we have 4 kids 7 and under. We live in a hilly area and I wasn't feeling safe on the bike anymore because the weight was too much for me to handle. We put the e-assist on a month ago and now we are using it multiple times a week. I was worried I wouldn't get a workout anymore, but I was pleasantly surprised that I can add just enough assist to help me feel secure but still work out, and when I'm getting wornout I can crank it up and confidently get home. It was a huge investment, but to experience this with my kids while they are young is completely worth it!

We're so glad that you'll be able to continue making memories with your kids! Thank you for your feedback. Safe riding!

Electric assist :)

This has been a game changer for sure! Had my madsen bike for a little over a year without it and purchased it this spring. Having the electric asssit has been soooo nice especially on hills! Now peddling my kiddos around isn’t such a chore but I still get a work out in :)
