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.

Love, Love, LOVE!!!

Every night we go for a family bike ride. We absolutely LOVE the Electric Assist! It has been such a game changer. We love to go to the grocery store, go get shaved ice or go out to dinner. We can go EVERYWHERE! I have owned my bike for 3 years now. It wasn’t until this year that we bought the Assist. It has been so much fun. So much easier to get up those hills. Buy it!!! Worth EVERY memory. ❤️

Life Changing

My wife and I loved our Madsen, but with the e-assist, it is so much better. We seriously fight to run errands in it, because they are so much fun. It is a much better alternative to a second car for us.

Madsen Cycles

Thank you, Ben! We love hearing how the e-assist has made your Madsen even better. So glad it has become a second car alternative!

We LOVE the Electric Assist!

We purchased our Madsen bike last summer and have been using it whenever we get the chance. 2 kids turned into 3, and they only keep getting bigger and heavier, and it was getting increasingly difficult to ride comfortably in our hilly neighborhood. We finally decided to add the electric assist, and my only complaint is that I didn’t do it earlier! It makes riding the bike so much more enjoyable, as I am no longer exhausted just getting to the top of my street. The amount of assist is just right (and can be adjusted using the simple controller which attaches to the handlebars). I can still get the leg burning workout when I choose, but I love that I am no longer restricted to really short rides around my block. Great job Jared and team!!

1st Generation 2009 Madsen Electrified

I purchased the first generation Madsen bike back in 2009, and have been loving it for years. Now with the kids getting older, this has turned into our beach cargo carrier. Hauling chairs, coolers...a grill on occasion. The electric assist kit makes hauling anything around extremely easy. The custom mounting bracket is genius, and makes installation simple. I needed a couple of modifications for my 1st generation model, and the Madsen team (Jared, Lisa and Mindy) were ready and willing to help me out. Don't be intimidated with the install. The YouTube installation video, and Jared's phone support is all you need to get this installed on ANY Madsen bike. I can't recommend this electric assist kit enough. I'm looking forward to loading up the Madsen and cruising down to the beach this weekend!

Thank you for the review, Mike! So glad the e-assist kit has added even more fun-filled adventures to your Madsen bike experience. It truly is a game-changer.

The E-Assist is a serious game changer

I've had my Madsen for about a year and a half and absolutely love it. My family uses it almost every single day. We recently added an e-assist to it and it has seriously changed the game. I live in a very steep hilly area and I have 2 children that are fairly heavy. Add in their two heavy bikes and whatever gear we've brought for the day and those hills used to be very daunting. The e-assist has had absolutely no problems with those serious grades-it's fun!- and has expanded our range significantly. The battery lasts far longer than expected-I've yet to get down to the lowest bar and I've taken it on extremely long rides primarily up hill. The only tricky thing is you need to continue to shift as you go and there isn't really a set in stone way to be sure that you're in the right gear. This just takes practice memorizing your terrain and learning which gear you need to be in for that particular grade. When in doubt, you can turn the assist to 0 for a minute and see what feels right as you're pedaling to guage where you need to be for the assist. You'll start to learn what the mechanism should sound and feel like when it's in the correct gear-you just have to pay attention. I am also happy that it still works on family bike rides with others who don't have an e-bike. There are 9 different levels of assist and I can stay at my son's pace in the 3-5 setting range. I absolutely would recommend this product!!!!

Madsen Cycles

Dallin, thank you so much for the detailed review of your e-assist. So glad you decided to go for it with those big hills in your neighborhood. I know you already used your bike a lot, and now you'll use it even more!! Cheers to many more bucket bike adventures.
