So I Bought…a bicycle sidecar

I’ve been so excited about this purchase, that I’m going to get this article published earlier than usual. I like to use something for a few months before I write about it, but this one is already getting a lot of attention, so I’m going to start here and update as time progresses.

Sidecars. I read that they gained popularity in WWII to easily transport two people (or cargo) with one motorcycle. They were practical and stylish. But then automotive manufacturing changed to mass production then cars became more affordable. Then the demand for sidecars dwindled, and manufacturers met the demand and stopped production.

But so many things come back in vogue if you wait long enough, and sidecars might be coming back – but for bicycles more than motorcycles. I don’t know enough about vehicular trends to speak about them, but I can tell you that the moment I saw a nice bicycle sidecar I gasped and wanted one.
So I bought one, and I love it.

Three months and $3,000 later, I finally have a bespoke sidecar for my kid & ebike! #LadyJupiter #ScandinavianSideBike #WorthIt

So I bought…a bicycle sidecar.

A basic definition of a bicycle sidecar is a partially enclosed passenger seat that attaches to the side of a bicycle. That’s my personal definition at least.

Q. What sparked the purchase?
A. I wish I remember! I think I saw one on Pinterest and immediately fell in love. Easy.

Initial Concerns
I needed to know if the sidecar I fell in love with would actually mount onto my newest ebike. When I got serious about the sidecar I was already waiting on my RadMini ST2, and I couldn’t find specific details about the mounting bracket online – so I didn’t have any measurements or detailed photos to work with. I asked the sidecar dealer (who presumably asked the maker), and received their assurance that the bracket wouldn’t be a problem – so I trusted them. Three months and $3,000 later I had the sidecar mounting bracket in hand and confirmed that YES, the bracket fits my bike. Whew, that was a high stakes gamble.

Repeat. Scandinavian Side Bike’s long bracket fits on a RadMini ST2. You’ll need to remove the cord wrap from the bike frame to get the bracket nice and tight, but that is easy. You’ll also need to remove the derailleur guard from the frame. The sidecar bracket actually protects the derailleur, so you’re not losing that function.

Clarification for anybody I just confused

  • My electric bike is a RadMini ST2
    • Rad = referencing the seller;
    • Mini = model [the only folding model at the time of writing]
    • ST = frame type = ST is short for step through
    • 2 = generation; sequential logic. The next MiniST will be the RadMini ST3
  • The sidecar is made by Scandinavian Side Bike
  • Mad Dogs & Englishmen (MD&E) is the USA dealer for Scandinavian Side Bike


  1. I fell in love with a bicycle sidecar photo online.
  2. Bought a RadMini ST2 when ebike portability became more important to me (further details in Public Note; re: comparing RadCity ST3 and RadRunner+).
  3. Got serious about sidecars, and wrote about that research journey in Public Note; re: shopping for a sidecar. I thought my kid would love it too.
  4. Was worried because none of the Scandinavian Side Bike cars in photos or videos were on Rad Bikes. Lack of visual proof delayed my purchase until they assured me that the bracket would fit the geometry.
  5. My salesperson at Mad Dogs & Englishmen called me and we confirmed details – white sidecar, black striping, number 13 decal, red seat, red rain hood, one child seat, one seatbelt, eyebolts for dogs, black fender, two brackets.
  6. I paid just under $3,000 over the phone.
  7. SURPRISE! 89 days later USPS delivered the sidecar to my porch.
  8. I had to reach out for detailed installation instructions…I was supposed to receive instructions long before the product. For the record, I also never received any shipping information either – so the dealer dropped the ball, but the maker definitely came through [by providing detailed instructions in English, and confirmed that I am missing the extra mounting bracket I ordered].
  9. I mounted the bracket to my bike!
    1. Working with a RadMini ST2 & Scandinavian Side Bike’s long bracket
    2. Removed the cord cover from the bike
    3. Removed the derailleur guard
    4. Firmly attached the sidecar bracket to the bike frame
  10. I turned the bike on for a quick maiden voyage, and…bupkis; I had power and lights but no motor or throttle. I emailed Rad immediately, and in three business days Rad helped me fix my no-throttle issue – thank you Tyler!
    [My motor connector just needed some attention, easy fix.]
  11. Learned that my kid needs time warming up to the sidecar. I’m taking it slow so that it’s a positive experience.
  12. Received the second bracket – yay! This one is for Mister Jupiter’s RadRunner Plus. I’ll install it in a few months, no rush on this one.

So that’s where we are now

  • the sidecar is on my bike and I love it
  • my kid is warming up to it – no requests to ride in it yet

And now…we wait.

  1. Soooo.. I’ve gone down this rabbit hole and been obsessing over getting the same sidecar, I was hoping you could share how you’ve found it? Did you get the amount of use out of it you were hoping for? Any niggles after using it for a while now? I’m close to pulling the trigger so would love to know how you got on. Thanks 😊


    1. Of course!

      I think I found out about this specific sidecar on Pinterest – but I honestly don’t recall. It was a rabbit hole for me too, and the one that I bought was exactly what I had in mind.

      The amount of use isn’t exactly what I expected, but that’s because of my horrendous pollen allergies and location (I don’t live in a cycle-friendly area; no bike lanes, and nothing worth biking to anyway).
      My kid has been going on rides with his dad while I stay indoors…near the air filters and my inhaler 😭 🫁 We’ll be moving later this year – hopefully I’ll be able to go on more rides myself!


  2. I’m thinking of getting the exact same one for my wife’s RAD ST, but wanted to know the ease of putting it together/detaching for ttransport in a car.

    Thank you

    1. The ease is subjective, and will certainly vary per person (specifically body size and muscle mass), and per vehicle. The sidecar is much easier to heft around than the folded bike – it’s lighter, but larger. If she can easily fold and load the bike into a car, then the sidecar will be a breeze!

      And depending on the car, you may want to look at a bike rack for the ST. The sidecar occupies my entire trunk (Prius), so I got a Hollywood rack to move the bike. It’s a great setup overall. Like all things the assembly and disassembly with be slow in the beginning, but will get easier and faster with practice.
