The seat is the Thule YEPP Junior Easy Fix, which is for some reason hard to come by here in Europe. The bag is the Maurice G. frame bag from Gusti Leather (https://www.gusti-leather.com/frame-bag-bike-bags-bike-frame-bag-leather-bag-vintage-brown-leather-2f6-20-5wp). It fits perfectly into that space.

My original springs broke early on, but I now have 1000 miles on my RadWagon with this setup. Get some small hose clamps and attach as shown in photo.

Thanks I'll try that.

Hello,
my RadWagon 4 is set up like this. I have 2 kids on it (3 and 7) as well as 2 ortlieb panniers. To be able to attach the panniers I used paracord loops with small pieces of pipe on them (see attached pictures). This works very well.

Hi msantiago1256,
the RadWagon4 does support Thule Yepp EasyFit. If you take the deckpad off you will see the rectangular hole where you can attach any EasyFit seat.
I have the Yepp Junior EasyFit, you can also attach the Yepp Maxi EasyFit.
I didnt find any other seats besides the Yepp that would attach there.

Hello gibbarts,
I am not having any problems with hills. I can go up a 10% slope at about 16 mph. Also with the Kids on it, no problem. The steepest slopes I had at maybe 25% were slowing me to about 6.5 mph. But weight is a considerable factor and I am very light with my 150 lbs. With me and my wife on it feels much slower, but that is with about 300 lbs on it.
I am only using the European version with 250w and a max speed of 16 mph.
With the previous answer I do not agree. The Radwagon 3 did not have a geared motor and thus much less torque. 7 gears are also no problem it does not give you less range only fewer increments.

Where to? I ordered in Germany in September and called the support. They said the bikes were produced but could not leave the sea port in China for an extensive time. In mid/late Jan. the bikes should be there and most accessories as well.
