I suggest sealant because it is no fun trying to patch a rear wheel of an ebike. I got 200 miles, 6 months, no flats and no pumping to maintain pressure with a sealant.
If sealant won't work I suggest some run flat system like Tannis Armor + sealant. I have not used the Tannis Armor product so I cannot vouch for it. But I suggest it because, once again, it is no fun trying to patch a rear wheel of an ebike especially if you have kids waiting on you.
I have a RadRover 5 step thru and use the Tannus armor. It works pretty good but I have 120 TPI Surly Nate tires, that have worn down considerably. So recently just a small piece of glass managed to get through and give me a flat. I bought 30 TPI Origin8 Supercell street tires which are more puncture resistant because of the low TPI (thicker rubber).
I've had bad experiences with sealant. The problem is if the puncture is at the top of the tire when it's parked, the sealant doesn't touch it and what you get is a completely flat tire with a HUGE mess of sealant EVERYWHERE. The sealant also doesn't really work with inner tubes. It only really forms a seal with tubeless tires.
The problem you'll have though is once again the weird 22" custom tire size with the RadWagon. Tannus armor only comes in 20" or 24" size, so you'd have to cut it and that means having a gap in the armor. You'll also need a smaller inner tube because the armor takes up so much space, and I'm not sure a smaller tube in that size exists.
The best option is to buy a tire liner, probably 2. I've used the Mr. Tuffy liners and they work pretty good. I'm going to use that with the Tannus armor as soon as I can get my RadRover 5 working again (just died in the street and won't turn on)... 2 weeks and no response from customer support though. Not happy with their service so far.
