"7 gears are also no problem it does not give you less range only fewer increments."
That's interesting indeed. Which gear on the Radwagon 4 would replace the 22x34 on the Radwagon 3?

Why not spend $6 on a set of original spares from Rad Power Bikes?

As so many companies, the pencil pushers at Rad Power Bikes took away the 21 speeds (3x7) of the Radwagon 3 and skimped it down to 7 speeds (1x7). Based on your extreme situation, I would advise you to shop for a Radwagon 3 so that you can take advantage of low gearing and the geared hub motor. Frankly, a middrive would be even better in your situation. You can get a used Radwagon 3 for less than $1K, and for another $450, you can add a Bafang middrive. I have not seen one, but two Radwagon 3 who had the original hubmotor plus a middrive. That would solve your problems for sure.

sc00ter, I'm 63 years old. I own a 1960 Lambretta S2 and a 1963 Riverside, so basically a Lambretta S3. I've been walking the walk for many years.

Wkindred, thank you for that suggestion. I will try that route.

ScOOter, customers service is not my priority. I'm a lifelong cyclist and quite handy with bicycles. I don't need servicing, but I do need parts which I can't order anywhere else, sadly. To use your phrase, imagine you bought a car at a reasonable price and it breaks down on the way to work. For weeks you are trying to get the spare parts you need to fix the car but nobody responds to your inquiry. Eventually, someone tells you you "should have bought some other car" if service is your priority. That's what you said, and I won't take that the wrong way. Thank you for responding though; that's more than I can say about Rad Power Bikes so far.

I've read that Rad Power Bikes support is very good, but so far I don't see that. I need a few parts for my newly acquired 2017 Radwagon, contacted support using their form, but no response so far. I would understand that if it was a part for a vintage car that had to be special ordered from France or Italy, but Rad Power Bikes is right here in the United States of America, and unfortunately these parts can't be ordered from any other source because they don't publish what's used on their bikes.

If I need a part for my Bafang-powered bike, I can order that in a few minutes, even though that stuff is also made in China. Which, since I'm frustrated anyway, is the reason I would never buy a Radwagen V4. Imagine having to pay a ransom for 22" tires from a horder in Khazachstan because Rad Power Bikes decided to move to yet another size with the V5 or V6 and don't support "legacy" bikes anymore.

So here's my question: how long does it usually take to get a parts response from the good people at the Rad Power Bikes team?

Hi Y'all!

Rad Power Bikes has now Radwagon V4 out, the one with the tiny wheels.
But what's the evolution of the Radwagon?

I know that the 2018 model year brought the switch from a steel frame to aluminum. 2019 was pretty much unchanged. Along the way they eliminated 12 of the gears by going from 3x7=21 to 1x8.
2016 and 2017 were available in blue. As far as I know, all of those are called Version 3. So what about V1 and V2?
