20 x 4 tube for fat tire DjEbike. Looking in Toronto.

[SDB]

Just got a flat tire on a fat tire ebike. Need a 20 x 4 tube. Tried Emmo as it was right by where the flat happened. Phoned another spot and it doesn't seem to be an easy size to find. Anyone happen to know where i can find one of these in downtown Toronto?

T.I.A.

Saw those but when reading reviews on the Canadian Amazon site , I saw this.

the product is advertises as 20X4 for fat tire. The tube is actually 20X4.0/4.9.
My wheel is 20X4.0 but tire requires tube 20X3.75/4.00.
Infos on product to be more precise on the size issue.
I asked for replacement for right appropriate size...


But then, this review.

Bought two of these to fit our Rad Power Mini Step thru E bikes. With 20x 4.25 tires. Quick delivery!


If all else fails, I will have to give this one a go.

I have used those tubes(20x4) and also 20x4.25 tubes on my fat tire bike that says 20x4 on the tire with no issues.

The inner tube that actually came with the tire was 20x4.20 for whatever reason.
