The cheapest American tube here, and it publishes two different weights
Bell 26" × 1.75-2.25, Schrader 35 mm (1.38 in)
A mold-cured 26-inch Schrader tube for cruiser and mountain bikes, covering 1.75 to 2.25 inch tires.
What you are getting
A 26” × 1.75-2.25 Schrader tube with a 35 mm (1.38 in) valve, mold-cured rubber, for cruiser and mountain bikes. $7.99 — the cheapest tube on this page.
It publishes two different weights
Bullet four ends with “210 g (7.4 oz)”. The shipping record for this listing says 136 g (4.8 oz).
Both come from the same page, and Bell does not say which is which. The likeliest reading is that 136 g (4.8 oz) is the tube and 210 g (7.4 oz) is the tube in its box — but it could as easily be the other way round, and 74 g (2.6 oz) on a tube is the difference between a light tube and a middleweight one.
The Continental road tube on this page handles the same problem properly: “about 100 g (3.5 oz) each per Continental’s catalog”, with the source named.
Thirty-five millimeters of Schrader, and the garage argument
“Standard 35 mm (1.38 in) Schrader valve with cap; inflates at any gas station or standard pump.”
That is the real case for Schrader and it is worth stating plainly: the valve on this tube is the same fitting as a car tire, so a petrol-station airline works. Nothing with a Presta valve does, without an adapter that lives in a drawer.
Thirty-five millimeters is three more than the Ultraverse 26-inch tube’s 32 mm (1.26 in) and plenty for a box-section 26-inch rim.
Its width range is the widest here, by a whisker
1.75 to 2.25 inches, against 1.75–2.125 for both the Ultraverse and Slime tubes on this page. In ETRTO terms that is roughly 45-559 to 57-559 at the bottom and a little beyond at the top — but Bell never publishes an ETRTO pair, so “roughly” is as close as this listing allows.
The buying advice on this page is to read the ETRTO off the sidewall. On this product you will have to convert it yourself.
What “mold-cured” is doing in the first bullet
“Durable mold-cured rubber — consistent sidewall helps prevent high-pressure blowouts.”
Mold curing is how a tube gets a uniform wall thickness, and a uniform wall is what stops a thin spot ballooning. It is the same property Continental describes as “seamless construction, with a mold-cured vulcanization”. Here it is stated once and not quantified.
What is not published
No ETRTO, no wall thickness, no pressure range, and no resolution of the 136 g / 210 g gap. The fifth bullet is fitting instructions. At $7.99 the listing is thin and the price is honest about it.
