Best 20 x 1.75 Bicycle Inner Tubes for Tricycles
Five Schrader tubes that start at 1.75 and run up to 2.125, ranked for a 20 inch trike wheel.
Updated · 4 min read · 5 products evaluated
Twenty inch wheels turn up on compact adult trikes, folding trikes and many front positions, and 20 x 1.75 is the lean, fast end of that range. The 406 in the ETRTO code is the bead seat diameter in millimeters, which is what separates a true 20 inch rim from the 16, 24 and 26 inch sizes that sit nearby.
Every tube here covers 1.75 and extends upward to 2.125, so the choice is less about whether it fits and more about wall thickness, valve length and how many tubes come in the pack. Those details decide how easy a roadside flat is to fix on a wheel that already carries a rider.
Short answer
The DBXIIART two-pack is the best overall pick for a loaded trike wheel because it states a 1.1mm wall that is 15 percent thicker than other brands. The PAKCHEF set suits riders who want a standard 32mm valve, and the Hydencamm pack adds levers. The Goodyear and YunSCM single tubes cost less per swap but offer fewer extras.

Our Picks
Best Overall1 of 5
DBXIIART 20 x 1.75/2.125 (47/57-406) Heavy Duty Tubes, 2 PCS
A stated 1.1mm wall, 15 percent thicker than other brands, suits a trike wheel that carries steady load.
Best for
Loaded 20 inch trike wheels
Why we like it
This two-pack is marked 47/57-406 for tires from 1.75 to 2.125 and uses butyl rubber with a 1.1mm wall. The maker also states each tube went through a 24 hour air leakage test, which speaks to the airtightness that matters when a spare sits in a basket for weeks.
It is the thickest-wall option here, so it gives up some of the light weight of the YunSCM tube in exchange for puncture margin. The 35mm Schrader valve clears most standard rims, though one line in its copy mentions 26 inch wheels, so confirm the 20 inch fit on the pack before opening it.

Best With a Standard 32mm Valve2 of 5
PAKCHEF Heavy Duty 20 x 1.75-2.125 Inner Tube, Set of 2
A two-pack with the common 32mm Schrader valve and a heavy duty butyl build.
Best for
Standard rims with short valve holes
Why we like it
The PAKCHEF set covers 20 x 1.75, 1.95, 2.10 and 2.125 with a 32mm Schrader valve. That shorter stem suits rims and fender stays with little clearance, and the tubes are aimed at kids mountain bikes, BMX and cruiser wheels, which share the same 20 inch bead seat as many trike wheels.
Compared with the DBXIIART it is plainer on wall claims and shorter on valve length. It earns its place for riders who need the shorter stem, and it comes with two tubes rather than the single YunSCM or Goodyear.
Key specs
| Wheel size | 20 x 1.75, 1.95, 2.10, 2.125 |
|---|---|
| Features | 32mm Schrader valve, heavy duty butyl, set of 2 |

Best Kit With Levers3 of 5
Hydencamm 20 x 1.75-2.125 Bike Tubes with Levers, 2 Pack
Two tubes with 35mm Schrader valves, a 16 percent thicker wall and two upgraded levers make a complete roadside kit.
Best for
First-time tube swappers
Why we like it
The Hydencamm pack has two 35mm Schrader tubes for 20 x 1.75, 1.95, 2.10 and 2.125, plus two thicker tire levers. It is aimed at kids, BMX, cruiser and mountain bike wheels, and the maker advises checking the tire size before buying, which is good practice on a trike too.
Against the PAKCHEF it trades a shorter valve for a longer one and adds levers, which makes a tight 20 inch bead easier to seat. Its wall is stated as 16 percent thicker than standard tubes, but the DBXIIART still has the thicker 1.1mm figure for heavy loads.
Key specs
| Wheel size | 20 x 1.75, 1.95, 2.10, 2.125 |
|---|---|
| Features | 35mm Schrader valve, two tire levers, wall 16% thicker, butyl rubber |
Specs can change between model years; confirm the exact version before buying.
Strengths
- Levers in the box
- Two tubes per pack
- Longer 35mm valve reach
- Butyl rubber build
Limitations
- Wall claim is relative, no millimeter figure
- 35mm valve can foul fender stays
- Title also mentions 1.95
Consider it if
- Complete roadside kit
- Deeper rims
Skip it if
- Heavy-load wheels needing a thick wall
Best Single Spare4 of 5
YunSCM 20 x 1.75/1.95/2.125 Schrader Valve Tube
A single 32mm Schrader tube naming six 20 inch widths, for a spare that stays out of the way.
Best for
One spare tucked into a basket
Why we like it
This single tube names 20 x 1.75, 1.90, 1.95, 2.0, 2.10 and 2.125 and uses a regular 32mm Schrader valve. Naming six widths makes it the most flexible tube here for mixed 20 inch wheels.
Compared with the two-packs it costs less per swap but only covers one flat, and it has no wall claim or levers. It is a sensible spare for a trike that already has fresh tires.
Key specs
| Wheel size | 20 x 1.75, 1.90, 1.95, 2.0, 2.10, 2.125 |
|---|---|

Best Known Brand5 of 5
Goodyear 20 x 1.75-2.125 Schrader Valve Tube
A brand-name tube made for 20 x 1-3/4 to 2-1/8 tires with a Schrader valve.
Best for
Riders who prefer a major tire brand
Why we like it
The Goodyear tube is sized for 20 x 1-3/4 to 2-1/8 inch tires, the older fractional way of writing the same range, and has a Schrader valve. The maker highlights rubber construction aimed at punctures and wear and says the design eases mounting.
It is a single tube with fewer concrete specs than the DBXIIART or PAKCHEF, with no ETRTO code, wall figure or valve length. It suits a rider who values the brand name and will match the tire size themselves.
Key specs
| Wheel size | 20 x 1-3/4 to 2-1/8 |
|---|---|
| Features | Schrader valve, single tube |
Specs can change between model years; confirm the exact version before buying.
Strengths
- Major tire brand
- Fractional size matches old tires
- Schrader valve
- Mount-friendly design
Limitations
- No ETRTO code
- No valve length given
- Single tube only
Consider it if
- Older tires marked in fractions
- Brand-minded riders
Skip it if
- Riders wanting exact valve length

How We Chose These 20 X 1.75 Bicycle Inner Tubes for Tricycles
- 1.75 in the range
- A tube had to name 20 x 1.75 or a range that begins at or below it. We also noted which ones state an ETRTO 406 code for clarity.
- Valve length
- A 32mm valve clears tight rims, while a 35mm valve reaches deeper rims. We marked which option fits which situation.
- Wall thickness claims
- Only one tube states a measured wall. We gave extra weight to stated numbers over general toughness language.
- Pack contents
- Two tubes or a tube with levers covers more situations than a single. We ranked complete kits above single spares at a similar fit.
What to Look for in a 20 X 1.75 Bicycle Inner Tubes for Tricycles
Decoding 20 x 1.75
The 20 is the approximate outer diameter in inches, the 1.75 is the tire width, and the ETRTO 406 is the bead seat diameter in millimeters. A 47-406 tire is the metric twin of a 1.75 tire.
Read your sidewall before ordering, because 20 inch tires also come in a 451 bead seat that will not take a 406 tube. Photograph the marking if you shop away from the bike.
Where 1.75 falls in the band
A 1.75 to 2.125 tube is designed to stretch around a tire from lean to wide, with 1.75 at the narrow end where it is stretched the least.
That makes 1.75 a comfortable fit rather than a stretched one, which keeps the wall thicker in practice. You gain flexibility if you later move to a wider tire.
32mm versus 35mm valve
Both are Schrader valves, but a 35mm stem reaches further through a deeper rim, while 32mm is easier on a small fold hinge or fender stay.
Hold a ruler against the rim hole depth and any fender stay before buying. A stem that barely clears the hole is harder to pump and can tear at the base.
Wall and rim protection
A thicker wall resists small punctures and holds air longer, which matters on a trike wheel that supports steady load without leaning away from road debris.
Check the rim strip inside the wheel for gaps over spoke holes, because even a thick tube can wear through. Look for the DBXIIART style stated wall figure when you want a number to compare.
How to Choose
By Wheel Load
| Situation | Our pick | Why |
|---|---|---|
| Loaded trike wheel with cargo | DBXIIART 20 x 1.75/2.125 (47/57-406) Heavy Duty Tubes, 2 PCS | Stated 1.1mm wall resists punctures under load |
| Light errands on paved paths | YunSCM 20 x 1.75/1.95/2.125 Schrader Valve Tube | Single spare covers a flat without added bulk |
| Tight valve clearance | PAKCHEF Heavy Duty 20 x 1.75-2.125 Inner Tube, Set of 2 | Short 32mm valve clears fender stays |
| First-time fitter | Hydencamm 20 x 1.75-2.125 Bike Tubes with Levers, 2 Pack | Two levers included for a tight 20 inch bead |
Thick Wall vs Standard Tube
- Thick wall
- The DBXIIART tube states a 1.1mm wall, which resists thorns and holds air through long storage. The trade is slightly more weight and a firmer bead to seat on a small rim.
- Standard tube
- The PAKCHEF, Hydencamm, YunSCM and Goodyear tubes are conventional butyl builds. They seat easily and weigh less, which suits light paved use, but they give less margin on rough surfaces.
Most trike owners should default to a standard tube unless their wheels carry cargo or ride rough paths.
For Folding Trike Wheels Specifically
- Look for
- A short valve that clears a hinge or fender stay, a tube small enough to pack in a bag, and a width band starting at 1.75.
- In this comparison
- The PAKCHEF 32mm valve and the single YunSCM tube both pack small. Choose the Hydencamm set if you also want levers in the same bag.
When to Spend More
- Spend more if
- Your wheels carry cargo or face rough surfaces. The DBXIIART two-pack gives the only stated wall figure, and thicker tubes cost slightly more than the standard options.
- Save if
- You ride short paved loops. The YunSCM single tube or the Goodyear tube meets a basic spare need, and a two-pack would sit unused in the basket.
Frequently Asked Questions
Does a 1.75 tire fit a 20 x 1.75-2.125 tube?
Yes. All five tubes cover 1.75 and extend to 2.125, so a true 1.75 tire is at the narrow end. The tube stretches little, which keeps the wall thicker and helps it hold air.
What does 47-406 mean?
It is the ETRTO code for tire width in millimeters, then bead seat diameter. 47 millimeters is roughly 1.75 inches, and 406 is a true 20 inch rim, so it describes your tire in metric.
Can I use these on a 24 inch trike wheel?
No. A 24 inch wheel has a 507 millimeter bead seat, and a 406 tube is too small. Match the size on the sidewall and buy a tube for that rim instead.
Do I need levers to fit a tube?
A 20 inch bead is often tight, so levers help, and the Hydencamm pack includes two. A flat spoon style lever is gentler on aluminum rims than a screwdriver.
How do I check a new tube before installing?
Add a little air and look for an even shape and no bunching. Some makers suggest dipping it in water to find bubbles, and the valve position should sit straight in the rim hole.
Bottom Line
For a loaded 20 inch trike wheel, the DBXIIART two-pack is the strongest pick thanks to its stated 1.1mm wall. The PAKCHEF suits short-valve clearance, the Hydencamm adds levers, and the YunSCM or Goodyear single tubes make simple spares. Read the sidewall before ordering.
