Best MIPS Bike Helmets for Tricycle Riders
Three helmets with integrated MIPS, compared on fit range, adjustment and visibility for upright trike riding.
Updated · 3 min read · 3 products evaluated
MIPS stands for Multi-directional Impact Protection System, a low-friction layer inside the helmet designed to reduce rotational forces in angled impacts. On a tricycle, falls are rarer than on a bicycle, but low-speed tip-overs on a curb or slope still happen, and the head can strike at an angle.
We compared three helmets that include MIPS: two versions of the Giro Fixture and the P2R A20 with a rear light. MIPS is only one part of a good helmet, so we also compare fit range, the adjustment system, ventilation and visibility.
Short answer
The Giro Fixture MIPS II is our best overall pick, with integrated MIPS, a Roc Loc Sport one-handed fit dial and a 54 to 61 cm range. The Giro Fixture MIPS is the same design in a different colorway, and the P2R A20 is the choice if you want a USB rear light and a named CPSC standard.

Giro Fixture MIPS II Helmet
Integrated MIPS with a one-handed fit dial and reflective details.
Best for
Riders who want a well-known MIPS helmet with a precise fit
Why we like it
The Giro Fixture MIPS II uses integrated MIPS and a construction that fuses the outer shell to the impact-absorbing foam, which makes it lighter. The Roc Loc Sport fit system offers one-handed operation with a 7 cm adjustment range, and reflective details return headlight beams at night. It is sold in a universal adult size for 54 to 61 cm heads.
Next to the P2R it has no light, but its fit system is easier to adjust on the move. Against the Giro Fixture MIPS, the maker details match, so choose by color and current stock. Measure your head to confirm it falls within 54 to 61 cm before ordering.

Same Design, Different Color2 of 3
Giro Fixture MIPS Helmet
The Fixture MIPS in matte black and grey with the same fit system.
Best for
Riders who want the Fixture in a darker colorway
Why we like it
The Giro Fixture MIPS has the same integrated MIPS, the same fused shell and foam construction and the same Roc Loc Sport dial with a 7 cm range as the MIPS II. Reflective details help at night, and the helmet is sold in a universal adult size for 54 to 61 cm.
Because the maker details match the MIPS II, the choice comes down to the colorway and whichever is easier to find. Against the P2R it has no rear light, so pair it with a separate light. Confirm your head circumference before choosing.

P2R A20 MIPS Helmet with Rear LED
MIPS plus a USB rear LED and 23 vents.
Best for
Dusk and commute riders who want built-in visibility
Why we like it
The P2R A20 combines MIPS with a named US CPSC 16 CFR Part 1203 standard, a removable USB-rechargeable rear LED with multiple modes, and 23 vents in a polycarbonate shell with an EPS liner. A rear adjustment system, adjustable straps and removable padding provide the fit.
Compared with the Giro helmets it adds a light and a named standard, but it gives no size numbers, so measure your head and check the size chart. The light is a rear light only, so a front light is still needed on a dark trike ride.

How We Chose These Mips Bike Helmets for Tricycle Riders
- MIPS integration
- Every helmet here includes MIPS. We checked whether it is integrated into the helmet and whether the maker describes what it is meant to do.
- Fit range and adjustment
- We compared stated head ranges and adjustment systems. A helmet that rocks on the head does not protect, so a well-tuned dial counted for a lot.
- Named standard
- We looked for a named safety standard such as CPSC. MIPS adds a layer, but it does not replace a certified impact standard.
- Visibility and cooling
- We considered rear lights, reflective details and vents. An upright trike rider is seen from behind at dusk, so these features matter.
What to Look for in a Mips Bike Helmets for Tricycle Riders
What MIPS does
MIPS adds a thin low-friction layer between the head and the helmet's foam, allowing a small rotation in angled impacts to reduce the force on the brain. It is designed for rotational forces, not a replacement for impact foam.
Choose it if you can, but treat fit and the safety standard as the first checks. A MIPS helmet that does not fit properly gives little protection.
Head range and dial
Helmets fit within a stated head circumference range in centimeters, and the dial adjusts within that range only. A universal size is convenient but only works if your head falls inside it.
Measure above the eyebrows with a soft tape and confirm the range. After fitting, the helmet should sit level and not rock when you shake your head.
Named safety standard
In the United States, bicycle helmets must meet the CPSC standard, 16 CFR Part 1203. A helmet that names the standard gives you something to verify.
Look for the standard in the product details and a sticker inside the helmet. MIPS is an addition to the standard, not a substitute for it.
Lights and reflective details
A helmet-mounted rear light sits high and is seen by drivers behind a low, wide trike. Reflective details return headlight beams without needing a battery.
If you ride near dusk, choose a rear LED, and remember to charge it. If you ride in daylight, reflective details may be enough.
How to Choose
By Fit System
| Situation | Our pick | Why |
|---|---|---|
| Adjust the fit on the move | Giro Fixture MIPS II | One-handed Roc Loc Sport, 7 cm range |
| Want a darker colorway | Giro Fixture MIPS | Same fit system in matte black and grey |
| Need a named standard and light | P2R A20 | CPSC 16 CFR 1203 plus USB rear LED |
| Head inside 54 to 61 cm | Giro Fixture MIPS II | Universal adult size covers that range |
Giro vs P2R
- Giro Fixture
- The Fixture uses integrated MIPS, a fused shell and foam, a 7 cm one-handed dial and reflective details. It has no light, so add a separate one.
- P2R A20
- The P2R adds a named CPSC standard, 23 vents and a USB rear LED with modes. It gives no size numbers and its light needs charging.
Most riders should default to the Giro for its fit system, and choose the P2R if a built-in rear light is the priority.
For Dusk Commuting Specifically
- Look for
- A rear LED, reflective details and a named safety standard, so you are visible from behind and protected in a fall.
- In this comparison
- The P2R A20 includes a USB rear LED and names CPSC 16 CFR Part 1203, while the Giro Fixture MIPS II offers reflective details only.
When to Spend More
- Spend more if
- You adjust your helmet often or share it between riders, where the Giro Fixture MIPS II's one-handed 7 cm dial earns its place.
- Save if
- You need MIPS and a rear light only; the P2R A20 bundles both without a separate light purchase.
Frequently Asked Questions
Does MIPS make a helmet safer on a tricycle?
MIPS is designed to reduce rotational forces in angled impacts, which can happen in a low-speed tip-over. It is an added layer rather than a guarantee, so a good fit and a named standard remain the first checks.
What head size do these helmets fit?
The Giro Fixture helmets are sold in a universal adult size for 54 to 61 cm. The P2R A20 does not give size numbers here, so measure your head and check its size chart. Wrap a soft tape above your eyebrows to measure.
Are the two Giro Fixture helmets different?
The maker details for the Fixture MIPS II and the Fixture MIPS match: integrated MIPS, the Roc Loc Sport dial and the same 54 to 61 cm range. Choose by color and availability, and confirm the details at purchase.
Do I still need a bike light with a helmet light?
Yes. The P2R rear LED helps drivers behind you see a low trike, but you still need a white front light and reflective gear. A trike is wide and low, so extra visibility helps.
When should I replace a MIPS helmet?
Replace it after any significant impact, even if no damage is visible, and consider replacing it every few years as foam and straps age. Check for cracks and frayed straps before each season.
Bottom Line
The Giro Fixture MIPS II is the best MIPS helmet here for most trike riders, thanks to integrated MIPS, a one-handed fit dial and a 54 to 61 cm range. Pick the Fixture MIPS for a darker colorway, or the P2R A20 for a named standard and USB rear light. Measure your head first.
