HKM-3940051 3-in-1 Compact Baby Stroller PU Zipper Detailing Aluminum Alloy Frame Travel System with Car Seat and Bassinet
HKM-3940051
3-in-1 Travel System Stroller
The HKM-3940051 moves between a pushchair, an ISOFIX-compatible infant car seat, and a lie-flat bassinet on one 6063 aluminum chassis, so a single stroller covers your child from the first month through the toddler years. Each module clicks onto the frame through a quick-release hub that needs no tools, and the one-step fold collapses the system into a self-standing package held shut by an auto-lock latch. The five-point harness exceeds EN 1888, the three-panel UV50+ canopy blocks 98% of harmful UV rays, and the bassinet lies fully flat with a 3D mesh liner. Hand-stitched PU pull tabs run along the canopy edge and bassinet apron.
Key Features
Nine details that make the HKM-3940051 the urban parent’s choice.
True 3-in-1 Modularity
A pushchair seat, an infant carrier, and a lie-flat bassinet all mount to the same chassis, and each module seats on a quick-release hub that clicks without needing a tool to change mode.
6063 Aluminum Alloy Chassis
Aerospace-grade 6063 aluminum holds the frame rigid over curbs while keeping the carry weight low, and a corrosion-resistant anodized finish keeps its luster through daily use.
One-Step Compact Fold
A single motion collapses the system into a package that stands upright on its own, and an auto-lock latch keeps it folded while you lift it into a trunk or a hallway cupboard.
5-Point Safety Harness
Padded shoulder covers and a five-point harness hold shoulders, waist, and hips, and the backrest reclines through four discrete angles so your child can sit up or lie back.
UV50+ Extendable Canopy
A three-panel canopy extends forward to block 98% of harmful UV rays through the middle of the day, and a peek-a-boo mesh window lets you check on a sleeping child without lifting the hood.
ISOFIX Car Seat Base
The detachable infant carrier locks into a vehicle on ISOFIX-compatible connectors meeting FMVSS 213, and side-impact EPP foam wings spread crash energy away from the child.
Overnight-Approved Bassinet
The bassinet holds a fully flat sleeping surface with a breathable 3D mesh liner and high-sided cocoon walls, approved for overnight unsupervised rest so a trip away needs no separate travel cot.
PU Zipper Detailing
Hand-stitched polyurethane zipper pulls and leather-look trim run along the canopy edge and bassinet apron, with a wipe-clean surface that keeps the finish looking sharp.
One-Touch Rear Brake
A single foot press on the rear pedal secures the stroller instantly on an incline, so the chassis holds still while you lift your child in or out on a sloped driveway.
Overview
Engineered for the modern parent, built for the city.
The HKM-3940051 is a travel system built around one aluminum chassis and three modules that click onto it. The pushchair seat carries a five-point harness with padded shoulder covers and a backrest that reclines through four discrete angles, with dual front swivel wheels and suspension underneath. The detachable infant carrier locks into a vehicle on ISOFIX-compatible connectors meeting FMVSS 213, with side-impact EPP foam wings. The bassinet holds a fully flat surface with a breathable 3D mesh liner, approved for overnight unsupervised rest. The 6063 aluminum frame uses an aerospace-grade alloy with a corrosion-resistant anodized finish, and a single motion collapses the system into a self-standing package. Hand-stitched PU zipper pulls finish the canopy edge.
Three Modules, One Chassis
Pushchair, car seat, and bassinet.
All three modules mount to the same 6063 aluminum chassis, and each one seats on a quick-release hub that clicks into place without tools. The one-step fold drops the whole system into a self-standing package with the PU trim still fitted.
Full Specifications
Every figure below is shown in US customary units first, with metric units alongside it
Three Riding Stages
One chassis that follows your child through three stages.
The HKM-3940051 covers newborn to toddler without a second pushchair. Stage one is the bassinet: a fully flat surface with a breathable 3D mesh liner, approved for overnight unsupervised rest. Stage two is the infant carrier, which locks into a vehicle on ISOFIX-compatible connectors meeting FMVSS 213. Stage three is the pushchair seat, with a five-point harness, padded shoulder covers, and a backrest that reclines through four angles. The seat height adjusts through four gear positions, measured at 34 in (86.4 cm) from the ground at top setting. Every module clicks onto one hub without tools.
Daily Use & Care
A quick routine keeps the HKM-3940051 pristine.
Wipe the 6063 aluminum frame with a damp cloth after an outing. The anodized finish resists corrosion, so road salt and rain do not dull it.
Clean the PU zipper pulls and trim with a soft cloth to keep the hand-stitched finish intact. Avoid alcohol-based cleaners, which strip the leather-look coating.
Inspect the five-point harness buckles and the padded shoulder covers before each outing, looking for fraying where the webbing passes through the shoulder slots.
Wash the 3D mesh bassinet liner with mild soap and let it air dry completely before you fit it back, since a damp liner traps odour against the sleeping surface.
Lubricate the folding mechanism hinges and the quick-release hubs every three months. A dry hinge is the usual reason a fold starts to bind.
Check the ISOFIX connection points for crumbs before each car trip, since debris there stops the connectors seating on the vehicle anchors.
Clean the dual front swivel wheels and check the suspension springs for smooth travel. Hair and grit in the swivel are why a push feels heavy.
Store the stroller indoors and keep the fabric and PU trim out of prolonged direct sunlight. Sustained UV dries the PU coating and fades the canopy.

Why Choose the HKM-3940051
Nine reasons parents choose the HKM-3940051.
Three Modes, One Frame
The pushchair seat, the infant carrier, and the bassinet each click onto the same chassis without tools, so a single stroller covers the newborn months and the toddler years alike.
Built to Last for Years
Aerospace-grade 6063 aluminum with a corrosion-resistant anodized finish holds its shape and its luster through years of daily use on curbs, ramps, and wet pavement.
Folds in One Step
A single motion drops the system into a self-standing package, and the auto-lock latch keeps it shut so you can carry it one-handed onto a bus or into a hallway.
Safety Tested Harness
The five-point harness exceeds EN 1888, with padded shoulder covers and a multi-recline backrest that holds your child securely across four seating angles.
Sun Safe Canopy Protection
The three-panel UV50+ canopy blocks 98% of harmful UV rays through the middle of the day, and a peek-a-boo mesh window lets air move while you watch a sleeping child.
Ready for the Car
The infant carrier locks into a vehicle on ISOFIX-compatible connectors meeting FMVSS 213, and side-impact EPP foam wings spread crash energy away from the child.
Overnight Bassinet
The bassinet surface lies fully flat with a breathable 3D mesh liner and high-sided cocoon walls, so a night away needs no separate travel cot of any kind.
PU Leather-Look Detailing
Hand-stitched PU zipper pulls and leather-look trim run along the canopy edge and the bassinet apron, with a wipe-clean surface that stays smart in daily use.
Stops on a Dime Flat
One foot press on the rear pedal secures the stroller instantly on any incline, which matters on a sloped driveway while you lift a child in or out of the seat.
Controls & Indicators
What each control on the HKM-3940051 does.
Quick Hub
The click-to-lock fitting that joins any module to the chassis. Set the unit down, listen for the click, and lift it gently to confirm the lock has engaged
Rear Brake
A foot-activated pedal on the rear axle locks the wheels in one press, which is what holds the stroller on a slope while you load or unload a child
Fold Latch
The auto-lock catch that keeps the frame folded in transit. Press it firmly to release, and let it snap back into place before you carry the package
Harness Buckle
The five-point buckle with padded shoulder covers takes two deliberate movements to open, and the shoulder slots move as your child grows
Seat Release
A quick-release button separates the infant carrier from the frame, so the carrier can go straight from the stroller into the vehicle
Recline Lever
The lever on the back of the seat moves the backrest through four discrete angles, from an upright sitting position to a lie-back for naps
Frequently Asked Questions
Quick answers about the HKM-3940051.
What modes does the HKM-3940051 support?
Three. A pushchair seat for daily walks, a detachable infant carrier that locks into a vehicle, and a lie-flat bassinet. All three mount to the same chassis.
Is the bassinet approved for overnight sleep?
Yes. The surface lies fully flat with a breathable 3D mesh liner and high-sided cocoon walls, and it is approved for overnight unsupervised rest.
What frame material is used?
Aerospace-grade 6063 aluminum alloy with a corrosion-resistant anodized finish, which holds the frame rigid while keeping the carry weight low.
How does the car seat attach in a vehicle?
The carrier uses ISOFIX-compatible connectors meeting FMVSS 213, with side-impact EPP foam wings. Check your vehicle manual for the anchor positions.
What is the canopy coverage?
A three-panel UV50+ canopy that blocks 98% of harmful UV rays, with a peek-a-boo mesh window and a zip detailing run along the edge.
How compact is the fold?
A single motion collapses the system into a self-standing package held shut by an auto-lock latch, so it stands in a hallway instead of lying flat.
Quick Troubleshooting
Common HKM-3940051 issues and what to check first.
The stroller will not fold
Check that the seat is upright and the basket empty, then press the fold latch firmly to the end of its travel. A dry hinge is the usual cause, so lubricate the joints if it binds.
Wheels feel stiff or wobbly
Clear hair and grit from the swivel mechanism, add a drop of lubricant, and spin the wheel by hand. Check the hub sits flush against the axle.
The harness will not buckle
Look for a twist in either shoulder strap, which stops the two halves meeting, then clean the buckle recess with a dry cloth.
The car seat will not click in
Align the ISOFIX-compatible connectors with the vehicle anchors and press down firmly until you hear the click. Debris in the connector jaws is the usual cause.
The bassinet mesh is loose
Reattach the 3D mesh liner by securing every fastener around the frame, then pull the liner gently to confirm it sits flat.
It pulls to one side
Confirm both front swivel wheels turn freely, that the suspension sits evenly on both sides, and that the rear brake is fully released.

Before First Use
Run through these six checks before the first stroll.
Unfold the frame and confirm the auto-lock latch engages, then lift the handlebar gently to check the chassis is locked open.
Fit the wheels and spin each one by hand to confirm it turns freely and the hub sits flush against the axle.
Attach the pushchair seat, the car seat, or the bassinet and pull up on it to confirm the unit is fully seated on the hub.
Adjust the five-point harness to your child and check that the shoulder straps sit at or just above shoulder height with no twist.
Cycle the recline lever through all four angles and confirm the backrest holds at each position before you set off.
Extend the canopy and confirm it locks in each gear, then test the rear brake by pressing and releasing it with your foot.

Important Safety Notes
Read before the first HKM-3940051 stroll.
This HKM-3940051 is a wheeled child conveyance. Read the manual before the first stroll and practice folding and unfolding in an open area. Use the five-point harness whenever your child is in the seat, and do not leave a child unattended. Do not exceed the 33 lbs (15 kg) load rating. Engage the rear brake whenever you stop, and apply it before loading or unloading your child. Do not carry extra children or hang bags from the handlebar, since a loaded handle can tip the chassis backward. Keep away from stairs and open water.
