Home Fitness Code F521 vs Y1: Which Walking Pad Should You Choose?
The Home Fitness Code F521 was a simple walking pad with a fixed 5% incline. The Home Fitness Code Y1 adds automatic incline up to 12% and speeds up to 10 km/h. The F521 is no longer sold on the Irish Home Fitness Code store, so this comparison explains the differences and the closest current alternatives.

Check price & availabilityIs the Home Fitness Code F521 still available?
No, not from the Irish store. The F521 was previously listed on the Irish Home Fitness Code store as “Treadmill F521, Speed 1-6KM/H, 5% Fixed Incline”. When we checked on 16 September 2026, that product page no longer loaded and the F521 did not appear in the current treadmill range. A UK third-party retailer also showed it as sold out.
If you already own an F521, nothing changes: it remains a basic walking pad for slow, steady desk walking. If you are buying today, compare the Y1 and the Z3 below.

The main differences explained
Incline: fixed or adjustable
The F521 had one fixed slope. The Y1 lets you move between flat and 12% from the remote, so you can warm up on the flat and add incline later in a session. The Z3 has a 5% manual incline, closer to how the F521 worked.
Speed: walking or light jogging
The F521 and Z3 top out at 6 km/h, which suits walking at a desk. The Y1 reaches 10 km/h, enough for light jogging, although it is not built for fast running.
Size and storage
The Y1 is 119 cm long, 15 cm high and 26 kg. The Z3 is 104 cm long, under 10 cm high and 13 kg, so it is much easier to slide under a sofa or move between rooms.
Noise
The retailer lists the Z3 below 30 dB and the Y1 below 50 dB. Floor type, speed and incline all affect how much noise reaches neighbours, so a mat is worth considering in apartments.
Incline walking feels harder than walking on the flat at the same speed. Build up gradually, and check with your GP first if you have a health condition, an injury or balance concerns.
Which model suits you?
Choose the Y1 if you
- Want to change the incline during a walk.
- Plan to walk briskly and jog lightly, up to 10 km/h.
- Need the higher 145 kg listed weight limit.
- Have space for a longer, heavier machine.
Choose the Z3 if you
- Liked the F521’s simple 5% incline and walking speeds.
- Want a slim, light machine that stores easily.
- Care about a low listed noise level.
- Want the option of a handrail version.
Delivery, returns and warranty in Ireland
- Delivery: the Irish store states free delivery, shipped from Germany, with 1 to 2 working days of processing and around 6 to 7 working days in transit.
- Returns: 30-day return and refund window, as stated by the retailer.
- Warranty: one year on both the Y1 and Z3, as stated by the retailer.
