MERACH Long Stride Cross Trainer Review: No Plug, Long Stride

Cross trainers are the machine people buy when their knees have opinions about running, and most of the sub-£600 ones make a poor case for themselves with a stride so short it feels like pedalling a shopping trolley. MERACH went after that specific complaint with a 47cm stride, then added a self-generating power system so the thing works in a garage with no socket. At £519.99 that is a genuinely interesting combination. It also carries one marketing claim that is plainly untrue, which is worth getting out of the way early.

The stride is the reason to buy it

Stride length is the single specification that determines whether a cross trainer feels like exercise or like a punishment. Cheap machines run 33cm to 40cm, which chops your gait into a short shuffle and gets uncomfortable inside ten minutes for anyone with normal length legs. MERACH quotes 47cm (18.5 inches) and specifies a suitable user height range of 1.5m to 2.2m, which is unusually broad.

The practical effect is that your hip and knee travel through something closer to a walking or jogging range, so you can hold a session for 40 minutes without your form degrading. That is the whole game with low-impact cardio: the machine only helps if you actually stay on it.

Self-generating power, and what it unlocks

No plug is a bigger deal than it sounds. Home cardio equipment usually ends up in the one room with a spare socket, which is rarely the room you want it in. A self-generating machine powers its own console and resistance system from your pedalling, so a garage, a shed, a conservatory or a garden room all become viable. There are no batteries to replace either.

The trade-off is minor: the display comes alive when you start moving rather than sitting there ready, and it goes dark shortly after you stop. Anyone used to a mains machine will notice for about two sessions and then forget about it.

Two claims that do not survive scrutiny

MERACH states an operating noise level below 20 dB. For scale, 20 dB is roughly leaves rustling, and quieter than a whisper at a metre. No machine carrying a moving human being hits that, and repeating the number would be doing you a disservice. The honest version is that magnetic resistance with no drive belt and sealed bearings is genuinely quiet, quiet enough to run with the television on at normal volume, which is what most people actually want to know.

The second claim is a stated 30% increase in fat-burning efficiency from the multi-grip design. There is no published basis for that figure and the mechanism does not really exist as described. Using the handles does recruit more upper body, which raises total energy expenditure a bit; it does not make fat oxidation 30% more efficient.

What the research does support is the low-impact case. Elliptical exercise produces smaller vertical pedal reaction forces and lower loading rates than running, at the cost of greater hip flexor and knee extensor moments (joint loading during elliptical exercise), and comparisons of treadmill, elliptical and stepper work show they can be programmed to similar physiological demands (physiological responses across treadmill, elliptical and stepper). Use it consistently and it will get you to the NHS target of 150 minutes of moderate activity a week without the pounding.

Where it falls short

The 8kg flywheel is the honest weakness. A longer stride wants more rotating mass to smooth out the dead spots at the ends of the arc, and 8kg is modest for a 47cm machine; expect the motion to be good rather than the glassy smoothness of a commercial elliptical with a 20kg wheel. Adjusting resistance at a flywheel knob rather than console buttons is the other small annoyance, since it interrupts an interval rather than letting you change on the fly.

Connectivity is the clearest gap. There is an LCD showing time, distance, calories and speed, and that is the whole story: no listed Bluetooth, no Zwift, no Kinomap. If virtual routes are what keeps you on a machine, this is the wrong one and our best cross trainer UK guide covers connected alternatives. If you would rather have a podcast and a stride that fits your legs, the trade is a good one.

Value

Five hundred and twenty pounds buys a lot of cross trainer here. The comparable machines in our best cross trainer guide at this price mostly run shorter strides, lower weight capacities and mains power, and MERACH's own track record on Amazon UK is solid across its treadmill and rower lines. Against a Reebok GX50 or a JLL CT300, the MERACH wins on stride and weight capacity, and loses on brand familiarity. If you are still deciding between machine types entirely, our rowing machine versus cross trainer comparison is the place to start.
