YOUNGDO MTB Bike Saddle, 145 mm

A saddle that stays damp after a ride can make the next outing less appealing. This YOUNGDO model uses a waterproof PU surface and a hollow centre, with design features aimed at reducing rubbing and improving airflow.

It’s the MTB version, listed at 145 mm wide. The listing also names BMX and road bikes, but it doesn’t provide mounting dimensions to confirm fit for a particular bike.

Its focus is practical: a shaped saddle for riders who want padding, a cutout and a surface designed to handle wet conditions. Comfort will still depend on your riding position and what suits you personally.

Key specifications

The saddle has a 145 mm width and is described as the MTB model. Its materials include foam, thick artificial gel padding, a non-slip PU surface and stainless steel rails. The middle is hollow, while the front narrows to leave more room for thigh movement. These are design intentions, not a guarantee that the saddle will prevent soreness on every ride.

YOUNGDO describes the PU surface and stitching as waterproof and wear-resistant. That could be useful if the bike is left outdoors or caught in a shower, though the listing doesn’t explain how the saddle should be cared for over time. The hollow centre is intended to encourage airflow, on a warm ride, that gives air a route through the middle rather than leaving the surface fully covered.

Who it’s for

It suits you if you’re looking for a padded MTB-style saddle with a central cutout, and the 145 mm width seems appropriate for your riding position. The product is also presented for BMX and road use, but those labels alone don’t establish that it will fit every bike. The listing mentions other YOUNGDO styles—Trekking and City—so riders with a more upright position may prefer to compare those approaches rather than choose the MTB shape by default.

It won’t suit you if you need confirmed dimensions beyond the width, or want a specific fit recommendation based on your bike or riding posture. A width figure by itself can’t settle that decision. The product description also doesn’t give a saddle length or explain the rail dimensions, which limits how confidently you can assess fit before buying.

Everyday use

Picture a short ride home after rain: the PU surface is designed to resist water, while the narrow nose aims to reduce inner-thigh contact as you pedal. On a summer ride, the hollow centre is intended to let more air through. Those details may appeal if you want a more ventilated alternative to a solid, fully covered saddle, but they don’t establish how comfortable it will feel over longer distances.

The listing says the tools are included and installation is simple, but doesn’t identify the tools or give fitting instructions. Check that the saddle’s mounting arrangement matches your seatpost before relying on that claim. Padding may also feel different from a firmer, less cushioned saddle, so personal preference matters here.

Before you decide

Is this the MTB, Trekking or City version? The product information identifies this one as the MTB model, Trekking and City are mentioned as other available styles.

What is the listed width? It is 145 mm. No saddle length is provided, so width is only part of the fit picture.

Are installation tools included? The listing says the tools are complete, but doesn’t specify which tools come with it.

Final verdict

Choose this YOUNGDO saddle if you want the stated MTB shape, 145 mm width, padded construction and a hollow centre, and its waterproof PU surface is useful for your routine. It’s a less certain pick when exact bike fit is your priority: the product details don’t supply the full dimensions or a fit guide. If those missing measurements matter, compare them with your current saddle before deciding.
