Wonderful speed machine! The bike is very well built, rit rides super smooth on the Texas' roads I usually tour. I'm very pleased with the quality and the color I picked, Chameleon White. I can feel the difference in speed/watts with my old Cevelo S5, I have gained a few miles/hour with the same power output! I'm ready to try it on the hills as the bike is lighter than my S5 and about the same weight as my Willier Zero SLR.
This a game changer super bike, I am not coming back to big name (and very expensive) bikes...

Awesome

Its solid stiff for me (80kg). And the comfort comes from the seat post design. It just want to go fast.

Wheels are lightweight and I like there style and at that price point you can't fine no were. Thanks

Frame Bundle came excellent packaged some other companies could learn from it
The paint job looks looks very well done inside of the frame looks very clean and smooth to me I don't see a difference to a brand name which costs double or more
Customer Service is responsive and will answer your questions you might have

After riding approximately 500 km, I can finally share my review of my new Winspace SLC 5 equipped with Ultegra Di2 and Hyper 5 wheels (40 mm).

The first thing you notice is simply how good the bike looks. It’s genuinely beautiful, and in the Mirage Chameleon colorway it’s especially striking. The second thing that stands out is the weight—or rather, the lack of it. With Assioma power meter pedals, in size S, my home scale shows around 7 kg. And this lightness is definitely noticeable on the road.

Climbing feels effortless, and riding out of the saddle is an absolute pleasure. I ride mostly on local roads of mixed quality—there are more potholes, cracks, and rough asphalt than smooth, freshly paved sections. And what surprised me the most is how incredibly well the bike absorbs all those imperfections. You barely feel the bumps or cracks; the rear end is exceptionally compliant and comfortable. The front end, on the other hand, is a bit stiffer, partly due to the solid handlebar setup. In short: business at the front, fun at the back.

Because of this comfort, your internal sense of speed needs serious recalibration. You look at the computer and notice you’re going 5–10 km/h faster than what the feeling suggests. At my 60 kg, the bottom bracket also feels stiff and efficient—power transfer is immediate. When accelerating, by the time you’re halfway through the pedal stroke, the bike is already surging forward.

The geometry strikes a great balance: stable, responsive, and with the shorter chainstays, it even feels playful. Build quality appears top-tier, absolutely on the level of major, well-known brands.

Cons?
The paint is a bit sensitive to scratches—it almost feels like if you look at it wrong, it’ll show a mark on the otherwise beautiful finish. Personally, I’m also not a big fan of the large, bold logo on the downtube. The brand name is written twice—once again on the fork—which I find a bit unnecessary.

Recommendation:
I fully recommend this bike to anyone looking for a true all-rounder—something you can comfortably take on a relaxed coffee ride, but also race with, and everything in between. The Winspace SLC 5 delivers on all fronts.

Awesome bike for its price.

Si comporta come una bici da strada tiene la velocità benissimo ed è molto scattante ,per ora posso solo dare feedback positivi 🚀

Great experience with Winspace!

From the initial questions to placing the order, the communication was clear, fast, and very professional. The team guided me through shipping, import, and delivery to the EU, and everything matched exactly what was explained in advance.

Ordering was straightforward, and the delivery process was well handled, even for an international purchase. Overall, a very smooth and reassuring experience — I’m really happy with both the service and the bike.

Highly recommended.

Everything looks great. Really carefully packaged. Haven't ridden it yet though due to Swedish winter.

Love the color and everything about the frame soon I will have finished with the build and I will be taking a picture. thanks to WINSPACE . EROD

Everything as it should be <3

Very happy with this bike. The Winspace T1550 Gen 2 delivers an excellent ride quality and feels truly high-end. It’s stiff where it needs to be, comfortable on longer rides, and overall a joy to ride.
Shipping to Belgium was impressively fast — I received the bike in less than three weeks from the China warehouse.
Customer service is also a big plus. I had a few questions and always received quick, clear, and helpful responses.
All in all, a great bike with fast delivery and excellent support. Highly recommended.

Ahoj, maximální spokojenost , lakování předčilo ma očekávání , na živo je opravdu nádherný. Balení super. Komunikace lepší než s Evropskými shopy. Doprava také bez problému . Díky

Great overall bike! Even came with flat pedals, a bike bag with accessories and a small portable toolkit.

Only negative things that come up after the first short test ride are a slipping seat post (should be fixed easily with some carbon paste) and the stickers on the front headtube. (When turning the handlebar 90 deg it bumps into the headset, which usually does not happen in normal riding conditions)
