Amazing Bike!

I have only put 80 or so miles on the bike but it has been great so far. No issues. I was nervous ordering from china as I live in the US but everything went well. It took a long time to arrive but it was worth the wait. The wheeltop shifting has worked good. It's worth the money for sure. A little difficult to set up but it's been great and had no issues since! The bike isn't light compared to my carbon US bikes but for the price it's more than I could ask for. I got the green color with no decals and it looks really good! I honestly suprised how amazing the bike is. I'd definetely recommend buying this bike.

good bike!!!!!

Много добър велосипед на прилична цена! Пристигна добре опакован, сглобяването беше бързо. Единственото нещо, което не беше ОК е веригата. Имаше прещракване на някое звено, когато минаваше приз едната зъбчатка на задния дерайльор, но го оправих.

Road Bike Twitter R15 Pro — Honest Review After 500km

It arrived in a non-branded box. Initially, I was expecting a “Twitter”-branded box like the ones seen in YouTube unboxing videos. I later learned that some sellers ship in plain packaging to save on shipping costs — something I didn’t know beforehand. Despite that, I took the risk and was convinced it’s a genuine Twitter bike with valid warranty.

Packaging & Assembly:

The bike was very well packaged, with plenty of foam and protective materials to prevent scratches or damage during shipping.
Assembly was straightforward, and all necessary tools were included in the box. The only thing I’d recommend having on hand is high-quality grease — especially for areas with metal-to-metal contact.

Performance & Components:

The WheelTop derailleur came pre-installed by the manufacturer. To my surprise, it was perfectly tuned right out of the box — no adjustments needed, unlike what some others have experienced.

Torque specs weren’t listed on the website, but the customer support team kindly provided them via email. Sharing here in case it helps someone else:
• Bottom Bracket (Threaded): 35–50 Nm
• Crank Bolts: 35–50 Nm
• Stem Bolts: 5–6 Nm
• Seatpost Clamp: 4–5 Nm
• Derailleur Hanger Bolts: 5 Nm
• Disc Rotor Bolts: 6 Nm
• Brake Caliper Bolts: 6–8 Nm

Final Thoughts:

I’ve now ridden the bike for around 500 km, and so far, everything has performed flawlessly. All components matched the specifications listed by the seller.

Would I recommend this brand and model?
Absolutely — Yes.
Great value, great support, and a smooth riding experience.
