ER:ONE - Aero/Racing

The ER:ONE road frame represents a step forward in structural engineering. To achieve the combined goals of low weight, high stiffness, and reduced aerodynamic drag, every stage of development demanded precision. Each carbon ply is strategically oriented, resin ratios are optimized for strength-to-weight efficiency, and tube profiles are refined through repeated simulation and testing. From layup design to functional stress analysis, every parameter is verified and re-evaluated, ensuring a frame that balances efficiency, durability, and speed under real-world racing conditions.

After a not too easy build super happy with the bike, absolutely worth it

Overall, the frame quality, paint finish, and power transfer performance are exceptional. The bike feels fast, stiff, and very responsive on the road.

However, there were several hardware and component specification discrepancies upon delivery. I originally ordered a 10-30T cassette, but it arrived with a 10-36T cassette, and the headset spacers were different from the specification as well. Additionally, small accessories like the computer mount and valves were missing, and the saddle came as a Selle Italia instead of the listed SAMASSI 3D-printed saddle.

Fortunately, customer support (Fei) was very responsive and professional. They quickly resolved these issues by sending out the missing accessories and providing a fair partial refund to compensate for the specification changes.

Once dialed in, the ER:ONE is a fantastic performance bike for the price. Excellent frame quality and great post-purchase customer support!

Customer service was very responsive. They did not include the bike computer mount in my shipment which was disappointing. I reached out to the team that I talked to about my bike in China and they said that they would only include the computer in the next shipment of purchases which I did not like. I talked to the website customer service, and they said they would have the computer mount sent ASAP. I appreciated that response more and Greg from QPUSA sent it out. Overall , the bike is great and the builders said it is of good quality. Love the brand.

The bike is so fun to ride. Saddle has excellent comfort and the bike absolutely flies. I waited for a month or so to get a really good feel. Top notch components and packaging as well. Thank you!

Top Qualität. Schnelle Lieferung trotz Wunschlackierung. Jederzeit wieder. Nur schade das es bei Bestellung noch keinen 60er Laufradsatz gegeben hat

I am 5 rides in w the ER1. Sold my SL8 SWORKS and the experience has been really good. Customer service sent a missing cockpit bolt from US warehouse immediately. Customer service pre purchase was great. Bike took 15 days to arrive. Easy to finish the build. Bike is a rocket. Light. More comfortable than I thought. Conti tires. A great carbon rail saddle. Carbon spokes. Added a left side Quarq PM. Should be a great race bike. I'm 20 races into the season. Headed to Tulsa Tough in 2 weeks w the Quick. Mine is the Sram Force option.

Awesome bike! Light weight and fast. Can’t beat the price either - comparable big name brand would be almost twice as much.

Very happy with my purchase. Bike is great, stable, confortable, little road buz. The frame super aero and great build quality and finish. Quick Pro keeps attention to details. Bike came with premium Continental GP5000 tires which just makes the package complete. Personnel of the support is friendly and helpful.

Beautiful frame and the bike arrived in good cosmetic condition. Unfortunately, the components on the bike did not match what I ordered. I ordered 165mm crank arms, 50/37 chainrings, and a 10-30 cassette, but the bike arrived with 170mm cranks, 48/35 chainrings, and a 10-36 cassette.

The customer support team has also been very unhelpful and slow to respond, and so far they have not been able to provide a clear resolution to the issue. For a bike at this price point, I expected the build to match the order and any mistakes to be corrected quickly and professionally.
