The Horacio brand has its roots deeply embedded in Australia, with all of its design processes taking place locally to ensure that each bicycle meets the high standards of Australian riders. The brand is named after our founder's family name, marking a personal touch and a nod to the legacy behind the brand. Our warehouse and office are currently located in the southern part of Brisbane.

Our 27.5 mountain bike is designed as an entry-level option, ideal for those new to mountain biking or seeking a versatile ride for various environments. It's perfectly suited for:

  • Leisurely Trail Rides: Enjoy nature trails and easy off-road paths without the technical challenges of advanced mountain biking.
  • Urban Commuting: Navigate through city streets and urban landscapes with ease, making it a great choice for daily commutes.
  • Park Paths: Glide through park surroundings, whether it's a gentle ride on paved paths or a more adventurous journey on gravel trails.
  • Coastal Routes: Experience the beauty of coastal paths and promenades, offering a scenic and tranquil ride.

This bike provides a comfortable and stable ride across a variety of settings, making it an excellent choice for recreational cyclists and those looking to enjoy the outdoors without tackling high-difficulty trails or extreme mountain biking maneuvers.

While the overall frame and key components of the 27.5 mountain bike remain consistent between the 2023 and 2024 models, ensuring the same quality and performance that riders have come to expect, there are a few notable upgrades in the 2024 model to enhance the cycling experience:

  • Quick-Release Wheels: The 2024 model features an upgraded quick-release mechanism for the wheels, making it easier and more convenient for riders to remove and attach the wheels for transportation or maintenance.
  • Aluminum Lock-On Grips: We've added aluminum lock-on grips to the 2024 model, offering increased durability and a more secure grip under all riding conditions. This upgrade ensures better control and comfort.
  • Hub Smoothness: The hub has been updated to operate more smoothly, enhancing the bike's overall efficiency and ride quality. This improvement means less resistance, more responsive acceleration, and a smoother ride experience.

Ensuring high quality and maintaining a strong reputation are fundamental to our ethos. We achieve this through meticulous selection of components and partnership with leading brands in the cycling industry. Specifically, we use highly reliable and well-regarded bicycle parts from brands known for their quality and performance, such as SR Suntour, Shimano,KMC, Velo, Kenda, Prowheel and Tektro.
