Frequently Asked Questions
Everything you need to know about the VORTEX 20"
What age is the VORTEX 20" suitable for?
The VORTEX 20" is perfect for young riders aged 5–8 years old, or riders with a height between 107–130cm (3'6" to 4'3"). The 20" wheel size offers the right balance of stability and maneuverability for early adventures.
Is this bike easy to assemble?
Yes! The VORTEX 20" comes 85% pre-assembled. You'll just need to install the front wheel, pedals, handlebar, and seat. Clear instructions are included, and most parents can complete assembly in 30–45 minutes with basic tools.
Why choose mechanical disc brakes over V-brakes?
TEKTRO mechanical disc brakes provide consistent stopping power in all weather conditions. They require less hand strength than V-brakes, making them perfect for younger riders, and offer better modulation for safer, more controlled stops.
What warranty comes with the VORTEX 20"?
We offer comprehensive warranty coverage: Lifetime warranty on the frame, 2-year warranty on SHIMANO components and wheelsets, and 12-month warranty on all other non-consumable components. Consumable items like tires, tubes, brake pads, chains, and grips are not covered. For full details, visit horaciobikes.com.au/pages/warranty.
How long will this bike last my child?
The VORTEX 20" is built with a durable 6061 aluminum frame and quality components to grow with your child. With adjustable seat and handlebar positions, it typically fits kids for 2–3 years as they grow. The 20" size is a great first step into real mountain biking.
What's included with the bike?
Your VORTEX 20" comes with everything needed to start riding: the bike itself with a convenient kickstand already installed. You'll need to purchase a helmet separately (always required for safety), and you might want to add accessories like a water bottle holder, bell, or lights.
