Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Giant - STP 20 FS Dirt Jumper Kids Bike in Teal

Season:2026

Brand:Giant

Code:9090025110

Dirt skills start here. With a lightweight aluminum frame that has a low stand-over height, a smooth-riding composite fork, and 20-inch wheels, the new STP 20 gives kids the confidence and maneuverability they need to start leaning into the turns, shifting their weight, and popping some air. It’s all the things that make riding fun.

Key Performance Factors:

  • FIT FOR YOUTH - The frame’s low stand-over height offers greater balance and stability with a lower center of gravity that’s ideal for riders 110-130cm tall. The 20-inch wheels and shorter 105mm cranks make for easier handling and smoother pedaling.

  • GREATER CONTROL - Youth-specific components including a Grit Core Lite saddle, smaller diameter handlebars, and hydraulic brakes with lighter modulation give STP 20 a smooth, controlled ride, helping young riders focus on building skills and gaining confidence.

  • PLAYFUL AGILITY - With a lightweight, durable ALUXX aluminum frame and Advanced-grade composite fork, the STP 20 is easy for young riders to maneuver. A shorter wheelbase and chainstays add a playful feel and make it easier to lift the front wheel while riding.
