Description

The ION Ti16 isn’t just a downsized frame—it’s a high-performance machine built for young riders who demand pro-level responsiveness.
Hand-certified aerospace-grade Gr5 Ti-6Al-4V Titanium (headtube, bottom bracket, and dropouts) and Gr9 Ti-3Al-2.5V Titanium (tubing), the Ti16 is precision engineered to deliver unmatched strength-to-weight ratio, lightning-fast handling, and a ride feel you won’t get from steel or alloy.

The geometry is tuned for performance: a 16” top tube paired with a 74.5° head tube angle keeps the bike snappy and aggressive, while the 10.6” chainstay balances stability with manoeuvrability. Every tube and weld is designed to reduce weight without sacrificing stiffness, giving younger riders a frame that reacts instantly to every pump, carve, and hop.

This is the same material and build quality trusted in aerospace and elite motor sports—scaled perfectly for the next generation of BMX progression.

Features
  • Aerospace grade titanium throughout. Hand certified Gr5 Ti-6Al-4V head tube, bottom bracket and dropouts, with Gr9 Ti-3Al-2.5V titanium tubing.
  • Around 1100g. Light enough to cut fatigue and lift agility, which gives a young rider more control in the air.
  • Snappy 16 inch geometry. A 16" top tube and 74.5° head tube angle keep it aggressive, while the 10.6" chainstay holds it steady.
  • Mid bottom bracket, 9.4" height. Set up for efficient acceleration, so every pump and pedal stroke goes into speed.
  • 14mm slotted dropouts. Integrated tensioners make chain alignment and adjustment easy to dial in.

  • Top tube: 16"
  • Chainstay: 10.6"

16 inch BMX sizing

A 16 inch bike suits a rider of about 96 to 122cm, usually 4 to 7 years old, on a 16 to 16.5 inch top tube. It is the size most kids learn to ride properly on.

160cm and up24"21.75 to 22"
160cm and up26"22 to 23"

Sizes overlap on purpose, so personal preference comes into it. At this wheel size the top tube barely changes the fit: go by height, and check they can stand over the bike flat footed.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark.

  • Between two wheel sizes? Go up. Kids grow into a bike far faster than they grow out of the fun.
  • They should be able to stand over the top tube with both feet flat on the ground.

Not sure? Send us their height and we will tell you what we would put them on.
