The LiveLica Aerolite 4x90 is the classic four wheel speed frame in the LiveLica AI line. Four 90mm wheels sit low on a compact 10.86 inch platform, giving you the grounded, powerful feel that generations of speed skaters have raced on. It is the frame for track, short course and skaters who want stability and control alongside their speed.
Four 90mm wheels, the classic speed setup
The four by 90 layout is the setup speed skating grew up on, and it endures for good reason. Four wheels give you four points of contact with the ground, which means grip, stability and predictable handling when you load the skate hard through a corner or a start. It is a proven, confidence inspiring configuration that rewards good technique.
Low ride height, more control
At 90mm, the wheels keep you close to the ground. A lower centre of gravity translates into sharper control, quicker direction changes and a more direct connection between your push and the surface. That is why the 4x90 is a favourite for banked track, tight courses and any skating where handling matters as much as raw top speed.
Compact 10.86 inch platform
The 10.86 inch length keeps the frame short and agile, so it turns willingly and feels lively underfoot while still holding four wheels of stability. It is a nimble, responsive platform that suits technical skating and skaters who like to feel the skate move with them.
124 grams of 7075 T6
Machined from 7075 T6 aircraft grade aluminium, the Aerolite 4x90 weighs only 124 grams. Carrying four wheels at that weight takes a genuinely strong material, and the light build means less effort lost on every stride and a skate that feels quick to move.
Dual 165 and 195 mounting
The frame is drilled for both 165mm and 195mm mounting, so it fits the two common boot standards used across speed and fitness skates. Whichever your boots use, it bolts straight on, and it stays with you if you change boots down the line.
Tuned by AI led engineering
Like every Aerolite, the 4x90 is the product of AI led engineering. The frame geometry is handed to optimisation software that treats it as a puzzle of forces, keeping metal only along the paths that carry load and hollowing out the rest. The reward is a four wheel frame that holds its stiffness through a hard corner yet still tips the scales at just 124 grams.

Frequently asked questions
Why a four by 90 frame?
Four 90mm wheels keep you low and stable with four points of grip, which makes the skate controlled and predictable through corners and starts. It is the classic speed configuration, ideal for track and technical skating.
How does it compare to the other Aerolite frames?
The 4x90 is the low, stable, four wheel track setup. The Aerolite 3x125 is the big wheel triskate for top speed, the Aerolite Hi-Lo 3x110 plus 1x100 is a long road frame with forward pitch, and the Aerolite 90x3 is a short three wheel setup. Choose the 4x90 for control and a grounded, traditional feel.
What mounting do I need?
It is drilled for both 165mm and 195mm. Check your boot mounting before ordering, and message us if you are unsure.
What wheels and bearings does it take?
Four 90mm wheels and eight 608 bearings, two per wheel. Browse the wheels collection and speed bearings collection. Axles and spacers are included.
