LiveLica now stocks a full range of Aerolite speed frames, six of them, and if you are staring at the list wondering whether you want three wheels or four, 90mm or 125mm, low and agile or long and fast, this guide is for you. The frame is the platform that turns your push into forward speed, so choosing the right one matters as much as your wheels or your boots. The good news is that all six Aerolite frames share the same core build, so the decision comes down to wheel setup and length rather than quality. Below we walk through every frame in the range, what each one is built for, and how to match one to your skating.
Everything here comes from the LiveLica product data for these frames, so the weights, lengths, wheel setups and mounting standards are the listed figures, not estimates. Every Aerolite is machined from 7075 T6 aircraft grade aluminium, shaped through AI led design that keeps material only where load actually flows, and every one ships with an Allen key, spacers and axles in the box. They all run standard 608 bearings. With that shared foundation in mind, let us look at what separates them.
The quick way to choose
Start with two questions. First, how big do you want your wheels, because wheel size sets your top speed and your ride height. Second, do you want three wheels or four, because that sets the balance between agility and stability. Small wheels and four of them keep you low, grippy and in control. Big wheels and three of them roll further and feel playful. Everything in the Aerolite range is a point on that map, from the short, nimble 90mm setups to the long, fast four by 110 race frame.
Every frame in the range at a glance, drawn to show how wheel count and diameter change from the short 90x3 up to the long four by 110 and the big wheel 3x125.
Aerolite 90x3, the short and agile flyweight
The 90x3 is the lightest frame in the range at just 114 grams, and it runs three 90mm wheels on a short 9.5 inch platform. That combination makes it a quick, agile, playful setup that accelerates fast and changes direction willingly. It is drilled for both 150mm and 165mm mounting, which is the widest mounting flexibility in the range, so it bolts onto a broad set of boots. If you want a light, nimble three wheel setup that balances top speed with agility and quick acceleration, the 90x3 is the flyweight of the family. Take a closer look at the Aerolite 90x3 for the full detail.
Aerolite 4x90, the low and stable classic
The 4x90 is the classic four wheel speed setup, four 90mm wheels on a compact 10.86 inch platform, weighing 124 grams. Four wheels at 90mm keep you low to the ground with four points of contact, which means grip, stability and predictable handling when you load the skate hard through a corner or a start. The low ride height gives you a sharper connection between your push and the surface, which is why this layout is a favourite for banked track, short course and any skating where handling matters as much as raw speed. It uses dual 165mm and 195mm mounting. If you value control and a grounded, traditional feel, the Aerolite 4x90 is your frame.
Aerolite 4x100, the do it all all rounder
The 4x100 sits right in the middle of the range and is the most versatile frame of the six. Four 100mm wheels on a 12.1 inch platform, at 148 grams, give you more rollout than a 90mm setup and more stability than a three wheel frame. The 100mm wheel is the middle ground of speed wheels, big enough to roll well and hold a good top speed, yet small enough to keep the skate agile and easy to control. If you train, tour and race across different sessions and want one frame that does a bit of everything, the Aerolite 4x100 is the sensible, do it all choice. It runs dual 165mm and 195mm mounting.
A rough map of the range. Move right for more rollout and top speed, move up for bigger wheels. The three wheel frames sit lighter and livelier, the four wheel frames sit more planted.
Aerolite 4x110, the full length race frame
The 4x110 is the longest and fastest four wheel frame in the range, four 110mm wheels on a 13.2 inch platform, at 159 grams. Four of the largest race wheels give you the long rollout of 110mm diameter with four points of contact, so the frame keeps carrying speed while staying planted under a full effort. The long wheelbase tracks dead straight and stays composed at race pace, which is exactly what you want when you commit to a hard, sustained push over a road race or a marathon. It runs dual 165mm and 195mm mounting. If you race competitively and want maximum four wheel speed and stability, the Aerolite 4x110 is the full out racing platform.
Aerolite 3x125, the big wheel triskate
The 3x125 carries three 125mm wheels, the largest diameter in common use, on a 12.6 inch platform, at 155 grams. Bigger wheels cover more ground per rotation, so each stride carries you further and holds speed for longer, which is why the largest wheels have become the choice for road, fitness and distance skating. Running three wheels rather than four keeps rolling resistance and weight down and makes the frame quicker to turn and more playful underfoot, while the big diameter still delivers a high top speed. It uses dual 165mm and 195mm mounting. If your priority is outright pace on a light, lively three wheel platform, the Aerolite 3x125 is built for it.
Aerolite Hi Lo, the long distance road frame
The Hi Lo frame is the long distance specialist, and its name describes how it works. Hi Lo means high at the back and low at the front. It runs three 110mm wheels with a single 100mm wheel up front on a long 12.9 inch platform, at 154 grams. Dropping the front wheel to 100mm while keeping the three rear wheels at 110mm sits you with a slight forward pitch, which puts your weight over the front of the skate. That sharpens acceleration, makes the skate feel more agile through a turn and gives a smooth, natural rolling motion, so you keep the sustained top speed of big 110mm wheels with a livelier feel than a flat setup. It uses the 195mm mounting standard. For road and marathon distance with a natural forward lean built in, the Aerolite Hi Lo is the frame.
A side view of the Hi Lo idea. The smaller front wheel lowers the toe of the frame, tilting your weight forward for sharper acceleration while the big rear wheels hold the speed.
Matching a frame to your skating
If you skate banked track or short technical courses and want the lowest, most controlled feel, the 4x90 is the natural home, with the 90x3 as a lighter, nimbler three wheel cousin. If you want one frame for everything from training to fitness to the odd road race, the 4x100 is the balanced all rounder. If you race road and marathon and want outright top speed, choose between the planted four by 110 and the lighter, livelier big wheel 3x125, and many serious skaters keep both and pick by course and conditions. If your focus is long distance with a lively, forward pitched feel, the Hi Lo is the specialist. Because every Aerolite is the same 7075 T6 build with the same box contents, you are only ever choosing a wheel setup and a length, not a level of quality.
Setting up whichever frame you choose
Once you have picked a frame, the rest of the setup is simple, because axles and spacers are included in every box. You will need the right wheels for your frame, and 608 bearings, two per wheel. Always confirm your boot mounting before you order, since the range uses 150mm, 165mm and 195mm patterns depending on the frame. If you are still weighing up wheel size and mounting in general terms rather than choosing a specific model, our companion guide on choosing an inline speed frame covers the underlying concepts, and this round up then helps you land on the exact Aerolite that fits.
Frequently asked questions
Three wheels or four wheels, which should I pick?
Four wheels give you more grip, stability and control, which suits track, short course and skaters who value handling. Three wheels are lighter and more playful and, with a big diameter like 125mm, still reach a high top speed, which suits road and distance skaters who want a lively feel. Neither is better in the abstract, it depends on your surface and your style.
What wheel size is fastest?
Bigger wheels roll further per rotation and hold top speed better, so the 125mm and 110mm frames carry the most speed. Smaller 90mm wheels keep you lower and more agile with quicker acceleration. The 100mm frame sits in between as a balanced choice.
Will these frames fit my boots?
Each frame lists its mounting. The 90x3 is drilled for 150mm and 165mm, the four wheel frames and the 3x125 use dual 165mm and 195mm, and the Hi Lo uses 195mm. Check your boot mounting before ordering and message the team if you are unsure.
What comes in the box?
Every Aerolite ships with an Allen key, spacers and axles, so you only need to add your wheels and 608 bearings to complete the setup.
Why are the frames so light?
They are machined from 7075 T6 aircraft grade aluminium and shaped by AI led design that removes material everywhere it is not carrying load, which is how a full four wheel race frame can weigh as little as 159 grams while staying stiff.
