Should We Choose A Three-wheel Speed Skate Frame Or A Four-wheel Frame For Kids?

We often see some children using three-wheel speed skates and others using four-wheel skates. What exactly are the differences?

1. Taking 3×100 and 4×100 frame as examples – what distinguishes them?

The frame for a 3×100 frame is shorter, has a lower center of gravity, and is lighter than a 4×100 frame. This gives it an advantage at the starting line. For short-distance races, stride frequency is critical. Young children racing short distances can achieve higher frequencies with three wheels. However, the three-wheel setup sacrifices stability during gliding and cornering compared to four wheels. The longer frame of a 4×100 setup provides better cornering stability and grip, but its increased length makes crossover steps in turns more challenging. It is also heavier than a 3×100 setup, resulting in lower stride frequency. In terms of endurance, 4×100 significantly outperforms 3×100.

2. How does a 3×100 frame compare to a 4×90 frame?

In terms of top speed, the 3×100 setup achieves higher speeds than the 4×90. The center of gravity between these two configurations is similar, but the 4×90 offers greater stability. The 4×90 skate frame is slightly heavier than the 3×100 frame, contributing to its enhanced stability. Technical skaters are recommended to use 4×90, while frequency-focused skaters may prefer 3×100.

Our Opinion:
For youth learning speed skating, progression should follow this path: start with 3×90, advance to 4×90, then upgrade to 4×100, and eventually 4×110. Many parents prematurely switch their children to larger three-wheel setups at the same level, hoping to boost competition results through equipment. This is a misconception. While three-wheel setups may win through higher frequency, they often lead to an underdeveloped skating technique. Results matter, but speed skating is an endurance-based technical sport, not just a sprint. The focus should be on refining a skater's power application and technical movements during gliding, rather than chasing short-term gains by rushing the process.
