Can raising the handlebar make bicycle speed faster? I tested it directly! - YouTube
GCN also conducted experiments on this topic....
This Shanghai Show Winspace T1600 new model also
has handlebars that are extremely raised.
Additionally, the fork also matches the recent trend....
Bicycles from various other small brands also have stacks gradually
rising in trend.
However, when raising the stack, rather than raising it with a steerer tube, making the head tube itself longer
is said to be better in terms of rigidity and cornering in many ways.
So they make the head tube as long and wide as possible and cut down the stem as much as possible
leaving only the minimum height...
The Morpheus bicycle made by a Dutch aero enthusiast also has this form.
It's almost an aero-focused bicycle lol
