Kosmos ハブレス折りたたみ式eバイク：Eバイクの未来を、無敵の価格で

The world of e-bikes has seen its fair share
of innovations, but one startup is taking things to the next level with a world-first
hubless foldable e-bike. Enter the Kosmos, a bold, futuristic bike that promises
to revolutionize the way we think about personal transportation. Designed to
combine the cutting-edge technology of a hubless wheel with the practicality
and affordability that most e-bikes lack, Kosmos aims to offer a smoother, quieter,
and more efficient ride than its competitors. What sets Kosmos apart from the growing sea of
e-bikes is its unique design. While hubless wheels have existed in concept for years, they’ve always
been impractical and too costly to mass-produce. The Kosmos Series, which includes two
models, the Kosmos F5 and Kosmos F5 Max, seeks to change that. Both models share
many features, but the F5 Max offers more power and higher-end tech for those who
want an even more premium experience. Both Kosmos models feature a hubless front wheel,
which is the centerpiece of the bike’s design. Kosmos claims that the hubless front wheel
improves aerodynamics, reduces weight, and lowers the center of gravity—all of which contribute
to better maneuverability and improved grip on corners. In fact, Kosmos boasts that this design
makes the bike feel lighter, though it still weighs in at 48.5 lbs , which is heavier than
other foldable e-bikes with traditional designs. But let’s talk about what’s under the hood. The
Kosmos F5 comes equipped with a 250W rear hub motor and a 5-speed internal gear system, while
the F5 Max upgrades to a 250W mid-motor with a 65Nm torque rating and a single-speed setup.
Despite the different motors, both models offer a range of 46-50 miles on a full charge, thanks to
their 36V 10.4Ah battery, which charges in just 4 hours. The fact that the battery is integrated
into the seatpost adds convenience, allowing it to be easily removed for charging and secured
with a locking device for extra peace of mind. Now, let’s address the elephant in the room—the
hubless wheel. While many skeptics argue that hubless wheels are still too complex and expensive
to be practical, Kosmos insists that they’ve figured out how to merge the pros of hubless
wheels with none of the cons. While the bike does feature a V-brake in the front and disc braking
in the rear, Kosmos claims these braking systems, combined with the pedal assist and torque sensor,
allow the bike to handle inclines with ease. In addition, they say the front hubless wheel
provides improved braking efficiency and safety—though it’s worth noting that these
claims are largely unverified at this point. The Kosmos F5 and F5 Max are also touted
as practical city bikes. They are foldable, making them easy to store or take on public
transport, and their lightweight design means you can bring them upstairs or stash them in
your car trunk without much hassle. With a starting MSRP of $3,500 for the F5 and $3,900 for
the F5 Max, it’s clear that Kosmos is positioning itself as a more affordable alternative to
many premium e-bikes on the market today. Early backers can get their hands on a Kosmos
for as little as $1,500 or $1,750 , though production isn’t set to begin until May
2025, with deliveries expected by July 2025. Kosmos isn’t just stopping at these two models.
They’re already eyeing future innovations, including a customizable digital display
that could replace the hubless tire entirely. While these bold claims are certainly ambitious,
the future of the Kosmos could very well shape the way we think about e-bikes—especially
if they can deliver on their promises.
