The carbon Tune Komm-Vor saddle
looks scary, as it’s unpadded, yet it was
quite comfortable, even on long rides,
but we’d guess it wouldn’t have been as
comfortable without the plush suspension.
The lack of a quick-release seatpost
saved weight, but the weight savings were
somewhat negated by the Allen key we had
to carry to always adjust the seatpost when
it came to descending steep drop sections.
Ultimately, that meant we started wearing
out the bolt after several rides.
The Magura MT8 dual-piston hydraulic
disc brakes were the perfect choice for this
price point of bike. With the huge 203mm
disc on the front and the 180mm on the
rear, this thing had serious stopping power.
Add to that the carbon levers, which added
even more of a cool factor.
Shifting was provided by the current
state-of-the-art Shimano XTR Di2
electronic shifters. These are incredibly
precise and quick. We used these on the
Stromer ST2 S, but the difference with the
Carbon Ultimate setup is a mechanical
lever instead of a touchpad that’s far more
accurate and easy to use for off-road
The Bosch CX mid-drive provides 350
watts of power and has the unique tiny
front sprocket. Stock bikes usually come
with an 18-tooth sprocket, so swapping
for a smaller sprocket in front by a tooth
or two makes a significant difference in
climbing torque. By the way, since this bike
is about exotic and light, the front sprocket
Every single choice of component on
this bike goes in to make it great—and
light. It corners beautifully. It handles jumps
without flinching, and the light weight
means you can throw it around and know
you’ll get it back. It truly becomes an
extension of you as a rider.
One interesting note is that the
European-spec version has carbon cranks
while the U.S. version comes with alloy.
There are two things you notice
on this bike right away. First, the
weight. It’s significant! We’ve ridden
a few electric bikes that weigh just
over 40 pounds, but they were more
like anemic city bikes without any
suspension. From the factory, the
fully built-up Haibike with top-flight
Fox suspension weighs in at a svelte
42 pounds, 8 ounces. By contrast,
the Haibike XDURO AllMtn Pro with
similar components weighs in at about
49 pounds, but that bike costs over
$10,000 less. If you’re doing math in
your head, that’s around $1500 per
pound of weight savings.
But it’s not just weight; making
carbon frames and wheels is a
painstaking process that can’t be
automated. It’s hand-built, and the
quality is palpable. The stiffness
imparted by the design and materials is
also rock solid.
It’s all in the details, and Haibike hasn’t missed one on this bike.
That little carbon flap keeps muck off the shock piston.
The stock Schwalbe Thunder Burt tires are incredibly light folders,
but they lack something in the bite department, even on fire roads.
