Sciu Bikes is a new German bicycle brand operating out of Hamburg, launched at the back end of January with two bikes; the Sciu Aspen Enduro and the Sciu Juniper Gravel. Gjovalin and Sven are the proprietors, with collective experience covering mechanical engineering, marketing and sales. Sustainability sits at the heart of their brand; Sciu compensate for the CO2 footprint of their entire value chain from production and logistics through to distribution with a reforestation program.

Somewhat ironic however, is the fact that both of these new frames are composed of carbon, manufactured in state-of-the-art vacuum injection molding process. Though it isn’t yet underway, Sciu Bikes say they are supporting a university research program to be one of the first bicycle manufacturers to offer their customers a recycling and up-cycling program for carbon frames. Here’s a quick overview of the Aspen Enduro Bike and Juniper Gravel Bike…

Sciu Aspen Enduro Bike

The Sciu Aspen is a 158mm travel enduro bike with a four-bar suspension linkage, with a kinematic dedicated to air shocks. Its geometry is optimised around a 170mm fork, though it can take a 180mm or even a 160mm. Though the complete bike ships as a 29er, Sciu tell us the bike can be set up in a mullet configuration too, with a 27.5″ rear wheel.

The Aspen is available in sizes M-XL covering rider heights from 167cm to >190cm. Reach figures stretch across a 449.1 mm to 501.2mm range, with a consistent rear-center length of 436.6 mm. With the intended 170mm fork, the head angle sits at 64.4° paired with a 76.4° seat tube angle. Switching to the MX configuration slackens those off to 63.5° and 75.5°, respectively, and shaves around 10mm off the reach. The top tube is quite flat by modern enduro standards, connecting to a 455mm seat tube in size large.

The four-bar suspension linkage layout leaves heaps of room inside the front triangle for a full size water bottle. The shock itself runs through an interrupted seat tube, with a full size fender at the rear protecting the shaft and seal from whatever the rear tire picks up off the trail.

Sciu Juniper Gravel Bike

The Sciu Juniper gets a high-end carbon fork composed of Toray carbon fibers; it is 400mm long with a 50mm offset. The rear triangle features bosses for the mounting of a rear rack, with a maximum carrying capacity of 25kg.

The Juniper is Sciu Bikes drop-bar offering for gravel enthusiasts. Available in sizes S-XL, the Juniper caters to riders from <164cm to >190cm tall, with reach stretching across a 374mm to 397mm range. Its monocoque full carbon frame is composed of Toray carbon fibers giving ride to a claimed frame weight of 980g (52 cm).

The Sciu Juniper Gravel Bike has three dedicated mounts for water bottles; one under the down tube and two in the main frame (down tube and on the seat tube).

The Sciu Juniper is said to offer outstanding ride comfort coupled with excellent stiffness owing to the lowered seatstay, tapered top tube and extra voluminous bottom bracket area. Tire clearance is ample; it can fit a 45mm wide tire (700c) or, a 2.1″ mountain bike tire on a 650b wheel. Running an AXS front derailleur will limit your options here, though, reducing 700c clearance to 42mm maximum.

A 1x setup gives clearance for anything up to a 42T chainring. If you’re running 2x, a 39/53T double chainring is your maximum. The frame runs 12 mm thru axles and flat mount brake disc brake calipers for a 140mm rotor, though there is clearance for a 160mm rotor with use of an adapter. The Juniper runs a BB86 press-fit bottom bracket.

The “pure edition” refers to the frame along with carbon fork, while the “walnut edition”, gets you the frame and fork, as well as the SCIU carbon seat post and SCIU carbon stem with special headset for hidden integration of brake hoses and shifter cables.

It sounds good and all but I would love to see an investment in the actual frame design that would reflect environmental protection and sustainability rather than using an off-the-shelf open mould frame.

“the Juniper caters to riders from 190cm tall”

This sounds like a typo to me. The range of rider heights X where X 190 cm doesn’t look like there’s going to be any overlap at all.

>164 cm to <190 cm is more correct. Alternatively you could ditch the greater-than and less-than symbols and simply say the bike caters to riders of 164-190 cm height.
