If you caught last year’s eMTB Shootout you may remember the longer travel SCOR 4060 Z LT review. This year we were excited to see just how fun and playful the LT’s little brother, the SCOR 4060 Z ST (Short Travel) would be. The SCOR 4060 Z ST XT is the model we received for our 2023 eMTB Shootout, it is a 140mm travel eBike variant of their analogue 4060 ST, equipped with a Shimano EP8 motor and a pair of 29” wheels. We had a lot of fun testing this bike, with the signature SCOR playful manners. Let us tell you more about it and share how it stacks up to the competition in this year’s eMountain Bike group test.

2023 EMTB SHOOTOUT SERIES – This bike was one of 13 that our staff thoroughly tested with absolute objectivity in mind. From different types of riders to terrain, our goal is to present the best and most honest information possible to help you make your best decision. Of course, we’d love to thank Fox Racing and Schwalbe Tires for being invaluable partners to this series and making it happen.

FRAME AND FEATURES 

The SCOR 4060 Z ST XT is the top-tier trail eBike in SCOR’s range, with a 140mm travel rear end and 150mm travel fork rolling on a pair of 29-inch wheels. The 4060 is powered by the Shimano EP8 drive unit with a 720Wh battery. Out back the 140mm of travel is controlled by SCOR’s lower-link driven “Instant Center Linkage” suspension system, a dual-link design that has some tuned kinematics to give efficient pedaling characteristics and plentiful “pop” on the descents.

SCOR offers their 4060 Z platform exclusively in carbon fiber. The frame has full internal routing for the cables with ports at the side of the head tube. There is a bottle cage mount and tool mount inside the front triangle; the signature ribbed SCOR chainstay guard; and a generous downtube guard to protect the motor and a removable battery cover. The frame uses a SRAM UDH for easy replacements or if you’d like to upgrade to the new SRAM AXS T-Type derailleur. On the lower link, there is a flip chip to allow for the switch from the ST to LT mode in combination with a different shock. The headset is an angle adjust model, giving a “slack” or “steep” head tube angle by rotating the cups in the frame.

DRIVE UNIT AND ELECTRONICS

The SCOR adds to the tally of Shimano STEPS EP8 motors, as featured on seven of our 13 bikes in this year’s eMTB shootout. The EP8 delivers 85Nm of torque for its 5.7lb (2.6kg) weight and is spec’d frequently as a safe bet for good performance. The battery is a removable integrated Darfon unit with a 720Wh capacity, with full Shimano support to facilitate easier service if an issue is encountered. It uses an Allen key bolt to secure the battery in place within the downtube to prevent rattling. The SCOR uses the EM800 display and EM-800L assist switch to show the key information and offer control of the different functions and modes. The modes are ECO, TRAIL and BOOST, and the Shimano E-TUBE PROJECT app allows the user to tweak two customizable profiles to obtain the feel and assistance levels desired.

SCOR 4060 Z ST XT Geo Sheet

The geometry of the SCOR 4060 Z ST points towards its fun-having intentions, with a compact wheelbase given its comfortable cockpit size that keeps the rider in a commanding position but allows for quick changes of direction and easy manuals and hops.


GEOMETRY

The SCOR 4060 Z ST is given geometry for all-round fun, with a focus on a short rear end and low standover to encourage playful antics on the trail. There’s a size range of Small to Extra Large, with low seat tubes and stack heights to allow each rider to choose between multiple sizes. In the slack headset position, the size large tested with a 440mm seat tube length has a reach of 485mm and stack height of 625mm. Shared across all sizes are a 64.5-degree head tube angle, 78.5-degree seat tube angle, 435mm chainstay length and 29mm bottom bracket drop. The large has a wheelbase of 1,235mm, shortest in this year’s shootout.

BUILD SPECS 

SCOR currently offers their 4060 Z ST in a choice of two different specs – the $7,499 SLX build, or the $9,499 XT build, which we reviewed. The XT build features a selection of components that wouldn’t be out of place on a hard hitting enduro bike, signifying the “party” intentions SCOR has for their trail eMTB. Leading the charge is a Fox 38E Factory fork with 150mm travel, which is paired to a Float X Factory rear shock. As the XT in the name suggests, there’s a full Shimano Deore XT groupset, with 4-pot XT M8120 brakes stopping on 203mm rotors, a 12spd drivetrain with 10-51t cassette, and a 165mm XT M8150 crankset. The cockpit is a 35mm long Burgtec Enduro MK3 stem and SCOR 20mm rise carbon bar, with 31.8mm diameter. A BikeYoke Divine dropper, with 125mm – 185mm drop depending on the frame size, is topped with a Fizik Terra Alpaca saddle.

Rounding out the specs is a DT Swiss H1900 SPLINE alloy wheelset, which is usually wrapped in a Maxxis Assegai EXO+ and Dissector DD tire combo, but was fitted with our control tire spec for this shootout. Thanks to Schwalbe, for the 5th year running we’ll be running their trusty tires on all of the bikes in the shootout to provide a fairer comparison from bike to bike. We have the Magic Mary Soft Super Gravity in the front and Big Betty Soft Super Gravity in the rear on all bikes in this year’s group test.

THE DIRT

SETUP | Setting up the SCOR 4060 Z ST was a fairly easy operation for all testers, aside from the hidden shock shaft making it slightly trickier to accurately determine the exact sag. The window of sag felt to be fairly wide, with anything between 25-32% performing well and allowing for the character to be tweaked slightly.

ELECTRONICS & INTEGRATION |Being a Shimano EP8 bike, the performance was dependable and predictable, just not quite as powerful as the other motors on test when it got to the steeper grades. SCOR have done a good job at integrating the Shimano system though, with a neat finish all around that reflects the price tag. We don’t love the location and style of the power button, just above the bottom bracket, as it may get gunked up and hard to press if you’re regularly riding in super nasty conditions.

SCOR 4060 Z ST XT Climbing

CLIMBING | The SCOR is a competent climber for the most part, with reasonable pedal clearance and a comfortable seated position for most riders. Taller riders noted the slightly more relaxed seat tube angle once the saddle was fully extended to their height, but it was still manageable until the grades got steep enough to warrant the largest rear cog. In this gear it was immediately evident that the short rear end length is not a positive for everything. Steep and technical climbs left the front end keen to lift and the balance between maintaining front end or rear end traction required a lot of effort and concentration. Robert set his uphill wheelie record on this thing without actively trying. The flip side of this is the ease at which you can lift the front end to clear ledges, or just to play on the back wheel on your way up the hill. The EP8 combined with a relatively good pedaling platform made for an efficient feel when hammering the pedals, slightly reducing the overall comfort but still giving an acceptably cushioned ride for long days in the saddle.

DESCENDING | On the way down the hill, the short rear end, relatively low overall weight, and poppy suspension feel really come into their own. In short, the 4060 Z ST is a serious amount of fun. There was no denying the smiles and good times we all had aboard this eBike. It manages to pack a healthy dose of capability with that fun-loving attitude.

We did notice it fell a bit short of some more stable or supple rigs when the terrain gets particularly rough or the hits particularly large. It’s also a bit flighty when the ground is loose and an extra soft-off-the-top suspension feel is desired. A more active approach is required to select lines that favor the firmer overall suspension feel in more gnarly terrain, but this is made easy by the SCOR’s agility. The rear end stiffness is not ultra-high, which helps to allow the rear wheel to find its way down rough terrain, but can occasionally lead to a slightly vague feeling when the 4060 Z ST is pushed hard in high traction corners or compressions.

FINISH AND VALUE | The component spec on the SCOR 4060 Z ST XT is very solid and well considered, with no parts standing out to need replacement if we were to buy it. The frame finish is clean, and the details well looked after, though you’d hope so for the price tag. SCOR has delivered this XT build kit at an acceptable price point, but when compared with the similarly spec’d Fezzari in the shootout, it falls some way behind in terms of value. Compared to the Marin – a bike in a very similar segment of the eMTB market aside from its alloy frame – the extra $3,200 would be hard for us to justify if it were our own money, but there’s no denying the higher quality of the SCOR all around.

The Wolf’s Last Word

SCOR continues to impress us with the grin-inducing fun factor of their bikes, with the 4060 Z ST XT in this year’s shootout proving no exception to the rule. In terms of value, it lands in the middle of the road, with its high-quality frame and solid build kit, but falls short of the likes of the Fezzari and Marin.

WHO’S IT FOR?

The SCOR 4060 Z ST XT is not a bike that will offer advantages for all-out speed or steep terrain climbing, however for riders looking to pop and play their way down the trail it’s a stellar option that had all testers smiling from start to finish. A comfortable climbing position for flatter grades, an efficient pedaling platform and the 720Wh battery mean it’ll happily log big miles, whether it be in the backcountry or self-shuttling some groomed flow trails. If you are an active rider who likes to spend as much time in the air as on the ground, SCOR has done a great job of making their eMTB ride like their non-E version.
