Scott Patron ST 900 Tuned

The Scott Patron ST 900 Tuned is a full-power carbon e-MTB built for riders who want serious descending equipment and a large battery without giving up assisted climbing on demanding ground. Scott rates it for its toughest usage condition, and with 170mm of travel up front and 150mm at the rear on an integrated-shock carbon frame, it's set up to deal with rock gardens and technical descents rather than smooth singletrack. If you want to keep climbing all day and still have something substantial underneath you on the way back down, that's the appeal this bike is built around.

A motor and battery built for long days

Power comes from a Bosch Performance Line CX-R motor, run through a Kiox 400C display and Mini Remote, with the usual 25km/h UK assistance cut-off. The fitted 800Wh PowerTube battery is already a substantial capacity for a full-power system, and the frame is ready to take Scott's compatible 250Wh PowerMore add-on, which brings combined capacity up to 1,050Wh. That extra battery is an optional purchase rather than something included in the price, and it's worth being clear that 1,050Wh is a hardware ceiling rather than a promised riding distance; Scott's UK specification for this build doesn't publish a mileage figure or a fitted torque setting, so treat the numbers as capacity rather than a guaranteed day's range.

Suspension and brakes built for descending

The descending side of the spec is where the Tuned name earns its keep. A FOX Podium Factory GRIP X2 Air fork delivers the full 170mm up front, paired with a FOX FLOAT X Factory EVOL shock at the rear, and Scott specifies a two-position lever so you can firm the suspension up for a climb and open it back up for the way down. Stopping power comes from SRAM Maven Silver Stealth four-piston brakes on sizeable 220mm front and 200mm rear rotors, a sensible pairing for a bike this capable and this heavy. It's worth flagging that ABS Pro, which appears in some UK promotional wording for this model, isn't part of this build's actual brake specification. DT Swiss HX1700 wheels are wrapped in a Schwalbe Magic Mary up front and an Albert at the rear, both in Scott's grippier Gravity casings, tyre choices aimed squarely at loose, rocky or root-strewn terrain rather than groomed trail centres.

Electronic shifting and finishing kit

Shifting comes from a SRAM X0 Eagle AXS Transmission, a wireless setup mounted directly to the frame via the UDH standard rather than through a traditional derailleur hanger, paired with a GX Eagle 10-52 cassette and 34T chainring. The 780mm Syncros Hixon iC carbon bar and Syncros Duncan dropper post round out a cockpit built for aggressive trail use, and there's an integrated rear-fender light plus a pre-installed front-light cable, useful if you ride into the evening. A front light itself isn't fitted, so budget separately if you want one.

Choosing your size

The Patron ST 900 Tuned comes in four sizes, S through XL, and both dropper travel and handlebar rise scale up through the range so taller riders aren't left with a cockpit sized for someone shorter. One detail worth checking before buying: Scott's own overview for this bike references TracLoc suspension control, but the exact remote fitted and how many positions it offers aren't confirmed in this build's detailed specification, so it's worth confirming that function on the specific bike you're buying rather than assuming it matches another Scott model.

Ownership limits worth knowing

Scott's 130kg maximum system weight covers bike, rider and any carried luggage together, not a separate rider-only limit. The platform's frame manual rules out coil shocks, and both battery and motor fixation work are reserved for authorised dealer tooling rather than home fitting. Scott's longer five-year frame guarantee depends on documented annual dealer servicing, dropping to three years without it, and UK registration needs to happen within a year of purchase to stay eligible. At roughly 24.4kg, this is also a genuinely substantial bike to lift onto a rack or manoeuvre off the trail, and the frame's integrated shock and cable routing make some servicing and component swaps less straightforward than on a bike with external routing.

Matching the right Patron ST 900 Tuned

Because Scott has used this exact name before, it's easy to end up comparing the wrong bike. An earlier Patron ST 900 Tuned tested in 2025 used a Bosch Performance Line CX motor, a FOX 38 fork, a FOX FLOAT X NUDE shock, SRAM GX AXS shifting and Magura MT7 brakes with Bosch ABS Pro, none of which apply to the later UK build described here, which runs the CX-R motor, FOX Podium Factory suspension, SRAM X0 AXS and SRAM Maven brakes without ABS Pro. There's also a separately named Patron ST Tuned, which uses an Öhlins fork, a RockShox shock and Shimano ABS Pro brakes rather than this build's fitted equipment, so it isn't simply another spec option of this same page. Match an offer's actual FOX Podium, CX-R and SRAM Maven components against this list rather than relying on a year label alone, and you'll know you're getting the descending-focused package the Tuned name is meant to represent. For a rider planning genuinely big backcountry days, the size of that fitted battery, and the option to add more capacity later, is what turns this from a bike you ride until the charge runs out into one you can plan a full day's riding around.
