Scott Patron ST 900

The Patron ST 900 is Scott's full-power e-MTB for riders who want a properly capable descender alongside serious climbing assistance, rather than a bike that's mostly about the motor. A carbon frame carries 170mm of front travel and 150mm at the rear, built around a Bosch Performance Line CX motor and an 800Wh battery, so the emphasis stays on getting you up long climbs in good shape for whatever comes down the other side.

Bosch power that's built for big days

The Performance Line CX motor and 800Wh PowerTube battery are the core of this build, and together they're aimed at riders doing long, sustained climbs rather than short hops between trailheads. Like all EU-specification e-bikes, assistance cuts out at 25km/h, so the motor's job is getting you up the hill efficiently rather than adding speed once you're rolling. A Bosch Kiox 400C display and Mini Remote handle the everyday controls, and the bike charges from a 4A charger.

If you want more range than the fitted 800Wh gives you, Bosch's PowerMore 250 extender is compatible with this bike's holder and cabling, taking combined capacity up to 1050Wh. That's worth knowing as an available upgrade rather than something in the box: the extender and its mounting hardware are a separate purchase, and 1050Wh describes battery capacity, not a promised number of miles.

Suspension, brakes and tyres for serious descents

The ST in Patron ST 900 refers to the longer-travel version of this frame, and it shows in the suspension: a RockShox ZEB Ultimate fork with a Charger 3.1 damper and ButterCups up front, and a RockShox SuperDeluxe Ultimate piggyback shock at the rear, run through Scott's Virtual 4 Link linkage with an adjustable head angle. The rear shock sits concealed within the frame, which keeps things tidy and protected but means sag and rebound adjustment are a bit less straightforward than on a bike with an exposed shock; Scott fits an external sag indicator to help with that.

Braking is Shimano XT four-piston, backed by Bosch's eBike ABS Pro system on the front wheel, with 220mm and 203mm rotors front and rear. ABS Pro is designed to reduce the risk of the front wheel locking up under hard braking, and it offers two selectable levels, Trail Pro and Race, so you can choose how much the system intervenes. Because ABS Pro is tied into the bike's braking hardware, Bosch's guidance is not to substitute different brakes on this build. Power reaches the rear wheel through SRAM's wireless GX Eagle AXS Transmission, a 12-speed setup with no cables to route through the frame, and grip comes from Schwalbe's Magic Mary and Albert tyres in gravity casings, sized 29 x 2.5in and aimed at rough, technical trail riding rather than smoother all-day trails.

Choosing between the Patron builds

Scott sells more than one bike carrying the Patron name, and it's worth keeping them separate before comparing offers. This Patron ST 900 has an official UK RRP of £9,299.00 and specifies the Bosch CX motor, RockShox suspension and Shimano XT brakes with ABS Pro described above. A separately specified Patron ST 900 Tuned build instead uses a Bosch CX-R motor, FOX suspension and SRAM Maven brakes, so it's a different specification behind a similar name. The regular Patron 900, meanwhile, drops the ST altogether: it runs 150mm of travel at both ends with a TracLoc remote lever rather than this bike's 170mm fork and piggyback shock, and carries a lower official UK RRP of £8,299.00. Both figures are official list prices rather than a comparison of what either bike costs to buy today, but they're a useful guide to how Scott positions the two models relative to each other.

Sizing and fit across S to XL

The Patron ST 900 comes in S, M, L and XL, each with its own published geometry. Scott offers an individual, measurement-based fitting tool on its product page rather than a simple height chart, so it's worth working from reach and stack figures for your own body rather than a generic size band. Cockpit and dropper equipment also scale with frame size, with dropper travel and handlebar rise both increasing on the larger frames, and maximum seatpost insertion doing the same; the size-specific figures are laid out alongside the geometry so you can check your frame's exact spec before choosing a replacement post or bar.

Ownership essentials worth knowing

Scott's frame-and-rear-end manufacturer guarantee needs the first buyer to register the bike within ten days of purchase, and its headline five-year term depends on at least annual servicing at an authorised dealer; miss that and the term drops to three years, with components themselves sitting outside this guarantee. The bike comes with a rear-fender light fitted, and the cabling for a front light is already run through the frame, so adding one is straightforward if you plan to ride after dark, though a front light isn't included as standard. All told, the combination of that much motor, that much travel and a battery sized for proper days out is what makes this bike worth owning if you're already riding demanding trails: it's built to let you keep climbing back up for another lap rather than calling it a day early.
