Build & Motor

Component selection varies across the range, but the X0 AXS RSV model I tested came well-equipped. I did have non-stock components on the test bike, but for the most part, it was pretty close to factory specs. The SRAM XO transmission performed flawlessly throughout testing and works well with the extra torque from the eMTB. The Fox suspension—Fox 38 Factory, Grip X2 fork, and Fox Float X Factory shock—felt appropriately tuned for the bike’s intended use. Brake performance was more than adequate for most situations, with the SRAM Mavens delivering well-rounded stopping power.

The Bosch Performance Line CX Gen5 motor delivers its 100Nm of torque with a peak power of 750 watts, paired with the fully enclosed Bosch PowerTube 600wh battery. The battery is stored internally and is not removable, which maintains the clean aesthetics but limits flexibility for longer adventures or easy charging. The controls are refreshingly simple with basic buttons and no unnecessary screen distractions. This simplicity extends throughout the bike, there are no gimmicks or complicated systems, just a well-executed electric mountain bike that focuses on the riding experience. Bosch is also well-supported in New Zealand with a service agent, ensuring local support in case of any issues.

Battery life proved more than adequate for most full-day rides, though your km’s will vary significantly based on terrain, assistance level, body weight and riding style. Range-wise, expect anywhere from three to six hours of ride time depending on conditions and how heavily you lean on the assistance. The motor’s efficiency impressed me, it’s possible to extend range considerably by being judicious with power levels on easier sections.

Ride

During my few days of testing at Silvan Forest MTB Park, the Vala proved itself to be well-balanced across a variety of terrain. The bike pedals efficiently despite its 150mm of rear travel, never feeling sluggish on climbs or flat sections. The motor integration feels natural, intuitive – and there’s no jarring power delivery or awkward engagement. Instead, the assistance builds smoothly and predictably.

On technical climbs, the front wheel tracks with good precision, following your steering inputs exactly where you point it. This predictable handling helps build a ton of confidence—you know exactly where the bike is headed. The generous bottom bracket clearance means you’re not worried about crank strikes on rocky step-ups, while the rear suspension stays composed even wide open with minimal pedal bob interfering with your rhythm. In fact, during most of my testing I left the rear shock wide open, and it pedalled fine. The Bosch Performance CX delivers assistance that feels completely natural—it amplifies your pedal input smoothly but puts out grunt when you need to power over challenging sections. Despite running the smaller 27.5″ rear wheel, traction on steep, loose climbs is bloody excellent. The bike simply grips and goes.

Flipping the chip to the low setting changes the climbing game slightly. The seat angle slackens marginally but stays comfortably upright, while the bottom bracket drops 4mm – enough that you’ll need to pick your lines more carefully, but not so much that it feels overly low. The bike becomes more demanding on technical climbs in this setting. The front wheel needs more commitment to keep tracking properly, and overall climbing prowess takes a small hit compared to the high position. It’s a trade-off worth understanding, depending on your terrain.

The Vala’s descending capabilities are very well dialled. The 150/160mm travel package feels well suited to aggressive trail riding without venturing into an enduro overkill rig. The suspension is active and compliant, soaking up repeated hits while maintaining composure through rough sections. During my test period, I rode some of the rougher trails on offer at Silvan, and the Vala kept me upright and composed. Coming from the upper North Island, I don’t always have those sketchier, rocky, loose sections, so I was glad the bike was more than capable of handling these. It feels great descending—much closer to a regular bike feel rather than a heavier eMTB feel.

On corners is where the mullet setup comes into its own in tighter sections—you can throw the bike into turns without getting hung up, thanks to that nimble 27.5″ rear wheel. This was needed during testing on the tighter, steeper and rockier terrain, where the bike’s playful nature really comes to life. The frame feels balanced and sprightly, with the Bosch Performance CX motor delivering power so intuitively. The larger front wheel still rolls over obstacles efficiently while that smaller rear wheel allows for snappy direction changes that would challenge bikes with dual 29″ wheels.

The geometry strikes a modern balance without going to extremes. The 63.9° head angle in the low setting provides sufficient confidence for steeper terrain while remaining lively enough for tighter, more technical trails. The reach figures are contemporary without being excessive, and the effective seat tube angles keep you in an efficient pedalling position. The Vala is plenty capable across varying terrain, yet efficient enough for longer rides. The balanced character means it performs well across a broad spectrum of riding situations.

Perhaps not absolutely excelling in just one aspect of riding but rather taking a trail riding approach. I suppose you could say that the Vala plays things relatively safe. The geo, travel and spec are solid but perhaps not uber innovative. That said, the conservatism might actually be its main strength—it’s a bike that’s difficult to fault. The build quality is typically Santa Cruz: excellent attention to detail, clean cable routing, and solid construction throughout. The frame feels robust without being overbuilt, and the finish quality matches what you’d expect from a premium brand. Plus, I like that it’s engineered simply, as it means better functionality and reliability.

This Vala is bloody good fun! It’s one of the most well-rounded eMTBs I’ve ridden this year. The Vala strikes an impressive balance between capability and playfulness, efficiency and performance. It pedals everywhere well, is a very capable climber, and descends with absolute confidence. The intuition of the Bosch Performance Line CX Gen5 is dialled. The motor does what it’s supposed to and elevates the riding experience. The extra 100Nm update with Bosch Performance Line CX Gen5 rode exceptionally well, especially in eMTB mode, which I used for all testing. This update enhances sustained power, particularly at low cadences and in low gears, improving acceleration and climbing on steep terrain.

While it may not revolutionize the eMTB category, it represents a mature and thoughtful approach to eMTB that prioritizes the riding experience above all else. For riders seeking a premium eMTB that can handle diverse terrain without compromise, the Vala makes a compelling case.
