The new Vala is Santa Cruz’ first attempt on a Bosch-powered emtb. Like many other brands these days, Santa Cruz has gone from Shimano to offering both brands. According to my local Santa Cruz contact, the brand will be opportunistic when choosing a motor and not locking themselves to one motor system. And that shows, now Santa Cruz is offering Fazua and Bosch in addition to Shimano motors.


Bosch Performance CX gen5​

The bike does of course get the latest CX gen5 motor. And it gets the 600 Wh battery that is fixed inside the frame. It seems more and more brands decide to fix the battery to the frame these days. If you don’t need a detachable battery, perhaps to be able to charge it, then there are advantages to a fixed battery. It saves weight, complexity and cost. We quite enjoy the new 85 Nm CX motor, it brings a new level of bike control without having to drop the motor power quite low. And it's a silent motor, both under load and while coasting, read more about it here.

The Vala rear suspension​

To me though, there are bigger news and changes on the Vala. This is a mullet bike with a smaller 27.5 rear wheel matched with 150 mm travel and 160 mm at the front. Sounds familiar? It’s the same as the Santa Cruz Heckler, a bike that has now been replaced with the Vala. Prior to the Heckler launch, I was speculating whether Santa Cruz would be able to implement their signature VPP suspension on an emtb. The lower link of the classic VPP is almost touching the bottom bracket, leaving no space for a motor.

The lower link was raised to give room for the motor in the Heckler frame.
Santa Cruz makes a case for going four-bar on the Vala,  but the 2020+ Heckler did of course present the same challenge.

The Heckler appeared and it did come with the VPP rear linkage. Well, almost, the lower link was moved to make room for the quite compact Shimano-motor. But Santa Cruz was happy. They had achieved their goal of making an emtb with their cherished VPP suspension and a frame that looked like the Bronson, the non-assist counterpart of the Heckler.

Fast-forwards five years and, to the surprise of many, the VPP is gone. I can’t help but think the compromise of combining VPP with a motor ended up being too big. Santa Cruz says they went with the new four-bar design so they could move the shock out of the seat tube to make room for a longer dropper post, and to free up space for the motor.

The VPP design was loved by many, and I enjoyed how the rear wheel tracked the trails. But I struggled with the anti-rise on my old 2014 Bronson, the rear would lift when braking hard, tipping me forwards and compressing the fork. Also, it couldn’t be described as a poppy rear end, it took a bit of work extending the rear shock and getting the back wheel of the ground. Looking at the kinematics graphs, the four-bar Vala looks very different to other Santa Cruz emtbs.

Santa Cruz Vala frame geometry​

Compared to previous Hecklers, the head angle is down by 1* or more. They always had relatively steep seat angles, and so does Vala at just over 77*, depending on the flip-chip position. There is a chip that will move the bottom shock attachment slightly, taking the head angle down from 64.2 to 63.9*. The seat angle too is only adjusted by 0.3*.

Chainstays are size specific, or test bike in size L has 444 mm stays, and 2 mm more in the HI position. This results in very minor changes to the wheelbase which is 1.269 mm and 1 mm more in the HI position. These are very minor changes. So, what’s the point? To me, the 4 mm lower bottom bracket was the biggest deal of selecting the LO position. As I can’t remember a single pedal strike during the testing, the 340 mm BB height made me very happy. I enjoy a slightly lower bottom bracket height when descending and cornering.

More details​

Did you notice? There are no cables going through the headset. Also, there is no headset block, restricting steering rotation. I’m not surprised Santa Cruz has omitted headset routed cables. It seems they’re being a bit conservative about some trends. When I bought a Santa Cruz Bronson in 2014, it was partly due to the threaded bottom bracket. The brand decided against using pressfit bearings.

Cables are routed outside of the headset!
No knock-block headset limiting the steering.

Riding the Santa Cruz Vala X0​

On my first ride, there was a situation that said much about this bike. I was going down a long, steep and straight trail and speed was building up quickly, so I decided to brake a bit. The Maven Silvers scrub so hard. Meanwhile, the anti-rise of the rear suspension ensures the rear end doesn’t lift. That was a concern for me as when braking hard on my old 2014 Bronson, the front was diving. This time, the bike remained level, and it seemed to inch lower to grab onto the surface, like a cat. I was left impressed by how the rear end tracked to maintain grip and control.

This stellar performance left me disappointed with my choice. Why did I decide to pull the brakes? There was no need, and now I lost all my speed. The braking performance and rear wheel behavior inspires confidence. Combined with the Schwalbe Magic Mary Soft & Softer radial tyres, the grip and stability on wet autumn trails was impressive.

Tracking very well
The Super Soft Magic Mary Radial offered lots of grip in difficult conditions
Sram Maven Silver Stealth brakes are probably my new favourite brake.

Riding treacherous autumn trails, it felt like leveling up riding the Vala. I just had to dare go faster to realize I wasn’t pushing the bike, to realize there was grip to be had over wet rockgardens. Sure, the tyres were losing grip. But it was happening in slow motion, the sticky tyres were letting go slowly and I had time to react.

Less steep trails​

The rear suspension and choice of tyres would continue to impress us. Sure, the radial Magic Mary Gravity rear wheel is a slow roller. Riding on asphalt, the Vala rider was lagging behind when descending. And the tyres made a rumbling noise, which was pretty much the only time this bike was audible.

Playfull in the less steep too.


I noticed I was riding seated more than I used to. I was surprised by how well the smaller bumps from the trails were dealt with. The well damped, grippy tyres helped a lot and the rear suspension remained active even while pedaling.

The heavy and supple tyres have such a positive impact on the ride. But wouldn’t that result in a slow and more sluggish steering response? No, not in this case, and I believe that’s down to the light Santa Cruz Reserve carbon wheels. Combining heavy tyres with a light rim keeps the total rotating mass down. It’s such a great combination. I fear the experience might not be the same on cheaper Vala builds with heavier wheels, but I don’t know, I might be wrong.

Santa Cruz Reserve wheels are nice!


I always viewed the original Heckler as a fun trailbike, a light bike that is inspiring on less aggressive trails. Even though the Vala has more aggressive geometry, it’s a light bike too, weighing 22 kg including pedals. Sure, the slacker head angle and longer wheelbase changes the bike a bit. The steering does feel a bit slower in low speed, sharp turns. But that’s fine, it's not much of a sacrifice as the Vala still feels responsive and light for less agressive trail riding.

Climbing​

Riding slippery trails, the Vala was a great climber. Sure, the 444 mm chainstays aren’t long enough to make it a climbing specialist. But these are challenging conditions, a few more mm on the rear end wouldn’t have made a difference, we got up the steepest climbs thanks to rear wheel traction and motor power. This bike climbs well enough and then some, there is no way I would wish for a longer rear end and trade off other characteristics of this bike.

Conclusion​

With the Vala, the ambitions of making the bike look like its non-assist counterpart is gone. And I for one can’t see any downside. To me, the bike still looks like a Santa Cruz with the tube shapes and single-color paint job.

The new frame geometry combined with the redesigned rear suspension has transformed the 150/160 mm travel offering to a highly capable descender. It rides like a burlier bike than it actually is. And thankfully, actually being less burly makes the Vala enjoyable at lower speeds too.

As you know by now, I like the Vala a lot. But it also makes me a bit sad. I can’t see myself ever spending anywhere close to $11.499 on an emtb. And this is what PON, the owner of Santa Cruz intended. The Vala is only available with a carbon frame, Santa Cruz is targeting the high-end market. If you want a cheaper bike than the base Vala R at $7.299, PON might suggest you look at the Focus Jam2 that can only be had with an alloy frame.

I'm sure its good enough, it could have any name on the down tube though? its a bit meh!
Its not enough different to tempt me away from my Wild back to a Santa Cruz.
#NeedsMorePurple and to look a bit more exciting!

I have a Heckler MX with the 504wh battery. I have reached dream bike status (for me) with it after installing a Cascade link, 160mm ZEB fork, Rock Shox Deluxe shock, We Are One Composites wheels, One Up Carbon Ebar, SRAM AXS drivetrain, Maven brakes and I've tuned each power setting exactly how I like them. BUT I want a VALA so bad! lol
 
What about motor drag when riding faster than limiter? does the cranks de-couple from the motor or should drag be expected like gen4 or comparable motors?
 
My guess is that the VPP decision was just as much to deal with the increased weight and VERY different weight distribution of an eMTB.

It’s more than kinematic, the heckler and bullit suspension stops working under braking, it’s literally that bad

I’d say that’s a bit dramatic as an owner of both a Bullit and Nomad 6. The Bullit anti rise numbers are a little higher than the Nomad and can be felt a bit on braking but it’s not wildly different than the Nomad. I’d say the biggest thing is the shock and the shock tune. When I first got the Bullit I was not super impressed and felt as you do that the rear was just harsh and not active at all which then become worse under braking. With some shock testing back to back I discovered the heavily digressive rockshox compression tunes are largely responsible for this as just taking the fox off the Nomad as swapping it made them much more similar bikes. It does still have more anti squat and anti rise but it’s a much better bike now with a different shock. That said 4 bar bikes all have less anti rise than VPP and there’s pros and cons to each. 4 bar will actually rise (less than 100% anti rise) which lift the rear suspension and puts it in a softer portion of spring rate so it’s going to feel more active. Lower link vpp all hover around 100% anti rise which technically means they are completely neutral. So flatter high speed chunky stuff on the brakes you’re probably going to want 4 bar. Dropping into a steep chute on the brakes and you’ll probably want vpp. Both now days are good and both can do either it’s just a difference in design and as all suspension there are trade offs.

I'm not comparing the Nomad 6 to the Heckler or Bullit, I had one for 18 months and its proabably my favourite bike i've ridden! It absolutely works with VPP as do all they're other pedal bikes.
However, the Heckler and Bullit have 160% anti-squat because of how the linkage had to be positioned for the motor to fit, that is a glorious amount of pedal jack, I certainly felt it and also how dead the suspension was under braking. They are both good bikes in some ways, but suspension performance, the Vala is miles better than both!

Well your original comment was braking performance not pedal kickback. The two are not the same thing as anti rise is the influencer on braking and the two bike I’ve used as examples are very close to each other and neither is as low as the Vala which was the point I was making of VPP vs 4bar in general. As for anti squat yes the Bullit and Heckler has more and yes it is noticeable but I’d say it’s still not terrible (at least not the Bullit) and both drop off quicker to where they’re all (VPP models) about the same at just past sag. Also as said the biggest influencer I found was the rear shock, maybe the initial high rate of compression damping accompanied by the anti squat just makes for a harsh ride. No doubts the Vala will ride more active and probably even more so than their pedal VPP bikes which is why I think SC will be monitoring the success of the Vala and won’t be surprised if they make a decision for all their bikes based of it. If people prefer the braking and activeness of it overall then I wouldn’t be shocked if you see analog 4 bars from SC later. After all it’s easier to design and work with which means less engineering time which means less R&D cost and since they still charge a premium that’s more profit. Remember at one point with the Nomad 4 SC said they’re trail and XC bikes will remain upper link VPP and then with the success of the Nomad 4 and how many preferred the lower link performance (which if anyone rode a v10 prior they already knew and knew the limiting factor was lack of dropper post at the time) and we’ll look at the lineup now.

I was giving you another example of how messed up the kinematic is, I know the difference between anti squat and anti rise and they’re both not optimal. Rear performance under braking is as messed up as the pedal jack, which I’m sure you know. E-storia helped on the heckler I had but only minimally, rear suspension was still dead under Braking and traction was minimal. Even Rob roskopp was asked why he was riding an unno emtb rather than an SC, and his reply was ‘I’m riding a bike that works’ you can argue your point but it’s pretty common knowledge the kinematic was bad and the reason they’ve gone to the 4 bar

You mean after Rob was terminated from SC. Now he’s with Specialized so don’t be surprised when he’s on a Specialized and says it’s the best thing ever. That’s how marketing works.

He wasn’t working with Unno though was he? No, had absolutely nothing to do with them marketing/sales wise, he was just riding their bike
 
It’s also you interesting use the Unno as your justification since it’s anti squat is very similar and can even be way worse if not setup absolutely perfect and has a higher degree of pedal kickback. But again getting back to original statements the reply was to your comment of “the suspension stops working under braking, it’s literally that bad”. That means it is exactly like a hard tail under braking. To which I was replying saying you are being a bit melodramatic as it is not that bad and not even far off of the analog vpp bikes. Now you’re going back and forth between the two rather than staying on topic at hand. So again are you saying they become hard tails under braking yes or no?
 
Knut, there is some chatter online about the Bosch Gen5 having a clutch mechanism that disconnects the motor while coasting, and although it was designed for noise reduction, it would also serve as an anti-Pedal Kickback device.

Can you check if this is true?

Just remove the shock on the Vala, turn the bike on, push it forward a few meters holding the suspension up so that's it's definitely in its freewheel mode, then compress the rear suspension and watch to see if the cranks rotate backwards. Of course, this only works with a decent rear hub (install a Vesper for the ultimate test!) but if the cranks don't rotate backwards, or even only rotate backwards after 70% travel or the like is used, this is very telling and a heck of a design feature.

If true, this puts the Bosch on another level from the only reasonable competitor (the DJI) as it's essentially including an anti-PK device (i.e. O'chain, Sidekick hub, etc) for a very small weight/ cost penalty.

Thoughts?

Rob Rides MTB show how the noise reduction is achieved in this video around the 1:00 min mark

 
What I'm seeing is that he is rotating the crank spindle backwards. What we need to see is if rotating the silver colored gear for the front chainring ALSO pulls the crank spindle backwards. That's what will determine if the Bosch will hide PK. I don't think it will.
