The Giant SyncDrive Pro 3X has plenty of muscle, but its delivery is what stood out during my time on the Stance E+ 1. Some eMTB motors give you a sharp hit as soon as you start pedalling. The Giant builds its assistance progressively, easing the power in and making climbs feel natural and controlled.
That character suits riders who want strong assistance without every pedal stroke feeling like a demand for acceleration. There is plenty of grunt once you’re moving, but it arrives in a way that makes it easier to manage.
Giant Stance E+ 1 — 2027

Our verdict
A superb option for riders who favour speed, flowing trails and assisted climbs. The Stance carries its weight well and retains some playfulness, but its size is harder to ignore on cramped technical terrain. The shock offers three useful positions, although setup scope remains limited. Initial brake bite needs improvement, with further bedding-in expected to help.

Giant SyncDrive Pro 3X: the system on test
I tested the SyncDrive Pro 3X in the Giant Stance E+ 1, paired with an 800Wh EnergyPak battery and RideControl Dash 2 display. Giant claims up to 100Nm of torque and 800W of peak motor power. Those are manufacturer figures; the riding impressions here come from using the complete bike on the trails.
The system offers five assistance levels and Smart Assist, which automatically adjusts support. My observations focus on power delivery, climbing, noise and the everyday experience of changing modes.
Testing the SyncDrive Pro 3X on the climbs
The strongest part of the SyncDrive Pro 3X’s performance is how progressively it introduces assistance. It doesn’t feel short of power, but there is less of the initial thump that can make a powerful eMTB feel eager to run away from you.
On climbs, that makes the support easier to work with. The motor adds to your pedalling without the same abrupt surge, giving the bike a controlled feel as you build momentum.
On the 29in-wheeled Stance, selecting an easier gear and keeping the pedals turning briskly helped get things moving uphill. Once underway, there was enough assistance to stay on top of the gear without feeling that I constantly needed another downshift.
By “staying on top of the gear”, I mean maintaining a comfortable pedalling rhythm instead of struggling to force each pedal stroke. The Giant provided useful support here, with plenty in reserve as the climb continued.
Just as importantly, that assistance didn’t feel intent on breaking rear-wheel traction. Grip still depends on tyres, ground conditions and rider position, but the progressive delivery made the power feel manageable. Strong assistance is more useful when you can put it into the ground.
Noise, display and controls
Motor noise was broadly comparable with the Specialized 3.1 I recently tested. Neither struck me as noticeably quieter in normal riding, although this is a riding impression rather than a measured sound comparison.
The controls were straightforward. The large display sits close to your thumb, and changing assistance modes was easy. Each button press had a satisfying click, giving clear feedback that I had actually made an input.
That sounds like a small detail until you’re trying to change modes while concentrating on the trail. Positive button feedback helps keep the interaction simple.
Battery performance
My rides included plenty of climbing and regular use of the higher assistance modes. Over that testing, I didn’t notice sudden battery-level drops or an alarming loss of assistance.
I didn’t ride the 800Wh battery to empty, so I can’t give a measured full-charge range or judge how the system behaves right at the bottom of its charge. The experience during my rides was reassuring, but it would be misleading to turn that into a mileage claim.
The competition: Specialized 3.1 and Shimano EP6
The closest comparison from my recent riding is the Specialized 3.1. The Giant felt in a similar performance bracket, but marginally more restrained and less punchy. To me, its assistance was easier to manage as it first built, with useful low-down support introduced progressively.
Riders who enjoy an immediate burst of acceleration may prefer the Specialized’s character. The Giant appealed for the way it eased into its effort, especially when maintaining control mattered more than getting a sharp shove.
Specialized Turbo Levo 4 Alloy: a 3.1-powered alternative
The Levo 4 Alloy below uses the Specialized 3.1 motor. It is a different build from the Comp Alloy I tested, so my motor comparison should not be read as a review of this base model’s suspension, brakes or drivetrain.
Specialized Turbo Levo 4 Alloy
The base Levo 4 Alloy offers the 3.1 motor and 840Wh battery; it is a different build from the award-winning Comp Alloy.
+ Pros
- Latest Levo 4 platform under £5,000
- Powerful Specialized motor system
- Large 840Wh battery
- Adjustable geometry and mixed-wheel setup
− Cons
- Needs careful setup to feel its best

Why it makes the shortlist
The Specialized Turbo Levo 4 Alloy needs a small but important explanation.
Our Best Overall eMTB 2026 award belongs to the Turbo Levo 4 Comp Alloy, not this £4,799 base Alloy model. The Comp currently costs £5,499, so it does not qualify for an eMTB-under-£5,000 guide and we are not transferring its award to its cheaper sibling.
What the Alloy does share is the heart of the Levo 4 platform.
That means Specialized's 3.1 motor producing 105Nm and up to 810W, paired with a huge 840Wh battery. The M5 aluminium frame has 150mm rear travel, mixed wheels, SWAT storage and considerable geometry adjustment. Up front is a 160mm Marzocchi Bomber Z1.
We've ridden the more expensive Comp Alloy extensively, so our review is useful for understanding the Levo 4 chassis, motor and overall character. The cheaper bike is not identical, though. Marzocchi suspension, SRAM Eagle 70 mechanical Transmission and DB8 brakes bring the specification down to meet the price.
The huge advantage is that none of this removes what makes the current Levo interesting: enormous usable battery capacity, a powerful but tuneable motor and a chassis that can be adjusted around different riders and terrain.
If you want the absolute specification bargain, buy the Canyon. If you want Bosch and dealer ubiquity, start with the Cube. The Levo makes its case through the complete platform and how much control Specialized gives you over it.

Canyon Spectral:ON CF 7: the Shimano EP6 comparison
Compared with the Shimano EP6 in the Canyon Spectral:ON CF 7 I tested, the SyncDrive felt more powerful. These impressions come from different complete bikes, so gearing, tyres and setup also influence the result. They describe how the systems felt on the trail rather than a controlled motor-only comparison.
Canyon Spectral:ON CF 7
Our tested carbon-frame trail pick, with an 800Wh battery and mixed wheels. Canyon currently lists it at £3,749, coming soon.
+ Pros
- Full-carbon frame at an exceptional price
- Removable 800Wh battery
- Proper Maxxis trail tyres
− Cons
- Suspension and brake feel do not fully match the quality of the frame

Our verdict
The Canyon Spectral:ON CF 7 remains the benchmark for outright value at this price. It combines a full-carbon frame, 155mm of rear travel and a removable 800Wh battery at a listed £3,749; Canyon currently marks it coming soon.
Electric MTB UK has tested the Spectral:ON CF 7, and the frame is the standout. It feels composed, supportive and more playful than its large battery and 24kg-plus weight suggest. The mixed-wheel layout helps, placing a 29in front wheel over rough ground and a smaller 27.5in rear behind it for easier direction changes.
Shimano’s EP600 motor produces 85Nm. It lacks the sharp punch of the latest Bosch and Avinox systems, but the assistance is predictable and strong enough for steep trail-centre climbs. The 800Wh battery also gives the bike genuine long-ride potential.
The compromises sit below the frame. The RockShox suspension can feel less reactive than the chassis deserves, while the Shimano Deore brakes have enough stopping power but deliver it with a slightly muted initial feel. Neither issue makes the bike poor value; they simply identify where future upgrades would have the most effect.
Subject to availability, with Maxxis Assegai and Minion DHR II tyres already fitted, the Canyon is still the best eMTB under £4,000 for riders wanting the strongest frame, battery and trail package for the money.

Verdict
The Giant SyncDrive Pro 3X combines substantial assistance with a progressive delivery that makes it easy to enjoy. Its strength is the way it builds power on climbs: enough support to maintain momentum, without an abrupt hit dominating the ride.
Its comparatively restrained response may not suit riders chasing the punchiest possible acceleration. For my riding, though, the controlled delivery, straightforward controls and reassuring battery behaviour made a convincing package. The power is there; the way Giant introduces it is the reason to pay attention.
Giant SyncDrive Pro 3X FAQs
How much torque does the SyncDrive Pro 3X produce?
Giant claims a maximum of 100Nm, alongside up to 800W of peak motor power. Those figures describe its stated capability; they don’t mean it delivers maximum assistance throughout a ride.
Is the SyncDrive Pro 3X good for steep climbs?
In my testing on the Stance E+ 1, it provided strong, progressive support. Choosing an easier gear to keep the pedals moving helped on steeper sections, while the motor supplied enough assistance to maintain momentum.
Is it more powerful than Shimano EP6?
It felt more powerful than the EP6-equipped Canyon Spectral:ON CF 7 I recently tested. That is a comparison of riding impressions on different bikes, rather than measured output.
What range can you expect with the 800Wh battery?
This test didn’t establish a full-charge range. I used higher assistance modes and rode plenty of hills without noticing sudden charge drops, but didn’t run the battery flat.
