Which Giant Bikes Share The Same Housing Motor As The Yamaha PW - ST, Would Anyone Have Any Model Numbers Etc

Good question, @INVISIBLE - and it ties in neatly with what you've been digging into lately with your Haibike.

Giant's eMTB motors are badged as Giant SyncDrive, but they're built by Yamaha - so mechanically they share the same DNA as the Yamaha PW series. The current generation is the SyncDrive Pro3 (100Nm), with older bikes using the Pro2 (85Nm) or Sport (75Nm) variants.

Here are the Giant bikes using Yamaha-derived SyncDrive motors: Full-suspension trail/enduro:

• Giant Stance E+ - SyncDrive Pro3 (current 2027 model, 100Nm) • Giant Trance X Advanced E+ - SyncDrive Pro2/Pro3 depending on year

• Giant Reign E+ - SyncDrive Pro2 (enduro platform) Hardtail:

• Giant Fathom E+ - SyncDrive Pro2 (85Nm, current 2026 model verified) • Giant Talon E+ - SyncDrive Sport (75Nm)

One important distinction: the SyncDrive motors use Yamaha's internal architecture but with Giant's own firmware, display ecosystem (RideControl/EnergyPak) and motor bracket. So while the core motor shares lineage with the PW-ST you're running on your Haibike, the mounting interface, connectors and coding are not cross-compatible - which, given your recent threads about motor swaps and bracket modifications, is worth flagging.

If you're researching which bikes share the closest physical motor housing to the PW-ST specifically, Yamaha's own-brand bikes (like the YDX-MORO) and brands like Fantic and GasGas are actually closer matches than Giant, since they run unmodified Yamaha hardware with standard PW interfaces.

What's the end goal - sourcing a part, or looking at a donor bike for something?

I Wanted To Fit A Giant Motor Inc Controller , As Long As It Fits My Haibike Alltrail 5

I Wanted To Fit A Giant Motor Inc Controller , As Long As It Fits My Haibike Alltrail 5

This is where the plan hits a wall, @INVISIBLE - and it's an important one.

The SyncDrive motors in Giant bikes aren't physically compatible with your AllTrail's motor bay. But there's a bigger issue underneath that: your AllTrail 5 runs a Bosch Performance Line CX Gen 5 (120Nm) - not a Yamaha motor. So a Giant SyncDrive (Yamaha-derived) wouldn't be swapping like-for-like in any sense; it'd be a completely different motor ecosystem going into a Bosch-spec frame.

The motor mounting, bottom bracket interface, connector pinout, and controller coding are all specific to Bosch on your bike. A Giant SyncDrive unit - even though it shares Yamaha DNA - uses Giant's own bracket, connectors and firmware ecosystem. It won't drop into a Bosch mount.

If you want to stay within Yamaha hardware for your AllTrail, that's going to be a much more involved conversion starting at the frame mount level - which ties into what you've been exploring in your other threads about PW-ST bracket modifications.

What's the actual goal here? If it's more torque/power, a different Bosch motor (like sourcing a Gen 5 donor unit) is a more realistic path than crossing ecosystems entirely. If it's specifically the Yamaha feel or interface you're after, that's a bigger job and worth understanding the scope of before sourcing anything.

My HAIBIKE Alltrail 5 Uses The Yamaha Series ST Motor, So What Other Motors Can I Fit In The Same Housing?

My HAIBIKE Alltrail 5 Uses The Yamaha Series ST Motor, So What Other Motors Can I Fit In The Same Housing?

Good news - you've actually already got the right motor for swapping within the Yamaha PW family. Your AllTrail 5 runs the PW-ST, and based on your other threads, you've been looking at fitting a PW-S2 or PW-X2 into the same housing.

Here's what I can confirm about Yamaha PW motor compatibility within the same frame: Motors that share the PW-ST mounting interface:

• PW-S2 - same housing footprint, but note there's a difference in BB axle length (the S2 uses a narrower spindle), so your crank/chainline setup would need checking

• PW-X2 - again compatible at the motor mount level, though the bracket geometry can vary slightly by bike brand • PW-X3 - Yamaha's current-gen 85Nm unit; worth investigating for your application

The complication: Even when the motor housing fits, the controller is paired to the motor and display system. Swapping a bare motor without the matching controller and display is rarely straightforward - which ties directly into what you've been digging into in your bracket modification threads.

I want to be straight with you though: the exact bracket-to-bracket dimensional compatibility between PW variants on your specific AllTrail 5 frame is something I can't confirm with certainty without seeing the frame spec. Your other thread - "Anyone Modified The Bracket" - is probably the best place to get firsthand experience from riders who've actually done this swap.

What specific motor are you targeting? That'll help narrow down whether it's a clean fit or a modification job.

Would A Giant Bike X2SC0 Motor Fit My PW ST Model Bike

Would A Giant Bike X2SC0 Motor Fit My PW ST Model Bike

Short answer: no, @INVISIBLE - a Giant SyncDrive motor won't fit your PW-ST housing. I'm not familiar with the specific code "X2SC0" - it may be a part number printed on the motor casing or from a listing, but I can't verify what it refers to without more info. What I can tell you with confidence is the broader picture:

Giant's SyncDrive motors are built on Yamaha architecture but use Giant's own motor bracket, mounting interface and connector system. Even though the core internals share Yamaha DNA, the physical housing and mounting geometry are specific to Giant's frame design - they're not a drop-in replacement for a standard Yamaha PW mounting.

Your AllTrail 5 uses the PW-ST mounting interface. The motors that share that bracket footprint are the other motors in Yamaha's own PW lineup - PW-X2, PW-X3, PW-S2 - not Giant's rebadged versions.

If you've got "X2SC0" printed on a motor or part, it's worth sharing a photo - if it's a Yamaha part number rather than a Giant one, that changes things and we can look at it properly. Your threads on bracket modifications are honestly the best place to dig into the dimensional detail with people who've actually pulled these motors out.
