I doubt I think the new batteries different voltage and they would be much larger then the advanced as that is a light weight bike I think

No mention of larger battery and only 90Nm
800W peak though. It will be interesting to see what sort of range this gets. I assume they must be pretty confident in it's ability to release it with a 560wh battery. Perhaps the Yamaha 48V system has given some efficiency gains.No mention of larger battery and only 90Nm
90nm is loadsNo mention of larger battery and only 90Nm
why would you need more? I'm 100kg and my current bike max is 55nm. People are obsessed with numbers after dji when in reality you won't ever use the max. If you did, your range would be very small

560wh is the energy it won’t be more because it’s 48v, it may work a bit better at the top and bottom of the charge than the old but I doubt it, it that is the spec then I’m out I need more power and bigger batteries to keep up with my mates new s-works

Depends how you ride I did 75 miles and 17000 feet in 3 days on a trip last week I was on my current Reign in turbo everything max and struggling to keep up with my friend non his specialised90nm is loads

Your misunderstanding. 48v makes the whole drivetrain a lot more efficient. Less energy lost to heat etc. So a 48v 560wh driver train will go further then a 36v 560wh drivetrain. Just because both are 560wh, it doesn't mean all the battery makes it to the motor and provides propulsion. Lots of lost in inefficiencies560wh is the energy it won’t be more because it’s 48v, it may work a bit better at the top and bottom of the charge than the old but I doubt it, it that is the spec then I’m out I need more power and bigger batteries to keep up with my mates new s-works

I agree higher voltage means lower current but the efficiency gains will be minimal unless you have cables that are super small or very long. It’s not going to make a 560 battery are good as an 800 lol
It's not meant to. Hence the large extender you can have. It will how ever go significantly further than a 36v 600wh battery. More likely closer to 700wh.
So you can have 840wh 48v drivetrain with the new giant. That will be like an existing 1000wh battery. It makes a lot of sense and gives you options . No one ebike suits everyone though. Every bike has a compromise

22.3 kg in the leaked advert
If there is also going to be a 840WH battery for the new Reign I think it's an odd choice to spec if it with the 560WH out of the box.
It's just the 560 (plus range extender if you have it) from what I can tell. Don't think there are other options at this point at least.

The battery / frame strategy is very awkward with the downtube being so chunky.
Steeper prices, SL type battery strategy with full fat aesthethics and no large capacity battery being offered is starting to make a lot of compromises.
I'm not sure what kind of strategy Giant are aiming for, but since 2025 Giant is officialy out of the full power/full capacity battery eMTB market which should be a very significant sales segment for them. Maybe they just don't care about their own brand anymore and are just looking after OE sales and selling a few high margin bikes under their name.
I think people need to not focus on 560wh. You will be surprised at how long the new tech in the giant lasts. I actually struggle see anyone wanting the bigger/heavier 840wh battery. It would last far longer than any other ebike battery out there. Too long really. Why have the extra weight
Everyone wants big power, big batteries. (OK not everyone, but most people want big batteries. 560Wh looks like a step back, especially on full power ebike). 48v is decent but in no way going to compensate for lower capacity.
Of my riding group, no one is looking for smaller batteries. In fact everyone wants big batteries and fast charging, good looking ebikes.
Source: Talking to bike brands, the mix of smaller batteries to bigger battery sales is massively in favour of big batteries, if a bike can take both.
22.1 kg in medium
It's really down to the individual rider though isn't it? My group of riding buddies are all saying that they'd take smaller batteries and less power/torque if it meant less weight. My dilemma would be whether the new Reign will be enough of a weight saving over existing one. My bike weighs a ton with a coil shock and 800wh battery, Schwalbe radials etc on it but I'm not sure how much I'd save with the new one by the time I'd beefed up the tyres and exploding X2 on it! If I could save five kilos, that'd be really significant but I'll need to wait and see just how much of a change there actually is in reality.
Yes definitely its individual, for sure.
If *most* people would take smaller batteries, less power/torque and less weight, then SL type ebikes would be way more popular than they are (in fact the category is almost dead as it is).
Yeah, I totally get that and the bike that has tempted me the most recently has been the Orbea Rise LT (which speaks volumes about what I'm looking for in an ebike). I think the blurring of the line between SL bikes and lighter, full power bikes has been the death knell of SL. I think most people have a kind of ebike FOMO (and I include myself in this to some extent) and err on the side of power/battery size over weight saving. I just know that every time I descend, I wish I was riding my analogue enduro bike but then when I'm climbing I'm glad that I'm on my eeb but I spend most of my time riding in the lower three assistance levels, even when I'm climbing. I accept that I might be a weirdo, outlier though (along with the folks I usually ride with)!
Well, there must be many weirdos as I too feel the same... Lightest bike for going down and enough battery to go up and have a decent day out in the trails. For me the sweet spot is around 600 Wh on an 85Nm bike that I never ride in Turbo. Once that battery is empty, which almost never happens in my case, then my body has had enough for the day... I reckon there might be that once in a blue moon LOOOONG ride to occur, but Range Extender is good for that and I don't carry too much battery for 95% of the normal rides. My 2 cents

I’m on the opposite end of the spectrum I want the biggest battery I can get (2 of them) and most power I can get in a reasonable budget (can’t afford new sworks) we ride in high power up steep roads to get to even steeper trails back down, repeat till the battery is low, grab a sandwich and change batteries at the car then do it again, I know over a dozen people that do the same my mate had a year old rise and nought a specialised just for the battery change ability
This echoes my thinking pretty much exactly. I initially dismissed the new Reign but I'm now quite curious about it. The decider would be just how much lighter it'd be than my current bike.Well, there must be many weirdos as I too feel the same...

I'm honestly not having a go here but it is ironic that you live in Leicestershire (according to your profile) and I live in Scotland, you'd expect our preferences to be the other way round eh?
Yes, 48v is indeed a good choice. Technically speaking the current standard of 36 ish volts should have been abandoned long ago.

I live I’m the middle of everything but I’m not close to anything I have to drive an hour or 2 to get somewhere decent to ride, need to do a Scotland trip.I'm honestly not having a go here but it is ironic that you live in Leicestershire (according to your profile) and I live in Scotland, you'd expect our preferences to be the other way round eh?
The point here is that when you ride these super high-power motors, they draw a huge amount of current from the battery, which means more heat and more stress on the cells. Higher voltage becomes especially important as the motor and your rides get more powerful.
Ok, you could go for a 120 Nm/1200 W motor, but that performance won’t last that long because of the heating and the battery will drain very quickly. In fact, some DJI owners (Amflow) are requesting lower torque and power settings because of the motor’s high energy consumption.
For those looking for super-long rides, they will need to use an extender (840Wh) or a second battery. And that’s something that DJI can’t offer: DJI is 800Wh/36V fixed setup...no extender and no second battery option. This new Reign provides more options at that point.

Come on Giant, its nearly 2026, surely we can do better then this.

My current Reign E+1 ( XL Almost 27kg with Cushcore and gravity tyres ) is pretty nice. Run down to limp mode on the 625 Watt hour once - that was a 50km+ day in Derby TAS. I don't mess around - Tour or mid mode mainly - I like to actually feel like I'm riding and am pretty fit. I find with proper hard riding and full gas DH style riding, jumps and hard terrain I'm pretty well knackered before my bike runs out of steam. 560Watt ,newer tech, and a significant weight drop ( if true ) might bring this thing in on par or even better realistically.
