Hi,
Compiling my notes on the bike here to help others decide if this is the right bike for them and help others with setup. Please add additional details/corrections/links as responses and I will update this first post.
Rob's video:
Weight:
2022 E+2 = 25.9kg out of the box (tubes no pedals), tubeless will get this down to 25.5kg.
Estimated weights based on other users and websites:
E+3 = 26.5
E+1 = 25.5
E+0 = 25
Best places to lose weight on the bike:
Stock wheels are 2.3kg, while mid-range aluminium ones are typically 2kg or less
On the lower spec models (+3,+2), swapping to 11s GX (or better) can save over 300g
Some members of the forum have experimented with custom battery locks and case, dropping considerable weight at the risk of voiding warranty.
Battery weights:
Geometry:
The bike is much lower and slacker than advertised, and than it's competitors. There seems to be some variation in BB height even across the same model, but some users have found their BB around 33cm even in High position.
Highly recommend running the bike in High mode with 2.6 tyres. Ensure you have (much) less than 30% sag and consider switching to 150 or 155mm cranks. You could also overfork the bike with a 180/190mm fork.
Cranks:
Miranda delta or Hope with M15 crankbolt
Example:
The bike can not be run in full 29er mode with decent tyres:
Range:
My range for a 75kg rider in coldish conditions with highest possible assistance:
Other points:
Bearings: (thanks pwiles1968)
APP and software updates:
Issues:

Battery weights:
- 625Wh: 3.95kg
- 750Wh: 4.3kg
- 800Wh: 4.4kg

- Low flip chip: 32.5mm BB height, 63 head angle
- High flip chip: 33.4mm BB height, 63.8 head angle

Cranks:
Miranda delta or Hope with M15 crankbolt
Example:
The bike can not be run in full 29er mode with decent tyres:
- 27.5x2.8 fits fine in rear
- 29x2.3 does not fit in rear
Range:
My range for a 75kg rider in coldish conditions with highest possible assistance:
- 625Wh: 30-35km, 900-1000m climbing, 1h40 to 2hrs
- 750Wh: 35-40km, 1400-1500m climbing, ~2hrs
- 800Wh: TBD.
Other points:
- Headset is an odd standard, effectively the lower cup is for 1.8" forks, but some models use a reducer bearing to fit standard 1.5" forks. Quoted as a ZS66 for a 1,5" fork at the bottom, and ZS49 or ZS44 at the top. Better to get your local giant shop to work on it in my opinion and not much choice in aftermarket products.
- The frame uses SRAM UDH standard for derailleurs, and as such is compatible with SRAM's highest end "transmission" drivetrain.
- On an M frame, water bottle will most likely be limited to 500ml
- Recent app update allows for torque, launch and assist level configuration in every mode.
Bearings: (thanks pwiles1968)
APP and software updates:
- The Giant app allows to see detailed battery percentages, perform software updates and tune the motor at each level along 3 variables (Torque, Launch, percentage assist).
- Some users report issues after some updates, such as issues charging batteries in the bike. It is possible to access the app without performing the mandatory update as follows, thanks @DOCTOR EBIKES : "enter the application by putting the phone in airplane mode, once this is done, the application asks you to connect the bluetooth and you have to do it like this but always in airplane mode, by doing so you can enter your ebike without the Mandatory need to update your ebike"
Issues:
- The main reported issue is frame cracks on the 2022 models on the top of the down tube.
- Some members reported issues with charging batteries to 100%, either a very slow process (which appears to go away after 10 charges when new) or the charging getting interrupted (most likely a charger issue). My shop implied that they have had a handful of faulty 4a chargers.
- Previous versions of the reign have had issues with water affecting various electronics, up until now the 2022+ bikes seem to be doing ok with water ingress.
