Hi giant people I've already dropped to 34t from the pointless 36t standard but I'm thinking 32t as it's cheaper to do that than change cassette I run 11-36 deore cassettes as there pennies and I'm yet to find any reason why u would need a 50t on an ebike ? Anybody fitted 32t any problems?
32t chainring ?

well mine came with a 32t standard and it seems fine, from my point of view top speed is that last thing on my mind I just want to get to to top easily, fun part is coming down steep stuff where you don't even need to pedal never mind wonder about gear ratios

2019 has 1x11 (11-46T and 36T).

Any significant different with 36T->32T, less battery wear ?
More range and easier climbing... I am enjoying it a lot. However I ended up with 34t and 11-42t cassette, great combo!

So I got still 36 but on the rear 10-51T Deore, so Your 42/34 = 1,24 factory... in my 51/36 = 1,42, but honesly factory 46/36 and max support can manage any mountain

I just went 32t in the front, no issues so far. I'm running 11-42 11 speed in the rear as the cassettes are much cheaper. The 34T I had before was perfectly fine but felt having the ability to climb stepper at higher cadence would be nice.
Currently both my Giants are running 32T CR.
The Trance19e+ is a Shimano 10 speed, 32CR 11-42CS, 165mm cranks on 27.5 wheels.
The TranceXe+ is a Shimamo 12 speed, 32CR 10-45CS, 160mm cranks on 29 wheels.
The average speed on my daily trail ride ranges between 8 and 12 Mph depending on conditions.
Kentucky is hilly, not mountainous.
I'd say the gearing is dam near perfect for the riding I do. I'd also say that the OEM 36CR is completely useless as OP already stated. Its a mystery to me how the spec champs (Gaint), could miss this element so badly.
I prefer the performance of the 10 speed over the 12.
I've run a 30T chainring but find it unnecessary around the trails I ride.

Hi yeah I agree mines 1x10 deore / slx and if I'm honest the deore shifter is better than the slx ? I think 10 speed should be e bike standard I just run 11-36 deore cassettes there cheap as and I'm yet to find anything I can get up with the 36 why the hell do they fit 50t cassettes on e bikes there pointless we had this discussion the other day when buying an e bike I think suspension,frame, motor are important in that order wheels brakes and tyres can be changed cheaply that's why I just bought the trance 3 I was going to fit a dvo fork but the suntour aion that's on it great I've upgraded the damper under warranty so now have h/s comp l/s comp and rebound then skf seal kit and it's easily as good as a revelation or pike ?

My bike is a 9spd so I got one of those Zitto 11-40T cassettes off Aliexpress. Works a treat.Mine is a fathom from 2019 that came with 11-36 and GS derrailleur so 42 is the max I can use without upgrading to sgs

Don't forget that the smaller you go on your chainring the more torque you put on your chain and your suspension. Also your chain has to go through a tighter radius which results in more wear on your chain.
The other consequence of running smaller sprockets at each end is less teeth in contact with the chain at any one time. This is especially critical on the rear where running a smaller chainring means more time spent on the smaller sprockets on the rear and due to the small chain contact area make it more likely to jump teeth

What bike? I'm curious what commuter bikes have for gearing compared to a serious off road bike?
I have a 2023 reign e+3 .
It came with 36t praxis chainring and 51- 10 cassette.
I removed three chain links and was able to remove the 36t ring and put either praxis 34t or praxis 32t without removing spider or crank arm .
The 32 tooth ring is a bit more difficult to install without removing spider or cramarm .
But it works .

I went down from the ridiculous 36t OEM chainring to a 34 just to gain more ground clearance. I hate the thought of decking the chainring out as all that force is then being transferred to the bearings in the motor. 34 gives better clearance but when the time comes to replace my transmission I'll be dropping down to a 32t. I'm not worried about smacking the plastic motor housing on a rock or log and as the assistance cuts out around 15mph anyway I'm not concerned about losing top end speed either (nearly all my riding is techy off-road though).
How much more ground clearance do you get on 2 teeth?
Enough that the lowest point on the bike changes from being the chainring to being the plastic motor surround.
I have a 2023 Reign e+3 with a 800 wh battery.
I recently did 80 km ride one in april 2023 with a 32 tooth chainring and the same ride 80 km with a 34 tooth chainring
The power consumption respectively was
6.3 wh/km for 32 tooth
7.6 wh/km for 34 tooth
This represent a 20 % increase in electrical use when using a slightly larger chanring.
While it probably doesn't make a difference on the flats it really saves power when gaining elevation. Total Range difference on this ride, a 800 wh battery would yield about 21 km more range using a smaller 32 tootj chain ring
