Probably more so because of the bottom bracket mounting and the lack of torque sensing

Torque sensing would be the reason I bought the Ultra. Should also note that I pulled the knobby tires off in favor of pavement tires very early on (my bike is used as a hybrid on-off road). I'm pretty sure that's one of the bigger reasons I hear the Ultra's gears. Again not bad, especially at low speeds/power settings, but at higher speeds while pulling 1000+ watts, they're pretty "noticeable"....

Mine seems more quiet at higher boost and speed. Got to be the nylon gear.

I have a small mp3 player/speaker attached to my battery USB port... all I hear is Rock-n-Roll

I usually have a radio going in the shop, so I get my ration of noise there. Then there's the TV when inside the house (wife likes the noise). So when I'm on my bike, I like to listen to.......NOTHING! No rattles or clanks, no traffic, NOTHING! OK, maybe a little wind noise. -Al

I can only dream of a daily ride like that.. The first 12 or so miles of the Rail_trail I typically ride runs parallel and sandwich'd between two major roadways. There are some sections of sanctuary but they don't last too long moving at 12-15mph. At some points it's close to drowning out the music depending on time of day. There are parks to ride in but they've become boring.I usually have a radio going in the shop, so I get my ration of noise there. Then there's the TV when inside the house (wife likes the noise).

On the plus side a good song can get me pumped.

I like music as much as anybody but I don't understand the constant need when you are out in nature. I'd rather listen to birds instead of the Byrds. It's also make people unaware of others.I usually have a radio going in the shop, so I get my ration of noise there. Then there's the TV when inside the house (wife likes the noise).

Well if you consider 6 lanes of traffic moving at 70mph nature... then we disagree again.

Yeah I agree I have them in 20"X 4" on my Ebike, replacement for those loud nobby tires it came with. I am not doing enough off road to justify the noise they make, so now I hear my hub motor and chain more.
It seems if you want the ultimate in total noise reduction you would have these three things on your Ebike:
1)Gates Belt
2)Speedster style tires
3)Motor with plastic/PEEK gear or the BBSHD

Mine got louder by time. After 2000 km’s it didn’t get anymore louder than that. Going to change the bearings at some point. That will help. Pumping it full of SHC100 grease helps a little bit. Removes maybe 20-30% of the sound and makes the pitch lower.

Metal gears, I imagine ?

I may be wrong so don’t quote me but I’m sure I read somewhere anything after 2017 is metal gears in the Ultramax. I might be getting mixed up

Terry, the G510 and the M620 are pretty much the same motor. Some call them Ultra's, some Ultramax. ALL of the M620's have metal gears. The G510 production is split, with the earliest being supplied with plastic gears (would love to get my hands on one), and the later G510's are metal.

Cool, I couldn’t remember. I have a head like a sieve! Too much information and not enough processing power! Lol

I broke my clutch last summer. I had ordered a new main gear and the clutch from Greenbikekit.com . I was very fortunate ordering both since as you see the broken pawl will chew the teething off the main gear.
The set that GBK is selling is the newer 2020 model. The pawls are thicker hence stronger. You can’t mismatch 2019 or earlier clutch with the newer 2020 main gear. I strongly recommend you have one clutch and one main gear in stock as replacement at all times. These will fail. When is the question...

Great info sharing should any of us need to replace any of these parts. Like you say “when” is the operative word. Will definitely store that info away somewhere in my already overloaded bonce!

I'm on my fourth year and certainly don't baby it and no gear or clutch problems yet. But, I do have spare metal ones on the shelf.Great info sharing should any of us need to replace any of these parts. Like you say “when” is the operative word.

I’d love to see a similar video on the Ultra M620.
