That’s a fukkload of watts. As pubes said, the Bafangs are pretty much quiet. Mine was 500 watts and dangerous as hell. I nearly flipped it at the lights once. I’m really regretting selling it now. Great for commuting but cadence-sensed power is no good off-road. Is that one torque-sensed?

Yeah, it’s torque sensed and has a sort of different BB setup than the others I saw like Bafang. Also has a throttle option. Seemed cool but the noise is a deal breaker!
The Bafangs have a throttle too. Really good for Getting the hole shot at the lights.
Ok. I am e-bike kit dithering again. There is a guy in my neighborhood that rides around on a longtail with a TSDZ2 bolted on, I stalked him out on google and emailed him, and he actually wrote me back with a bunch of info about the Open Source Firmware and configuring/ordering a kit.
Seems to me the OSF might still have a bug or two but that people are pretty happy with it. I’ve got my Big Dummy pretty well kitted out asides from the motor so I think a bolt-on kit makes a lot of sense. Main thing is to figure out what battery to get, as I feel like I have relatively low expectations for speed. My current average speed on the Big Dummy is about 10mph give or take for conditions, and getting that into the 12-15mph seems modest but might actually require a lot of juice for someone my size.
My main question to the group here is, does anyone have any experience with the kits in freezing temps? I saw some manual for the TSDZ2 that mentions you shouldn’t use it below -5C. I have no idea where I’m going to be living 18-24 months from now, and the Dummy would be a pretty badass winter sled with or without electricity. But -5C really isn’t that cold shartmo… I’d expect a pretty precipitous drop in range, but is there actual risk of damaging these motors?
COMPLETELY anecdotal but I see kit bashed ebikes riding around Boston winters, and I’m POSITIVE food delivery folks use em year round in NYC so I’m sure the -5c isn’t super hard. Sub 0f who knows. Probably fine if stored indoors at both ends of a commute.

Nice thing I guess is that the TSDZ2 should come off the bike relatively easily in the winter if that’s what needs to happen
Fyi: not motor, but battery longevity on our STePS is noticeably shorter in cold weather, even with battery stored inside (exception if we’re actively out for the day at parks etc).

I’ve been wondering about this. Are you gonna try one of those neoprene battery sleeves?
The E6100 Bullitt’s advertised range is 110mi on a full charge using eco mode. I think I got around 70 last charge and it hasn’t been ridden above 40 degrees yet.
Edit: JK. I have the smaller battery, which is 55mi range. Guess I’m actually doing ok.

I haven’t tried the sleeve yet but considering it.
Think the best I’ve gotten on ECO is ~90km. Maaaaaybe 95km. But generally with mixed use (ECO + NORM) i charge somewhere around 80km.
Now that it’s cold I’m charging around 65km.

people use eco mode?

Raises hand…
I do when I just need a lil boost up hills
i usually keep it in sport or c h u r b o
I use Eco almost exclusively in lower gears, unless up long hills with a big load.
My sp(w)owse on the other hand, is big gear + BOOST to go everywhere.
Wonder what that does to the battery
All boost all the time, which is 400% assist up to 650 W on my science bike, except if pedestrians are nearby. Then it’s down to 0% or 100% depending on the situation.
drains it much faster. i can tell you that.
my primary e-cargo experience is work owned bullitts. i never needed that much range so i would always set that thing to wumbo. the e-cargo trike we briefly owned was fucking awful, had an underpowered hub, small battery, and was sketchy as fuck at or over 15mph
Batteries don’t like to be charged. Do your part.

i refuse
I should have said:
Batteries don’t like to remain charged.

I cruise comfortable at 14 on eco. No need for any more than that unless I’m really in a hurry.
