😀🚲I need like a 3D-printed interference checker for the #tsdz2 and #bbs02 #eBikes motors, something that can span over the existing cranks and just center into the bolts, or at least the spindle, to check whether the motor body and stuff was going to collide with the bike frame before I remove the bottom bracket and maybe not get it back together the same after finding that the motor doesn't fit. Also if I didn't have one of each motor here to try, seems like there should be a thing.
Rik @ bikescape.orgMy second TSDZ2 motor burned out this week :( it only had 600 mi on it after about 9 months of use. Hoping I can salvage some of the components & find a Bafang motor to replace it with. Of course this happened in February so I get to take it apart outside in the cold, rain, & snow. Ugh. #bikeTooter #CargoBike #ebike #TSDZ2 #bafang
They are also working on improving safety - they use XT90 power connectors and build their batteries with name-brand cells. I’m realistically hoping to get a couple of years of use from this kit before it dies. https://www.electrifybike.com/products/tsdz2b-osf-upgrade-motor-kit-250-750w #Cetma #EBikeConversion #ebike #CargoBike #Tongsheng #TSDZ2 (2/2)
Any #BikeTooter folks with #Tongsheng #TSDZ2 “Error 30” troubleshooting skills? I’ve been fighting with this for a few weeks. I get the error on three different displays, with two different display cables, and two speed sensors. The motor cuts out after about 30 seconds and the display turns off. All my searches on the many forums point to a failed controller. Is it time to buy another motor? #ebike #Error30
AndresI ordered a #TSDZ2 programming cable (https://cycles.eco/products/tsdz2-motor-firmware-programming-cable-with-6ft-usb-extension). I really don't like the default settings and motor is noisy. After getting the #BBSHD (which either Luna or the prior owners had programmed with fantastic settings) and the #BBS02 (which came with stock settings that were pretty bad, but I reprogrammed with the #bafang programming cable and now it's almost as good as the BBSHD), I've realized that replacing the TSDZ2 firmware is probably going to be a huge difference.
I also just prefer the feeling of the #BBSHD to the #TSDZ2, but this is also some good rationale: https://jonsully.net/blog/ebike-cadence-vs-torque-motor/
If you want to feel like you're always getting a workout and always pushing, you want torque-sensing.
Cadence-sensing lets you choose whether you want a workout or want to rely more (or entirely) on the motor, because you're trying to get somewhere. I appreciate the choice.
(Of course low-quality cadence-sensing systems suck, but so do low-quality torque-sensing..)
@NewNordicNormal @eeen Yeah, I notice my #tsdz2 (with stock firmware - I'm told that the open source firmware fixes this) does that sudden cut-out thing. I really dislike it.
Then again if I were mixing it up with 40mph car traffic, it probably wouldn't matter whether it was sudden or not. I'd get a usb programmer for it and up the cut-off limit to ~30mph.
Bummed that my #Bafang #BBSHD didn't come with a connector to power headlights.. but I've got my #Cetma Margo with a #TSDZ2 that *does* have headlight connectors, & a dynamo hub on the front wheel. So I can move the dynamo hub wheel onto the BBSHD Cetma Largo, & use that for lighting. The TSDZ2 Cetma Margo can switch to using the ebike motor/battery for powering lights.
But seriously, why would you make an ebike motor w/out light connections? (newer BBSHDs now include connectors, I think)
#BBSHD vs #TSDZ2 (ie, cadence-sensing vs torque-sensing ebike pedal-assist, respectively) is interesting. My experience was with Bosch mid-drive motors, which are torque-sensing, so I figured I'd prefer the tsdz2. However, I'm really enjoying the cadence sensing. Basically, I don't want to feel super strong when I pedal at lower speeds, and then suddenly feel like I'm pedaling through mud when I hit the 20mph (or whatever, it's configurable) cut-off. I remember the #Bosch was like that, too.
Biked 10mi on the cargo bike out to Long Island, mostly using the Touring level on the #tsdz2, and didn't even use a single bar on the 48V 12Ah battery. So that's nice. #BikeTooter #ebikes
