#tsdz2 — Public Fediverse posts

My 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

I 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

Here's what the #Tongsheng #TSDZ2 install ends up looking like on my #Cetma #Margo #CargoBike. I haven't cleaned up the zip ties yet because the battery is only temporary (I'm going to get a smaller one that fits better).

Instead of the standard anchor bracket, I screwed a chain tensioner into that anchor bolt hole (https://cycles.eco/collections/tsdz2-accessories-parts/products/chain-guide-for-tsdz2?variant=) because eccentric bottom bracket + chainstay. There's some foam protecting the frame in case the motor moves.

Rode around town testing the Tongsheng motor on the Cetma cargo bike. Did great tackling hills I would never ride without a motor. It was a chilly 28F but nice and sunny. #cargobike #tongsheng #tsdz2 #ebike #BikeTooter #Provincetown

Tons of progress today on the Tongsheng motor install on the Cetma cargo bike. Tuned the eccentric bottom bracket for better clearance of the motor, zip tied the speed sensor, and figured out which side of the chain tensioner the chain goes on! Put the cranks and pedals on and plugged everything together. Test rides were great fun (even though it started raining). #cargobike #ebike #BikeTooter #Tongsheng #TSDZ2
