On the 3 motors I have sitting here, its water damage that has been the failure on all 3. Odd failures though as all 3 are from different overall problems, but has ended up with the controller damaged. Its odd as the only way in for the water is through the silicon where the leads go through or the seal around the main crank ( plastic cover ) which then gets into the main motor and controller compartment via the torque sensor wire cutout ( unfortunately you cannot silicon it in as it has to allow the springs on the torque sensor to work properly ).

In the last motor I installed ( still running fine ) I packed entirely the void behind the cable entry point, behind the plastic cover with waterproof thick grease to stop water being forced up against silicon of the cables, as I suspect its here its getting in. I'm not sure how to beef up the seal around the crank other than making an additional seal on the outside of the case which many engines in adverse conditions do have this outer steel cover as close as the crank as possible and then an inner seal dealing with just water.
I've put electrical tape all around the cover over the cables and then where the cables come out I've packed it with silicon. So fingers crossed. When I clean my bike I take the motor out. Maybe I should put silicon up against the crank seal too? Another thing I am considering is making a mudflap out of old inner tube and hanging it off my front fender?
Raid the garden shed for old plastic plant pots. They have the right curvature for extending your mudguards and are light weight. Otherwise, ice cream tub lids can work if you heat them with a heat gun to give them a curve.

Did any of you combine the TSDZ2 with the drive system Sram EX1 used in the best Bosch motorized electric bikes (Cube, Hibike)? Sram EX1 dedicated to electric bikes with a special thicker chain and 8-row 11-48T cassette, gears can be changed even under load: https://www.sram.com/en/sram/mountain/s ... ncy&page=1.
The system consists of :
Cassettes + chain + derailleur + shifter + [cranks from Bosch engine]. My question is whether it is possible to use SRAM EX1 with a standard 42T crank with TSDZ2, or better to replace it with a dedicated one? Do you know any dedicated crank minimum 42T?

As far as I know, this is a standard size chain, only a bit stronger.
So it should work with this motor without any problems.

Is there any way in the software to turn down/off the extra motor time when you stop pedalling?

I assumed this was how long it took for the “timeout” to occur from it sensing any rotation anymore, but I’d love that option too if feasible. It would make not shifting under load without a gear sensor much easier.

Has anyone noticed a price increase on TSDZ2 kits? Seems like they've gone up $50-$60 USD since December 2019?

SW102 new firmware release

The previous firmware version on SW102 had a problematic issue where the configurations and other settings were not being saved and I was able, finally, to correct it.

Changelog:
- corrected issue on SW102 display were the configurations and other settings were not being saved
- changed SW102 display enter configuration button, to be different from button to change screen

Download the new version here: https://github.com/OpenSource-EBike-fir ... D/releases

There is apparently a “new and improved” 2020 version. Maybe that’s why it’s more expensive?

Where did you see something about a new 2020 version?

Does anyone know how much of a difference is there between having a 48V battery vs a 52V battery with the TSDZ2 with OSF? Is the increased voltage noticeable for the user?

I noticed when the battery is about 50% the max speed is a bit lower and you have to pedal a bit harder to maintain a 40km/h speed, for example. I got around that by modifying assist number 9 to 5.0x from 3.0. So i use that when the battery is lower and seems to work. The motor power is around 400-500W, it drains the battery a bit faster, but i can maintain higher top speed.

I got chased by some dogs when i had about 45V left in my battery. I barely escaped them, they chased me about 1km. I wasn't getting the top speed i was usually getting when i have more charge, closer to 50V or over 50V.

So i'm just curious if anyone has experince with both 48V and 52V batteries?

Looks like it is smaller. I just bought one so I will not be getting the new version any time soon. Will be nice to wait and see how it does. If it is a lot better and compatible with the open source firmware and old displays I will upgrade when my motor dies and who knows by then maybe another version will be out.

Looking at that picture, I would say the latest motors I received from PSWPower are already the new motors... and I see no changes at all.

And the picture seems to mistake us, because the "new" motor it is at a smaller scale and gives the impression it is smaller but it is just the same size.

I am pessimist right now... maybe it is just marketing, maybe there was some small changes but maybe to improve the production on their side, price optimization, etc but nothing really relevant for final user like a lighter motor, more power, smaller, etc.

I have installed BBS02 systems on two different recumbent trikes. I use the Bafang Programming software to tune these up, and make backups of the configurations. Works very well.

But I am spreading my wings and am about to install a TSDZ2 system with the open source firmware v19 and the 850c display (modified) on another trike, and I am wondering if there is software to save configurations that I specify using the 850c display? Or like the Bafang programming software, does this exist to set the TSDZ2 config values. And make backup config files, restore older configs, etc?

It seems the discussions I've read are about flashing firmware and not specific to simply setting configuration values.

Thanks in advance

I am not aware of any software to do that. Maybe if you open the display and can hook up to the swim line then you can dump the whole memory or just the addresses that store the config but you’d have to do this manually and by yourself.

I don't think there are 'new' motors coming. There was a very recent change to the motor housing, and other small changes as well... Also TS says they are not making changes, but did say something about a custom change for a customer order. Anyway, that's the info I have. I could be ill advised, but I don't think so... I am having my associate check as well, who has better communication with TS than me, to double down on this.

P.S. - also, I wouldn't judge too much by the pictures. For example, on the backside of the chain ring houses, they still show a raised ridge, that was taken away 2 motor housing changes ago... over a year ago...

Edit/Update: ok, no new motor/housing changes, but there are some controller changes. Not sure if this is for a single large order or for all new units. Finding the specifics of any hardware and/or software changes to the controller. Will report when I know more

2nd update: They had made some minor changes to the controller for a Euro customer, but this is nothing major for anyone, and not even an improvement.

Basically no new motors or controller etc...

Well, no changes is also good news as others look to my ebike and they like it, they say the motor is small and I am comparing with others, I always use less battery than others and I heavier, 105 kgs while others weight like 80 kgs. Today I did 2000 meters acummulated and 70kms using 350Wh and other coleague did stop at the 50kms when his 400Wh battery was empty (he weights 85 kgs and I weight 20kgs more).

Also I see other ebikes with like only 3 or 5 assist levels, where users has not control at all and they don't even know /system don't show the battery power being used!! No human power value, limited to 25km/h and 250W unless the users pay a lot but they don't do because of warranty, etc -- Our OpenSource firmware and TSDZ2 make excelent ebikes!!
Also I am seing some brands with ebikes with batteries of 500W that weights the same as mine, with a 500W battery, so, the weight of the motor + battery seems similar to the ones used on commercial ebikes.

No doubt, the firmware really is what makes this motor so great. Thanks for your efforts!

Has anyone found a dished/offset 52T gear? My chainline is quite bad, even with the gear at the inner side of the spider, and I'd like to move it a bit inwards.

Does anyone have a list if the dished gear rings that are available?

Also waiting to hear if we are getting close to flashing the boot loader on the SW102 without cutting it open.

This bearing dont works. "Jumps" easy.Very low torque capacity.

Be carefull.

As my chainline is soooo out of straight I thought of the Alfine SG-S7001-11 (11 gears, 409% from lowest to highest gear, ebike approved). Any comments on this before I buy (the whole set is almost 450€ with gear lever and stuff ...)

Looks nice. I haven't been paying attention to IGH much lately. It seems many are ebike rated now... A bit stronger internally.

There will be some 50T chain rings for TSDZ with 10mm offset in maybe a month, FYI, but nothing bigger than the 42T 10mm offset for now...
