    New "TSDZ2 Torque Sensor Central Motor"

    That's not the good 48v version, I tend to ignore 36v ;-)

    If you've no idea what you're doing, don't review things... In all honesty complete and utter none-sense like this: "250 Watt maximaal is het voor ons" Bullshit, 250 Watt NOMINAL is the max in the Netherlands. It has nothing to do with max power. Also, when you gut the max amps (aka your watt...

    Hardware temperature control tsdz2

    Cannot say for sure, ofcoarse, but if the cooling would be much better I fear it indeed wouldn't have passed EN15194 certification. Mostly because that electromotor is actually pretty good stuff!

    New "TSDZ2 Torque Sensor Central Motor"

    I wonder why you're saying this? Like: The money isn't thát bad and the time... well... for each their own hobby I guess. In terms of panelties: - Having a third roller-bearing non-drive side, does mean the tolerances are much more important (In comparison to cardridge bearings + bearing glue)...

    Breaking: Unknown, depends on the tolerances within your personal parts The rubbing is irrelevant, you should put it into your maintenance schedule to check the low-friction material for wear and replace accordingly

    New "TSDZ2 Torque Sensor Central Motor"

    I found the money isn't that much, it's mostly the time it takes getting everything ready to have things machined. Basically many other parts will likely fail before those needle bearings. --- On another note: Can anyone send me drafts and pictures of the TSDZ2 main clutch bearing and/or has...

    New "TSDZ2 Torque Sensor Central Motor"

    Interesting design, i'm willing to put some time into this as a second prototype, if you're willing to forward me the CAD drawing :) In general I like how the thick Boss endpiece, limits sideways play while also providing a more rigid connection between the torque-sensor and axle. It also...

    New "TSDZ2 Torque Sensor Central Motor"

    The point was, that while those initial drawings where great, some people where reacting like there was something new in those initial drawings. It's important to note it's a rehash, otherwise we again get a flood of new people, adding a lot of repeated "blablabla" helping absolutely no one...

    New "TSDZ2 Torque Sensor Central Motor"

    Most of these issues have been known for a few years by now. The issues is not lack of knowhow, the problem is bascially that no one bothered to actually work on getting that shitty axle fixed. The issues are there, in these threads, the fixes are there... Basically all that's needed is that...

    TSDZ2 No-Grove Axle Project (Custom Made)

    I hope next week or the week after, but we all know how the december months can be :( I'm also very interested how a H7 fit works out, mostly if it's a "smooth enough" fit, but nothing ventured, nothing gained :)

    TSDZ2 No-Grove Axle Project (Custom Made)

    The goal is to maybe do a small-batch production run. I'm not going to design things on order or something. Nor do I've the design experience to even alter it to ISIS spline... Update: - Also got the production report today, seems to be okey, though it has to be remeasured ofc.

    TSDZ2 No-Grove Axle Project (Custom Made)

    Thanks, so some notes on the differences people will see between these: - You will notice it's lacking the groves, which are common known failure points. Instead of groves, this would rely on bearing glue (loctite) and MUCH (10x) tighter tolerances. - You will notices it's not black, I've...

    TSDZ2 / 860C shopping list reality check

    It does not have a "better" clutch, it has a "different" clutch. This distinction is significant, as far known, its still a cheaply made clutch with a lot of play and with the same low max-torque rating as the original one. I also want to add to this, that motor has terrible tolerances...

    CYC PHOTON

    Tests are run, from the top of my head, at around 20c somewhere. So at 0C, I see no reason any 250w continues rated motor cannot do 300w for continued and/or 500w for a reasonable long peak time at that temperature.

    TSDZ2 No-Grove Axle Project (Custom Made)

    Update 21-11-2022: A package has just arrived. Next would be installation testing, hardness testing and tolerance testing. Besides going over the report from manufacturing to spot any irregularities.

    By law, EVERY EN15194 motor is required to overheat if used above 250w continuesly. Period. The testing method is literally referenced in EN15194. You can throw all sorts of things at it, but that's the law and the regulation and we all have to deal with that The only solution is to prevent it...

    There are a number of users here and even reviewers and youtubers of the TSDZ2 in the USA. Even so: almost all of those Bosch and Brose motors also comply to the same rules. Even the USA sold ones. Which basically means: The vast majority of emtb's in the USA. Yes there is, i've explained how...

    New "TSDZ2 Torque Sensor Central Motor"

    Motor bearings can't really get (much) tordial load, so don't worry about those. Poor tolerances and lack of enough-bearings in the axle is likely your problem. Replace with good enduro bearings and also replace the two seals with bearings as well. (including, or even: more importantly, the...

    Hardware temperature control tsdz2

    The is open for water ingress on the backside and none of the contacts anywhere are actually potted. Lithium battery connections of, lets say, 50v and moisture... that's not going to be a pretty sight... The fact the motorunit itself is brushless is not very relevant tbh. Ask yourself: "Why is...

    TSDZ2 / 860C shopping list reality check

    +1 on the extra and better (enduro) bearings. Besides the clutch bearings they are relatively cheap as well :) Also: - Thermal sensor (this is really non-optional, do it!) - Think about grabbing the right speedsensor to also be able to plug in your lights into the ebike motor

    I never said the product makes a lot of sense in the USA, it's pretty clearly targeted for EU (CA?) Ebikes... However, even EN15194 compliant motors (bosch, tongsheng, some bafangs) are also populair in the US ebike market. So appearently you're wrong and people still buy EN15194 compliant...

    TSDZ2 120mm Axle Broke for the 2nd time on my Fatbike

    I'm currently working on getting the axles remade with hardened steel, without circlip grooves and with H7 tolerances. Sadly enough, it will only be the normal-size axle for now. If it works out, I will throw out a kickstart/buying-action for it and if that's populair enough I'll look into also...
