Re: New "TSDZ2 Torque Sensor Central Motor"

I'm starting to adapt the third bike for TSDZ2, of course under Custom firmware. It will be the 2015 Mondraker Summum on 27.5 inch wheels, a downhill bike: Zrzut ekranu 2020-01-23 o 20.05.24.jpeg So far I've made two such constructions for wife and kid: Zrzut ekranu 2020-01-24 o 11.58.22.jpeg Zrzut...

Re: New "TSDZ2 Torque Sensor Central Motor"

"There are ppl who like pedal bike like bikes over here and there, and same goes for motorcycle like bikes." When your legal limit is 750W/ 28mph and many bikes can go 35mph it makes sense that the tires,wheels, brakes and suspension will start to resemble motorcycles. They have to. I own one of eac...

Re: New "TSDZ2 Torque Sensor Central Motor"

With the guide on, it's too tight for the TSDZ2 to slide in and fit the way it should. But I can't remove the guide either because I need the rear derailleur. So, what do I do? Replace the wire with full wire guide from the shifter, then route it above the bb-shell. I did the same thing with mine. ...

Re: New "TSDZ2 Torque Sensor Central Motor"

I have just joined the forum and I am hoping someone can help me with a technical question regarding the TSDS2 mid drive unit. I ordered 3 units from China a while ago and have only just installed the second one now. All three were to be installed in "standard" bikes, all with 7 hub-gears and inter...

Re: New "TSDZ2 Torque Sensor Central Motor"

But here in the US 1500W isn't too much for a bike. The ability to run at 30+mPH is a safety issue when sharing the road with driver who aren't used to bicycle traffic at all. ....... Americans tend to have an MTB background, and Europeans more of a road bike sensibility. I'm sure that colors our e...

Re: New "TSDZ2 Torque Sensor Central Motor"

Retrorockit, BBSHD's are a different beast, there's courses for horses and why you are even trying to compare the two motors is beyond me. I tried a BBS02, nice motor, riding experience as a bicycle was poor to average due to its power assist only with no torque sensing, although after much fiddlin...

Re: New "TSDZ2 Torque Sensor Central Motor"

The only thing that limits the time I can make 1500W on my BBSHD is when the long range 17ah battery power drops off. I can use it any time for as long as I want, but range suffers horribly when I do that. For driveline testing it's full power runs until everything is sorted out. I usually do full p...

Re: New "TSDZ2 Torque Sensor Central Motor"

A TSDZ2 is a capable 350W motor. That is not correct, it can handle up to 1000 watts, It always handle that when my 52V battery is fully charged. It doesn't have the cooling to produce that level of power continuosly. A 454CID Chevy can make 435HP. For about 5 minutes. Hotrodders make 600HP+ for a ...

Re: New "TSDZ2 Torque Sensor Central Motor"

There is another factor that may help you get a suspension fork to work. A softly sprung fork will settle down into the travel when turning and this tightens up the steering geometry. Too soft and it will bottom out. My forks are softly sprung with an added elastomer stuck inside the coils to make i...

Re: New "TSDZ2 Torque Sensor Central Motor"

Metal has a bigger expansion under temperature change than plastic. If the bearing was any bigger (or the gear smaller) the gear would crack when the motor gets hot. Disadvantage is that it will slip when it gets very cold. I think the glue will crack too if it hardens a lot, as it has no expansion...

This can reflect not only the state of wear but the strength ...

Re: New "TSDZ2 Torque Sensor Central Motor"

I can't figure out how these end up being offset so much to the right. Looking at the dimensions diagram, I calculate 69.8mm to the left and 80.2mm to the right when used with a 68mm bottom bracket. This makes only 10.4mm offset to the right. Do both factory cranks arms have equal offset? indeed, t...

I once had the opportunity to ride the Packster 80, but only for about 5 minutes. The Bosch drive s...

Re: New "TSDZ2 Torque Sensor Central Motor"

Can anyone recommend a way of getting my standard 42 tooth front sprocket down to say a 36 tooth and still get a reasonable chain line ? The 42 chainring and a wide range cassette would be the way to get lower speed. It depends on what rear speeds you're running. Older 8-9 speeds require a derailer...
