Re: Marin San Rafael Euro frame-up TSDZ2 powered build

Cripes sake, nuff trouble for a while, I hope! Brakes finally made the PO. Thanks, Tom. Curiously, the pin that was lost was the very pin that I'd installed when I first installed the chain! The brand new chain came with two pins, and unfortunately, I lost one of them while trying to install it. It...

Re: New "TSDZ2 Torque Sensor Central Motor" 52V Battery

The 52V battery is a poor choice for the 15A version of the TDSZ2. ...A little more accurately: a 52v battery is a poor match to the Tongsheng 48v units. Tongsheng has programmed in some voltage limits to their kits. (I understand from second hand sources this is not typical of the market.) Assumin...

Re: New "TSDZ2 Torque Sensor Central Motor"

Mostly, I was thinking that Level 1 on the 48V might be more than she wants and level 1 on the 36V would be a way to start slower. Hearing the comments, I may be overblowing that thought a bit... Yes, and you're leaving out a key factor in the voltage decision: the higher the voltage, the more effi...

Re: New "TSDZ2 Torque Sensor Central Motor"

For those who may be math-challenged, if the new 52v units, with their 4500 RPM top speed, have the same internal reduction gearing as the earlier units (a safe bet), then that means the power assistance will drop off at just over 100 pedal RPM...

Re: Marin San Rafael Euro frame-up TSDZ2 powered build

Took the Marin San Rafael out for some riding yesterday to run some errands. Got ANOTHER flat. This made the fourth flat since new only a week or two ago!

On my two units, a 48v 15A and a 48v 18A, there's no perceptible drag at all. It rides just like it did before I added the motor.

Re: New "TSDZ2 Torque Sensor Central Motor"

Guys, extracting bearings is all about having even tension on either side of the bearing, making any force, directly upwards. One screwdriver on one side will often not move a net fit bearing, however one on either side often makes it feel easy. Never and I mean never tap a bearing onto a shaft by ...

Re: New "TSDZ2 Torque Sensor Central Motor"

Guys, remember the blue gear is toast anyway so just get your hack saw and cut it away so you can get a bearing puller down the backside of the bearing. Chances are that if the bearing is an interference fit ( which I doubt ) the bearing maybe damaged whilst pulling it off so for the cost of a bear...

Re: New "TSDZ2 Metal Gear

RT111- I doubt very much the replacement gears are copper. Copper is an extremely soft & pliable metal. Most likely they are brass. Certainly I did not make such mistake; I was told that they are nearly pure copper. Given that it's to replace a NYLON gear, it's entirely reasonable that nearly p...

Re: New "TSDZ2 Torque Sensor Central Motor"

Taken in context, my remark alluded to the fact that a metal gear will not survive without lubrication. Those thinking of replacing the gear need to think quite carefully about this. There's not an oil sump on these motors, any of them, so the grease can go anywhere except where its wanted. That's ...

Re: New "TSDZ2 Torque Sensor Central Motor"

The thing about these types of gears is that they will survive without lubrication. That is after all their main advantage. Yet all the other motor builders with synthetic gears do spec a lubricant and they do require lubrication. Are we thinking TS doesn't? Yes, TS does specify lubrication be used...

Re: Manufacturers not promoting DIY middrives w/torque assis

Torque measuring assistance in general, and the TSDZ2 in particular, is for people who don't want a moped that claims it's a bicycle. Seems to me that those who sneer at the "anemic power" of such systems are trapped in their own ignorance and perhaps dogma. I love my 48v 15A rated Tongshe...
