Re: 120v aluminum/cromo TIG welding on bike frames - possible?

Agreed, and for many ebike or experimental projects it would be just fine. In my case it is availability in small quantities and I rarely need a full 20 ft. length of the same diameter material. Aircraft Spruce sells 4130 and will cut any length from 6" to 8' (if using UPS) and will do so quick...

Re: 120v aluminum/cromo TIG welding on bike frames - possible?

I can't help with the choice of a modern machine as mine is a Miller Dialarc from the late 1980's. Not the best for what the OP wants to do and also large and heavy being transformer based. I will, however add my vote to those who suggested brazing with an OA torch. I have built many frames using th...

Re: MPF Drive 5.1 info needed

Thanks Bob for the replies. It continues to work, and I can't see that any functions are missing from the display.
So I shall do as you suggest and "run it till it drops". Then build an adapter to install one of the bottom bracket mounted DIY motors.

Re: MPF Drive 5.1 info needed

Thanks Angrybob for the response. I will only charge thru the OEM charger for now. 5 pins on battery and mount, only 4 on the charger. I opened up the mount to see where the mystery wires originated, here is what I found- IMG_0209 2.jpeg IMG_0240 2.jpeg IMG_0239 2.jpeg It does look like the smaller ...

Re: MPF Drive 5.1 info needed

Thanks for the reply, I was wondering if I had the only one of these in existence. We have been riding the bike and do like how the motor is working, the feel is much like the early Bosch powered bikes I have ridden. Yes, heavy and probably over-engineered as you say. After some investigation, in ad...

MPF Drive 5.1 info needed

Greetings all. I just purchased a cargo bike with this motor installed. While it seems to be working fine for now, I would like to source a larger battery for it than the tired 12ah one currently there. However, there is virtually ...zero... information on line about this motor. I did find a German ...

Re: New "TSDZ2 Torque Sensor Central Motor"

Shame. Didn't look at the screw it self. Not that I could have read it without magnifying glasses anyway. ;) Thanks! I'm not using the supplied cranks, as I had to shorten mine because of the 20" rims I use in my former 26" bike. Could be that the Tongsheng taper is not exactly the same a...

Re: New "TSDZ2 Torque Sensor Central Motor"

[quote=izeman post_id=1558454 time=1590327125 user_id=20975] That's why I asked for the correct torque the first time, but haven't received an answer yet. I can't find a number. My understanding is that these bolts should be torqued to 38-42nm (or 28-31 ft lb.). The taper should be free of burrs and...

Re: New "TSDZ2 Torque Sensor Central Motor"

The hardest thing to duplicate would be the splines, but they are short, few in number and stand proud of the shaft itself so should be less difficult than they might be. IMO, just controlling the seat diameters so the result is closer to a press fit would suffice for many people. I now checked the...

Re: Nihola Cargo Trike Rebuild - N380 IGH-TSDZ2

The reason that I had to dent the stay was that I also had to tap and face the bottom bracket. When tightening the big nut to hold it in the BB, the motor "cocked" enough to touch and so would probably loosen in service. A bit of measuring showed the faces were not parallel, and after faci...

Re: Nihola Cargo Trike Rebuild - N380 IGH-TSDZ2

Welcome to the club. I just did the same conversion and find the motor quite a good match for this bike. We have several bikes with the BBS02 and I originally intended to use another of those, but after riding the Nihola in stock/pedal only mode for a bit decided that the "moped" feature o...

Re: New "TSDZ2 Torque Sensor Central Motor"

The bike is a Nihola "dog bike", which is their standard family model with a door in the box for pet access. The motor mounts very nicely on this bike, a tadpole bakfiets-style trike with somewhat improved steering over the more typical "swivel-the-box" type. Alleged weight is 72...

Re: New "TSDZ2 Torque Sensor Central Motor"

Greetings all from Northern California. New guy here with some BBS02 experience but the TSDZ2 is new to me. I have installed one with OSF (6.3) on a cargo trike. Easy install which I plan to document for the GitHub pages later this weekend. However, it is exhibiting some erratic behavior. I have att...
