    New "TSDZ2 Torque Sensor Central Motor"

    Greetings all. My wife's cargo trike is still at OSF 6.3. It's buggy, but we have learned to live with it. Usually works fine, sometimes we have to restart 5-6 times to avoid a whine/growl. Once we get it running quietly it will behave all day. Recently it has added the annoying habit of the...

    New "TSDZ2 Torque Sensor Central Motor"

    We have a Nihola cargo trike with the TSDZ2 and a Nexus 8 speed IGH. No problems with that combination whatsoever in approx 650km so far. Total weight of rider/bike/dog is about 135kg, only paved roads/trails so far and we do take care to not shift under load. The Alfine 8 speed hub is...

    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...

    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...

    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.

    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- It does look like the smaller wires pass thru the mount from the battery...

    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...

    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...

    New "TSDZ2 Torque Sensor Central Motor"

    Yes, it takes a magnifying glass to read (unless your wife just bought herself an iPhone 11 pro -amazing camera!) and I had originally assumed it was just the makers logo. The tapers should be the same as that is an industry standard. (There have been variations over the years but things appear...

    New "TSDZ2 Torque Sensor Central Motor"

    CNC equipment is not needed for a one-off of the round parts of the axle, and I believe the end tapers and spacing of the splines can be handled on a mill with a collet indexer. The actual profile of the splines may require a custom cutter however. All doable if one is determined enough, I will...

    New "TSDZ2 Torque Sensor Central Motor"

    Hello izeman and others. Regarding the broken shafts, I believe the steel used is less of a problem than the snap ring groves, and the fact that the crank mounting bolt holes are deeper than they need to be, at least on some of them. I am most concerned about the wobble/clunk and the wear it is...

    New "TSDZ2 Torque Sensor Central Motor"

    Back to the loose and or wobbling crank axle problems, and thanks to safeaschuck for posting the detailed pics (way) above. I have TSDZ2 on my wife's cargo bike, and other than some initialization problems seemingly fixed, if not totally eliminated, by a firmware upgrade (stellar customer...

    Andrew707 wrote: I took everything apart and measured TSDZ2 spindle and bottom bracket diameter. Turns out TSDZ2 is around 33.1mm while my bottom bracket inner diameter is 33.5mm. That's why I get this play when pedalling. Any ideas on how to secure it properly? Did anyone have issues like me...

    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 facing...

    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 of the...

    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# before adding...

    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...
