ECO Cycles. As an online retailer of said motor units, giving reviews and comparisons, I would personally take with a pinch of salt.First comparison I have seen between BBS and TSDZ2 motors. (From ECO Cycles website)
Included: Bare TSDZ2 Controller with Battery, Speed Sensor, and Display Connectors
- Any Power Level / Programming is Available Upon Request (24-52v, 10-18a, 250-750w)
Most of the TSDZ2 models that leave the Tongsheng factory are 13a and the same couple models are commonly sold by distributors at multiple different wattage ratings ~ 350w, 500w, 750w. We typically program ours (ourselves) to 15a on the 36v models, 18a on the 48v and 17a on the 52v models - stronger than you can get anywhere else! We would rate the 36v15a @ 500w, and the 48v18a & 52v17a @ 750w - which is a realistic actual power rating for the TSDZ2. The 750w BBS models are rated with a bit of a deflated value, seeing how they peak over 1300w, while the TSDZ2 typically peaks under 1000w.
If correct the differences seem too small to explain your experience.
My TsdZ2 is a 36v (500 W) model and is much better than my Yose power front wheel kit that I know peaks at 500W acording to the display
Yes it does sound like you've been unfortunate in the one you've bought. But at least you've got one motor you're very happy withECO Cycles. As an online retailer of said motor units, giving reviews and comparisons, I would personally take with a pinch of salt.
My experiences are from real world ownership and uses!
The Bafang is in another world compared to the TongSheng
Build quality, power, ease of use, ease of programming, reliability, ease of maintenance etc etc etc..... Make the Bafang a better buy.
Maybe mine is a Friday afternoon duffer? Personally I would not buy another!
Hey SwizzOkay time for a lil' update.
Have just put her on charge for the 1st time since flashing the new firmware.
* Range seems okay. Managed 70 miles
* Can pretty much live with Eco mode for most if not all of the time, although have not yet tackled any 25% grades!
* Super smooth around the 25kph cut off point!
* At 70 miles we found the low battery cut off...not really a negative though...am taking this to mean that the range is at least as good as before and well...70 miles!
* After booting up and setting off, the Speedo reads 0 mph for about a minute before bursting into life.
* Had an issue at around 50 miles where upon activating the lights to illuminate the screen I got an E02 error. I was also waiting at a red traffic light (take that Daily Fail readers!) with brakes on and a foot weighted on the pedal which may have been the cause.
* As mentioned previously, initial take up of drive is a touch aggressive and the assistance in the 3 higher power settings is noticeably weaker than before...but as mentioned, have yet to test again on a steep climb.
* Youngest Dahling Windoze 10 laptop has thrown the towel in, so unable to do the fine tuning yet.
* 60 mile range seems realistic.
* If the take up of drive & higher power settings imperfections can be tuned out then, Wow
* Need to monitor that E02 error - hopefully nothing.
* Universal eBike kit + Firmware from the hacker community = With fine tuning needed, an experience in the Shimano ballpark.
It is pretty good y'know
Hiya Frodo!Hey Swizz
I must have read this thread about 30 times.
I did exactly what you did and kept the same display.
All has worked fine.
so now you have had this in operation for a while now. Are there any recommended settings from the Java tool
I am hoping just to get to something I like and then leave it. No real need to have a 860c display for me right now.
tbh I was so happy that the flashing worked and the motor turned back on, I didn’t read too much into the settings.
the thing I seem to have found is that putting in emtb mode, means that level 1 feels like level 4 and level 3 and 4 don’t seem to feel much different.
It also sets off like a train. Which is both cool and uncool.
I liked that I could do loads of the cycling before and now it feels like I can’t. Previously I got crazy range. 100 miles perhaps. Now
maybe you can post your settings so I can save some time, plugging and unplugging just to cycle around the block.
You could try power mode. I use this and it seems to function like the normal software but with better assist at lower cadence. It is smooth and controllable.
There is a new version of the software out. This has a hybrid mode a combination of torque and cadence modes. I have not tried it yet but intend doing so in the near future,
Think I need to try this! Do you have a link?In case anyone is following this thread a little update!
I made a massive school boy error and had forgotten to change the "street mode power limit" box as it was set to 250W.
Once I changed this OMG, massive difference. I am using hybrid mode and just fiddling with the levels. But changing this the power is amazing when you need it.
Previously I was wondering what the big fuss was about the OSF. Opinions have now changed!
I think it is just a case now of tweaking to find some nice levels.
I have 2 bikes, one with stock and now this with OSF. The OSF will be going on both for sure!
Hey thereThink I need to try this! Do you have a link?
