Recently got a kit from Eco cycles, have maybe 100 miles on it. Got the brass gear pre-installed as that seemed to be the major issue. Pretty sure I'm already over heating the thing, but that and many other issues are not really preventing me from using the motor.
One odd issue I can't seem to find any reference to while searching this massive thread, I'm having lots of noise while NOT under power. While running it's a pretty consistent buzzing, as soon as you come off power it sounds like a coffee can full of bolts. At first I thought it was the chain jumping off, have the narrow wide ring now and pretty sure it's not that.
Certainly seems like it's the large clutch bearing disengaging, I've never heard a one way bearing make noise like that though. I pulled the spider to change the chainring, only thing wrong was a stripped bolt straight from Eco cycles. Nothing else seemed to be exploding so I put it back together. I ordered all the bearings so I can rebuild it if I have to, but also need to get around on the bike.
Eco cycles has been pretty much useless with support so any help would be appreciated.
Let me first say that I got 12k miles off of my first tsdz2 kit that I bought from Eco-Ebikes, so my product did last. I used it as a daily commuter for almost two years. I had to replace the original motor at around 6k miles once because of something that was partially my own fault, and I chose to replace the kit when I burned out the replacement motor 6k miles later. These are the issues I experienced, none of them was a "deal" killer, but it was far from ideal. The support was not great, and I was constantly being told the issues in number 1 was related to a magnet.
1. Every time I would keep the charger past the time it was charged my bike would not provide power for 10 to 15 minutes during the start of my ride. It was very inconvenient when I was trying to ride home. After trial and error, I found if I under-charged it or immediately removed the charger that my bike would provide power immediately. I replaced the motor, the power supply, I even had several different displays (SW102, 800C), thatI could repeat it on each display. This makes me think that it was related to the controller, the only part I didn't replace.
2. I eventually replaced my SW102 display with a C5, and the battery would not go past 80% when fully charged. Funny enough, the issue from number 1 went away, and overcharging never became an issue again. When I asked support told me that this was normal because of battery degradation. I explained to them that when my iPhone gets older than a year or two it still charges to 100% despite degradation.
3. The white pin that connects the motor to the controller had a lot of glue on it, that they said was factory installed. I was never able to easily pull it apart as you see in the blue gear replacement videos on youtube. When I was servicing my blue gear and adding more grease, I would just pull the motor out and rest it on something with the white pin still connected and service my blue gear. This was ok until the motor fell and the tiny cables broke apart from it. I bring this up because this was my fault, and I learned that you could use a hair drier to loosen it up and pulled it apart. I replaced the motor with one I found on PSWPower (a great site with great service BTW). The bike ran fine for another 6k mile.
After the second motor overheated and demagnetized itself, I decided to just purchase a new kit from Eonarau. It was a 48V with a C5 display. I still have my original battery, purchased from Eco-EBIKE. Since then problems 1,2, and 3 have completely gone away, I even successfully tested my older 800C and C5 display, and those work perfectly well. This leaves me to deduce that it was something wrong with the controller in the original kit that they sold me. I can even remove the little white clip when servicing the blue gear.
In the future, I think I would only order bare components from them if I needed them in a hurry and it was in stock in the US. All other things I will order from PSWPower.
