Re: Hardware temperature control tsdz2

Yes, I cut one strip of 10 mm thick thermo pad (100 x 30 x 10 mm), stretched it around the stator and put the cover in place. I tested it only once, climbed on one hill (altitude difference about 160 m). ambient temperature was about 15 degrees Celsius. Temperature climbed from 15 to about 30 degree...

Tsdz2 design flaw

Hi! Having nothing to do in this days of self-isolation, I decided to make a spring service on my TSDZ2 bike that I assembled last year. So I realized that there is about 2 mm play in my front sprocket, way too wobbly for my taste and with only 500 km under my wheels Removing the front sprocket, I r...

Re: Hardware temperature control tsdz2

Hi! I added a termometer (for a bit of "steam-punk" flair, i put the classic capillary thermometer, without a single electronic component :-) I put the thermometer probe in the cavity behind the plastic cover and added some thermo pad to keep the pressure agains the housing. Not directly on the stat...

Re: Hardware temperature control tsdz2

I put 10 mm thick pad on the same position, on The Dahon that I am building for my wife. I cut one strip of 10 mm thick metrial (100 x 300 mm), found out that when you strech it and wrap around the stator, it behaves like a mixture of clay and rubber, so It shrinks back with a bit of delay, just eno...

Re: New "TSDZ2 Torque Sensor Central Motor"

Regarding the crank offset, I was also looking at it, found in my garage one old left crank with zero offset. Then I discussed it with the bike mechanic, he told me that he can convert it to the right crank (basically drill out the left thread and put a new bushing with the right threading). Then I ...

Re: Easy Pedling on electric Bicycle (Geared or Gearless)

It is difficult to objectively estimate the drag from the motor or even the clutch because human body is constantly adapting to new conditions. I call it the "electric legs" syndrom. When I started riding my TSDZ2 kit bike, I felt that there was no significant drag in the drivetrain. About a week la...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi! Yesterday I did my best to install the motor on a Trek Fx2 but I was not able to install the back bolt attachment. There is no room for it between the bike chain stays and the bolt support. Is there any alternative? Potential issues if I run the motor without it? I would be careful with that - ...

TSDZ2 Sprag clutch

Hi! I have my TS about 2,5 months now and only about 360 km on the clock. It is running fine, but I noticed about 1mm play on the chainring already, and also some play on the crank. So it seems like it is time for new sprag clutch order... I can order new "Big Gear" from PswPower, but it will most p...

Re: How to plan how much battery I need for a TSDZ2?

Hi! I have TSDZ2 48V / 750W. From your parameters (1500m 8-9% incline), your home is about 120 - 135 m above the city level. I have similar situation, although somewhat lower (about 60 m above the city level). And I am a bit heavier than you. I have a LG brand 48V battery in 13s4p configuration, 12....

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi! Newbie alert :D I also put a 750W TSDZ2 on my city bike and so far I am quite happy with it. For now I am using the standard firmware, maybe I will update it during the winter pause. I found on the web that quite a few people are complaining that it is not powerful enough and that 8Fun is better...
