On the LCD3, the temperature refers to a sensor inside the display. The LCD3 settings do allow for it to read a remote number from the controller, but the controller has to have the capability to read and send it. I've owned a number of KT controllers too, maybe five different types, and none...

The KT controller's throttle input looks for a voltage between .8V and 4.2V, As you go toward 4 V, you approach full throttle. Most throttle controls use a hall sensor chip which reads a rotating magnet to control the voltage, The advantage is that there are no moving electrical parts like...

C5 parameter sets the current. Values between 3 and 10 10 for 100% of rated current 03 for 50% of rated current See display manual for in-between values, I always seem to get 100-120 watts in PAS level 1 on 36V and C5=10, Half a dozen installs.

I think you only need a 15A KT controller to run a mobility chair. Use a 24V controller too. The nice thing about KT units is that if you buy the right KT display, you can further limit the current to 7A to keep the speed manageable, The motor and electronics are trivial. What will take your...

I've put 980 miles on my TSDZ2 since I installed it in late 2022. The VLDC5 froze on me when I tried to zero the distance, but mistakenly had the odometer numbers showing. I pressed the center button too long and it must have gone into some factory diagnostic mode and jammed. There's a factory...

I believe the TSDZ2 circuit board has the inputs for the throttle, but for the 6-wire display, they leave the wires off. Why maintain two versions of the circuit board? Check this link, and you may wish to look at your circuit board to see if the three inputs are there. The main one being the...

The general procedure is to tear down the battery to the point where the BMS and its ribbon cable are exposed. You don't have to tear off all the shrink wrap covering the cell array, The low voltage at the output is only because the BMS has isolated the cells from the output. You probably have...

Did some research A 6902RS bearing to replace the gasket on the non-drive side, . Some people put in two on the non-drive. It's not clear to me how to add a bearing on the chain gear side in less than two minutes though. unless it replaces the shaft seal. I guess that's what you mean, though...

Unless those two other controllers were sensorless controllers, this shows that that the Hall sensors in the motor work. Could be a broken wire in the controller cable, or blown circuit in the controller. I've had the Err 03 when I spliced a 9 pin plug onto a motor cable, and had one of the...

Wouldn't a torque washer be more appropriate than those washers in the link, providing the dropouts were the right size.

What are TSDZ2B mid drive prices in the UK, compared to hub motors? From a power comparison, they are not as strong as a 500W hubmotor, but should compare to a Swytch. I can get a TSDZ2B kit in the USA for less than a hubmotor in a wheel plus controller/display. I really dislike filing dropouts...

After 600 miles, and three mid drive installs, I believe I finally learned how to ride my TSDZ2. I keep it in Eco mode, rear gear in one of the middle gears, and spin the pedals faster than I normally do, Plenty of power, even if the motor is off. Climbs better too. Before, I was riding it like...

I set the OSF/embrusa Eco settings for power and torque mode to 70 and 50, Hybrid mode is default, Everything else is their "proven" settings. This lets my wife pedal her TSDZ2 along at 10-11 mph, about the same speed as her cadence sensor bike. I did the same for my TSDZ2 bike. Both happy now.

The KT LCD certainly is big and a target for cracked screens, I've broken two when the bikes fell, and it was probably just the shock transferred up the handlebars and thru the plastic mount, as the LCD never touched the ground. And I also cracked a creen the first time I fliiped a bike upside...

Very nice, I saved a copy for myself. By the way, the diagram doesn't show three bosses on the cover ring, used for mounting screws on the cover. One of them would hit the chainstay and prevented me from setting the motor in the best position.. I filed it down.

Oh well. My wife thought OSF hybrid mode was too powerful, so I set it in EMTB mode on the road, and she dawdled along at 8-10 mph, and said she was in Sport level assist most of the time. I spent the rest of the daylight hours, and it was a pleasant afternoon, sitting outside with my PC...

I didn't think my wife would like the bike, but she's a good sport and put a hour's ride on it. She said it was a lot of work. I know she hates it. I saw there was a hybrid mode available, easily reached with VLDC5. Put it in Turbo level and hit the lights button 4 times. Wow, this was quite...

I installed the TSDZ2B last week on a older 26" Giant RIncon. The unit went in fairly easy. One of the pedals was frozen into the old arm and couldn't be re-used. The chain stays hit one of the screws holding the motor cover. I filed down the boss for the screw to get full clearance. Also some...

Tx is an output and Rx is an input, Connecting two TX's together is a problem if one tried to go high while the other wants to pull low. but usually there are resistors in place within the IC or outside of it that keep them from blowing up, As long as you don't connect the two leads that carry...

The reason is that the charge protection circuits are bypassed. It was a combo of errors and oversights, but I once connected a 48V charger to the output of a 36V battery. Luckily, I alwsys check any charginging packs and unplug them before I go to bed, and I found this one around midnite...
