We know you have a working LCD, controller, throttle and trunk cable. We know you still have problems with the pedal sensor and the speed sensor. Follow these steps: 1. remove the battery. 2. undo the 4 screws, remove the cover of the controller compartment which has the battery connector on...

the main thing in troubleshooting anything is to keep the number of variables as small as possible. Let's sort out the pedal sensor first and leave the speed sensor disconnected for the moment.

Fixing things is easier if you and I are on the same page. Let's fix first the pedal sensor, when that works, then sort out the speed sensor. Leave the speed sensor unplugged. I need you to follow the suggested steps. There is a logic in what I suggested.

Let's fix first the pedal sensor. Check that the magnet disc still has all its magnets and it turns correctly together with the cranks. Check that the LED on the pedal sensor flashes correctly when you turn the cranks. If the problem persists, can you email support@wooshbikes.co.uk some closeup...

Andy has gone home. I usually do out of hours support when the office is closed. Do take one step at a time, it's easier to master the wiring that way.

lastly, connect the brake sensors. On the controller side, you have two identical grey/black 2-pin JST connectors:

Connecting the speed sensor: If you manage to get the pedal sensor to work, the next step is to connect the speed sensor. Follow the motor cable to the controller box. The speed sensor is connected to a 3-pin male JST connector which needs to be connected to this connector: speed sensor...

6-pin connector: 3 large pins are the phase wires, 3 small pins are connected to the internal speed sensor. Leave the speed sensor unplugged for now. Follow the pedal sensor cable from the bottom bracket to the controller box. It has 3-pin female connector. On the controller side, the...

If you could post pictures here, I may be able to help. First, check the motor cable connector. Does it have 3 pins or 6 or 9 pins? Next, does your bike have a spoke magnet on the rear wheel? Once I know that, I can tell you which wires go where.

Send Andy a picture and mark the wires you need to know, he'll tell you.

The error codes are on page 11 of the KM529 LCD manual. Download it here: https://wooshbikes.co.uk/manuals/KM-529-LCD-Display.pdf You initially reported error 23. 23 Motor Abnormality. Inspect if motor phrase is well-connected; Inspect if lines are well-connected between motor phrases and...

please do come back and let us know. I would like to know how their torque sensor works.

you can send Andy what you want him to test to rule out some possible causes. It won't take him long to check the parts you send in and can help you pinpoint the fault.

that's a good review.

I experimented with the last implementation. For the toseven implementation, I found the picture you posted previously from toseven leaflet. The picture was too fuzzy to make out the details but it looks like they replaced simply the Hall sensor in the TSDZ2 design with a strain gauge. There is...

you are right on this, I mentioned it in this thread but not on my website because I have not got the item in stock yet. I can also agree with this. The critical part in the software is the torque sensor. I experimented a lot with strain gauges and the problem with it is the small range of...

something I read when looking at the designs of DVMs. All DVMs have high precision shunt resistors (1% for common garden variety, 0.1% and better for high count variety, Vishay makes 0.01%), but you can only use calibration function with an external board of reference resistors on some models...

I spent some time yesterday reading up about calibration of domestic digital multitesters. It turns out that very few brands would publish data on the acuracy or precision of their DVMs. The best I found is the Uni-Trend UT181A. I looked also at the OWON OW18E which has bluetooth so handy for...

The E MOVEMENT THUNDER V4.2 is a fat bike, 28kgs heavy to pedal if the power fails. Other than that, it looks like built with standard Chinese parts so repairs outside the warranty shouldn't be a problem. Battery is 48V 10AH, good enough for your short commute. The MULTITRACKS X1B is a similar...

Code 30 is communication error. Unplug the throttle to see if the error goes away. Please email support@wooshbikes.co.uk - Andy will help you fix it.
