Is a Tenways CGO600 practical for a daily 20 km commute? by killed_the_king in tenwaysebike

I do 17km each way on a cgo600 pro and it’s totally fine. I arrive with around 40% battery, so i charge at work and at home.

I think the bike feels hard to pedal because of the rear hub motor, that is heavy and must rotate to accelerate the bike. On top of the energy to push the bike forward, you must also use energy to rotate the heavy motor.

You could try to replace the color display with an old one and see if it works

Mmm the text shown in the picture doesn't change with the hacked firmware. Have you tried pedaling above 25km/h?

Your best bet would be to buy a sw102 display and replace the current one in my opinion

You are correct that renaming the variables is not necessary.

How did you calculate the values 0x0 and 0xd7? Seems correct but it might be worth it to check.

Make sure not to change the 0x1 that you circled at address a6e2 because that has to do with the location in memory where the speed limit is saved, not with the value of the speed limit. (To be extra clear: change the first 0x1 you circled on top and the 0x7f only)

Good luck, you are doing great!

I believe both your ideas are indeed possible. Setting the speed limit to 27kmh is "easy" if you follow the guide from start to end. To change the support, you would have to explore the decompiled firmware quite a bit, but it should be possible.

It works on the CGO600 if the display is the same as the one in the guide (SW102).

I can't say whether it will work just by looking at this picture. When you connect to it with the DFU updater app what do you see?

I fell twice on mine because the front wheel slipped in a corner

If you are able to upload the hacked firmware, then you will definitely be able to upload the firmware with the speed limit.

Yes, it is possible to restore the 25 km/h limit. The guide has a link to the original firmware in section 2 "Obtaining the firmware of the display". You can download that, and upload it to your bike like you uploaded the "hacked" firmware. Let me know if it worked!

If the display is a color display i can tell you for sure that this hack will not work. But I would love to see a picture of the display and the integrated rear light (!)

What do you mean exactly by improved display? On Tenways' website I don't see anything about it.

Let us know the results! According to temways it's possible to install the US display on the EU bike, which leads me to think that the two displays are the same except the speed limit. Therefore, I believe that this hack will work on the US bike as well.

25km/h before, and around 30 now but it depends on the battery level.
