I do NOT envy your situation here.

There are plenty of times when rear brake is all you need. Slippery times. Rocky, steep downhill runs. An emergency situation with sand all over the road. I guess snow. Anything too slippery to be using the front brake.

I still don’t understand how this bike is supposed to go down a very steep hill with loose rocks in dirt if you can’t use only the rear brake.

Now, are you definitely sure it wasn’t doing the proper ABS thing and letting the back wheel roll at the point just before lockup? I know in the snow ABS often feels like no brakes at all in cars. It’ll roll that wheel at the point just before lockup across snow/ice and because the friction is so low, it feels basically like your brakes failed.

Also, is it possible this ABS is wrong? Like that the logic is incorrect in the computer? If it does what you’re saying it seems like it’s wrong.

Finally, does this bike have a “dirt mode” or other mode where these electronics are turned off?
