Be careful with the new firmware check this thread for the firmware that works I believe that it's anything below 4.7 I think don't quote me though go on this forum and just also what fimware will work with your bike.hope you figure it out.
Sorry my friend,I haven't checked this account in awhile but the motor is a bosh performance CX and it's a 2018 model I'm not sure of the firmware but I can tell you that I'm not going to let the lbs update my ride.i hope this helps you out.
Sorry for the long wait but I was up north at work for the last month.anyway no it's not an eyesore at all and it's really easy to put on and take off.
Got the badass box 4 and am glad that I don't hit that brick wall when the limiter kicks in.i'm riding a cube reaction race 500 the fastest I got it up to is 28.5 miles an hour but I had to pedal pretty hard to get there,I find 24-25 mph alot easier to maintain comfortably.
