The motor and battery are the same on both bikes, so hardly an issue unique to KTM.
The battery had a software recognition fault, and was replaced within the space of a week, as was the motor. I'm not the only person/forum member to have suffered bearing failure, and a quick Google search will reveal the same of the battery.
I'm only teasing with the following SW.
You also have to remember that I actually use my bike off road.
In fact, my total mixed off road, and road mileage for this year will by close to 3,000 miles come the end of December. I'm guessing at 80% off road, and 20% percent on road. Not a bad figure for mainly weekend and evening playing.
Not sure what you mean about the frame bolts. I've only ever read about Haibikes loosing rear suspension linkage bolts. Indeed, the only thing holding your own bolts in are cable ties.
But as said before, that is just down to a poor maintenance regime by some owners. (not counting you in that, as you still have your bolts) The rear hub etc, didn't exactly last long on the Haibike either. I suspect that given my annual mileage, my bike has actually been far more reliable, and also required less/ no upgrades.
Ref the e-Race, the only photo that I can currently find, is this one.
