My very good friend: it's been 2 months since you were here and we discovered that the ebike battery wouldn't fit your frame. You went away knowing that a couple of rivnuts would do the trick. Only now, a week before we try again to convert your bike, do you decide to fit the rivnuts.
And then when you struggle to drill the holes, you tell me that you've tried a centre punch to no avail. Only you hadn't, had you? All you'd done was stick tape on the frame thinking that would help you drill into painted steel. So go and buy a punch - preferably one of the sprung ones, and give that a go.
And you spelled 'pedal' 'peddle'. That's the worst faux pas of all 🙂
