Don't talk about falling off bikes!
It's a funny thing, but you do get used to it! I hadn't fallen off a push bike since 1964 (and I was 18 and drunk) until I came to ebikes 4 years ago. Since then I've been down 4 times, three on the canal towpath. Just getting the front wheel cross-threaded on a ridge of mud running in the direction of travel did it each time, and fortunately I seem to bounce quite well.
The other time was a bit silly, and I must tell the story - it contains lots of shouldn't do's!
My wife and I had been out for lunch on the bikes, (no booze!), and were coming up the hill on the pavement. (I know, shouldn't, but it was a deserted 3pm and the pavement is 4 metres wide!). The hill is steep and my wife, riding her old Raleigh Misty was tired. I gave her some electric assistance by putting my hand on her back and giving the Currie full welly. (I know, shouldn't, but we are old and daft!).
But! wife wobbled, handlebars touched, she came under me, I lost balance and fell against her and down we went! She was pinned under her bike, I was sandwiched between hers and mine! My left foot was stuck under the bike, it took some gymnastics to get it out, pull two bikes off my wife, who was laughing hysterically. Not very dignified for a man of 61 and a woman of 57!
The final outcome was a couple of grazes for me, a bruised knee for my wife.
She won't let me help her up hills any more.
