Shake to undo applies to all text boxes on iOS. But I don't blame you if you didn't know that, I only knew about it from the iPhone OS 3(?) keynote that introduced it!
Go to Settings, scroll to the very top (beyond what shows as the top when you first open it). There's a search field (this is in a lot of other "list" styled interfaces like contacts as well). Type "undo" into the field. It'll bring up the location in settings to disable "shake to undo".
It's under the Accessibility settings if you want to just browse around for it.
navigation/gps? workout app? whats the difference between a workout app on my iphone compared to a dedicated device (e.g. garmin edge) in terms of safety?
You shouldn't be actively using, interacting with, and providing manual input to your device (be it a phone, garmin edge, or anything else) while cycling. An occasional glance at a navigation app (on a screen that is held by something other than your hand - a clip, stand, etc.) is probably fine - but taking your hand off a handlebar long enough to hold a device, and taking your concentration off your path long enough to interact with it, is asking for trouble.
a) the shaking feature turns on even if i don't type anything just by the virtue of the phone being active (shaking can mean 'undo', not just 'undo typing')
b) i have it mounted on a quadlock on my handle bar, no holding whatsoever.
c) i take the risk of asking for trouble while cycling on a cycling path with no other cyclists near me (within, say, 300m). I am not cycling between 2 double decker buses while texting...

You don't know. If you start looking at your screen and you are moving, you are a danger to others. I don't care what happens to you, but I care that you don't hurt others. And you may.
If there is such a great risk doing that, do you not think that sharing the road with a car would be even riskier?
I.e. if there is no trust i can glance at a screen when i am on a cycling path with nobody around without injuring someone else, how can I be trusted while sharing the road with cars/buses/trams?
Well, I actually learnt about it years ago then forgot it. So, not only its impossible to find, it’s also easy to forget because no visual clues remind it.
