Dad has bought himself an e-bike. It's his primary means of transport (not allowed to drive), and as such he cares about the security of it.

Obviously if someone wants to steal it, its just going to happen regardless of how big the lock is. And he wondered about GPS tracking.

I've had a hunt around, and the vast majority of devices seem to be "Vodafone only" 2G units. My understanding was that even VF 2G could be going away soon-ish? Or is that not an issue?

So to summarise, recommend a small GPS tracker suitable for an e-bike. Primary concerns are:

- Longevity of the device in terms of network support (so would assume that means a 3G radio or better) 
- Some sort of easy to use cloud app I can show a 65 year old how to use
- I guess size is important too so that it can be concealed in some manner
