It sounds like you are unfamiliar with that, so I’ll say again:
I've used the technology for over 10 years. It's VOIP. You don't realize you are talking about VOIP. That technology also has gateways into the normal phone system.

What you are talking about here is VOIP "voice over IP/internet".
Phones now can switch between a voice connection and an internet connection (
which is VOIP).
The only way you get this switching feature is with a cell-phone plan.
This is a hybrid between standard cell-phone service and VOIP, It's relatively new. Phones needed to be set-up to support it (that is, it isn't available on every phone).

You are talking about needing
two devices. Both of which can make phone calls but, but the cycle computer cell-phone
needs another cell phone to work.
Your idea is to have the cycle computer act like an iPhone (
that's one plan) and use WiFi to connect
another iPhone to use as a hotspot (
that's a second plan).
The only way you avoid two plains (sort of) is to have a pure VOIP service like Skype running on the cycle computer.

What you are talking about is VOIP.
=================================================
You are talking about either of two things:
- A cycle computer that is a cellphone. This would require a plan. This would generally be a second plan to the first one people already have for a regular cell phone. This is kind of silly.
- A cycle computer that can use pure VOIP, which would require a second device. This would not require a second plan but it requires the second device and a data connection (which you won't get in as many places). This is kind of silly too.
