Folding Bicycle Plastic Wheel Replacement

The plastic rear wheel of my Microbike has broken apart. I would like to repair it. This bike is not in production anymore. It was made in Sweden around the mid 80’s. I have some general ideas of how to approach this but would appreciate any advice for details, feasibility, cost and other methods.

The following are some of the options that I am thinking about:

1. Original parts where can I still find some?

2. Another plastic or steel wheel that allows me to attach the original rear 2spd hub while still using the nylon belt. The speed is changed by back pedaling in a quick jolt action.

3. Steel wheel w/o the original hub but still uses the nylon belt with the original or a new chain ring in the front. Preferably this new hub could be 2 or 3 speed, but single speed is fine too.

4. All steel wheel and metal chains and new steel chain ring possibly with 1, 2 or 3 speed hub.

One of the rubber bellow couplings is ripping apart, is there any compound that can patch it together? I am thinking something like those 70’s as seen on TV commercial that sold a kind of putty that one can use to fix ripped vinyl.

I’ve included some photos for your reference.

Larger photos and other detailed shots at the location below:

I will be cross posting this post in the folding bicycle section too.

Thanks for your advices.

I can't help you but that's a pretty awesome looking belt driven folding bike. Got a picture with someone beside it for scale?

Looks like the pulley on the hub could use the standard for geared hubs three splines. The sprockets look like this and are held on by a circlip. It might be possible to fit the pulley to an all new wheel and keep the belt drive.
