Hi
What a shame your hubby isn't too keen (at the moment), I hear what Sue says that maybe it just isn't for him, but he hasn't tried so how would he know. He's probably feeling a bit self conscious and I fully understand his fear of having another attack but like you say this could happen anywhere anyway. If you do venture out maybe get a GPS, that way if the worst did ever happen you can give an immediate grid reference of where you are to get someone there quickly.
That aside, I can see he's worried about hurting his back. I have had back probs all my life, had two discs removed, spinal fusions and resulting osteoartritis/facet joint wear & tear and I suffer pain. But I love biking and even with pain I still love biking. The best thing I have learnt is to not go too mad too quickly, plan ahead and have the best bike possible.
For me a full suspension was a major leap forward to alleviate back ache, but if that's out your budget, get a suspension seatpost they take the shock instead of your back getting it and make it a softer ride. I rode with one for years before going full suss.
I now swear my sports massage too, this just keeps me tip top. Funnily enough a lot of my pain in recent years has been because of muscle imbalance and tightening of my quads which pulls back out of shape & then goes into spasm, keeping myself freed has been a major way forward.
If he doesn't like the idea of lycra shorts, then get some baggies or 3/4 length baggies like Endura Humvee. They're really popular, have a hidden lycra short inside which pops out and not too expensive (£50 ish).
Be careful with the bike you're getting off your mate if it is wrong fit for hubbie then it could make his back worse & put him off.
How about hiring a bike and seeing how he gets on. they will make sure he has a bike that fits or another thought is take out a demo bike from a bike shop there's more and more available now.
You don't say if you want to road or mountain ride but either way bike fit is still as important.
I hope you manage to encourage your hubbie that biking is fun and tell him from me (and all the doctors I have spoken to about my probs) cycling is one of the best forms of exercise for someone with a bad back and being fit is 100% better for your back than sitting about doing nothing..
Good luck CJ
