I assembled an e-bike for a neighbor last week (X-Treme Rubicon 48). He has heart issues and broke a leg earlier in the year. He hasn't really even been able to walk for exercise. The bike has been life-changing for him, mentally and physically. The hardest part for him is simply getting on & off the bike - it's very heavy and cumbersome.
I'd consider one in the future if I had health issues that prevented me from riding a pedal bike. Thank god I don't need one.
