The battery doesn’t look removable. My preference would be a modular bike, although I can see the advantage here because you can’t tell off-hand that it’s an e-bike.
Don’t park your e-bike near or in your house. YouTube has video of one sending wisps of smoke a minute before it erupts (big-time) with fire.
A news story covers a dozen suffocated from fire fumes among parked e-bikes in India.
Some ebike batteries are removable.
We live in a fairly hilly area. My wife has had knee surgery and, while she loves to cycle, couldn’t make the uphill climbs. Her ebike has let her cycle again.
Yes, you can go without pedaling. Yes, you can go too fast. You can go too fast in your car, too. It does take a little getting used to, but it is fun and it lets you get exercise without overdoing it.
The batteries are removable - they go so many miles before they are replaced - my e bike is two years old and has gotten heavy usage (our family owns five) - and not one of us has had to change out the battery yet.
