The frame of a bicycle is probably a lot lighter, as a sort of triangulated truss - compared to the "solid beam" style of a scooter. Disadvantage is it takes more space.

You don't pedal on an scooter, so the battery needs to be big enough to carry around both you and the larger battery (adding weight). Conversely, e-bikes can assist your pedaling (rather than having to replace it in all cases) so they can be lighter.

A scooter is a flat plate with a steering column adding no strength. A bicycle is two triangle elements of pipes.

I wonder why nobody has done electric rollerblades yet.

I have a 2017 Evelo Quest One that’s wrapping up it’s 6th year now. It’s been almost entirely hassle free besides general maintenance and a battery replacement after ~4 years. It looks like the company replaced it with the Evelo Dash.

There’s lots of good folding electric options right now, but if your budget allows for it, I’d *highly* recommend looking for folders with Gates drives. You will be able to roll and hold the bike folded between your legs without worrying about wiping grease all over your pants(or some unfortunate soul who bumps into it). It’s also one of the few things that lives up to its hype — it’s been entirely maintenance-free over the last ~6years I’ve been riding

i ended up going with the cheapest one that can still carry me around far enough (both ways) comfortably: https://www.amazon.com/HITWAY-Electric-Removable-20-55mile-B... (it was 800 when i purchased, also available under a number of different brand names if you search for things like 'foldable 20 inch fat tire ebike')

every brand's advantages just started blurring together until someone said "it's just going to be stolen anyway..."

with the money i saved by getting a cheaper bike, i bought the most expensive lock, to keep the thing from riding away :)

Brompton is the king of portable folders. The Lectric 3.0 is the king of utility folders.

I have one but it's quite heavy and designed more around cargo, trips to the grocery store etc. I have used to it commute into town to go to the office a few times and it works ok for it, but if I started doing that every day I'd probably buy something more 'commutery'.

I have a rad power bikes 'expand 5'.

there was a much larger variety of these exact kinds during the pandemic, but trying to find one these days is hard, and the used ones have company names that no longer exist

the smaller and lighter they are, the more integrated and specialized parts they have, for which replacements need to come directly from the manufacturer :(

still kind of crazy, the sheer variety of models that are still on youtube videos from just a couple years ago, that are no longer even possible...
