@tk Interesting to me that the more modern-looking one seems to be a fixed sidecar (effectively a tricycle for handling purposes) while the older one appears to allow the bicycle to lean into corners at least a little. It does surprise me that they put the attachment points in the second one at different heights. I'd expect that to cause wheel scrub if the bike or the road is tilted. I wonder how it actually handles?
Someone should invent an electric vehicle that doesn't weigh 2+ tons, isn't a danger to everything and everyone around it, is easy to operate on narrow city streets, and is small enough to easily store.
Oh wait, we already have those! :blobfoxgooglymlem:
