@futurebird it was terrifying being in Seattle a couple of weeks ago: the Lime ebike rentals are SO FAST and SO HEAVY. In the UK assistance is capped at 25km/h (15.5mph), still fast but not close to the speeds you can get on ebikes in the US, it seems.
Especially dangerous for rental schemes where riders are not experienced cyclists, don't know local laws and don't wear helmets.
