I tried it and in my country they’re restricted to 15.5mph so largely did nothing for me as my route is out in the countryside.

I moved to an e-moped (like an electric vespa) and it’s been amazing. About £1k to buy, £80 to insure and albeit restricted to 50mile range the equivalent mpg is something like 400mpg.

Naturally doesn’t work if you need to carry kids or large objects around routinely but has been great for me
