Im just another user like yourself. ive been riding mine for nearly a year now.
Ive experienced every possible unpleasant experience you could have on an electric bicycle and 95% can be avoided by simply purchasing a second battery.
Like yourself ive experienced riding home peddling like mad to keep above 10mph . ive also experienced the bike having a flat battery and having to push the bike home because peddling is far too difficult when theres no power at all.
Running the batteries low is also not good for the batteries.
The simplest solution is a second battery .
I ride on my bike and then disconnect the battery ive just used and connect the fresh fully charged one.
This way I can still put the alarm on whilst I take the other battery and charge it.
The extra confidence of carrying a fully charged spare makes these vehicles a very fun and pleasant experience.
I carry mine in a backpack and after a week of doing this I now don’t even notice i’m carrying it.
The extra pockets of the backpack also come in very useful.
