A can of gas and you can ride off road all day. With an electric dirt bike, maybe an hour. You can buy an extra battery pack (several thousand dollars) and put a gas-powered generator in the back of your truck. Lol. But it still takes longer than an hour to charge the spare. Lolol.
VerticalScope owns a lot of the online powersports sites now. Motorcycle Online, Two Wheel Freak, etc etc. These sites are all tasked to promote electric bikes regardless of the facts. They are also required to squelch all criticism of BMW motorcycles, but that is a different thing. The big advertisers pretty much dictate the content.
Why not attach solar panels to the bike instead of an additional battery?/s
