I have been riding this electric bike for 6 years now.
The battery has not deteriorated much and is still riding comfortably.
The electricity cost for 10 km run is around 10 yen.

The ideal condition for lithium-ion battery is to use between 85% and 40%.
It is best to avoid keeping this battery fully charged.
If charging can be completed in less than 1 hour of boarding, there is almost no state of full charge.
So it's good to use a timer to fully charge the battery just before departure.
Assuming that my bike can run for up to 60km, it can be stored if it has run 9 to 36km from full charge.
If I drive more than that, it is expected that the battery level will be less than 40%, so it is better to charge it.
If you keep data on the time required for charging as shown below, you can use the timer to charge properly.

I have been riding this bike since May 2017.
This is my fourth bike.
It is an electric motorcycle.
Charging can be done from a household 100V outlet.
The electricity cost for traveling 1km is about 1 yen.
This bike doesn't have to go to the gas station regularly,
It's easy and economical.
Only the sound of the wind is heard when riding.
