Questions on how to care for an Ebike

I have a Ejoe Epik SE on order and I have a couple questions before I ride it. My questions are general electric bike questions.
The Ejoe epik SE has a LED display with a battery indicator that has 4 levels. (empty)(low)(Medium)(Full) Is running an Ebike battery to empty bad for it? If I have it fully charged and take it out for a 1 mile ride, and the fully charged light is still on, should I hold off on charging the battery? Should I always wait till it is medium or low before I charge it?
I have steep hills on my commute. Can it damage the motor if I try to go up a hill that is too steep? What is the tactic to go up steep hills without hurting the motor?

Thank you

You bought the bike to enjoy cycling so don't fret about using the entire range

If you can avoid fully discharging to the lvc cutoff, and don't constantly fully charge u less you need to

On hill u should use the least amount of assist you can handle and pedal in the lowest gear. Higher cadence is better for going up hills

Three to four years is about all u Dan expect from the battery

If I want to ride with no pedal assist or throttle help, can i ride without turning the system on, or should I turn it on and set pedal assist to 0? Why do I hear going down a hill with it off is bad?

I believe the EJoe Epic SE uses a geared hub motor. Thess motors freewheel when unpowered, so you can pedal as long as you want, with very little motor resistance. You can also coast downhill w/o pedalling. Also, most of the simpler PAS systems,yours has 3 levels, will cut motor power at a certain speed. So in PAS 1, if you pedal harder than what is needed to maintain the max PAS 1 speed, you're doing most of the work.

With my DIY ebike, with three level PAS and geared hub motor, I often ride it unpowered for more exercise, especially when riding with my wife. She's on her ebike going 12 mph. I can do that w/o power.

In my opinion, one should ride a geared hub motor e-bike like it was a regular bike. Pedal, use the bike's gears, and help the motor out. The motor will run cooler, and its gears will last longer.

I don't charge my battery after a short ride, but will accumulate the ride time in my head. Maybe three or four short rides warrants a charge. I also charge the battery using a timer set at 6 hours max. I don't want to go forget about it. Finally, I will charge no matter what, if I plan to take a long ride the next day.

Answers (my opinion only)

1. Yes, running battery all the way out is damaging but the management system probably will prevent you from doing that. Good idea not to run it out anyway though.

2. Yes, probably no reason to top it off after a short ride like one of one mile.

3. For ideal, practical, long life of the battery you probably would run it down to about 20%, then recharge. But you have to balance this with common sense, depending on how far you're going to ride next time. As mentioned before, the battery management system will keep you from the worst abuses, probably.

4 & 5. Once again, this system will probably shut down before you damage it, but it's better to be proactive and pedal along on a steep hill to help the motor out.

And here's an answer to a question you didn't ask. Get yourself a good set of flat resistant tires like some made by Schwalbe. Flats are no fun with a hub motor.
