People ask how can i increase my range? how can i increase my power? without sacrificing weight.
You cannot, it took this weight to trust ratio to get Neil to the moon.

You may buy an alum e-bike to save weight but it has 1/3 the tensile strength of steel, meaning it cracks a third quicker and is hard to repair. buy a bigger battery now you have more range OR more power. not both and added weight so you need more power. catch 22
Until a small high amp power pack is invented we are stuck. Lion is the best right now in cool Canada but heat kills the cells, so sorry Mexican summers.
There are ways but complicated to increase range, take wind direction and speed into account, study a map with elevation, long slow downhill, short steep uphill you can walk the bike, etc. it all makes a huge difference.

There are hills and hills. Steep climb with low torque motor will overheat both motor and battery, drain battery fast, could blow the fuse or stall the motor and potentially kill it. The moral of the story - know your limits.

Li-ion work fine in hot climates. But they don't last long there. In Mexican summer you don't want to be on a bike, you want to be on the water or nodding off under palapa until early evening. Why do you think local stores are closed from 1pm to 4pm? :).

Not even going to comment on this one
Such sensitivity to a member’s grammar... my , what sort of people are in today’s world !
Here , i had made the correction , hope that you’ll feel better.
“their ebike up a hill” - “uphill” , allthough “up a hill “ is also correct.
“ to ride up hills” - “‘to ride uphills”

Not really an option, as there are essentially no bikes made out of steel. Aluminum took over as the mass production material of choice well over twenty years ago. Also, aluminum frames are designed differently that steel frames, so cracking is less of an issue.

Regarding range, that's easy.
1. Slow down
2. Pedal harder, keeping PAS levels to a minimum.
