Questions about electric bikes?

Robert Ful

1.) How long do they last before "burning out"
2.) How many miles can you typically travel on one without having to pedal?
3.) When going up a steep hill, is the bike powerful enough to move upward without having to pedal at all?

Answer
We will just use my Giant Lafree Lite as a sample"

1)How long do they last before "burning out"?
I am 230 lbs,and have ridden this bike 4K miles over 3 years and NO problems other than flat tires.

2.) How many miles can you typically travel on one without having to pedal? I have to pedal on this bike. I can go 30miles on this ebike designed in 2002 and costing $1300.

3.) When going up a steep hill, is the bike powerful enough to move upward without having to pedal at all?
Again, this ebike requires me to pedal, as you should on most ebikes. I have arthritis and asthma, but I can make it up a 7% hill at 7mph carrying 20lbs of groceries

Solar Panel wattage for my Electric Bike?

Solar Panel wattage for my Electric Bike?
I am looking to purchase an Electric Bike for transport to work. I work on an Organic farm and need to save some energy up those hills.

I need help figuring out what size solar panels would be needed to charge the battery, and whether its plausible.

I'm looking at Ebay in Australia as I am immigrating down there. I prefer to afford the foldable/portable solar panel system: 80 watt, 120 watt, 160 watt, but IF necessary a bit more.

300w 3 PHASE 36v ELECTRIC REAR WHEEL
THREE 12v 17ah SLA BATTERIES (Total 36v)

or

Motor: 250 Watt brush-less DC hub
Batteries: 24V/10Ah pack, valve regulated

can anyone out there help explain to me how to figure this out?

thanks :)

Answer
wow
i;d just say abandon all hope
get a regular bike and learn to ride it
get enough of your own juice to ride 'up hills'

you work in an organic farm and you want to get one of these silly heavy slow environment destroying resource wasting electric bikes?
dude

organic farm ===> real bike
seriously

otherwise you are in for some serious electrical engineering or spending about 3 times what a good, regular bike would cost
