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

electric bike kit measurements?

My 3 girls

I bought an electric bike kit. Not the bike,yet.The motor is fitted on the front wheel. I need to have the hub fit the fork right.What do I measure on my new bike and how do I measure the hub on the the electric wheel. Or am I wrong and need to measure something else?
Thanks

Answer
You'll need to measure the 'over locknut' width of the hub. Could be either 130 or 135 mm. Make sure the bike you buy has the correct rear fork drop out width.
