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
You will want to have some sort of voltage regulation.
If the panel voltage drops off you don't want to discharge the batteries on your bike.
And you would not want to overcharge your batteries.
Harbor Freight has a fold out 18 to 24 vdc solar recharger.(see link)
For a work/home commute you might not want to haul the charger around everyday.
Ask the folks at the farm if you could set up a solar charging station. They might even help.
I'd suggest a bicycle locker that has the panel on top and a couple spaces for bicycles with charging stations inside, out of the elements. Your employers may like the idea.

How is it balancing on a ezip 500 electric scooter?
Sabrina
I am looking for a scooter that doesn't require a license to just ride for recreation primarily and maybe getting to the shops by my house/library if I feel like it. Can anyone tell me how the balance is on one of these, both standing and sitting? I have not tried one yet or any electric scooter for that matter.
Additional info: 5' foot tall female, average weight.

Answer
Have not seen the 500 in action (Australia has these odd laws about electric bikes/scooters, nothing over 200w is allowed, anything above this is classed as a motor bike requiring a license and registration)
But we do have the smaller brothers of the 500 and they are quite good and pretty stable.
Looking at the images of the 500 it has it battery pack under the floor pan and sizable pneumatic wheels which all should add to it's ride quality.
It is made by Currie, a company with a long history of making electric bikes and scooters

As with anything like this, range is dependent on the weight of the rider and the terrain (i.e. hills or the lack of them) the maximum range given for the 500 is 8 miles but that would be on the flat with the lightest possible rider, the real world number is usually less, say 5-6 as an optimistic guess, less if hills are in the equation. But 4-5 miles is still quite a good distance, I would certainly buy one of these if they were allowed here.
