Which electric bike for a small mountain?

I live on a small mountain with lots of 100 metre-long 30 degree slopes, up and down.

I do not require long range or high speed.

I require 30 degree-slope climbing assistance, the ability to freewheel, and the ability to pedal with zero-drag and cogging, or to easily disconnect the motor from the wheel.

I can contribute 500W of leg power.

What not too heavy electric bike would you recommend: hub, geared hub, roller-drive, mid-drive, front or rear, 250, 500, 750, or 1000W, 36V or 48V?

He doesn't mention having a current bike. He said he wants an electric bike to help get up hill and freewheel down hill. mini gear hub motor does that.
 
A ebike with gears, a strong motor and a good battery.

Unfortunately Israeli customs are eagle-eyed and zealous at stopping any kits and anything above 250W. You wouldn't believe the price just for a 1000W motor alone from a registered importer 'for off-road use only'.

If a 750W geared hub motor is used up a steep slope, is there any real difference whether it is on the front or rear wheel?

try to go mid-drive setup, i started with a 1000w hub an it was nothing but a disappointment it was slow an gutless the smallest hill (think ant hill) an it slowed to a crawl even having to get off an push the bike up hill due to extra drag created by the hub making it hard to peddle

i soon swapped it out for a mid-drive same thing as sick-bike-parts kit 48v 1200w
an haven't been happier, hills no matter how steep are no longer an issue

my advice is ignore hub motors all together an go for a mid-drive as for the "legal"
stuff well in australia i'm restricted to 250w however with NO markings stating
power output anyone that asks has to take my word that it's "only" "250w" (haha)

i limit myself to 30-35kph this keeps me somewhat safe in that i'm not going fast
enough that cops stop me an people don't report me

either way i say go mid-drive!!

You can feel it. But it's not really bad. But I never just pedal. Honestly, too tempting.

How much drag is there from the mid-drive when the power is totally off and one pedals normally?

as Pablo said you can feel it but it's not to bad to be honest, i've done 65km trips with my two 48v 25ah batteries (that's 50ah) without the need of peddling
however i fake it just in case police come along (haha) meaning i peddle but without any load...........

seriously though you can't beat a good mid-drive setup like sickbikeparts kits
an go for a 48volt kit at around 1000w with SBP's heat sink unless you can make your own as i did, to draw heat out of the motor.........
 
You should go with a mid drive. I have a mp3 and if I go up a hill that's too steep and long, my hub over heats and shuts down. After it cools, it's fine. If Sik came out with their kits soon, I'd have on on my bike. Even with regulations, you can always say it's only a 250-350 watt set up. They'll never know.

Yes Pablo, I was referring to your kit. My tablet is pretty lame whenit comes to the auto correct.
Seeing CCC aka Jeff's build with your 48 volt mid drive makes me want one. Mp3s are good on long flat roads but I want something that's going to make it up a long steep hill (4+ miles) without overheating or not make the bike rear heavy for the dirt trails.
