This is the even newer stuff I've built.



$400 for the 1680W electric motor kit and programmable Kelly controller.
$850 for the battery and charger.

Don't even ask about the customers full suspension mountain bike, it was at least 10x your budget itself and worth every penny.
That's a really cool set up KC.
How is the performance for that set up because I bet it's a blast to ride.
I recently moved my battery from a rack to up front and that made a huge difference in handling. I just wish I could fit one of those battery on my bike.

Well yours is pretty cool too!



You went with the rear electric hub correct?
Looks ideal for that bike.

Where to put the batteries is always an issue, on a 2-wheeler anyway.

I built 3 electric shifting trikes and had huge LI battery packs made that would fit in the case I found to mount between the trike frame and basket with everything in it, even the charger, a keylock, and 3 12V back lights to run of their 36V system.



Point is, I like motor gears, regardless of power source.

The Sick Bikes electric kits have the main good parts you need for $400 if you want to tie into your bikes gears with a good electric base and drive system.
NOTE, the only different part between the 36V and 48V kit is the throttle as they are voltage specific.

The motor and controller will take most anything you care to throw at them, and where you care to mount it is up to you.

On the mountain bike I had no choice but to mount under the down bar.
On the trike I could put it where it fit best and out of the way.
On this 24" 3-speed build for a petite gal, a little $375 36V LI battery system worked just dandy with the motor in the cavity.



Fitting in the cavity can work though, even if you use a big ass battery meant for trike in a 2-wheeler like this one.



And of course if you don't really need to travel far you can get away with a smaller battery and mount everything in a tight package that, well, you get the point.



I like electrics, I like using gears with any motor, this is how I get both.

Yeah as much as I'd love to build one of those, which I will in the future, trust me on that but for now, one that'll drive at least 12 to 15 miles 5 days of the week with out requiring more then a single charge a day, doesn't have to go fast, just can do a good deal of the leg work, that's what I need, though a gas motor kit seems more and more my only choice, I can get a 33cc 2-stroke for 200 or less and all I'd need to buy after a kit would be a gas tank for 20 bucks, eletric kit, its about 260 - 280 plus 75 for batteries I don't even know will go 12 to 15 miles a day on a single charge.

You can get a full nice complete 66cc 2-stroke kit delivered from http://gasbike.net for under $200.
Electrics are expensive, period.
I showed you examples with price ranges, what you do with that info is up to you.

Yeah, I'd love to get a 49 or 66cc kit but I don't have that kind of luck, that a cop won't pull me over out of the blue and know what he's looking at, though I've never been pulled over I just don't want to take the chance heh.

So it'll have to be a 33cc motor kit.

Heh, I can't seem to decide, I'm thinking about just getting a kit now and batteries later, would any one be so kind as to help me find a good cheap yet good charger for 12v 12ah csid lead batteries, that can indicate when the batteries are charged and or shut off when they are charged?

These are the batteries I'm currently considering when the time comes,

Whatever you do, get a charger that has an auto shut off or trickle after its fully charged or it can kill or shorten a cells life. Then you'll have to get a new battery. Only charger I trust for these batteries is a Battery Tender. That's what I have for my jet ski and the battery has lasted 3 years now.

Heres a decent cheap charger for 36v SLAs. I have one and have never had an issue. Cuts off when it should. http://www.ebay.com/itm/36V-Battery...43635?pt=Battery_Chargers&hash=item1e887452d3

As to a 48v 1000w hub vs a 49cc The gas engine comes out in range and speed. The hub will achieve 25mph but its best range will be in the 15mph range, 20 with assistance. Where the gas engine is blown away is by the simplicity and ease of installation, quietness, ease of operation and reliability of the hub. I like both electric and IC and ride both. For some MBs are an interest something cool and neat to ride and tinker with. If it is to be used as serious transportation user friendliness and reliability are paramount. This is where electric shines.

hm, is 15 to 20 mph with a normal weight rider or will those number with someone that's 280lb plus drop a lot?

Weight affects the amp draw fro sure. If you saw the pic of my cargo bike loaded it is probably close to or exceeding your weight. In reality once the bike is up to speed and efficient the the draw is only slightly more(on the flat) than normal. Start off and hill climbing will eat watts. For max range, pedaling from a stop until you reach maybe 8mph the bringing in the motor, and pedaling on any hills will greatly help. I can set the cruise on my Magic Pie at 15mph and only pull 3-5 amps. Riding an ebike is all about good management. Kinda like money, you can be miserly with the watts or blow em on good fun.
