Let the hive mind of Engadget get that for you.
"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
This is what people should use for an ebike.
Ebike Recipe:
1 Inexpensive steel frame bike frame. Ebay has $40 versions.
1 front hub motor 48V and 500W or better. with charger and throttle: $400
Used fixed gear powertrain to keep costs low.
1 Xtracycle, to provide battery cargo and extra cargo. $400
4 sealed lead acid batteries. 10Ah sized should do. $300
Optional: 40W stereo system and mp3 player for rockin' out
Rear wheel should be really fat, stout, and wide to soak up the battery and body weight. This bike will weight at least 120lbs. alone.

Put that all together, wiring and such. And you've got a bike that you need to pedal up to 12 mph before you hit the juice to extend your battery range. I'm 'guessing' this kind of 10Ah battery can run 30 minutes or more at med-high speed with your low speed pedal assist.
Lead acid batteries are heavy but they're cheaply replaced. If you've got more cash you could go with better power sources. So much work has been done with golf cart systems that you should be able to keep the power around the same size and be able to use the controllers, chargers, or some parts that are commonly produced and easily replaced.
Total: 200bike, 600 motor-system, 400 xtracycle, 300 batteries = $1,500
Wow. That's an awful bike for a ridiculous price! Most pre-builts are much better than homemade e-bikes these days.
I have a 36 volt, 450 watt 12ah bike. It has a hub motor, and a sturdy frame that can handle 240 pounds easily. It gets about 30 miles per charge, and a charge costs pennies. It manages a speed of 18 mph, and even faster when pedaling. (I could make it faster, but I don't like going faster than 25 on a bicycle, and besides, that's illegal and not safe for sidewalks.)
The battery pack doesn't take up the rear rack like a homemade bike, so I can actually use the bike to go grocery shopping and bring along some cargo.
Total cost of my bike? $800 and that includes $100 to ship it across the country via UPS.
So mine's sturdier, faster, has better range, and has more cargo space, and it cost less than that frankenbike you just described.
WHY would you build one that costs more and does less, and doesn't come with a 1-year warranty?
And where did you get this bike from?
xtracycle looks ughlee.
e+ is worth it
