Time to get parts for ebike! flying to Las Vegas

[Carmageddon]

I am finally going to get my chance - I am flying to Las Vegas for a conference on February 1st, will be there until the 7th.
During that time, I will have the first 2 days totally free and could do anything.

This is my chance, can you help me find a good place to buy the needed parts, for a 60KPH e-bike preferably locally, failing that located nearby up to California to which I can take a quick drive for the parts, and failing that, a place which can ship Continental in the USA to Las Vegas?

My needs are: 15KM driving range - must.
Cruise speed of 60KM/hr maintainable for 15KM - must.
Preferably to be able to burst up to 80km/hr (only if this would not drastically raise the cost of the system!).
Batteries to support this range+25% or so, but not more since I would prefer not to spend more money on a range I will not require.

I will have about 15kg+ free space in the baggage, so I could even bring back strong, good rim+wheels to support the desired speed.
Will I need torque arms as well? if so which? would you need detailed pictures of my bike to determine this?

I am asking for help, because after all the readings I've done, I still dont quite understand, what FETs do I need in the controller, how many winding in the motor... I think I want a balance between speed and torque, so I guess something in the middle would be good.


Please, help pointing me to a recommended stuff and places in the US


I know this is the third time I am asking, but I learned from the feedback on the previous threads, and so refined the list of requirements - this time I really believe this will work out, and I too will be proudly commuting to work and nearby stuff in an e-bike, and minimize the spent money on fuel!

So thanks again to everyone 8)

Now that you mention 50 mph, you just DID up the ante by quite a bit. And it will cost ya.

Methods seems to have a few hubzillas. http://www.methtek.com/2012/06/03/greyborg-cromotor-hubzilla/

But if you drop your expectations to breifly touching 40 mph, and cruising at 35mph/ 55 kph, then the Yes com motor I mentioned in the PM should do it when run on a 72v 40 amps controller.

One US source of the controller would be Lyens. Look for the 12 fet controller in the for sale new section of ES. Or just have one sent from china to your home, from an ebay vendor.

Battery from hobby king, shipped to your home. 72v 10 ah RC lipo, 30c or better. You'll need the charging stuff, A good US supplier of that would be EP Buddy. http://epbuddy.com/index.php?main_page=product_info&cPath=17_20&products_id=169

Also you can get wire, bullet connectors, cellog 8 cell checkers, and such from EP buddy.

If you have some lead time, you can have the stuff shipped to where you will be staying in the US.

when a ebike reaches a speed above 63km/h the handle bar can be wobble badly, but if you go 60km/h for a max speed will be good enough, and battery will be just 17cells of 10amps will do, better is 15amps.
im quite happy to stay a best speed is 55km/h all the way, fast and easy to stop any time. 14 cells is not bad also, at 58.4v it can reach a top speed at 58km/h ? so that is line if you want 1v per 1km/h .

a cheap controller will able to reach 60km/h , (my favoourite choice max speed), a 60v `1800watts hua tong, or you can also try greentime controller 18fet 4110, 48v - 96v controller, ask them to have the LVC to send to 48v. so in This way you can try up more cells or less cells to find which will really suits you best. my green time controller claim by the seller is a 60amps output but real meter test i can only see is a 42amps - 45amps controller. never reach 50amps. This is fine to me, at a 42amps or say 45amps at 17cells or 15cells you sure will see 60km/h. who knows you will be quite happy with 14cells performance ? I say these two of them and tested them each at least 6months. now my huatong 60v 1800watts 18fets is a white elephant. but is good stand by controller. if my green time controller fails, i can always make a fast quick replace a controller without having to search or wait for a new controller for replacement.

I have never reached 80km/h, so I will temporary drop this ideal now. 14cells 15amps can easily reached on flat top speed is 55km/h, my hub motor is also a cheaper type 48v conhismotor, 1000watt. run estimate 8000km
