These guys sell curry parts for a good price .
Just a link to a 600 watt motor.
They have a lot more throttles, motors controllers, chain, and belt drive electric bicycle stuff.

or a nice throttle. at a nice price

Post links to good stuff please.

For a battery I would have to recommend safe's nicad setup .

I think lipo's are too dangerous.
 
Magura throttles are considered the "rolls Royce" of e-bike throttles nuch better quality than the cheapo scooter controlers...


I would like to add

TNC Scooter

They supply cheap brushed motors and controllers that can be used for
e-bikes

Batteries....I'm aware of the the precautions that need to be taken when using Lipos and would recommend
them in a heart beat to anyone willing to read up on the tech, the ruels to follow are very very simple the
consiquences if you don't are flaming pack, currently there is no chemistry that comes close the the energy density of the lipo
..for those that don't i would HIGHLY recommend Lifep04 batteries from

http://www.evcomponents.com/SearchResults.asp?Cat=28

Nicads are 'ok' but way to heavy in comparison to the above two mentioned chemistries and you need over
100 individual cells :-S (money down Safe will tell us all about his pvc tubes now)

For those only need a low 'C' rated batter ie pulling under 40-50amp the duct tape packs
from ebay seller PING are relatively cheap and he unlike many other chinesse sellers
offer very good customer service, sending replacement cells and bms on occasion customers
have problems with their packs.


Also for brushless bolt on NON HUB motor kits

Those kits from cyclone Taiwan look very nice .
I see they include the front freewheel setup similar to the one I purchased from sickbikeparts .
I need to check on the SHIPPING.
Thanks for the link.
I also need to check up on PING duct tape batteries.
 
Not the "similar" exact SBP purchase the cranks and freewheel (not the HD freewhell thats Whit Industry item) from Cyclone :)

The cheapo freewheel is the achilies heel of the kit and should be replaced with the ENO HD freewheel...SBP carry a non - toothed version for those
unable to remove the teeth themselves ;-) I was told by Paul from SBP that this non-tooth version is made exclusively for them, shall get back to the forum on that, i have emailed White Industries asking if the item can be ordered through a local White Industry distributor, If you wish to buy freewheel cranks check with your LBS, the cranks used are EXACTLY the same as trial cranks (you WILL pay more for them they are superior quality) And white industries have a list of agents for their ENO freewheels, check for your nearest Distributor...

I'm prolly not the best one to ask about using alternator motor for e-bike TBH not something i have looked into or would for that matter. Being a 3 phase motor though . would think a suitable controller would be the hardest part, going with a servo tester and the magura throttle you linked to above would prolly be an option as they are PWM but finding one that would run the motor to its limits might be pricey...as i said though, prolly not the best person to ask. ...IMHO with the price of brushed and even brushless motors and their respective controllers Its less hassle paying the extra bucks for an "off the shelf " solution...**** you can get 1000watt hub motor kits for less than $AU300 bucks now off Ebay if you want to go the quick/cheap/easy route :) Actually surprised safe hasn't looked at it...or has he? He's looking at every other kind of solution, perhaps fling him a PM and ask what he thinks mate ...good luck with it anywayz be interested to see what you can dig up...

Why do you guys prefer cyclone-tw.com over cyclone-usa.com? I didn't know advertising was allowed in just any thread, but since it obviously is, I'll plug monsterscooterparts.com. You can get electric motor package deals that include the controller and throttle. The price probably ends up about the same as buying separately. The only problem I have with all these motors is that they always come with a #25 sprocket for that toy like chain and there seems to be no way of buying a bicycle chain type sprocket that will fit the shafts. These scooter parts sellers need to recognize that a great portion of their goods are being sold to bike people, not those toy scooter people.
 
Because Cyclone TW are the manufactuers and offer a MUCH bigger variety of kits Cylcone US dont sell anything over..500watt Cyclone Taiwan have upto and including DUAL 1200WAtt brushless kits

RE: the #25 chain it aint a TOY chain i give you the tip they have a tensile strength of over 700lbs (~320kilo) i have seen more torque put through one than you ever could with 3-4 49cc motors check the 12500KW thread in electric section THAT has #25 chain coming OFF the dual ~6kw motors....runs 0 to 40mph in a touch over 3 seconds (gear limited) i would think puts a **** of a load on the chain wouldn't you? If you don't like them though TNC Scooters sells the appropriate chain for fitting to the motors to use bicycle chain, i wouldn't recommend it though the #25 is ALOT quieter, NO legal electric bicycle will break one it would be an impossibility to break one with a 49cc motor they simply dont have the power... the 1000watt scooter motor has ****load more torque and power than them and they don't break, i know i use one on my 1000watt motor!

As to advertising, i have no associations with ANY of the companies i linked to, simply recommending them from either my experience or those i know that have bought from them, no different from the dozens of times i have seen people recommend sick bike parts in numerous threads.

EDIT: I dunno HOW i forgot this link

http://www.recumpence.com/

(^^^ drive that is on the 12500KW trike in Matts video i linkes to above :) obviously chain NOT on drive in that pic but the #25 sprocket IS)

Two_stage+drive_2.jpg


(Two Stage drive with 6kw motor AND it uses a #25 chain also :) )

Single_stage_drive.jpg


Single stage drive...i have one of these on order for my next project :)

I wont list any prices if interested Email Matt or pm him here on Motoredbikes or Endless Sphere his nickname is Recumpence...

Those more experience than me though recommend them over bicycle chains.

Isn't it true that #25 chain has no rollers? Wouldn't that mean that there would be a lot of friction thus wear out quickly?
 
Mine have no rollers unsure if you can get them with. I doubt it would have a great effect v's a bicycle chain simply due to size difference ie: contact area of chain and roller....but thats just speculation. All i can verify is i have broken bicycle chain (was second hand i admit) on my trike but have yet to break a #25 and they are ALOT quieter...
