Please, name people or shops who've been helpfull and cool in getting the stuff you wanted or needed.



The only one truly awsome guy I know of in the feild is still Justin Lemire of ebikes.ca I purchased one of his drain brains and was blown away by the service, not only that but the product it's self is top notch and works as advertised. How could I not highly recommend him?

Well, the only one thing is his shop dosen't appear to carry the split throttle w/grips & like a bag of anderson powerpoles that I presently want. :?
 
I second the nomination of Justin, for all the points you mentioned,
I have witnessed myself.

You might get a half-length (less, really) hall effect throttle from the *yucko* Currietech people. It's proven to be a good and reliable unit.

I'm also liking the batteryspace.com 14.4V water bottle NIMH battery that came the other day. They are a good company too.

But Justin? He's the best!
 
Welp, Garry of Ebikeconversions was pretty cool:

Todd at Electric Motorsport has all sorts of parts for electric bikes, scooters and motorcycles. Not everything is listed on his website. If he doesn't have it, he can usually tell you where you can find it. Check it out here:

Another good guy is Brian Hall at Thunderstruck Motors. About the only place you can get a Transmagnetic motor. He has all kinds of motors, batteries and controllers. He's also a dealer for Prima electric bikes.

I've been ordering my parts from Scooter Support

http://www.scootersupport.com/scooterparts.htm

They're located here in the Houston Tx area so I save slightly on shipping. I might save more if he actually ran a retail store where I could just go in there & buy instead of just online mail-order, but apparently he only has a warehouse & email.

He's also been helpful about answering questions & recommending compatible parts.
 
Mathurin, I know some place here in quebec where you can buy anderson connector.. powerpole or not... large shrink tubing for battery and alot of stuff for ev... it's on the Watt road near the industrial park. the shop is seeling stuff for ev and solar equipment.

But for throttle... maybe one place i guess for that here in Quebec.. near Hamel and Masson blvd. the huy sale electric bike.. it's a ebike shop.

Contact me for info.

Yeah Goudreau bicycles, actually the garbage-picked frame I'm using now has a sticker from that place, though it wasn't electric. I've been there, the guy said he had parts as spares but wasn't interested in selling stuff. (!?) Otherwise I would have gotten a MY1018 + controller + throttle. Oh well.

As for Anderson PP, I know electro-mike don't have any, Madison probably have cheap Chinese knock-offs but do not want. Active electronics maybe?
 
I don't have a store but i do have a bunch of Anderson Power Poles 30A and 45A in RED, Black, Yellow, Green and Blue. $0.90 each.

i also have a good stock of all of the flat black connectors like those used for the Crystalyte, Cyclone and WE throttles i have them in 2,3,4,5 male or female for $1.45 each and the 6 (Cycle Analyst) and 7 (Cyclone throttle) for $2.00 each. or you can buy just the contacts, 10 for $1.00

i am in Ontario so shipping in Canada will be Canada Post for Letter sizes and Fedex for larger stuff.

Don't know why this hasn't been mentioned, but someone has an eBay store for PowerPoles. I got like 10 30A pairs worth of them for like $16 total. I managed to get an even better deal out of someone else: 25 pairs worth for $22 total.
 
What do you guys suggest for battery connections Andersons or XLRs. And what do you think of these as a possibility?

Unless you've got a monster of a charger, Andersons are overkill. XLR 3 pin connectors are used on most smallish scooters/ebikes/skateboards :p.
 
electricscooterparts.com carries lots of misc stuff for scooters, and I've had good experience dealing with them.

I've placed a few orders from powerwerx.com for anderson connectors. They seem to have pretty good prices.

For other stuff, check an electronics supplier, hardware store, auto parts store, or Radio Shack. I noticed True Value carries replacement motor brushes for power tools which might work for small EV motors.

For power transmission parts, and other misc stuff, I've had good experience with surpluscenter.com, but they charge a lot on the shipping.

For misc power transmission parts like bearings, these can be found from an industrial supplier, but it's good to call in the part number for a price quote, because sometimes industrial parts can run kind of high.
 
I have had a bad time trying to find connectors for those on controllers. I was going to strip all the connectors off and splice the wires together. Then I found this website.

http://www.electricscooterparts.com/wireconnectors.html
 
If you are a DIY type an excellent source for parts is http://www.hobbycity.com.

They cater to RC hobbyists so don't expect much advice or support for ebike applications. But as RC has matured they now carry lots of products of suitable capacity and durability for ebike use. I haven't yet tried their motors, controllers or batteries. A few ebikers have with varying degrees of success, but high rpm RC motors are not easy to adapt to a bike. Their LIPO batteries are starting to look increasingly attractive as the larger format 5AH cells are getting better and cheaper.

I regularly buy from them connectors, wire, shrink wrap, wire mesh guard, etc. And I really like some of their watt meters/power analyzers, battery monitors, battery chargers, power supplies, etc. Especially love the iCharger208B and the Junsi celllog-8. They are in Hong Kong and I'm in the US, but I've found them about as easy to order from as local suppliers. If the products you are ordering are fairly light the shipping charges are reasonable.

As for connectors, I used to be a big fan of Andersen powerpole connectors and bought the 45 amp version in large quantity. I still like them but don't use them nearly as much as I used to. I never bought the high end crimping tool for them and perhaps if I did I might like them a little better although I'm not certain. With the cheaper crimper I have it is a little bit tricky to make a secure crimp without deforming the connector. I only got really consistent results with 12 gauge wire. With heavier or much lighter wire I had more issues. Sometimes after crimping I have to tweak the angle of the blade connector a little to get a snug fit in the housing and make good contact. I eventually settled on a process that involved lightly tinning the wires, lightly crimping and then soldering which gave me good results. But even so I find that over time the quality of the connectors degrade and the contacts loosen and the resistance increases. In my use I find them typically good for about 1,000 connect/disconnects before needing replacement.

I mostly switched to using the RC connectors, the polymax 5.5 mm aused with 10 gauge silicone wire are now my favorite for power connections between the motor controller and the batteries and motor. They are not quite as convenient to connect/disconnect and you need a method to prevent accidental shorts, but they provide a better quality connection. They are solder only, no crimping. I find them much easier to install/service/replace. Btw, I protect my connectors from shorting with little boots over the male connectors and shrink wrap just slightly extending over the tip of female connectors. I make the boots from short lengths of narrow bicycle inner tube cable tied on behind the connector such that the boot extends past the connector tip by ~1/2" of an inch.

My second favorite supplier is Digikey. They are pricey, unlike hobbycity. They have a great selection of electronics parts and ship small orders fast and cheap.

My favorite supplier for motors was Kenny of Crystalyte, but I haven't ordered from him recently and don't know if he still deals directly for orders of a couple dozen motors at a time or not. He was never great to deal with as orders were often slow to be processed and shipped and were rarely filled 100% correctly. But the prices were good.
 
A lot of the white/opaque conectors for the throttle and e-brakes use the 2.8mm (0.110") spade Sumitomo mini automotive connectors, as used on motorcycles. Alternatives include Narva 2.8mm mini tab, male p/n 56218, female p/n 56222.

These connectors are sold by many electric scooter shops, as listed above, but are also available from auto eletric stores like:
http://easternbeaver.com/Main/Elec__Products/Connectors/110_Connectors/110_connectors.html
http://www.oregonmotorcycleparts.com/connectors.html
eziautoparts.com.au

or eBay stores:
towzatronics, AutoStar-Shop and Kojaycat-Vehicle-Wiring

Be aware that there are some differences with female pins and housings - not all female pins fit all female housings - so best to buy the housing from the same source as the pin. I have had no such issues with compatability of male pins & housings.
I also noticed that the male contact pins are generally a thicker material so use a slightly wider crimping die, ranging from 3.0 to 4.0mm, while the female pins use 2.5 to 3.0mm for the non-insulated and insulated wire sections.

The smaller black connectors generally used for pedelec, some throttles, CA, etc are the JST SM with a 2.5mm pitch.

Pins
male pins are BYM-001T-P0.6, RS Components p/n 392-2240,
female pins are BHF-001T-0.8BS, RS Components p/n 392-2385
about $4.50 aud for a bag of 50.

Housings
male SMR-02V-B for a 2 pin, RS Components p/n 392-2256; SMR-03V-B for 3 pin, etc.
female SMP-02V-BC for 2 pin, RS Components p/n 392-2391; SMP-03V-BC for 3 pin, etc

Also available from Digikey, refer this post http://endless-sphere.com/forums/viewtopic.php?f=3&t=52292

Also available from E-bikes.ca, along with crimping tool TNI-U double crimper model TU-190-08, which crimps both bare conductor & insulation in the one operation.

I find the Engineers PA21 single crimper works well, I use the 1.9 die for bare conductor and 2.2 for insulation.
Others have had success with the Molex multi crimp tool.

It's fairly easy to remove the female contact from the housing but I often struggle with removing the male pins.

Based on the comments looks like these work with the jst connectors and is loads cheaper then anywhere else.

What are the basic mechanisms behind thumb throttles? I wish to design and produce my own. Is it some kind of spring-loaded potentiometer?

Most of them use a hall effect sensor and moving magnets. You can use a potentiometer as well, but those tend to have limited life as the wiper wears out.

There are several variations on the magnet/hall sensor arrangement. I've seen both single and dual magnet setups.
Below is a two magnet type.
