new throttle help please

[deecanio]

Hi All,

I wondered if you guys know anywhere i can get a nice full grip throttle for my upcoming build?
i have a crystalyte 36-72v 35a controller and i'm after something that will plug straight in, give me a good quality rubber grip and come with a matching grip for the other side?
Do they make them?

cheers all,
Nice to see everyone again

I think you can use all the throttles they list but you may have to make a new plug. worth checking first. doesn't mark have any?

I know you can get a Magura full grip throttle. It's a potentiometer type throttle, so in order to use it with that controller, you'd want to add a pair of fixed resistors in line with two of the wires (not the signal wire), to match the output of a hall throttle.
EV Deals and Thunderstruck used to have them.

I'm not sure where you can get a full grip hall throttle.

Hi Nick,Fechter,

Thanks for the replies - Nick yes Mark did supply me with a throttle but it's made from hard plastic and doesn't feel very nice at all, i dare say a few blisters holding on to it will ensue
I will pobably have to use it though as i don't know squat about the electrics and even soldering a couple of resistors is quite daunting for me (stop laughing fechter ).
You guys will see as i blog my build that i am a complete novice and i'm relying on knoxie and yourselves to help me through.
I have all the parts i need but i need to get some torque arms made and whilst i'm at the machinists i going to see if they can make me a new seat too.I have my blog on the other "v" site which i i will update this weeked although it's such a slow site that i'm thinking of movin it here - the idea was to blog a novices build so if anyone else like me wants to try and build an off road ebike they can look at what's involved - do we have blogs here or should i just start a new topic and post my progress there?

Once again thanks for the help guys

These guys show one on their website:

Look down on the page for the X-T300. That should be simply a matter of matching the wires up properly, no resistors needed.

 

[deecanio]

i think that's the one i've got !! lol
i think some more home brew is needed here - the action of it is certainly nice enough but the grip itself isn't the greatest, i'm tempted to take it apart and look how it works is where all the tinkering begins? damn it hooked now.

All the crystalyte throttles work on the same principle.. only difference is the

LED

or

Non-LED types..

The LED throttles can only be used at 36 or 48v.. and have a potential of shorting out in the wet.. the +5v for the throttle and the circuit board lead are very close to each other and when wet " Can " go Full-On by accident !!!.. Be Aware !

Non-LED throttles can be used at any voltage..

The thumb. half twist.. or full-twist all work on the same principle, the grip itself is differnt in apearance only.

Personally .. i like the look.. feel and everything else with the half-twist the best of them all.

Yeah, my kit had a full twist when I got it, didn't like.

Well, most people if they have a bike with a grip that's gotten loosey
goosey, they would try to repair this. A full grip throttle is broken like this
by design... Just try & hop your bike over a pothole with a grip that's
designed to turn out from under your hand... As far as handling/safety
goes, I'd rate it worse compared to no grips on the handlebar.

Obviously, your mileage may vary...


But it's with that in mind that I've gotten a half grip to replace it. I figure
that having 1/2 of the grip that's actually usable as a grip should make for
less of a handicap? Havn't had the chance to try it out for real yet...
If I had to buy another throttle, I'd try half grip or maybe thumb.


BTW, Garry of http://www.ebikeconversions.com/
got me my throttle + both grips for cheaper then powerscoots or
electricrider sells equivalents. Quite a bit cheaper at it.

The one I got is "Standard Half-Twist Throttle" as seen here:

Being a long time motorcycle rider, I preferred the full grip at first, and the Magura is a well made one that feels just like a gasser.
But the Vego came with a half grip throttle, a pretty nice one, and I got used to that pretty quickly. Since I have several of them in a box, that's what's going on any future projects. I dread thumb throttles.

 

[deecanio]

yeh i agree the thumb throttle is not for me either -i rode a quad with thumb and i didn't like it all.
ypedal i think advised me to go half throttle so i could grip well over the rough ground,this is probably the best option but i had motorcycles too so the full grip keeps calling.
the magira looks better than the one i have would i need to change connections?

 

[bobmcree]

i also prefer a full throttle having ridden motorcycles for many years. none of the ones i have ever seen have a soft grip. you could get a foam slip-on and make them softer.

if you use a magura pot throttle on a system designed for a hall throttle you will have all the throttle in the middle third of the rotation. this is because the pot goes from 0-5v and the hall throttle only goes from 1-4v so the controller intended to use a hall throttle only responds to 1-4v.

you can make a pot throttle work properly by adding resistance to both ends to make it span a more narrow voltage range. on a 5k throttle if you put a 1k at each end that is a good starting point. a 2k pot at each end would let you completely adjust the span and range.
