Throttle handles

Hello all, I am enjoying my new Via Lento but have one concern. The throttle handle, that is, the part that actually twists, is very short and causes some irritation to my web of my hand between my thumb and index finger. Does anyone know of replacement handles for the throttle of a Currie Via Lento? I'd like one that has the whole, or majority, of the handle that twists to make the throttle work. Would appreciate any info from you experienced bike 'modders'.

eBay has plenty of "Full Twist" handles...
Any regular one will do..
Does your current throttle have LEDs on'em? If so, you would want/need a replacement full twist throttle with LEDs as well...

eBay is a wonder...

Thanks, Sangesf,
I'll check on eBay. I didn't know if there were some kind of "special" throttles, or what, that had to be used. Yes, it does have LED lights and thanks also for that bit of knowledge. I also have to take the bike to the shop as they will be putting on fenders. I have to wear dress clothes to work and sometimes drive through puddles or water in the gutters of the street. Dave said that he'll check on the throttles, too, but I got the impression that he would check with Currie.

So, if I get one of the full twist throttles, is there any special 'trick' to removing this one and installing the new one? I imagine that there are wires to disconnect and re-connect. Thanks again for your helpful knowledge.

To change throttle.

First off, you can get a replacement one for about $25 +shipping from electricscooterparts...
If your LBS buys one from Currie, I'm sure it will cost $50+ and don't know if it will be full twist or not..

To replace the throttle is quite simple...
On the throttle is a little "set screw" that holds it in place.. A couple of turns with the correct bit type will loosen it up to be able to be taken off..
(P.S. Make sure the BATTERY is DISCONNECTED (not just key "turned off") BEFORE you do any of this! - disconnect battery and turn throttle to make sure bike doesn't move!)**

Once off, somewhere along the throttle line, you can just cut the wire {forget about the connectors, they NEVER match** (also, remember, battery MUST be disconnected before you do this!!! - and preferably after a few minutes have passed). There will be FOUR wires inside..
1.) Red. Red is the main +5v power line to the throttle.
2.) Black. Black is the main ground wire.
3.) And 4.). There will be two other wires of any different color schemes..
One of those is a variable (~ 0-4.xV) line for throttle to controller control.
The other is a main 24/36/48v power line from controller to throttle to light the LEDs on the throttle.
(whatever voltage your bike is - oh and remember to buy the correct voltage led throttle)

Here is the part that is "tricky"..
First you will need a volt meter...
In order to figure out which wire is which... (at this point, it would be a good idea to connect red to red and black to black and have the other two wires taped up so they don't contact each other and especially the black wire)
With the red (taped up) and black connected (untaped, but attached - make sure it's not touching any other wire(s)), you re-connect the battery...
(P.S. If the black is not connected when you re-apply power the bike will take off at full throttle!)

With power supplied the two remaining wires will be variable (0-4xV) and main power.. Take your voltmeter and place black probe on black wire and red probe on one of the lines..
One line will read 24/36/48v and the other will read about .5v and at this point if you turn throttle, you will see the voltage vary between that at 4.xV. (P.S. Remember, Do NOT connect either of the remaining (2) wires between controller and throttle YET!)

Just make sure on the NEW throttle they tell you which is the variable line and which is the main power/led line.

IF you hook up the main power line (from controller) to the variable line (on throttle) you WILL blow the throttle and most likely destroy your controller, so make sure the correct ones are connected.

Once you have all wire connections figured out, DISCONECT the battery again, BEFORE you (re-connect) the respective variable and power lines.

If you have any other questions, feel free to ask.

That's "simple"? Uh, ok Sangesf, if you say so! Right now, I'm using my gloves that I used while riding my gas powered moped. Seem to work good, pain is mostly gone from my hand. I figure I'll wait until after the rainy season to do the throttle though. Thank you for this "simple" instructions on changing the throttle and also the tip about the connectors 'never' matching. Seeing them on the electricscooterparts site, I thought "oh hey, just disconnect and reconnect". Guess that's not easy enough! Thanks again and I'll save this email for after the rains, Sangesf.

It s simple...
There's only 4 wires...
2 are ALWAYS red/black..
The other two are the "confusing ones"..
The OTHER way to tell which is which (if you don't have a voltmeter) is to remove the sheathing (covering the mass of wires) from the 4 wires.. Red is +5v. Black is -5v.
Cut ONE of the two remaining wires...
If the LED lights go out when you cut the wire, you know that's the main power line to power the LEDs.
If the LED lights DON'T go out, then that wire is the variable line..
Simple!
