Having used a twist half throttle (not full length) for a while now, i like the way i can hold it at a particular position by gripping the non moving part of the throttle. It still allows fully controllability of the bike on part throttle.

Anyone who has used one will know what i mean

I've not had any experience with a full width twist throttle, but can imagine that it can be a bit fatiguing holding it at anything in between off and full.

Also, in the heat of the moment i reckon it's too easy to twist it full on and lose stability. I may be totally wrong :o

So that one is off the list for me.

Can anyone tell me how controllable and comfortable a thumb throttle is, especially along bumpy tracks?

Also, do they push downwards for power or towards the front of the bike?

Hope this makes sense

Surely someone has used a thumb throttle

Mobility scooters have them.

 

I think I'd prefer my half size twist throttle.

I've used one, it stuck open, I don't like them much anyway, they don't feel right to me, but there again I'm used to a motorcycle.

Case closed, half throttle it is

I have a thumb throttle with the return spring removed with a O ring against it so it stays where I put it. I tried a twist throttle but it didn't realy fit with my EZ fire shifters. When I cycle I like to have my hands nearer the centre of the bars unless it is a very bumy road. I find not having to hold the throttle open a real plus and you can set it to the power you want.

 

The only thing you do need a brake cut-off leaver with my kind of setup

I prefer the full twistgrip, I tried the half ones but I found they make my hand ache.

I've had full and half length twist throttles and I found the full length much more comfortable.

Which ever one you use get a spare, they are unreliable, mechanically and electrically, I wish someone made good quality ones.

Oh no, case reopened

No case closed, get two full ones!

Actually, having 2 motors and 2 throttles feels quite natural, when opening the 2 together it feels a bit like wringing out wet clothes (yeah weatherman got it wrong again). Well that's how my other arf describes it, you've got to use your imagination a bit.

Strongly disagree, I convert to half throttle always, e-bike full throttles too tiring to hold open all the time. Half throttles allow much finer control on bumpy roads too, the static area enabling the twist part to be held accurately in registration.

 

Motorcycles are different, the throttle action is more linear and progressive, e-bike Hall effect throttles are very fierce acting, not far short of being like on/off switches.

I find the ones I use to be ok in that respect, nice light action, and good control. My other arf, finds her Puma on 48 volts a bit sharp going up our grass bank access to the house, other than that she finds them ok too.

After a couple of weeks with the sunlova kit and a full throttle, my right hand suffers from holding the throttle open (This is as flecc mentioned very different from using a throttle on a motorcycle).

 

I tend to turn the throttle to full 90% of the time and contribute as much pedaling as I can. It strikes me that what I need is a half throttle with the spring disconnected. That way I can use the throttle as a throttle when going slowly around town etc. and leave turned to full when on the open road. The cutoff brake will disable motor in an emergency. It would also mean I could fit bar ends and comfortably move my hands around to relieve pressure.

 

Am I missing something obvious about this set up? Maybe this is what a thumb throttle is:)

Another thumb throttle user here

 

I agree ebike throttles are anything but progressive. All the control is in a tiny bit of rotation.

 

I have mine positioned so with my thumb extended out it holds the throttle full. In the winter I find it get a little numb in the cold but in the summer it is fine.

 

If I had the time or inclination, then some sort of cruise control would be much better. I know devices exist to do this, but I don't think my controller supports the function i.e after a few seconds of throttle, cruise control kicks in unless you brake. You can increase or lower speed with a + and - button just like the cruise control on my VW Golf... great for motorways

You may be able to modify your existing throttle. Here's the instructions for doing that on an eZee bike which I have on my Torq Talk website:

Twistgrip with improved control

Half throttle for me, tried full throttle for a while and it's difficult to control over rough roads and it made my wrist ache. ALso tried thumb throttle and just could not get on with it...

I'm in favour of half throttles only the the ones I have modified myself are about 1/3 width requiring only the index finger and thumb to operate. I experience no fatigue using this.

I do have a thumb throttle on my Bionx powered bike, but the only time I used it was when my chain broke about 3 miles from home:eek:

Hi Flecc

 

Very tidy mod and I should be able to do something similar thanks

Since then I've used a dodge to achieve the swollen inner throttle grip shape John.

 

I just use some PVC insulating tape and wind it round the inner rotating section to form a mound, then slide a flexible piece of grip rubber over it. Tbe left hand twistgrip inner section swelling on this handlebar was formed in this way:

It's really suprising how good 2 small hub motors can climb, and stealth for cheating too!
