Well the end part in Blue does move when twisting throttle, even the plug in middle too, But Im wondering if I grip the part in Red, and also hold the rest of grip in other hand would it unscrew once i can remove that plug thing in end

There's an expanding wedge-bolt arrangement on the inside, which grips the handlebar on the inside when you tighten the screw. If it's not too tight, you should be able to grip the red part with pipe-grips or mole-grips, you can probably wiggle the whole lot out.

Yes, a bit of cloth to prevent that end part getting scratched gripped with one of these:

I dont think like i have said it will turn or unscrew, as its part of the throttle, but like you have all said I maybe able to wiggle it out. But will it damage the throttle as dont want that to happen, but I will try a lever on the gap 1st and do it slowly, as it must come out to have end bar mirrors as It would be the best to have as then i wont see my arm in mirror.

you all have been very helpful. Ive not had a good 2023, as I lost my brother on 1st december, and it broke my heart. he had pulmonary fibrosis. so all this has helped my grieving.

Sorry to hear you lost a sibling.

Good that messing with ebikes is helping.

 

[thelarkbox]

Fwiw my experience is limited to a couple of ebikes with throttles fitted BOTH were secured at the inside end. So i would get that end plug out using all the persuasion necessary without ant worries about damaging the throttle..

If you look at the inboard end of your throttle, where the cable housing is, somewhere there will be a grub screw tightening the collar onto the handlebar. If you loosen this screw you will be able to slide the throttle off the handlebar - hopefully there will be enough spare cable to allow you to do this.
Then you'll be able to look inside the throttle twist grip. I think you'll find that the 'end cap' is merely part of the twist grip moulding and can safely be cut/drilled out, allowing access for a bar end mirror.

This is the type of throttle on my wife's Big Bear (though hers is a right hand one).. It had a moulded end, which was cut off with a junior hacksaw, to fit a bar end mirror. Throttle still operates fully:

Well I have managed to get throttle off the handle bar. I have tried removing end part, with a flat end screw driver, keep levering all around it but still wont come off, it just seems to me something holdint in tight like a screw. But I looked inside and no screw. I cant show a inside pic as i cant get flash working on my Iphone 11




Its nearly off but I keep thinking is it going to damage throttle grip as its so tight as all of it moves even end cap when you twist throttle

Thanks that put on the flash, Well it seems I was right. there is a nut of some sorts in centre holding end piece, as i see now that black centre bit is now looser but need to now find something to hold that nut. long nose pliers thats if i can frigging find them lol always same never find what you want got tons tools lol




Not having any luck here at all its obvious to do with that centre screw above but can I find a pair of long nosed pliers Ive got some but just cant find them, will keep trying maybe a socket set bit

I give up lol as i have tried several sockets on that inside nut or what ever it is but cant seem to find one which will grip it tight

I'd hold that end cap part in a vice and saw, turn it around a bit, saw, turn, repeat, sawing through the endcap all the way around, then saw through the bolt.

I don't have a throttle on my bike. If the throttle doesn't work afterwards, replace it with a thumb throttle, if you must have a throttle? Otherwise just replace it with a grip.

Well in temper lol as no way could I get the frigging end piece off as it was being held inside by some sort of nut. but have now forced end cap off, but now i see the end bit seems to be solid. weird or what, But do you think that end rubber piece can be cut off and also will I now be able to have a end mirror, as it has to be hollow now



could the above be cut off


f

I tried the throttle and it still works ok. but i have this connection at end with 3 pins

 

[guerney]

I'd drill a hole through the middle of this, put it back on the bike, order a Zefal (I prefer the Dooback II because there's no adjustment needed before a ride, it either snaps to a pre-defined angle which either works for you or doesn't. If it doesn't, you should have bought a Zefal Cyclop. Also because the Dooback II has a larger mirror), then make the hole larger as required for whichever Zefal/other end-bar mirror you've bought, when it arrives. You should be able to make radial cuts through that plastic using a Stanley knife, once it's on the bike, then cut those off, cutting around the innner circumference of the handlebar end.

The Zefal Cyclops has a much better folding mechanism than that one. You can see a bit more with that one, but it's not nearly as convenient as the Cyclops.

Ok will check them both out when you say the Cyclops is more convenient in what way can you explain

 

[saneagle]

The Cyclops folds flat on your handlebars, so it doesn't get tangled with other bikes in a bike rack, it doesn't get caught on those stupid barriers they have on cycle paths, nor in narrow gateways, nobody sees it to nick it when you park, and you can fold it out the way to lean your bike against a wall. The folding and unfolding is instant.

It has the same expanding clamp mechanism that all bar-end mirrors have. You push the spiggot into the end of your handlebars and tighten the screw.

The hole in your handlebars should be around 20mm. It's a standard size for all bnormal bicycle handlebars. If the spiggot on the mirror is a lot smaller, you can wrap something around it to make it bigger. I think the smaller ones normally come with an adapter. The Cyclops will fit your handlebars.
