- Universal Thumb Throttle for BBSxx
- Designed to be mounted on either side of your handlebar for flexibility
Really good for gunning it, terrible for slowly accelerating.

It truly is universal as I moved it all over the handle bars before I found A good spot. It is great for giving my bike a bit more juice in whatever PAS mode I'm in. I usually only use it for starting faster so i don't piss of cars behind me too much in left turns. For throttle only mode it is terrible at letting you variably apply throttle, but that may just be the factory programming.
Works right or left!

A truly universal throttle. Just as at home on the left or the right side on the bars. Even works on odd custom mounts for recumbents.
Thumb Throttle works great on either side.

Couldn't decide which throttle to go with, finally decided to use the stock thumb throttle and it can go on either side. You can adjust how it work with pedal assist too.
The thumb throttle is ok

I just finished building my e bike this week and have already put almost one hundred miles on it. I am finding out that I would have been even happier with it if I had spent more money on the upgrades upfront. The thumb throttle is one of those upgrades. It works fine just wish I had gotten the half twist grip. Oh the agony of buyers remorse. Do yourself a favor and don't cheap out on some of upgrades.
Simple, just works

Great throttle, never realized how much I disliked other typical small pad (where you thumb goes) throttles until using one of these, works on either side, unlike most that are set up for the right or left only.

Ordered the twist grip originally and traveling rough trails it was a problem. Gripping the grip and accidentally twisting the throttle got me into trouble many times. The thumb throttle saves me that hassle, on smooth trails or street use i can see where the twist would be easier but in my situation this thumb control works.
Totally adequate for daily use

I ride my ebike daily. I only use the universal thumb throttle from a stop and sometimes up a hill for a quick bump. Otherwise it's all about the assist
Works as advertised...

Does the job. Smoothly modulates throttle voltage. Would buy this product again from Luna.

Great safety feature

I'm a senior citizen an a non motor cycle experienced person. I built my electric bike with a handle grip throttle. I found that it was very easy to forget that any thirst to the grip ment that the bike was going to lurch forward. I had several incidents that proved to me that I needed a way to control the throttle that would be harder to accidentally activate. I saw that Luna sold the thumb throttle so I got one.
It has turned out to be much safer for me. I recommend this for anyone who Is not used to the motorcycle style of throttle with the handle grip.
I found itis just as easy to control the motor and safer.
Thumb throttle uncomfortable
Posted by Kelvin Ishigo on Oct 4th 2016
The throttle paddle is a little wide and pokes into my hand when changing positions on my bmx style handlebars. I'm thinking of taking a dremel to it or removing it since I rarely use it. Of course, there are a few times, like starting on a steep uphill, where I might regret removing it...

the throttle works well, and allows for subtle modulation. thumb position is perfect. i have no idea why other throttles are an option, but then I do not use it the bike as a mountain all terrain bike or on single track. Neither do I use it as a fulltime throttle.
Thumb throttle-works good

Many of the bike accessories in this price range are cheaply made. This one is not. You do have to take the grips off the handlebars to get it on because the mount does not split apart but this is one of the reasons for being as stout as it is. There is not a whole lot of range on the throttle but it is fine for me.
If I were to get another throttle I would be tempted to get it again knowing what I know about it.

I bought this throttle to replace the lever style thumb throttle that came with the BBS02. The geometry of the lever style throttle was quite uncomfortable to me. I could never find a position that worked. If they made the lever throttle more like a trigger shifter's downshift lever it would be perfect. Currently it is too far away from the grips, requiring an uncomfortable position for riding. I'm 63 so my hands get numb at times, not with the Universal Throttle.
I ride off road a lot and bumping the throttle while maneuvering can be tricky. I use the throttle to modulate PAS settings, since the throttle overrides PAS and allows soft starts at max PAS without undue amping of the battery or motor in a higher gear. This throttle has the right geometry and has the same responsiveness as the lever style, allowing a good grip and reach.
Only complaint I have is that the body of the throttle is thick and interferes with the selector panel for the display. The selector will not pass over the top of the throttle, and the added width of the Universal Throttle places it further away from your thumb, which makes it less ergonomic. Not a big deal but a bit further to reach.
The thick body also doesn't clear the Bafang brake lever pivot when the brake is applied. This lack of clearance requires compromises in the rotation of the brake levers and position of the throttle. I may file off some of the lever and the selector to make things fit together better.
It would be ideal if the throttle and selector switches were combined, putting all controls within easy reach.
Would give it 5 stars but for the clearance issues. Love the throttle otherwise. Way more comfortable to me.
I'm lusting for the new twist grip to tryout! Hmmm.... a twist grip with a paddle style selector would be pretty sweet too!
