Fits on the golfboard.
The media could not be loaded. Looks just like the original that came on it. The cord was a little long but I made it fit. Works great good quality. The one on their website was $100 so way cheaper for the same thing.

Responsive and tight!
Throttle mounted and wired up with no issues, heavier gauge copper wire, bright LEDs, can handle up to 72V with a little heat.

Works but was wired wrong
It is a 6 wire throttle with 2 wires jumped to one making it a 5 wire. But mine was wired wrong. They had the brown and green jumped together that left the battery indicator on even with switch off. So as you can see in the picture I connected the green and yellow together and indicator goes off with switch. Hooking it directly color to color to controller wires it did not work. The indicator shows red in pic because it is hooked to a 36v battery for demo and it is a 48v. If the indicator is not accurate most likely it is not calibrated for lithium battery. I am adding a mini volt meter with ammeter to the bike. Search for it here at Amazon. They are cheap and programmable to your battery if you choose the indicator meter as opposed to numeric.

Did not work
I’ve been building ebikes for 15+ years and have installed several hall devices (throttles) in all voltages ranging from 24v to 72v. I have never had a single install fail till now. I have to question if the unit I received was new or returned because it had connectors already installed on the wires. But the photos on the site show the wires without any type of connectors. Of course the manufacture could have change their offering after the photos were taken. The real problem was the fact that who ever installed these connectors (manufacture of 3rd party) they did so incorrectly. This throttle controller has 6 wires and most ebike controllers will have some variation of 3 to 6 wires for the throttle depending on how it is expected to function. In any case you should never connect multiple wire together. But that was how this can from Amazon. So I am speculating that someone improperly wired it and damaged it. It was returned and subsequently sent to me already damaged. I returned it for a refund.

Forget the battery level, throttle modulation is good
I have it paired with an LCD 820 controller (older EBikeling). Do not even bother to look at the battery level, it's probably wrong. The throttle modulation is good with this, but I wonder if it's from the controller or the actual throttle. Will test that later.

It worked
I had purchased the unit with a twist throttle and decided to put it on a another bike but needed the thumb. Emailed seller and they sent me this link. It worked perfect. Did have to change some connector ends but works like a charm.
