Description
This E-Bike Thumb Throttle is a direct replacement for e-bikes using a compatible 24V-72V controller system, with a standard 3-pin SM-style connector. It’s the style of throttle we fit regularly in our Sydney workshop, built with a durable PC/ABS housing and an 1800mm cable — long enough to reach most controllers without extending the wiring.

E-Bike Thumb Throttle Compatibility
Compatible with many e-bike systems commonly found on bikes such as Vinxs, Lithium, Neptune and similar cargo e-bikes — we regularly fit and test this style of throttle in our Sydney workshop. Compatibility can vary depending on the controller, wiring and connector used, so we recommend comparing your existing part and connector before ordering.
This throttle uses a standard 3-pin SM-style connector, commonly used across many e-bike brands. It is not compatible with NCM e-bikes running Das-Kit electronics, which use their own proprietary throttle and connector — see our NCM Thumb Throttle (Das-Kit) listing for that system instead.
If your connector doesn’t match, adapting or splicing the wiring may be possible, but this should only be done by someone with the right electrical experience — it isn’t a plug-and-play fix. If you’re not sure, send us a photo of your current part or connector and we’ll help confirm compatibility before you order, or our workshop can fit it for you.
Safety & Installation Notes
Fitting this throttle is straightforward for most riders. If your current throttle already uses a 3-pin SM-style plug, it’s a simple swap — unclip the old one, clip in the new one, no rewiring needed. If your connector is different, you’ll need to adapt or splice the wiring, which should only be attempted if you’re comfortable and experienced working with your e-bike’s electrical system. If you’d rather not do this yourself, our workshop can fit it for you.
Adding or replacing a throttle can affect how your e-bike is classified under your state’s road rules, since throttle-controlled e-bikes are sometimes treated differently to pedal-assist-only e-bikes. This isn’t legal advice, and rules vary by state, so check with your state’s road authority if you’re unsure how this affects your bike’s road-legal status.
Frequently Asked Questions
Will this throttle fit my e-bike?
It fits e-bikes using a 3-pin SM-style throttle connector, common on brands like Vinxs, Lithium, Neptune and similar cargo e-bikes. Compatibility can vary by model, so check your current connector first, or send us a photo and we’ll confirm.
Is this the same as the NCM/Das-Kit throttle?
No. NCM e-bikes running Das-Kit electronics use a different, proprietary throttle and connector. This is a 3-pin SM-plug throttle for aftermarket controllers — see our NCM Thumb Throttle (Das-Kit) listing if you need the NCM-specific part.
What voltage range does this throttle support?
24V to 72V, covering the great majority of common e-bike controller setups.
Do I need to modify any wiring to install it?
Not if your existing throttle uses the same 3-pin SM connector — it’s a simple swap. If your connector is different, the wiring will need to be adapted or spliced by someone with electrical experience, or our workshop can fit it for you.
Is this throttle waterproof?
No IP waterproof rating is specified for this throttle. We’d recommend avoiding heavy rain exposure directly on the connector where possible.
Can Cool Bikes install this for me?
Yes — our workshop can check compatibility and fit it for you if you’d rather not install it yourself.
What's the warranty on this throttle?
7-day warranty against manufacturing defects. This warranty does not affect your rights under Australian Consumer Law. Damage caused by incorrect installation, wiring modification, misuse, accident or normal wear is not covered.
Specifications are as supplied and may vary slightly between production batches. Confirm compatibility with your specific e-bike or controller before purchase — contact us if you’re unsure.
