SWRXEarn Ebike Full Twist Throttle 12V–72V with 3-Pin SM Connector, Right-Hand 71" Cable

SWRXEarn's Full Twist Throttle is a right-hand, plug-and-play ebike throttle that fits 12V–72V systems and delivers smooth, ergonomic twist acceleration with a 3-pin SM connector.

This full twist throttle by SWRXEarn is built for compatibility and quick installation on electric bicycles and scooters. It pairs with controllers across a wide voltage span (12V–72V), uses a 3-pin SM-3Y connector (red+/black-/white signal), and includes a long 71-inch wire harness for flexible routing. The textured PVC grip and right-hand mounting hardware make it easy to swap into most standard 0.87-inch handlebars, while the durable plastic housing is designed for everyday use.

How easy is the installation for this ebike twist throttle?

Installation is intended to be straightforward: slide the grip onto the right handlebar, secure with the included hex wrench, and plug the 3-pin SM connector into the controller. The 71-inch cable provides extra reach for neat cable routing in most builds. No soldering is required if your controller accepts the standard SM-3Y connector wiring.

• 71-inch pre-wired cable for flexible placement
• Standard SM-3Y 3-pin connector (red+/black-/white signal)
• Includes hex wrench for right-hand handlebar mounting
• Fits 0.87-inch (22 mm) handlebars common on bikes and scooters

Will this throttle work with my ebike or scooter's voltage?

The throttle supports universal voltage compatibility from 12V up to 72V, so it works with many common ebike and scooter controllers. It’s intended to send a throttle signal rather than regulate voltage, so ensure your controller uses a matching 3-pin SM connector pinout. Confirm your controller’s throttle input pin order and voltage range before connecting.

• Compatible with 12V–72V controller systems
• Designed for controllers accepting 3-pin SM-3Y throttle wiring
• Signal wire uses white for throttle feedback, red for positive, black for negative
• Not a speed controller or voltage regulator—connects to controller input only

What are the design and durability features of this twist throttle?

The throttle housing uses heavy-duty polyvinyl chloride for impact and weather resistance in everyday riding conditions. The grip is an ergonomic PVC sleeve sized for common handlebars to provide a comfortable twist action. The full-twist mechanism is engineered for smooth throttle response while being compact and lightweight.

• Rugged PVC housing sized 7.13" x 4.45" for stable mounting
• Ergonomic PVC grip designed for comfort and control
• Full-twist mechanism for progressive acceleration input
• Weather-resistant construction for routine outdoor use

What does the kit include and what should I check after installation?

The package contains a wired handle assembly with the full-twist grip, a replacement grip, and an installation tool. After mounting and plugging the connector in, verify throttle response at low speed and ensure the wiring polarity matches the controller. Inspect the grip and housing for secure fastening and route the cable to avoid pinching.

• Complete wired handle assembly with 71-inch cable
• Replacement PVC grip and hex wrench included
• Check connector pin order and secure fasteners after fitting
• Test throttle action before each ride for safe operation

Who this is for: Riders, mechanics, and DIY builders updating or repairing electric bikes and scooters who need a reliable, right-hand full-twist throttle that works across a wide range of system voltages. It suits users replacing worn grips, retrofitting a controller that accepts an SM-3Y connector, or customizing a folding e-bike or scooter setup. If your ebike controller accepts the standard 3-pin throttle wiring and you use 22 mm handlebars, this kit aims to simplify installation while delivering consistent throttle feel.
