SWRXEarn full twist throttle: a 7/8" (22mm) plug-and-play ebike throttle compatible with 12–72V systems and many popular electric bike and scooter models.

This compact replacement throttle delivers smooth, linear acceleration and rugged weather protection for riders updating or repairing right-handlebar controls. Designed to fit a wide range of brands — including Jasion, Qlife, Happyrun, Macfox, Freego, Heybike, Lectric and others — it arrives as a complete kit for quick installation so you can get back on the road without soldering or complex rewiring.

How easy is it to install on my electric bike?

Installation is straightforward: slide the throttle onto a 7/8" (22mm) handlebar, connect the 3-pin plug to a compatible controller harness, and secure the mounting hardware. The package includes grips and basic mounting tools for a single-person install.

• Includes 1 full twist throttle, 1 pair of rubber grips, 1 allen key, and 4 zip ties.
• Fits standard 7/8" (22mm) handlebars — no adapters required for most bikes.
• Plug-and-play 3-pin connector; verify connector type and wire order before connecting.
• Simple right-handlebar mounting; tighten clamp with allen key provided.

Will this throttle work in wet or dirty conditions?

The throttle features an enhanced sealed design to resist water ingress and reduce the risk of shorts during damp or rainy rides. While it improves reliability in wet conditions, routine inspection and correct installation help maintain long-term performance.

• Advanced waterproof sealing protects internal electronics from moisture.
• Durable exterior construction reduces risk of contamination and corrosion.
• Sealed connector and housing minimize short-circuit risk in damp conditions.

How does the throttle feel and control power delivery?

Engineered for linear response, the full twist throttle provides predictable, smooth acceleration with minimal dead zone. An integrated rolling bearing reduces friction, giving a consistent feel and faster response when you need quick speed changes.

• Linear power output for gradual speed increases.
• Rolling bearing lowers friction for a smooth twist action.
• Rapid mechanical response for confident throttle control on climbs or city rides.

Which bikes and voltage ranges is this compatible with?

This throttle supports a wide voltage window (12V–72V) and is compatible with many common electric bike and scooter brands. Before purchasing, confirm your handlebar diameter and controller connector routing to ensure plug compatibility.

• Compatible with Jasion, Qlife, Happyrun, Macfox, Freego, Heybike, Lectric and other brands listed.
• Works across 12V–72V systems — suitable for most consumer ebikes and scooters.
• Designed for 7/8" (22mm) handlebars; measure your grip diameter prior to ordering.

Who is this product for? Riders who need a durable, weather-resistant replacement or upgrade for their right-handlebar throttle will benefit most. It’s aimed at DIY mechanics, ebike owners with compatible bikes and scooters, and anyone wanting a quick, plug-and-play throttle swap that improves control and reliability without complex wiring. If you require brand-specific wiring diagrams or are unsure about your connector, verify compatibility with your controller or consult a technician before installation.
