Jerbor Full-Twist Throttle Grip for Qlife Racer/Cityone/Trike — 3-Pin Waterproof, Anti-Slip

JERBOR Full Twist Throttle Grip is a direct-replacement rotary throttle handle engineered to restore precise speed control and reliable waterproof performance on compatible Qlife Racer, Cityone and Trike electric bikes.

If your e-bike’s throttle is worn, unresponsive, or weather-damaged, this JERBOR full twist throttle grip offers a drop-in solution made from durable rubber and metal. Designed specifically to fit a long list of Qlife models, it reconnects your right-hand throttle control with a standard 3-pin waterproof plug and an anti-slip textured surface for improved handling.

Which Qlife e-bikes does this throttle fit?

This throttle was developed as an exact fit for many Qlife models, so you won’t need custom wiring or adapters. It is compatible with Racer lineups, several Cityone variants, and both Trike models listed in the product details.

• Fits Qlife Racer, Racer 27.5, Racer Fat Tire, Racer Plus Fat Tire
• Fits Qlife Cityone ST, SO, 2.0, Step Over 2.0, Stepover Ultra
• Fits Qlife Trike and Qlife Trike Plus

How does the throttle improve ride control and responsiveness?

The full twist design provides intuitive, graduated acceleration — a small rotation results in a proportionate speed change. The mechanism is tuned for quick response to rider input while the textured rubber reduces hand slip and transmits less vibration to your grip.

• Full-twist rotary action for smooth speed modulation
• Anti-slip rubber texture improves grip in wet or rough conditions
• Metal internals for consistent tactile feedback and longevity

Is the throttle weatherproof and built to last?

The throttle uses a standard 3-pin waterproof connector and materials selected for wear resistance, helping it resist dust and light rain. While not a guarantee against all exposure, these features lower the chance of electrical or mechanical failures during everyday commuting.

• 3-pin waterproof connector for moisture resistance
• Durable rubber exterior with metal components for strength
• Designed to resist road wear and surface abrasion

How easy is installation and what’s included?

Installation is straightforward: the grip mounts onto the right handlebar and plugs into the existing 3-pin throttle socket — no special tools or modifications are required for compatible Qlife models. The package includes one full twist throttle handle and a 30-day warranty window for initial issues.

• One full twist throttle handle in the kit
• Direct plug-in 3-pin connector for compatible Qlife wiring
• Quick installation onto standard right-side handlebars

Who is this for: Riders and technicians who own Qlife Racer, Cityone or Trike e-bikes and need a reliable replacement throttle that restores responsive acceleration and better grip. It’s aimed at daily commuters, recreational riders, and service shops seeking an OEM-style swap for worn or damaged right-hand throttle controls.
