What the Lekkie Pacemaker Is

The Pacemaker is a precision-engineered full-twist electric bike throttle, developed over five years by Lekkie specifically for electric bikes and motorbikes. It mounts under your bike's shifters and delivers smooth, progressive control through a quality CNC-machined full twist mechanism — a more intuitive input for many riders than a thumb-paddle throttle, especially on high-torque mid-drive builds like the Trailblazer's Bafang M560/M600 system.

Why Riders Upgrade to a Full-Twist Throttle

A thumb throttle asks you to modulate power with one finger, off to the side of your grip. A full-twist throttle uses the same wrist motion riders already know from motorcycles and other twist-throttle vehicles, which many find gives finer, more natural control — particularly useful on a high-torque mid-drive where smooth, progressive power delivery matters for technical climbing and low-speed control.

The Pacemaker's grips are also built to take a hit. The lock-on design and full plastic end cap are engineered to survive impacts and bike drops without losing function, and the softer stock compound can be swapped for the firmer grey grip set when you want a different feel.

Fitment & Installation

The Pacemaker is designed to sit comfortably under your existing shifters without interfering with gear changes, and installation is straightforward for anyone comfortable with basic e-bike component swaps — the throttle and matching left lock-on grip both use a lock-on design for a secure fit with no slipping, even in wet conditions. Full installation notes are included with the throttle; HPC's team can also help walk through fitment on a Trailblazer or other Bafang mid-drive build.

Built to Last Through Real Riding

Every component on the Pacemaker is electrically sealed, which matters more than it might seem — a throttle that fails or corrodes after a wet ride is more than an inconvenience on a high-power build. The lock-on grip and throttle system stay put under vibration and hard use, and the full plastic end cap is specifically designed to protect the unit through the kind of bike drops that happen on technical trail rides. Lekkie backs the Pacemaker with the same standard the company applies across its lineup: exceptional, robust components with no shortcuts.

Beyond the Trailblazer and other Bafang-powered HPC builds, the Pacemaker's twist-throttle design also works across Sur-Ron, Talaria, and other electric mobility platforms that use a twist-throttle mount — making it a versatile upgrade if you run more than one high-power machine and want a consistent throttle feel across all of them.
