Confirm fitment before ordering
You must confirm fitment with Projekt46 before placing your order. Send your exact bike model, version, production date (if known), and clear photos of the original throttle and connectors to WhatsApp: 816-904-9360 or Projekt46bikes@gmail.com.
-
LeonX: version 1.0 only. This option is not offered for later LeonX versions.
-
Qronge: factory full-twist version built before October 2026 only. Other throttle configurations and later builds are not confirmed compatible.
-
Drax Apex/ Z03 Pro 10kw 72v Models only
Plug-and-play fitment is not guaranteed. Factory connectors and wiring can vary on bikes built before or after October 2026. We do not have a test bike available to verify every version. A matching model name or production date alone does not confirm compatibility.
Full-twist throttle upgrade
The Projekt46 Surron-style throttle offers full-twist control, Hall-effect operation, a carbon-look housing, and upgraded aluminum internals.
What’s included
- Surron-style full-twist throttle for standard 22 mm handlebars

Before installation
Verify connector shape, pin count, voltage, ground, throttle power, throttle signal, mode, and ignition functions before connecting. Disconnect battery power during installation and test operation with the drive wheel safely off the ground.
