The Santroll controller for the 27.5" VelectriX Ascent. It's a 36 V, 15 A unit, model WZKD3615KA-FSDOZ32-F4, and VelectriX's dealer listing marks it as the MY23 version.

  • 27.5" Ascent specific – programmed for this model and wheel size.
  • UART protocol – per VelectriX's specification.
  • 36 V, 15 A rating – suits the bike's 36 V system.
  • Genuine VelectriX part – part code VXAUS10556.

Not the same as the 29" controller

The 27.5" and 29" Ascent controllers carry different model numbers and wheel-size programming. Fit the wrong one and the speed reading and 25 km/h assist cut-off may not match the bike.

Fit and compatibility

Suits the 27.5" VelectriX Ascent only. The 29" Ascent takes VXAUS10314, and the 24" Hurricane takes VXAUS10483. Check the model number on your existing controller first, or ask Tune.

Tune's workshop can fit it and test the bike before you collect it.
