What bikes are the VOLT trainer compatible with?

The JetBlack VOLT™ EMS Smart Trainer is compatible or adaptable with most road and mountain bikes but may not suit some single speed, recumbent and some thru-axle configurations.

Compatible with:

• 130/135mm Quick Release (Q/R)
• 12x 140/148 Thru-Axle

Rear Wheel Size:

• Road: 650c, 700c
• Mountain: 24”, 26”, 27.5” and 29”


The JetBlack VOLT™ comes assembled with an 11 speed Shimano/Sram cassette and compatible body. The VOLT™ is Sram XD-R 12 speed compatible. Please see supplier to fit other types.

VOLT™ is compatible with XD-R but a XD-R freehub body is purchased separately

We have found some flat mounted disc braked bikes brands will not fit into the VOLT™ due to the disc mount and VOLT™ making contact.  

Brands we are aware of are:

  • Scott
  • Cervelo
  • Factor
  • Look
  • 3T
  • Fuji

We advise you check compatibility before purchasing if your disc brake is mounted on the flat rear stays of your bike. This issue is currently being resolved.
