Bike Compatibility

We have found some Flat mounted Disc braked bikes Brands will not fit into the Volt due to the Disc mount & Volt making contact.  

Brands we are aware of are: Scott Speedstered, 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.

Insanely Quiet Indoor Trainer

Quieter than your drive-train.
Our testing sitting at 35kph on multiple indoor cycle trainers told us we are quiet. Watch our video for proof.
