We have recently sourced these stunning M3i Black Keiser Indoor Cycles.

Sourced from a spinning studio, these bikes provide a fantastic indoor cycling experience for the user and at the same time will look aesthetically pleasing in your home or commercial gym. 

We have 20 of these bikes in stock, all are fully working and in fantastic condition, these have been used in a commercial studio.

They come full serviced.

Long established as one of the best manufacturers of indoor bikes on the market, the M3i is the result of over a decade of research and development by Keiser in collaboration with trainers and users in some of the largest clubs worldwide.

Built from quality-tested, corrosive-resistant materials, with a magnetic resistance that won’t wear out, the M3i’s main selling point is its unbeaten durability: this machine will last and last.
