ElliptiGO bikes use industry-standard components that can be repaired or serviced by a technician who is trained to service bicycles. The custom parts are the frame, steering column, drive arms and adjustable crank assembly, which can also be repaired or replaced by a trained bicycle technician. Depending on your region, there may be a designated service location, or we will work with you to find a resource in your area who is willing to service or repair your ElliptiGO bike. Contact us first with any service issue so we can work with you to get it resolved as quickly as possible. You can reach our service department at [email protected] or by calling 888.796.8227.
