Support plans are available for the GURU fit bikes from Kalida. If I recall correctly, Kalida were the original design team for the GURU fit bike - or have been involved in their design for quite awhile. Check the link above and there's a support email you can reach out to with questions.
Have had their Gen 2 bike for 6 years - it gets very heavy use and has been impressively solid. Be ready for belts to go out from time to time (I think I've had to replace 3-4 belts in 6 years). 5 minutes to replace once it arrives in the mail.
