I work in the offshore industry and have now been told I’ve got a new placement on a boat. The boat is lacking room inside to set up a trainer. The only real option I have is to set it up somewhere that there is no power supply and I don’t think the crew be eager to help me get power to my new pain area. So that leads me to a trainer that doesn’t require mains power. Has anyone got any recommendations for such trainers. Internet is a no go so it just need to be compatible with trainerroad so I can get my lycra fix.
