When the seas, CO2 levels, and temperatures rise, leaving the confines of your underground bunker as the only place to ride your bike, the Saris M2 Smart Trainer will keep you race-ready and connected. This is pedaling gadgetry in all the best ways, with full connectivity to your sensors, training apps, and bike. Its resistance is controlled electronically, with a smart hookup to your training programs, with all their built in maps and simulations. When those last roads crumble into the sea, know that you'll be happily cycling from the comfort of your impermeable fortress. (Or, just stay on top of the game with all the latest wizardry, should everything turn out okay!)
