    Instead of equipping the bike with a bunch of cogs, cables and added components, it’s split the powertrain out into two separate drives: a high chainring connected to a rear cog via a dedicated chain and a low chainring chained to a second rear cog on the same hub. All hardware is located on the right side of the bike, and the rider simply backpedals half a revolution to activate the switchable freewheel from high to low and vice versa.

    Neat idea! The shifting cog might be a unique part that’s hard to source but maybe they found a way to macguyver it from common parts, or worst case scenario one could slap a standard cog and some spacers on there in a pinch.
