What If Batman Had a 4 Wheel Bike? 🦇 Custom Differential Build

In this video I show the progress of my Bat Bike inspired 4 wheel tilting bike build. The rear drivetrain uses a custom differential with two 520–44T sprockets. Power is transferred to both rear hubs using dual chain drives. Both rear swing arms are built with pivot points aligned to the differential shafts using bearings, which keeps the chain tension constant even when the swing arms move. Rear hubs, swing arms and the differential system are now completed. More parts of this custom Bat Bike build are coming soon.
