The First Aftermarket Belt Drive For Bikes

Replace your bike chain with an exceptionally durable, quiet, and low-maintenance belt drive.

Why The Split Belt™?

A belt drive is the smart replacement for a chain on your bicycle. We make the first spliced belt drive that can be retrofitted onto most frames and riveted back together.

There’s no grease, no rust, and no worries. With no metal on metal contact you get a smooth, responsive pedal feel that puts new life into your ride.

Reinforced with carbon fiber strands, it’s as strong as your chain and lasts way longer. Stop replacing parts every season and tinkering with your drivetrain. Spend more time riding.

What Bike Enthusiasts Are Saying

"This innovation of a split belt, which is also suitable for retrofitting, represents true progress if the operating principle proves to be successful. It eliminates the drawback of having to modify the frame in order to change the belt, while retaining the already familiar advantages of the belt drive."

My bike with the Split Belt is so quiet, so smooth, so clean, and so fun! It has been 9 months of continuous riding. I don’t own a car so I commute and do errands on my bike every day (over 5000 miles) and I still get a smile on my face when I jump on my bike and start to pedal.
