The DirtyBike Industries (DB) Primary Chain Drive System is a strong upgrade for Sur Ron and Segway e-bikes to replace the factory belt system with something far more robust.
The stock primary belt can quickly become a failure point when exposed to dusty, sandy, or muddy conditions. Over time you will experience slippage and eventual failure, leaving you stranded with a costly repair on your hands.
DB’s robust primary chain system fixes this issue by eliminating the belt system altogether. Compared to kits with plated sprockets and hourglass-shaped chain links, DB’s straight-plate “endless” chain design offers far superior strength and longevity. The chain still features a master link for easy replacement without needing to remove the swing arm. This kit preserves your bike’s stock gear ratio.
219 Standard Chain – Lightweight and quiet. It’s much quieter than a 420 chain in our experience, but must be cleaned and lubricated often to maximize longevity.
420 X-Ring Gold Chain – Heavier but also heavier-duty. A long-lasting chain that doesn’t need to be cleaned as often at the expense of being much louder than a 219 chain. Requires DB 1mm sprocket spacer (included). This is DirtyBike’s proprietary aluminum alignment shim allowing for fine sprocket alignment and overall quieter operation.
