Groceries, laptop, a change of clothes: With the ISTOS SideRail, you can attach panniers to the sides of the FlexCarrier on your HEPHA Generation 8 e-bike. The rail gives each bag a fixed spot. This keeps it stable, prevents it from sliding back and forth, and keeps it clear of the wheel and fender. The SideRail can hold up to 10 kg per side. You can install it yourself in about 10 minutes – the tools are included.

With the ISTOS SideRail Kit, you can retrofit your FlexCarrier for side panniers. The rail is screwed onto the side of the rack, where it holds your bag securely in place and keeps it clear of the wheel and fender. This ensures that the bag stays where it belongs, even on bumpy trails.

- Quick to retrofit: Fitted in 5–10 minutes. We include the 8 mm spanner, and you don’t need an adapter.
