Give your smallest passenger something to hold on to.
The Child Safety Rails are a bolt-on tubular surround that frames the rear seat area on the U50, giving a child rails to grip and a defined space to sit within. The rails adjust from 280 mm to 400 mm wide to suit your child seat, and the 585 mm length means you can run a child seat plus a second young child riding alongside. They're built to work with the rear cushion as part of a family passenger setup.
Key features
- Front and rear guard rails plus side connector tubes form a full perimeter surround
- Ø19 mm aluminum tube construction
- Chamfered edges throughout for a safer, snag-free surface
- Adjustable width: set at 280 mm and opens out to 400 mm, so most child seats within that range will sit between the rails
- 585 mm of usable length: room for one child seat plus a young child riding alongside, or two seats if yours are narrow enough to pair
- Bolts to the rear carrier; pairs with the rear cushion
Fits: ENVO U50 family & cargo e-bike only. Mounts to the rear carrier. Best paired with the rear cushion. Using a child seat? Measure it first: it needs to sit within the 280 to 400 mm rail spacing.

Safety note: The Child Safety Rails give a passenger handholds and a defined space to sit within. They are not a restraint system and are not a substitute for a properly fitted child seat, a correctly worn helmet, or adult supervision. They are not crash-tested and should not be relied on for protection in a fall or collision. Always follow your local regulations for carrying passengers.
