Top-tube phone case for 6.5 inch devices

The BONAEVER bag mounts on the bike’s top tube and holds Android or iPhone handsets up to 6.5 inches. A tough EVA shell with 3D die-casting keeps its shape, while a carbon-fibre outer layer resists abrasion. The seam-sealed zipper and waterproof shell block rain completely. Reflective detailing improves visibility after dark.

Steady protection on rough rides

Stiff sidewalls stop the case from flopping when the bike hits bumps or potholes. Internal items stay cushioned by the EVA structure, which absorbs shock and prevents the bag from pressing against the frame. The waterproof seal remains effective through repeated opening and closing. Capacity is large enough for a phone, wallet, keys and small repair kit.

Check mounting space and phone size

Verify that your top tube has enough clear length for the bag to sit without interfering with cables or knee movement. Confirm your handset fits the 6.5 inch maximum; larger models will not close properly. The design suits mountain, road, commuter and electric trekking bikes, but frames with unusual tube shapes may need extra strap adjustment.

Questions about this item

Does the EVA 3D shell and carbon-fibre outer keep the bag from heating up or rattling on long rides?

The stiff EVA 3D shell with carbon-fibre outer resists deformation and absorbs vibration, so contents stay protected and the bag remains stable all day.

What must my bike already have for this top-tube case to mount securely?

It straps to the top tube and stem, so your frame needs a horizontal or slightly sloping top tube with enough clearance for the straps to wrap around.

Will an iPhone 12 Pro or 13 Mini fit alongside a wallet and repair kit in the same compartment?

Yes, the case fits phones up to 6.5 inches — including iPhone 12, 12 Pro, 13, 13 Pro and 13 Mini — with room left for wallet, keys, snacks and tools.
