The ROCKBROS Hard Shell Bag gives your phone, keys and gear a crushproof home on ANY ride. Two models, one system: the B60 straps to a bike's top tube with three hook-and-loop straps; the B62 (2L) hangs on a scooter or folding-bike stem with a four-point strap mount. No tools, no brackets.
Sold as: one (1) bag in your choice of model.
ROCKBROS · Hard Shell Storage
Phone, keys, wallet, charger — they need to live somewhere when you ride. The ROCKBROS Hard Shell Bag straps to your e-bike's top tube or your scooter's stem in seconds, and its crushproof EVA shell keeps everything inside safe from drops, weather and road vibration. One bag that moves between every ride you own.

Bike + Scooter Ready
Hook-and-loop straps mean no tools and no brackets: the B60 cinches to a bike's top tube with three straps, and the B62 hangs on a scooter or folding-bike stem with a four-point mount. On or off in under a minute.
That's the trick — one system covers your whole garage: the e-bike for weekend cruises, the scooter for the daily run.

Armor for Your Gear
Three layers of protection: a water-repellent textured PU surface, a compression-absorbing EVA middle shell that holds its shape under impact, and a wear-resistant fabric lining — your phone screen doesn't meet your multi-tool at every pothole.
The laminated two-way waterproof zipper closes tight against rain and road spray, so sudden Florida weather doesn't soak your electronics.

Organized Inside
Internal mesh pockets keep your phone, cards, keys and cables from rattling into each other, and the organ-style opening holds its shape — open it at a stoplight and nothing spills out.
The B60 Small swallows a phone, keys and a wallet. The B62 Large (2L) adds room for a big phone, earbuds, tools and snacks for the long way home.

Looks Right on Any Build
The B60's diamond-shaped narrow lower edge gives it a knee-clearance profile — no leg rub when you pedal. The carbon-fiber texture matches a blacked-out moped build instead of fighting it.
The silver ROCKBROS logo is reflective, throwing headlight glare back at drivers — a little extra visibility every night ride.
Sold as one (1) bag in your choice of size. No tools needed to mount.
