The Yellow Square scooter bag is a 5 L hard-shell handlebar bag that attaches at 4 points and comes off in 3-5 seconds. Its PU and EVA shell keeps its shape, while PU-coated polyester and rubberised zips keep water out. Inside are a main compartment and two mesh pockets for a phone, keys and documents.

Who it is for
E-scooter owners and cyclists who commute every day and want their phone, power bank, keys and water bottle on the handlebar rather than in their pockets. Riders who go out in any weather and on rough tracks. The design is unisex and suits adults and teenagers.
Who it is not for
Anyone planning to carry bulky items: 5 L and a 29 cm height are sized for small things, water or lunch. The body is rigid, so the bag cannot be folded into a pocket. If your scooter is not on the compatibility list, check that the handlebar has room for a 4-point mount before ordering.
