Bicycle handlebars that double up as a lock

Student Jaryn Miller has designed a set of removable handlebars that separate into three pieces to become a lock.

The Senza bike lock comprises a central section of handlebar, which always remains in place on the frame and two outer sections that can be removed and fixed together to offer a larger alternative to a standard D-Lock.

According to the designer, smashing the lock, which leaves only the central section of handlebar in place, renders the bike virtually unrideable, but the claim ignores the fact that many urban cyclists ride with chopped handlebars by choice.

Bicycle security is a popular subject for design students. Recent Royal College of Art graduate Dominic Hargreaves is gaining a reputation for his imaginative cycling-related designs.

Following his award-winning ultimate cycle lock Hargreaves’s most recent project is a full-size bicycle that can be wheeled along when folded.

The ‘Contortionist’ has hinges along its aluminium frame allowing it to fold in on itself. Its two full-size wheels remain free, so the folded bike can be wheeled along using the handlebar. This allows it to be carried on to the Tube, buses and taxis.

Cheap insurance for folding bikes

Cycle insurance from the ETA offers a 40 per cent discount for folding bicycles of all kinds. Every policy includes new-for-old replacement and accidental damage (including at race events), third party insurance (in the case of an accident you may need to seek compensation or even deal with a claim by someone else), personal accident cover and if you breakdown, they will even come out and get you.
