'lunartic' by luke douglas 'seoul cycle design' competition shortlist revealed

‘lunartic’ by luke douglas

‘lunartic’ by luke douglas from the uk is one of the shortlisted design entries from more than 3000 participants in our recent designboom competition, ‘seoul cycle design competition 2010‘, organized in collaboration with seoul design foundation.

designer’s own words: what? ‘lunartic is a compact urban bicycle concept exploring the unique combination of different wheel sizes, a toothed belt drive and hubless rear wheel. ‘lunartic’ places itself in a niche between existing bicycle solutions: compact without folding, easy to ride and handle, stylish and comfortable

why? the gyroscopic effect of a large wheel helps it travel faster and more contact with the road provides a stable and comfortable ride, whereas small wheels save space, weight and are more maneuverable. belt drives are clean and maintenance-free and a hubless wheel creates a whole new space, as well as an intriguing aesthetic.

how? the combination of these features is a new balance of ride quality, space saving, style and convenience. moving the working parts back, inside the rear wheel shortens the wheel base but maintains large wheel performance. there is no sacrifice to conventional or efficient geometry apart from a low center of gravity and stand over height.

  • Great proto and really happy to see someone that have spent hours manufacturing his vision.

    I do think front wheel size it’s the matter (stability due to posture / force applied problems probably – if you are a biker you have surely experienced it already).

    Anyway, I hope you will get the chance to develop further your concept and have a great fixed gear real bike soon. Good night and good luck.
