The db0 (divided by nothing) 7 is an electric bike with a rear mounted motor designed by Rob Brady and team. The main focus was to design purposely for universal usage - male and female riders – and this dictated the purpose of the down-tube and the overall structure. The frame needed to allow for ease of mount and dismount for all riders. Designing around this universal purpose, the basic V shape becomes an iconic element of the design – using the central hub as the focal point of the bike. The center hub houses all of the electronics. The designers of db0 7 kept the overall read simplified – the design remains clean and not fussy. This clean focal point allows bike to stand out in the crowd.
The db0 7 equipped with the hub with stylized lights to show battery strength and power assist strength. These lights are not meant to be visible to the rider, they are more to highlight to the onlookers that this bike is something more than a traditional bike. Riders will gain information on their bike’s performance through a Bluetooth unit that will relay information to a db0 application on the rider’s smart phone. The rider can place their smart phone into a mount in the handlebar area for ease of use. The circular hub is the iconic element of the db0 7, in this case highlighting not only the technology but the overall lightness and simplicity of the bike by focusing on the empty space of the circle. This also stays within the db0 family aesthetic of elevating the electronic hub as the design focus.
The db0 7 has a distinct boldness to the tubing design. The tube design is purposeful in its cross-sections. While maintaining the bold aesthetic of the bike, they are functional in that the rear tube is much wider to allow for the housing the 36v battery pack and also as a structural support for the seat, while the front tube is much more slender, allowing for ease of entry onto the bike while still allowing room for necessary cabling through the tube. The seat adjustment is also unique. The seat support travels on the support tube within a rail, allowing for unique articulation points. As shorter riders lower the seat, the design also brings them closer to the handlebars. Rob Brady and team addressed structural concerns of seat support with concentric support components that complement the central hub and also strengthen the arrangement of the main V shape. The bike was designed to be as light as possible for an electric bike while maintaining consideration for manufacturing efficiency, i.e. a traditional bike assembly method of welded extruded aluminum tubing. The stylized cast aluminum wheels echo the simplistic design and mirror the play on empty space at the focal point of the bike. [via]
