RECUMBENT POSITION proritizes comfort by removing pressure from the buttocks and wrists while fully supporting your back, making long rides blissssful. Head up display offers panaramic landscape viewing while riding.
BACKREST spine modeled after the human spine, the ribs support and cradle the body, while providing ventilation and shock absorption. The replacable ribs have the potential to be tuned to your specific body needs or perhaps to your specific esthetic styling or color choices.
ADJUSTABLE SEAT accomodates a wide range of riders, from 50th percentile female to 95th percentile male. (approximately 5'4" to 6'3" or 162cm to 190cm)
ADJUSTABLE CRANK BRACKET (BB) fine tunes you leg length adjustment, or tweaks your fore-aft weight distribution to enhance riding comfort or performance.
AERODYNAMIC recumbent position reduces your frontal profile, cheating wind resistance, increasing cruising speed.
TERRAIN tamed with fat tires to smooth out the bumps, float over snow and sand, and offer a cushioned ride, especially important to recumbent riders (who can not count on leg absorption to smooth out the bumps). Fat Tires chosen to accomodate all road and trail surfaces, in all climates, in all seasons, with the ability to tune the tire pressure to your specific riding conditions.
POWER AND EFFICIENCY is where it starts. With a carbon fiber frame and seat to keep stiffness up and weight down, and a ridgid backrest to push against when climbing hills, the bike was designed to be easily human powered even with a motor and dead battery onboard. With the optional front and/or rear hub motor and batteries removed, the machine becomes a light weight human power speedster, unencumbered by e-bike legislation.
Laugh at stiff winds and steep hills with a power package. Powerful 500 and 750W hub motors and 48V, 20AH li-on battery, with expansion potential, get you to your 50km destination without fear. This bike is meant to be pedaled, and so offers pedal assist, but also offers an throttle (that may be disconnected if desired), that will help on uphill starts, getting quickly up to crusing speed, or get you home in the case of an emergency that could prevent you from effective pedaling.
SAFETY considerations include eye to eye contact with surrounding drivers, making the riding height ideal for this purpose. When stopped, both feet are planted firmly on the ground, making a tipover nearly impossible. 180mm front and rear mechanical disc brakes, coupled with the fat tires, lead to impressive braking performance while allowing for simplified brake repair and maintenance. High power Headlight, Taillight and signal lights are available accessories.
AESTHETICS of the design were inspired by nature with bio-mimicry elements such as the backrest and fender designs, the latter being akin to fish scales or Armadillidiidae. Other design aspects included the use of phi or the Golden Ratio.
