Today, in the U.S. alone, more than 7M people live with some form of unilateral weakness. Each year this number grows by half a million people. The majority of folks are either stroke survivors or amputees who have lost the ability to participate in common physical activities such as cycling. MonoMano was started to help these people regain the level of autonomy they once had. To do this we have created a detachable and adjustable one-handed control system that can be installed onto most cycles for riders who have the use of only one arm.
How does the device work?
To ensure the ease of one-handed use, we have designed all controls to mimic those currently existing on most standard bicycles. For steering, our device clamps onto the existing steering handlebar and allows users to control the bike from a centralized location, where a rubber handgrip is positioned for comfort. This means that the front wheel will be steered in the same manner as any standard cycle. For braking, we have outfitted our device with an adapted brake lever that simultaneously activates the front and rear brakes with the depression of the single lever. For gear shifting, we have incorporated two commercially available twist-shifters, in use on most mountain bikes, and oriented them in a manner such that the user can comfortably control both sets of gears without moving his/her hand.
How is the device installed?
To install or remove our device from the tricycle, the only tool necessary is a Phillips head screwdriver. The gear system can be switched between our one-handed and the original two-handed system quickly, by using a turnbuckle junction system that we have created. The brakes can be switched between the two systems by pulling the cables out of the existing levers and attaching them into our integrated lever, or vice versa. Finally, the handlebar can be removed loosening the clamp that secures our system onto the existing handlebars with a screwdriver. To further ease the installation and/or removable process, we have created a detailed user manual with our device. All together, either process should only require 5-10 minutes to complete.
The device has received stellar feedback from stroke survivors and able-bodied individuals alike, which has motivated Team MonoMano to provide this one-handed cycling system to all of those who need it.
