The NuDrive EVO lever drive wheelchair propulsion system can be added to your conventional manual wheelchair in seconds. With the NuDrive EVO, you get more power with up to a 2:1 mechanical advantage. This makes ascending inclines far easier. Grip the levers close to the hub for more speed or close to the ends for more power. The NuDrive EVO lever drive is also a great way to get exercise. The ergonomics of pushing the levers is less damaging on your shoulder joints as compared to pushing conventional handrims.
The NuDrive EVO's patented design consists of two wheel adapters and a pair of drive units. The wheel adapters will fit your existing wheels and can be added or removed in seconds. With the wheel adapters in place, the drive units can be attached in an instant. Many people who use the NuDrive EVO leave the lightweight wheel adapters permanently on their wheels.
On declines, speed can be controlled with the NuDrive EVO's Cool Stop® braking system. Built by a leading manufacturer of brakes for mountain bikes, Cool Stop® brakes provide better control and more safety when on uneven terrain.
There are no heavy motors or batteries and no worries about getting batteries charged every night. Best of all, NuDrive EVO is a lightweight, "go-anywhere" mechanical solution for your exercise and propulsion needs.
