The DaVinci Viaggio 350w TrailRider, is an electric powered front wheel attachment fits most rigid frame wheelchairs.
350 watt high torque gear drive motor with high power programmable 12fet controller.
The distance travelled depends on a number of factors speed, weight of rider, terrain, temperature, however generally a 80kg rider on reasonably flat terrain at about 10 to 12 mph could get up to 20 miles on a 10ah 36volt battery.
However on rougher terrain, there is much more resistance and more power and energy is required to travel the same distance so the fat wheel on this TrailRider gives greater grip.
