Frequently asked questions

What is a Screecher®?

The Screecher®, is a carbon neutral, solar powered PMD (Personal Mobility Device). It is propelled by pedaling, electric motors, or a combination of both.

What are the key technical specifications and dimensions of the Screecher®?

• Charging: Solar power from the panel can charge the 48V lithium-ion battery in six hours*, or plug it in for four hours*. The battery will also charge through regenerative braking. • Pedal Assist: Screecher® can be powered by a combination of electric and human power. By selecting varying levels of power assist (1-5), the user can adjust how much assistance the motors provide. • Range: Screecher® riders can expect to travel about 20 miles in normal riding conditions on a single charge without pedaling. Any amount of pedaling will extend the life of your battery. Depending on a number of variables, the terrain, the amount of sunshine or your riding style, the range of The Screecher® varies. Tests have shown that reducing speed by a third can double your range. • Speed: 0-15 m.p.h. in five seconds. • Cruise Control: One touch cruise control, any braking cancels cruise control. • Utility: Large storage space. • Weight: ~Approximately 160 pounds, 73kg. • Dimensions: 34”W x 80”L x 65”H. • Tires: Pneumatic 20” front and 16” rear.

Do I have to pedal to engage the electric motors?

No, Screecher® may be used in pedal-assist mode, pedal-only mode, or operated by twist throttle.
