On the pedal side of things, each rider has a Schlumpf high speed planetary drive at their
disposal to allow them to pedal at speeds up to 30 mph, while still being able to create
some serious torque at low speeds. Each Schlumpf drives a 16T White Industries
Freewheel, which spins a common jackshaft that turns a chain that runs to a 7 speed
cassette in the rear.
Huge thanks to Belmont Textile Machinery Company for allowing us to use their
facility for the build!

Thanks to SBM Solar of Concord, NC for their fantastic lightweight, high-efficiency
solar panels.

Also a big thanks to RZR Lighting for their super bright, efficient, and very lightweight
LED light bars.

We are now upgrading to a more powerful, 10,000 watt peak Mars Brushless Motor,
more energy-dense batteries, and a high-output charger.
