Human Electric Trike Thesis

Design of an electrically assisted human powered trike

6/27 Update

Spent past week working on design of front and rear suspension. Designed rocker arms to transmit front suspension travel to coil over shock. Designed rear swing arm with 2.5 inches of upward travel and ~ 1.5 downward travel.


Selected sprockets to give 19.2:1 final drive reduction from motor to rear wheel. Started preliminary frame design, leaning towards using 1.25″ X 2.5″ X 1/8″ wall 6061 tubing bonded and riveted together.
