Step 1: Pick Your Style

Step-over or step-through?

Same motors, batteries and fat tires. The difference is how you get on.

Step-Over

Classic frame · Max stiffness
  • Traditional top-tube frame
  • Stiffest frame for rough trails
  • Great for taller riders
  • Onyx, Obsidian, Basalt, Tor Plus
OR

Step-Through

Low frame · Easy on, easy off
  • Swing your leg through, not over
  • Easier for stiff hips, knees and backs
  • Easier stops and starts on hills
  • Onyx ST, Obsidian ST, Basalt ST, Mesa Plus ST
