The Mokwheel Basalt uses a 6061 Aluminum Alloy with an internal battery layout, designed for all-terrain use, while the Trek Powerfly features an Alpha Platinum Aluminum frame with a Removable Integrated Battery (RIB) system. Each design offers its own benefits, but the Basalt’s integrated approach minimizes exposure to elements and enhances aesthetic appeal.

Brake System and Tires

The Mokwheel Basalt is equipped with TEKTRO HD-E350 Hydraulic Disc Brakes, and the Trek Powerfly 4 Gen 4 with Tektro HD-M275 hydraulic disc brakes, ensuring reliable stopping power in various conditions.
