Dirwin Pacer Ebike Description

Powerful, efficient, and innovative, the Dirwin Pacer can do it all! It's a versatile 2.2 inch tire touring/all-road electric bike built for street riding, recreational riding, commuting, and even gravel and hard-packed dirt trails.

With a fully integrated battery, lights, color LCD display, and a front suspension fork, the Pacer provides ultimate comfort and safety no matter what time of day or terrain you’re riding.

It features a step-thru frame for easy mounting and dismounting, and the 500W/1000W peak power system offers both a flexible 5-level pedal assist and throttle mode. With the Pacer’s Shimano 7-speed gear shifter and lightweight frame, the Pacer provides the versatility to cruise with power or get in a cycling workout in manual mode.
