The PUBLIC D8 Electric bike can go up to 20mph with a range of 25-35 miles on a full charge depending on your riding conditions. To fully recharge your battery, you simply plug the battery into a normal outlet.

The PUBLIC D8 Electric bike is a dependable workhorse that can breeze you across town without breaking a sweat. Signature PUBLIC features include lightweight, durable chromoly steel-frame, aluminum chain guard and sturdy fenders, and a healthy dose of fun!

Public Bike Size Recommendations

A bike that fits properly is more fun to ride. The guides below offer size suggestion based on height in inches. If you have measuring tape, you may also determine your size by measuring your leg length plus one inch, which is your stand over measurement. For all bikes, we recommend at least 1 inch of space between you and the top tube of the bike.

When in doubt, contact our customer service team via email at customerservice@publicbikes.com or phone at 1-888-450-0123. For children’s bikes, smaller bikes are always easier for beginners.

*Please note some riders may be a little outside of these height range recommendations but prefer the feel of a larger or smaller bike. Stand over height measurement is not as important as how the bike geometry feels while it is being ridden.
