Bosch Intuvia
An intuitive display that enhances your e-bike experience. It provides essential ride data like speed and battery status, features user-friendly controls, and includes a USB charging port for on-the-go device power!
Gates CDX Belt Drive
Spend more time riding with the low-maintenance Gates Carbon Belt Drive, which outlasts traditional chain systems and requires no cleaning or lubrication.

Rider Reviews
What People Are Saying
I've been riding the GSD for about two years now and I've done about 8,000 miles with it, most of them with my son at the back. This bike is one of the best buys that I've made, ever! It's super quality, with the dual battery there is not range anxiety and, basically, it's really fun to ride.
Bryan
It’s an excellent bike. The 20-inch wheels and low-standover frame keep the weight close to the ground, minimizing the bike’s propensity to rock side-to-side when you make a sudden turn with added weight over the rear tire. The suspension fork makes the ride even smoother and the bike even easier to control when you encounter rough pavement or gravel.
