S500 Utility Quad Technical Specifications

Frequently Asked Questions

Is the S500 classified as a traditional bicycle?

No, the S500 is an Electric Utility Quad (four-wheeled vehicle). It features a stable four-tire design, a spacious sitting bench, and a rear cargo box. It operates completely via electric throttle control rather than traditional bicycle pedals, making it ideal for riders searching for extra balance, stability, and utility.

How do Hill Hold and Hill Descent Control help me?

These are premium safety features usually found in modern cars. If you come to a complete stop on a steep hill, Hill Hold automatically locks the vehicle in place so you don't roll backward when you let go of the brakes. Hill Descent Control automatically manages motor braking when going down steep paths, keeping your descent slow, controlled, and safe without riding the brake levers.

Can I attach a trailer to the back of the S500?

Yes! The S500 comes equipped with a dedicated trailer hitch setup on the rear frame. We recommend using a standard 2-inch receiver adapter, which allows you to hook up small utility trailers to tow extra gear, yard tools, or camping equipment.

How does the NFC unlock function work?

Instead of a traditional metal key that can get lost on trails, the S500 utilizes secure digital NFC technology. You can quickly turn the vehicle on or off simply by tapping an NFC keycard against the dash or by syncing your compatible smartphone to the vehicle.

Is the seat adjustable for multiple family members?

Yes. The comfortable, wide-set saddle is mounted on a sliding track system that allows you to shift the seat forward by +30 mm or backward by -70 mm, ensuring a customized, comfortable leg reach for adults of various heights.
