🚴 Why You’ll Love It

Rear-Wheel Drive with Differential

Power is delivered to both rear wheels for better traction, tighter low-speed control, and safer turning than front-wheel trikes.

Super-Long Range (Dual Battery Option)

Go farther with a second UL-certified 48V 17.5Ah battery for up to ~137 miles per charge (riding at low PAS).

Light, Foldable, Step-Thru

Easy on/off, easy storage. The hydro-formed aluminum frame folds for transport and fits riders from about 4'11"–6'5".

Confident Stopping Power

Tektro hydraulic disc brakes with motor cut-off stop all wheels for stable, predictable braking.

Smooth & Comfortable

20" × 3" fat tires add cushion and grip; an 80 mm suspension fork tames bumps on pavement or path.

Smart Assist & Bluetooth

Torque-emulating PAS with 5 levels, on-demand thumb throttle, and a color LCD with Bluetooth for diagnostics and app features.

Safety First

System is UL 2849 certified; batteries use premium LG/Panasonic cells with BMS protection for longevity and safe charging.
