How to Adjust the Speed Limit?

DTTZH e-bikes are preset with a speed limit of 20 MPH (approximately 32 km/h). If you wish to experience higher performance speeds in a closed, safe, and private area, this speed restriction can be adjusted. Please contact us directly through Walmart messaging with your order number or screenshot. We will guide you step by step.

What Affects Range and Top Speed?

The actual range and top speed depend on rider weight, terrain, temperature, wind, battery level, and riding mode. Our estimates are based on ideal test conditions with a fully charged battery, average rider, and favorable terrain. Using only throttle mode will reduce the range, while pedal assist mode can help extend it.
