Purchasing any Black Friday promotional model (OT05, OT07, OT16-2, or OT18-3) includes a surprise box, each containing a free accessory randomly assigned by the system. Buy 1 bike to receive 1 surprise box, buy 2 bikes to receive 2 surprise boxes, and so on.

The surprise box may include items such as a tail lock, tail light, inner tube, trunk bag, front basket, tail bag, helmet, brake pads, battery, and more.

If you purchase one of our Black Friday promotional models, you are guaranteed to receive an accessory (100% probability). However, the accessory is randomly selected by the system and cannot be chosen. Hope for your understanding.

To ensure efficient logistics and timely delivery of the e-bikes, the surprise boxes will be shipped separately from the bikes. Thank you for your understanding.

Promotional models are covered by statutory warranty and after-sales policies. Please note that free accessories included in the promotion cannot be returned, exchanged, or redeemed for cash. Accessories are available in limited quantities and offered on a first-come, first-served basis.
