Ответ SkatePro: Hi Lorene,
Thank you very much for your review.
I'm sorry to hear that the lock nuts of the scooter weren't tightened up in a proper way. We receive these scooters from our manufacturer and it happens sometimes that in the factory, it hasn't been completely tightened up. It's always recommendable before any skate ride, to check all the bolts and nuts to make sure that all of them are ok.
If you have any questions about it, we would be glad to answer them!✌
