Hi Christina, Oh no! I'm so sorry to hear of the issue with the brakes! We can definitely help with a fix. First, would you mind sending over a photo of the front of the bike? -Laura @Guardian Bikes

Delivery disaster & missing bolt

The experience was really poor. The delivery driver backed into our fence and broke several parts. They drove away but my neighbors witnessed it. The other issue was a missing bolt on the bike tire. We had to go to 3 different hardware stores / bike shops to try and find one that was the same so we didn't have to order it all over again and wait

Horrible service

Horrible service. Bought the bike for a birthday present and waited months to receive my order. Each company email update was nothing more than a strategic delay excuse.
