My guess is that the rider was heading down the small hill when the vehicle involved drove into the bike lane to pass cars turning left, temporarily blocking their way. That move left the cyclist to plow into the back of the car, breaking off the fork and front wheel. Thankfully, he was wearing a helmet.
Please be careful out there folks. In a car, on a bike, or even just running along, remember that we all have families and friends to get home to.
