"I thought she was dead. There was blood coming from everywhere. She was hysterical, screaming at the top of her lungs.
"I had to check she still had arms and legs because the speed she was taken was so quick and she'd just been flattened by this bike."
Father Matt ran to pick up Lucie, who was covered in blood, with cuts to her face, head, hands and knees.
A man in his 20s is due to be questioned by police after coming forward following the incident being reported.
She was taken to Blackpool Victoria Hospital A&E where her parents were relieved to learn she had not broken any bones. She was, however, left with head injuries caused by the bike's tyre.
The video footage shows Lucie following her mother Lauren out on to the pavement on Monday afternoon before the cyclist appeared from nowhere.
Ms Howarth said: "I was heading towards the car and Lucie was following me.
"As soon as Lucie stepped out, he got her. He must have been going some speed because I didn't see him.
"Matt jumped over the wall and got to her and swept her up.
"We didn't know what kind of injuries she had suffered, we just knew we had to get her straight to the hospital so we put her straight in the car.'
The family say the cyclist made no efforts to check how Lucie was and Ms Howarth claims he swore at her before getting back on his bike and cycling off.
"He was on the floor with his head on the pavement," said Ms Howarth. "I was expecting him to say 'I'm so sorry, is everyone okay' or something like that but there was nothing.
"As soon as he got up he started swearing at us, as if it was Lucie's fault that he had hit her. The next thing we knew he'd gone and we've not heard from him since.
"I know it would have been a shock for him but it would have been nice for him to put a note through the door to check how she is. For all he knew, she could be dead."
Lucie is now recovering at home. While her physical injuries will heal relatively quickly, the family fear the mental scarring may last much longer.
Ms Howarth, a carer currently on maternity leave, said: "For a three-year-old to go through something like that is a big thing.
"She's now very nervous of bikes, and we've had to tell her that daddy has got rid of the bike to make her feel better.
"But she won't walk across the pavement to the car at the moment, we have to carry her, because she's scared of being hit. She's been really brave though, we're really proud of her."
Ms Howarth, who is also mother to daughters Katie, six, and eight-week-old Ellie are now hoping to raise awareness of cyclists who ride on pavements despite it being against the law.
She added: "I would never have walked out of our house before and looked left and right as if I'm crossing a road.
"It's a pavement so you're just aware if there's people walking about but you never expect something like this to happen right outside your home.
"The speed he was going on that bike in a residential area with young children around is dangerous and this happened to Lucie out of nowhere.
"People need to be aware that cyclists can be dangerous drivers too."
A man in his 20s has since contacted police in connection with the incident and is due to be spoken to by officers tomorrow.
PC Joanna Mills of Lancashire Police said: "There are a number of offences that will be discussed with this man - riding on pavements and dangerous cycling.
"For a three-year-old this isn't a pleasant experience when you're just walking from your home to your car.
"Lucie is lucky she's escaped with only scrapes and bruises. It could have been a lot worse."
