The motor-mad plumber customised his month-old son's buggy so that he can race along at anything up to 50 mph.
Unfortunately, he's not allowed to take Baby Jake out at those speeds – so dad Colin takes the empty pram for a spin on his own!
The 33-year-old spent four weeks and £450 designing and making the pushchair, which has a 125cc motorbike engine hidden between the wheels.
And he even attached four gears to help the petrol-powered three-wheeler go up and down hills.
Colin, from Stamford, Lincs, stands on a platform and uses buttons on the handle to start and stop the engine. He has added accelerator and brake levers to control the speed and uses the handle to steer. There is even space for shopping and a handy drinks holder on the side of the pushchair.
"It is rather scary to drive but I've had lots of envious looks from mums and dads, especially when they are pushing their babies up hills," said Colin.
"It is really unstable when it goes at top speed and if you hit a rough bit in the road you are in danger of falling off, but so far I've managed not to crash."
He added: "Hopefully one day I'll be able to take Jake for a proper ride in it but I'm not sure if my girlfriend Charlotte would be very happy about that!"
Colin was determined to build the fastest pushchair in the world and to set a new Guinness record.
"You hear people complain about walking miles to push their new babies to sleep so I thought this would be a bit of fun," said Colin.
