Howick Pump Track is listed as a playground at 33 Selwyn Rd in Howick, Manukau City, Auckland, with a Google rating of 5.0.
A pump track is a looped course of small rolling bumps and banked corners, ridden on bikes, scooters or skateboards by using body movement to keep momentum rather than pedalling or pushing. A good one has a smooth, well-kept surface, corners that flow into each other and room for riders of different levels. If you are new, ride a lap slowly first, keep your weight low and look ahead through the corner, and wear a helmet, with gloves and pads for younger riders. Regulars ride in the same direction as everyone else, leave a gap between riders and step off to the side rather than stopping on the track. Quieter times, such as weekday mornings, suit beginners, and a dry surface is safer than a wet one.
For families and young riders around Howick, Howick Pump Track on Selwyn Rd is a very highly rated local place to ride.
