The DK Deka 20” is the best bang for your buck bike on the market for that rider graduating to the full-sized class.
Check out the other guys and do the math, this is the cheapest you will find this bike in Perth, and no "club" price BS.
With a shorter 19” top tube length and lower “stand over” height, the Deka 20” is sized down for smaller riders, but features 20” wheels for real-world BMX action. Deka comes packed with features that make it look, feel and ride like it costs much more. 25 x 9t gearing, Padded rail seat and on-trend 8.25” bars keep you riding tall. DK grips and PC pedals are a nice touch. To top of Deka, a high-tensile steel frame, supported by chromoly 3-piece cranks make for a durable, quality ride at a price that is easy to get a hold on.
