We want to make KIDS BMX'S LIGHTER
And it all begins with my son who is 8 years old and loves to ride his BMX, but here's the thing, he weighs just 24kg and his Sunday Primer weighs a mighty 10kgs. I can see this extra weight is really holding him back as he learns to bunny hop and manual.
For an adult BMXer it's hard to imagine trying to do bunny hops or 180's or in fact any trick on a bike that is almost half your weight.
So a few months back I decided to rectify this and design and produce some lighter parts for smaller BMX's and the smaller/lighter rider.
I decided the easiest place to start was the forks and bars as we already make these for 20" BMX's so this should be a simple exercise in trimming things back.
So, I set about redesigning these parts forks with the intention of trying to save about one kilo overall against the same factory parts that came on his Sunday Primer.
My goal turned out to be fairly easy to achieve as weight of the stock bars (850g) and fork (1140g) combined was 1.99kg, which is pretty shocking as its much the same weight as the parts on an adult 20" BMX.
The bars and forks I designed are picture in this post, and they weigh collectively 1.06kg. So with just these two titanium components I managed to knock off just under a kilo from his bikes overall weight.
On a roll I decided to continue to see where this weight loss programme could go and see if I could shed even more weight by designing and building a 16" titanium frame.
But this part was a little disappointing though as a titanium frame only manage to save 0.5kg on the original steel frame.
His original Sunday Primer weighed in at 9.72kg, so this little beauty, the complete titanium frame, forks and bars weighs 8.29kg.
In short, this project worked it created a 16" BMX that is 1.5kg lighter than my sons original 16" BMX and built a sturdy bike that hopefully my son will have more fun on learning tricks.
