Neil Farrow was able to purchase a used 20"
BMX bike for £50, which was in good condition
and was advertised locally. This proved to be a good
machine to base the project on however you could opt
for a new BMX bike instead of purchasing used.
According to Neil "if I were to build a gravity
bike again, I would seriously consider buying a new
BMX bike with some good v-brakes already fitted, and
perhaps some front suspension. I've seen them on sale
for about £120, which is a good deal."
Any ways here is how Neil built his Gravity Bike
