The side hacks are an ongoing project of JP's
A few details on his website here:
http://bmxsidehack.co.uk/The Plan is to get 4 of them on the Gate for the next 'Pride of Essex'
I have ridden JP's 1'st one and all I can say is racing them would be nuts, not least coz it's friggin hard work.
I was thinking of doing the pedelling and getting my 11 year old in the hack. The boy seems up for it
Anyway details from JP
All the best Steve Gilbert
