In his own words, "If i were to start riding again from scratch, the Madmain would be my ideal entry level set up.." Integrated headset, 25/9 gearing, sealed mid BB, super short back end, and nice high wide bars. In fact, Harry actually regularly rides a Madmain complete bike in his home town of Liverpool. In order to sign off on the Madmain, Harry was involved in every tiny detail of the design from start to finish. He wanted to be proud to put his name on a product he hoped could inspire a generation to get involved in BMX. The Madmain line of completes sticks to Mafia's long running ethos as well as Harry Main's vision for BMX; providing great quality, long lasting bikes at affordable prices
