Bo (pictured) is president and co-founder of Grown Men On Bikes (GMOB), one of the oldest groups at Slow Roll. Bo spent $1,300 getting a one-off low-rider custom bike build – but that’s just the start. ‘Once I go back in it’s going to get big,’ he says. ‘I’m going to get a custom seat, wheels, paint …’ The finished bike could cost around $3,000 – but would still be far cheaper than pimping a car. ‘This is much better. It’s a community. We party’
