If you do a lot of commuting or just like to cruise around town, a 20" BMX bike can be slow going. That's when bigger is better! These big bikes or UTB's (Urban Terrain Bikes) eat up the miles, but still have roots in BMX by keeping things clean and simple. Whether you're flying through the streets, ripping down alleys and shortcuts, hopping curbs or just popping a timeless wheelie, a bike with bigger wheels is a more effective tool for the job.
