As for brakes, Mountain Bike Calipers work well on cruisers, road bike calipers won't work, the brake arms are too short to clear the big, thick, tire of a cruiser or Mt. Bike. Ditto for Rat Trap Bars brake levers, they bottom out on a straight bar. Mt. Bike levers work well on cruisers, and hybrids. My Rat Pedal bike has Mt. Bike Bars, levers, and a cruiser saddle. Rides like a 3 speed, climbs like a 10 speed.
