I have a belt drive bike. Its friggen awesome. I love it. Its hooked up to a 8 speed internal hub in the rear and the entire bike is a beast. Really the only issue I have with it is the weight. With the internal rear hub and the complexity of the rear bike frame, things get heavy. Also the rear wheel is an unbelievable pain to remove so I added a puncture resistant tube in there, adding to the weight. That said, this bike isn't a go-fast bike. Its more like a pickup truck bike. I can load my paniers down with noms and slap a dirty thirty of Coors Light on the top and as long as I stay in the saddle, its great. Also awesome for general errands and whatnot. Been upgrading the bike after a year to make it more comfortable. I've gotta install a moped-style kick stand, maybe do something with the useless brakes, and a new saddle. I just re-did my paniers and new grips.
Still the SOB is heavy. Putting it on the bike rack sucks and taking it anywhere long distance sucks. However rolling straight out of the garage, I can't think of a better bike. Its SUPER quiet. I sneak up on people then ring my bell and yell at them. Love it. Great for group social rides or going to the hardware store for fittings, screws, etc. The 8 speed hub is great. If I'm loaded down with beer, 1st gear is amazing but most of the time I'm in 3-7th gear.
Except for initial cable stretch, it truly is maintenance free. I dropped it off at the bike shop back in March and the guys were like, it doesn't need anything. Also the rear hub is actually super easy to adjust. I did have some initial problems with the belt tension. Apparently there is a special way for that to be. Seems like few shops and people here on the east coast know what to do. However belt drive is huge out in California. My bike had to actually be shipped in from the Cali warehouse.
Couple years back I was meeting a girl for dinner. Decided to ride big orange. Thought I was hot **** parking that puppy in the bike rack next to all the hipster 30 year old fixie bikes with shot tires. Then this guy shows up with a single speed hard tail 29er belt drive. It was all white and I must say, completely BAMF.
