Chainless bicycles- look Ma, no grease

Dynamic_bikeGear Live is always finding cool stuff and these chainless bicycles from Dynamic Bicycles are just awesome.  The bikes utilize a driveshaft system that is totally enclosed in the tubes of the bike and the gears are all in the hub.  Since there is no chain there is no grease to get all over your clothes and you won’t get caught in the chain while riding.  More importantly it means you can switch gears while stopped meaning you can always start in the gear you want.  Now this is pure mobile tech.  $579 – $749.
