Concept Viper 18" Boys Single Speed Mountain Bike

Here's another neat little boys bike from the bike boffins from Concept. Simple single speed, the Viper mountain bike looks great and will last for ages. It has full bearings everywhere, wheel hubs, steering, freewheel and bottom bracket. That means it's smooth to ride and requires very little maintenance. It has proper pneumatic tyres and a quality V type braking system. Saddle and handlebars are adjustable so you can fine tune rider position. Finished with a stunning paint job and to die for decals. This one has a real bite!
