Steel frame, steel parts and extremely robust construction make these bikes extremely durable and practically self-sustaining machines. The minimal need for maintenance and servicing only further emphasizes the benefits that singlespeed and fixie bikes have. Occasional cleaning, lubrication and replacement of tires and chains is all this bike requires. Nothing more and nothing less. Everything else is a matter of your choice or taste ....... new grips of different colors or shapes, some cool stickers, different color chains, hubs of different colors, colorful spokes, different steering wheel, some leather saddle, some cool bells, LED lights, flashes or just some super socks, now that you are in this world, the possibilities of "pimping" are limitless and, what's best, nothing is forbidden and everything is allowed. Just the way you want!
