Two Speed Bicycle

The simpler a bicycle's drivetrain is the more I want to ride it, given the choice between multi-geared and single speed I will generally pick the single speed.  Riding a single speed bike is a liberating feeling, it relies heavily on the riders ability to produce power with a limited amount of mechanical advantage. Go faster?, push harder!   

There are times though when having one gear simply is not enough and having the versatility and efficiency of a multi geared drivetrain comes in handy.  What generally happens for me is that I end up riding in 2-3 gears even if I have 18-20 gears available.  Having the ability to have 18 different gear ratios and only using 2 of them seems like a very complex and costly way to achieve what is essentially a 2 speed bicycle.

I've installed a Paul Components Melvin tensioner which allows the use of two front chanrings for a simple but effective two speed drivetrain.  I simply change gears with the front derailleur.

Riding this bike as a two speed has made the experience much more enjoyable for me. Making it simple and still enjoying the benefits of a multi geared bike. The bike is just as versatile as it was with 18 gears.  It does make the engine work harder, which is a good thing.

It rides and feels lighter without the large rear gear cluster.

Sometimes two is enough.
