Bülk Chain Ring Option

Welcome! On this page you will find details about Bülk Chain Ring Option.

A wide range of gears or a low range of gears?

We don’t know if you’ve just started with cycling a velomobile or if you’ve already been using the velomobile for many years to commute or cycle long distances, but please take the time to read the following and if you think we’re giving wrong advice, let us know, we would like to learn from your experiences.

 

A wide range of gears or a low range of gears?

If you live in a flat area you don’t want to have a wide range of gears. You want a cassette with a low spread, in order you can shift gears with small steps, so you can find the right cadence, which is the best for you.
If you live in a hilly area or mountainous area, you need a bigger spread of gears, otherwise you can’t climb the hill you want.

 

We have made a table for you with which gears you can cycle at what speed.
To make the table easier to understand we fixed a couple of things. It is the best to have a cadence about 90 RPM, if you have a cadence below 90 RPM you can have a higher chance of injuries of your knees. This is a velomobile but also a conventional bicycle.

For the Bülk we have a rear wheel of 584 and we take a 28mm rear tire for the calculations.
