Bülk Distance Gear Options

Welke cranks zijn het beste voor jou?

In een velomobiel wil je de ruimte zo klein mogelijk houden, en daar is een goede reden voor. Hoe kleiner de velomobiel, hoe minder luchtweerstand je hebt. Natuurlijk is het volledige aerodynamische plaatje complexer, maar kort gezegd: hoe kleiner een object is, hoe beter het door de lucht beweegt.

Daarom bieden wij kortere cranks aan in een velomobiel. We hebben cranks van 140, 150 en 155 mm beschikbaar. Als je kleiner bent en een kleinere schoenmaat hebt, kun je kiezen voor 155 mm cranks. Als je langere benen en een grotere schoenmaat hebt, is het beter om 140 mm cranks te nemen.

We kunnen je hierbij adviseren — vul je gegevens in en we helpen je verder. Voor meer details klik hier.

Schlumpf Mountain Drive with Multicranks

Verbeterd klimvermogen: de aanzienlijke reductie in overbrenging maakt lichter trappen op steile hellingen mogelijk.

Schakelmechanisme: schakelen gebeurt door op knoppen te drukken die zich aan weerszijden van de trapas bevinden, bediend met de hiel van de rijder.

Multicranks: heeft standaard drie standen voor de gewenste cranklengte.

Opmerking: als je kiest voor Schlumpf Mountain Drive met Multicranks, hoef je geen klein kettingblad te selecteren in de configurator.

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.

12 Speed

• 11-36T (11-12-13-14-15-17-19-21-24-27-31-36 )
• 11-39T (11-12-13-14-15-17-19-21-24-28-33-39)
• 11-52T (11-12-13-15-17-19-22-26-31-37-44-52)

We offer 1×12 speed, this mean one blade in the front and a 12 speed cassette in the rear. This is for those who have a relative low level of hills to climb. For the most 1×12 speed is enough. There is only one but… 12 speed is more sensitive to get it right with shifting.

If you live in a complete flat area like the Netherlands you can drive also very well with 1×11 and a 11-32T cassette.

Here below the table which can help you to choose gear setting.
