few things to keep in mind when traveling in a storm. 

 

When parking the vehicle, always set the parking brake and place the bow of the Bülk into the 
wind. This prevents the hood from being opened by the wind. Caution: the hood can also be 
pulled up in cross winds. Secure them. 

 

When  getting  out  and  opening  the  hood  with  the  rear  in  the  wind,  the  hood  can  be  yanked 
forward very sharply.  It  is  therefore essential to  control  the movement  of the hood with  the 
hood safety cable. Otherwise the hood can be damaged by the knee lever effect. A hood that is 
torn open by the storm and rolls over can also damage the hinge area of the body. 

 

While driving, there may be a loss of control in a storm if the wind suddenly hits the vehicle 
from side corridors or, for example, oncoming truck traffic causes stalls. Therefore, adjust your 
speed during a storm or refrain from driving. Familiarize yourself with the characteristics of 
the vehicle in a storm. 

 

4.16 Behaviour in the rain 

 

When it rains and is wet, you are much better prepared with a three-lane vehicle than with a one-lane 
one. Nevertheless, here are a few tips. 

 

Especially with new tires you should consider that the grip on a wet road is significantly lower 
than on a dry one. Adjust your speed. 

 

In the wet,  the braking distance is  generally significantly longer and the potential cornering 
speeds are lower. If the rear wheel skids, vehicle control becomes difficult. 

 

Make sure that the water drains in the hinge area and in the hood are permeable. 

 

If visibility with the visor becomes too poor, you should open the visor a little. 

 

 

5. Maintenance and Self-Help 

 
The wear on the drive components is significantly lower than on a normal bicycle. This is because the 
chain and the drive are encapsulated and are therefore very insensitive to the effects of the weather.  
But: The safety-relevant components of the vehicle must be serviced regularly. Contact  your dealer 
and coordinate the maintenance with him. VelomobileWorld provides a series of explainer videos to 
provide customers and dealers with important maintenance information. 
When you are traveling with the velomobile and far away from outside help, it is important to know 
the relevant parts of the vehicle in order to be able to act yourself in an emergency. 
That's why we advise you to spend a while with the vehicle and understand it before you go on a longer 
first tour. 
Fortunately, there is hardly any complicated technology in the Bülk and even laypeople will quickly 
understand how it works. This chapter is intended to support maintenance and repairs. 
   

5.1 Brakes 

 

The SA drum brakes used at the factory are generally very insensitive to weather influences and wear. 
Nevertheless, there are a few things to consider here, because the brakes are vital. 
The tension of the brake cables can be adjusted on the brake levers. It should always be as high as 
possible without the brake starting to drag. A cable with insufficient tension can cause the cable holder 
on the drum brake to disengage if, for some reason, the cable return to the brake plate no longer works. 
We recommend servicing the brakes every 5000 km. 
It should be checked whether the drum brakes are still working properly. To do this, the front wheel is
