Oh the grill looks amazing. Mirrors too, but that grill looks damn good. 🙂
It looks realy realy good only I need airflow so for me they are not so good
Before getting the Bülk, I already have them but I think it would be nice if they were options when ordering the Bülk.
Nice mirrors, where can we get them? Those would look great on my DFXL!
Yes I thing so. You can buy them by Axel Herfurth
@@VelomobileWorld how would I contact him?
Maybe a frame and some thin net would let mor air in.
But then it's not going to be as lasting.
Wel also it does not go so fast
For the overheating on a hill climb , take a frozen camelbag on your belly....I try to lay the frozen camel-bag between the front wheels ove the traverse, just hinking about how can I take the air , which comes in the shell , over the frozen camel bag , over my body ? training in the morning is much effektiv , as training in the evening....real cycle professenls making traing 2 times a day , and sleep between the 2 blocks ;-))
hahaha I work between the training. But not a bad idea a frozen camelbag
Are these only updates of your own bike or also the default for all new Bülks?
These are on my own bike and if I get a lot of requests I want to make it a option on the order list
I like the look of the mirrors Jan, and how do you measure airflow? My guess is that they will create some turbulence and drag, and I was thinking that a conical faring of clear plastic could be formed thin and even enough to be relatively free of distortion, such as vaccumformed clear packaging such as the results this guy is getting: th-cam.com/video/-AAgM6n0tRw/w-d-xo.html - th-cam.com/video/-AAgM6n0tRw/w-d-xo.html
As for your ventilation intake, I recall from similar ventilation air intake hole in light aircraft, rather than covering those inlet holes with a grill, fine wire mesh or stainless steel wool was often installed just downstream from the inlet to prevent bugs from coming in at 200+kph and blinding a pilot, but if you are only concerned for large insects and debris a more less fine screen might stop that without restricting airflow.
I cannot measure the airflow. But I can feel it. I don't have the time beside answering emails, marketing, production, accounting to measure the airflow
@@VelomobileWorldMy Apologizes if I misunderstood, when at 0:34 you mentioned you didn't measure the aerodynamic. I assumed that meant you had some way to measure or estimate drag. If someone wanted to measure drag of the mirrors, one way to get a quick idea of actual drag on small devices like the mirrors, I've done in the past, buy placing the device on about a 2m long aerodynamic profile (i.e, a slim, stick of wood with the edges rounded) and stick it out the sunroof of a car. For precise measurements, measuring the with and without the device attached gives drag of the attachment profile. I built a simple measurement fixture with the long profile on a hinged support with a scale to measure the force about 2ft from the hinge point.
Who cares about the Bülk ? News about the Quest 2.0 or new Version of Quattrovelo oder Alpha 9.2 are much more interesting
For news from Quest 2.0 and Quatttre velo you have to ask velomobiel.nl. Alpha 9.2 is made for realy big people. So I believe less people are intrested. The bulk is a great allrounder for people between 155-195. And lately in a 24H race is also demonstrated that the bulk is also realy fast beside it is a good allrounder. But if you are more specific and send me a email on jan@velomobileworld.com with idea's I am open to listen to them and make a video about it. Have a great day!!
I do care a LOT about the Bülk, it's probably my next velomobile 👍
@@VelomobileWorld You manufacture all velomobiles and should actually be interested in pushing them all in order to generally achieve economies of scale and win customers outside of the forums. I think a lot of innovation came through the Alphas. The best all-round velomobile is not the Bülk but the Quattrovelo (load, suspension,...). I find the Bülk too small for me at less than 190cm. You should revamp your website. The images should accurately match the models and not represent previous prototypes. You should make comparisons between the vehicles, describe them in more detail and support them with photos. You haven't even entered a weight for all models, even though you make them every day. The information from the German dealers on the websites is really bad, if there is anything there at all. You should change that. If you don't read forum posts for weeks and come from the scene, you won't get through here and draw the wrong conclusions.
