I’m also interested in the electric assist aspect of velos. So if you all do any work in that department I’d love to see what kinds of builds you’ve done, pros and cons of performance and maintenance for different builds, etc.
The challenge is that e-assist is only legal to 15mph in the EU. So you end up with not insignificant weight which is rarely able to be used. It’s an interesting balance to aim for.
Last week I spoke with Wulf Kranijs. I think I write his name correct he developed something like this. If you are intrested to get his contacts please contact me on infov@cvelomobileworld.com
Thanks for the bits you can show us- your "common knowledge" processes are gems of information to many of us who are not in the industry of velomobiles and carbon fibre.
Thanks as always Jan. As a designer and builder myself, (for myself and as cheap as possible!) I can tell you I am watching your videos and any videos I can find about velomobile construction, and composites, in general, to try to get as much information as possible. I know you can't tell your 'secrets' but even so, you revealed you are using Innegra as a sandwich material. This is a type of polypropylene. Well, now I am trying to find some to test! I had even considered using clean (uncoated) nylon peelply as a sandwich material just to hold the bits together in the event of a crash, I had not considered that it might help against the sun's heat. Thanks again anyway, and please keep feeding us little bits of info.
Awesome video! I’d love more technical videos like this. For example, how do you test each velo (Quality Assurance)? How have you designed dynamic aspects like steering geometry, suspension, and aerodynamics?
Awesome video Jan. Love the cutting table with airflow. I’m a surfboard builder and know the process. Do you vacuum bag the lamination of the VM body? Hope so, biiiiiig advantage. Wish you nice summer holiday
Nice. I used to work as a mechanical engineer at Autonational B.V. They make automated machinery for filament winding. Check them out if you ever need to wind something on a mandrel. For the meantime I can't wait on my Snoek to go in production.... (somewhere between #40-50)
Hi Jan, this was a great video. I was wondering if you have done, or could do a video where you check wether drum brakes need changing? I have adjusted my brakes a few times, but not sure I'm getting the breaking distance I should be getting.
Indeed there is a lot of energy in the carbon and in epoxy but if you produce a car there is also a lot of energy in materials and after you use a car it use again much energy. A velomobile is so heavy as a car seat. Probably there goes the same amount of energy in to produce a car seat as a velomobile. Not sure just a thought
If the masses of humanity started screaming for velomobiles, large manufacturers would pour money into factories, and they would spit out a velomobile every minute. Because the actual demand is so low, manual processes are justified because there are enough customers right now who are willing to pay the high price. All the current velomobile builders have the same manufacturing constraints, so none have a significant advantage that they are willing to manifest through lower consumer prices.
Okay. And what is the news? Velomobiles get heavy like cars and you need to put electric engines in to keep still going and after a while the pedals will dissapear because people don't use them.
@@VelomobileWorld I will repeat what I wrote: "If the masses of humanity started screaming for velomobiles..." The point I made was that mass production would greatly reduce the need for manual processes, and with automation, the cost of manufacturing would drop significantly.

Nice workingspace. Looks all good.
Thanks 👍

Hi Elliot, not all my secrets I reveale :-)

There is not so much advantage of vacum the body
Have you ever thought about incorporating NVH techniques from the automobile industry to reduce cabin noise?
Yes we did but ad more material is ad more weight.

We do our best to deliver it ASAP Dennis. Bedankt voor de tip vriendelijke groet Jan
Enjoyed this one, thanks Jan.
My pleasure!
Would love to see how you join the components and keep everything strong and aligned - Much like a jig for bike frames?
I told you already some secrets not all ;-)
Thank you Jan for showing us your exciting velos.
Please keep them coming - and let us know how Holger's German record attempt goes.
Bri
We will you keep informed
Thanks Jan for this video. I understand you don't want to show your secrets. Hartelijk bedankt.....
Wel een aantal maar zeker niet allemaal
Hi Jan, this was a great video. I was wondering if you have done, or could do a video where you check wether drum brakes need changing? I have adjusted my brakes a few times, but not sure I'm getting the breaking distance I should be getting.
I will note it, In a couple of weeks I will shoot again some video's
Nice video! Do you know when the sandwich construction was introduced in velomobiles?
Hi Mark, not the complete part of the velo is sandwich but the middle always is. This is already since approximate 2016
@@VelomobileWorld Very well. So this innovation was introduced by Velomobile World in the velomobile world?
Sounds easy but it's not haha, good one Jan.
Well it is nice that when I started I thought it was easy. Otherwise I don't think I started
A lot of energy inside the carbon blankets.....and in the epoxy..
