@@oliverhofmann2908 gates belt length can’t be adjusted once installed I believe. The bottom bracket needs to move to adjust the reach for different sized riders. You also can’t use belts with derailleurs. The majority of Velomobiles use single sided rear swingarms. That allows changing rear tire/tube without removing the wheel and allows a fully enclosed drivetrain. That would all have to be completely redesigned for a belt drive and you’d lose the easy tire changes, fully enclosed drivetrain, and a bunch of cargo space for a double sided swingarm. With the enclosed drivetrain a properly maintained chain can easily last 5-10,000 miles. A belt drive would increase complexity and mean you’d have to fully redesign all the current Velomobiles. The weight savings wouldn’t be that big when you take into account having to add a rohloff, which also can’t be used with single sided rear swingarms.
Do we have any idea, how hard it will be for a dealer to retrofitt this to the 4 More? I am thinking about getting a Bülk Original (or Bülk Rekord) for speed and a 4 More for utility and I do prefere dual stick steering (still need to try the Bülk version, but I think I would want both rides with the same kind. I begrudgingly understand that you don't offer it from the factory, but I hope to get it anyways, if I should go for it.
@@laurentrouchairoles8271 it is possible to operate tank steering with one hand. The action is not so heavy as you think. However, it is a good idea to have 2 hands for braking. You still have the option for tiller steering. Tiller is my personal preference.

Hopefully, we'll get a sneak peek at some of our velomobiles for Cycle-Con. Bulk Urban #7 for me
I’ll be there in a week and a half for final inspection and will be doing videos just like last time.
Ben will take care of it
Hello!!!☀️
What to say? Just 👍👌
Have a fine continuation and see you.
🙏😌
Thanks, we will!!
@@VelomobileWorld I have no doubt!!!😉👍👌
bravo 😍 j’adore le concept
Thanks a lot
Hello Jan, why not a Gates belt? It's much lighter. Such a long chain also has weight. My idea is a belt drive

belts have higher recistance
Bonjour, est ce que la direction tank (dual stick) pourra etre dispo sur le 4 more?
Bonjour, non, la direction tank ne sera pas disponible pour le Bulk 4M.
I really wish someone would develop a tank steering modification for the DFXL.
Any modifications to the DFXL would come from InterCity Bike. Ymte is in charge of the design for DFXL/DF and Tuna.
Hi the development of DF/DFXL/Tuna is in hands of Intercitybike

Everyting is possible but it is a big job of cutting lamination etc
The problem I see with tank steering is that you are obliged to have two hands to control the velomobile, with a tiler one hand can do it !?

No you don't need both hands but if you want to brake you need both hands
needs steering wheel
well is a bit unpractical with the cycling
