Final geometry & production update

Hey everyone,

It been a long time since the last update, and we apologize for that. We now have everything setup to make all the orders to produce the bikes and frames.

At the moment we are negotiating with our supplier to make the next order of rear frame and fork. Our estimate is that we can make the order in about 1-2weeks.

In the meantime we will make the welding jigs and other necessary things for the production.

Here are the final geometry’s of the frame  52cm 55cm and 57.5cm the effective length is a bit longer on all. Please share your feedback!

    Looks good- what about stem? How long stem is planned to be used on 58 cm frame?

    Just found this project and this seems amazing! Recently had the misfortune of having a bike stolen from a communal bike shed and I’m keeping my other bike, a singlespeed, indoors now so I was wondering if the frames would also be made available? I’ve noticed it’s not an option on the Indiegogo campaign anymore?

      Thank you! Yes, we will have a few more at reduced price. After that prices will go up to retail price.

    Great to see the progress on the bikes!
    How do we backers inform you guys which frame size we desire? Since I believe it was not possible to do that when we chose the bike package.
    Kind regards

    Looks very nice and very interesting!
    Some questions:
    1) What will be the shipping cost to US?
    2) Are there wight limitations to the bike – I am 110kg…but tall 😉
    3) I have some difficulty finding the final break and chain config. of the fixi. Can you share a link?

    …And is the order site still valid?

    Very nice work!

      1) You can see by filling out your address when ordering on Indiegogo.

      2) ~110kg

      3) 46 front and 16 or 18 rear is good.

    Hi Guys,
    can I used this E-Bike-Engine for the fubi-bikes:

    Best regards

      We use 120mm OLD on our frame. It says it has 130mm OLD spacing. It will work, you most bend out the chainstay a bit.
      You most also consider where to but the battery. Otherwise it will work.
