    OpenEbike - open source frame design

    Here is the simulation of both structures. Triangles are in fact stronger. Conditions of experiment Dimensions of beams - 548x60x10 mm Distance of support points - 524 mm Strength applied - 1000 N Weight of a each single beam - 1.005 kg (mass exactly the same) Material for calculations - steel

    OpenEbike - open source frame design

    My bad. I forgot to change sharing settings on these images. I hope they're visible now. As for triangles vs hexagons, this is an opensource project so you're free to change these parts (as soon as we will publish the files). BTW. we've made some structural durability simulations which we will...

    OpenEbike - open source frame design

    Again thanks for the input. The hexagonal shapes are just a matter of design rather than an engineering decision. We're kind of inspired by it so far. I also believe it's very difficult to judge this design based on one poor quality screenshot - I'm attaching some more so you can look at it...

    OpenEbike - open source frame design

    I understand what you mean Chalo. This swingarm is intentionally shaped like this and we have designed specific countermeasures for the forces that will affect it. This is an open swingarm which will allow us to use belt systems instead of chains - I've should have mentioned it in the project...

    OpenEbike - open source frame design

    Hello guys, thank you for your extremely valuable feedback. 1) First of all please help me understand the term triangulation. I'm not an engineer myself and I will have a hard time explaining something to my designers if I don't understand it clearly. 2) Having the frame modular allows you...

    Ok. Well, let's see what we can achieve with just bolts.

    OpenEbike - open source frame design

    Ok, so first of all - this frame is not going to be 3D printed. Steel and aluminum laser / water cutting only. Second of all - this is an early drawing. I'm going to put some more of them soon but the honeycomb structures are going to be covered with 1 mm of flat metal sheet to reinforce it.

    OpenEbike - open source frame design

    Hey all, That’s my first post here - so I’m sorry was not yet properly introduced. Me and my colleagues are in the ebike business for more than two years - building batteries, assembling ebikes, selling parts. We’ve come to a conclusion that there is hardly a choice for us for an e-bike frame...

    Resetting Adaptto Menu Password

    Isn't there a way to reset the password? Are there any Adaptto employees or resellers here who can support me?

    Resetting Adaptto Menu Password

    Hi there, how stupid of me to setup password for menu of my Mini-E controller. I forgot the password and does it mean the controller is bricked? Please help! Konrad
