Thx guys! Yeah I will build a 72V battery as soon as i have time and the $$$ for the spare parts needed. I already have some pretty nice prismatic cells laying around, which I'll combine into a pack - again, using my 3D-printer. We already used these cells in the formula student team i've...

23.03.2020 Guys...it's finally done! The build is completed - which means I already tested it on the streets aswell.. It's awesome! :bigthumb: The only annoying thing is: I dont have a 72V battery, which means i dont have the power output I'd like to have. But at least, I can show you the...

I've got news for you :flame: Finally put the Motor in its rim and test-fitted it to the frame. It came out, that the brake disc and its screws wont fit, if you mount it in a 150mm dropout.. so I desgined a spacer and milled it out of aluminium. So if you're reading this, while you*re...

Thank both of you very much! The thing about the shock mounts is: I made simulations for lots of load types. Just looking at the simulation, it should be all fine, as stresses are low enough. But we'll see, how it'll do its job over time. I pretty much tried to go the best "scientific" way...

Hello Guys, maybe most of you have forgotten this project, and I had to pause it for way to much time because of different reasons - mainly time and finances. Neverthenless - its going on now. I ordered the QS205V3 Motor + a suitable Kelly Sine Wave Controller. While the Motor - just looking at...

Hey guys, I'm sorry for not keeping you up to date. In the week after the kebab restaurant 500 degree heat treatment I've finished the T6 treatment in a big oven from a company that produces high-tech limb prostheses. It's always good to have some contacts. Now the frame is sitting in the...

UPDATE 10.09.16 I didn't post sth for quite some time, cause I've got lots of things to do at the moment, (like planning some stuff for university etc..), but still continued this build of course. Like I said in the post before, I had to weld the swingarm still, which worked out pretty good...

UPDATE 18.08.2016 Didn't post sth for quite some time now, so lets go :) I'm nearly done with the swingarm posting this reply, but I will start at the beginning of it of course: First thing, of course was buying new material. After that, I had to cut soooo many things. Its so much work, taking...

UPDATE 29.07.16 It's nearly done! The main frame is nearly finished. Welded the rest of the headtube + the gussets. Came out pretty good. Only thing to do now is the reinforcement for the seat tube (at the cut). I added this part a few days ago when I used the Simulation for structural...

I think you missunderstood me..I dont want to show of or whatever. Maybe my english isn't good enough to express what I wanted, so I'll try again: I don't want this project to fail, I don't want my frames to break. And, I dont want my results be the results of luck or whatever. Thats why I try...

UPDATE 25.07.2016 Today, I've spent several hours "in the office" working on the swingarm. The reason is, that I want to get this thing street legal here in germany, therefore I have to make some frame testing. And of course the people I'm dealing with at "TÜV" should understand that I really...

ok I unterstand your point. But the only thing I will add later are mounts for the box, and these will be soldered (for optical reasons). So temperatures will stay below any critical point. Still, I dont want this thing to break below my *** when im driving at 80 km/h :D

Do you have any links or names I can look for? No Problem! Always a pleasure to help :) I'm even planning building something like a slider with four "wheels" aka bearings just to rest my arm on it and still being able to do a proper slide. I think its quite hard to weld for longer time periods...

Yess of course! Danke :) Well the only reason is, that it's easier to handle in terms of cutting and precision. Stock material is always within + or - 0.05mm and that's really helpful. You don't get this precision with simple steel profiles, except you buy some special stuff but this is even...

UPDATE 20.7.2016 Finally I can post something new in here. Even though I've finished my semster with pretty good grades, still, I don't find much time to continue the frame due to work at the bike shop, other small projects and things with higher priority. You can see the results of 3 hours...
