thank you very much for your reply.macribs wrote: ↑Apr 29, 2018 11:22 amEh welcome back?
Nice. I get the idea of this. Making something based on a motorcycle that did an impression on you. That is cool. However my personal #1 is always function gets the high seat. Design is funny that way. Especially if doing your own take on what other done before. On the one hand you like to keep the look, on the other hand, too much focus on look alone might end up being, well not a home run.
The bobber as a concept is cool, and well suited for electrification. But recreating the cylinders/cylinder tops cooling fins? Ok, I guess if you are going to run a liquid cooled motor or controller that could work as a radiator replacement, not as efficient as a radiator but it could still work. As long as you don't run liquid cooling, I think you are sinking countless hours on recreating something that might not be that cool after all when bike is all done and ready. All that time and machining into something that does nothing, has no function,adds nothing to performance, or in any way really. I would frankly just drop the idea of replicating the engine fins, after all you do an electric bobber. Don't be shamed by that. Be proud! Embrace the e-bobber idea. Your design don't need a fake ICE engine, your design is already yours and look great.
Any build likely will eat up man hours like you wouldn't believe. So I guess what I am saying is maybe simplify where simplify makes sense and put those man hours into the rest of the bike keeping overall build moving forward that much faster. Anyway it's your build, you do what makes sense to you. This was just one old mans rambling.
Have you already bought motor and controller? (Those Revolts......hm search the forum for threads about overall quality+performance) If not you could look into other mid drive options. One cool thing that just became an option is to buy motor and controller from Sur Ron, look at the links. That dual motor + dual controller combo seems it should be perfect for your build. Judging by the final price tag on their Sur Ron bikes (3000 $ for complete turn key bike ready to ride) I suspect you might get real good price too. That dual motor should put out real world peak power at 28 kw, continuous @ 16 kw. Double what the dreamers @Revolt claims for the 120 pro. If the Sur Ron dual motor is too much power for you, they got a single motor+reduction @ 14kw peak, 8 kw continuous.
The Revolt over promise and under deliver. One guy is even rebuilding and re wounding the entire motor to get a well working one, to commit to such a time consuming tasks speaks volume of the lack of quality from Revolt. Revolt = Not great motors for e-bikes.
Sur Ron is all the tits these days, lots of forum members have bought their bike, and they all seemed very pleased. So much so that I don't think I've seen so much love since the Stealth Bomber and Stealth Fighter. I have not yet bought one, but it seems that Sur Ron is making a lot of good choices so maybe their motors and controllers turns out to be money well spent. From the looks of the pics in the article it seems the motors got a one step reduction build in.
Check out the Sur Ron motors and controllers. https://evnerds.com/electric-vehicles/e ... companies/
I can see all the pics in this thread.. if you post a reply to the thread and quote the OP then you can see the image source.. the images are posted here : googleusercontent.com ..macribs wrote: ↑May 26, 2018 4:44 pmI checked with 3 browsers, opera, chrome and firefox in windows. No pics.
Then I checked via android on phone. Still no pics. Opera and FF on android 8.1. Them pics you can see, are you sure they are in this post here? viewtopic.php?f=12&t=93996&p=1383035#p1382931 ? I can see the earlier pics in this thread, just the last post made today I cant see the pics.
Did you post the pics on a third party image host website? Sometimes they can do geo blocking, or limit views if you are not paid member. Maybe you can upload them pics to this forum using the Attachements tab under the field where you write your post. Then click "add files".
A lot has happened since then.
thank you for your kind words i really appreciate.JimmyJazz wrote: ↑Jul 22, 2018 1:25 pmWow! You went from designing to fabricating pretty quickly after dreaming about it for years. Congratulations. I've been lurking here for over 5 years and still have only got as far as pencil drawings and mocking up a frame with wood doweling (I have 3 small children consuming all of my time). I love your design, including the controller heat sink. It's a nice postmodern homage to an ICE. I also plan on brazing my frame, though I mean to do tube & lug slipjoints, where there will be a lot of surface area and very tight tolerances (I'm a machinist), so I expect the brazing to be stronger than welds. I wouldn't worry too much about the Revolt situation. Design & fabrication are an iterative process, so I'm sure you'll modify your bike and swap out components that fall short at a later date. Failure is the most important part of learning and progressing. I already have three iterations planned for my bike, so I can concentrate on one difficult subsystem at a time before moving on to the next. I also could not see the photos in the one post (Canada/Windows/Opera), but then could see them in the subsequent posts. Thanks for reposting those. I hope you're having fun building it, and I look forward to following your progress.
