Nice pictures from before the failure!
OK...NOW i would Like to see someone attempt this with a frock motor mounted in the wheel...Hyena bwahaha seef...
Timma? Rodgah? anyone? c-mon the bars been raised, lets see some collapsed and mangled wheels boiz tehehe
Nice job as always Adam you freakin Rockstar you!!

Hello bzhwindtalker
Your is a very nice project, although is not a bike.... :wink: and I'm so sad that the Swingarm cracks.....Also, It looks you ride pretty hard on the tracks!!!
These tiny tubing for the unsprung shock mount side and mostly the shock position/inclination, with your high pivot point, has never convinced me when looking at your build....but I thought that being steel, It would survive longer...
The unsprung shock mount point moves too much upwards causing a bad shock functioning and an unfavorable ratio. I can see your shock that's slightly bended/convex, but maybe it is a photo distortion.....A more vertical position or an higher shockmount could help.
ABout the way to repair it, that shock mount point protruding from the SwingA. triangle (so there's a lever) is a relatively simple thing I would like to change; extending the upper tubes from the shock mount to the pivot is a good idea....
About the water-cut Swingarm design....Well, we made a Freeride bike that feature an entirely bolted modular Alu swingarm and Frame (it was a 10pcs limited production)....I would say that it isn't an easy road....and It is really hard to get a working design for a total 2d cut, though,
A 3d CNC strategy has been our way with good results....but a crazy expensive way... :wink:
Looking forward to your projects

Yeah indeed let's see some bunny hops with a boat anchor x5 or cromotor in the rear wheel. My rear wheel is super heavy atm but I can run up and down stairs without worrying.
I repaired the swing arm and added two traction struts, it should be quite strong now. The geometry does not look too bad to me really, it uses the same principles that my lapierre blue Fr. I am going in the mountains this weekend, I'll have my new compact camera so I'll shoot some video! I really need to finish the sweeden trip video, I have a few hours of work left...

lookin good man! I need to find some bigger jumps with nice down ramps, most of the ones I find are amateurish downhill ones that kids have built or really big flat lander's....so only a meter of air or so at best.

Hey guys! here's the full movie from the sweden road trip!
I'm not super happy about how it turned, I did not find a reall editing line in the footage we got, but we shoot without knowing what we wanted to do :lol: I don't really have the time to go back througth the footage and correct the editing bugs, but rendering takes 14hours and uploading is about the same deal :| Hope you like it in the end!

To me the best section is the last one when we ride the dh track with Christer in Falun!

very cool! a lot of great footage and the music was good too - and nice combination with the noise of the bikes. definitely worth the wait! looks like you guys had a lot of fun. good luck working on the new swingarm

Without a doubt, your build is amazing. There is only 2 things I would like different on the bike, one personal, one legal. I liked your fsr better because it had pedals, and pedals make a bike legal basically. If you cannot pedal the bike, it makes it a motorbike, so can't be confused as an electric bike by some misinformed police. Otherwise, I *think* it could be lighter for the weight (or maybe I am a hub hater) but wouldn't 80-100 motor be as powerful and lighter? admittedly with extra gearing, so complexity, but personally I feel that is a solvable issue by designers/engineers.
So that's my 2 cents on your build, not exactly as I would do it, but rides how you like it to. I believe in a gng type build that can fit on majority of bikes, use a brushless motor, and be lighter than a hub build. As an industrial design student interested in the final mile issue, I say why make new bikes when we can use our current rides?

This is probably the best design I have seen.
I have tried both hub (X5) and middrive and can say that heavy hub in the wheel is not the way to go. I also had 80-100 as a mid drive and hub drive - many, many problems. So for today, a mid-drive hub is the way to go. I might use a geared bafang motor and make it's shell stationary, but oh well, not a huge issue as we see.
Pedals... hate 'em.

Hey very nice bike and video. For me it looks really lightweight. How much does it weigh?

pretty epic amount of footage you guys must of got, I can only imagine how much time went into sorting through it all. Well done :wink:

Hey Guys thanks for the comments!
As an engineering student, why not make something new? I broke some bike frames in the past. Even DH frames are not strong enough to build powerfull and heavy freeride ebikes IMO.
Cheers! how are your builds coming along?
Actually I'm not so happy with this configuration, it was just something I wanted to try for a long time. The motor takes too much real estate and is a bit heavy to my liking. I really want to find this wider GNG inrunner for the next version!
I did not weigth the bike but I guess ~40kg
We had a 550D (t2i) and a 50D with magic lantern and RAW video recording. 275GB of data

No GNG love anymore except christerljung's Stinky?
Pretty crazy how he exploded his fork.

I don´t think the photos do the actual positions on bike justice. The mx rider is probably putting his weight in the back because of a steep ramp.
However It looks like the footpegs on bzhwindtalkers bike are more towards the front wheel.
Maybe he can tell as where he put them and why?
(The rather heavy engine of an mx bike should add weight on the front and allow footpegs more towards the rear)

Sorry if this has already been talked about, but I want to know if the hubmotor is actually spinning with the motor sprocket. I read up on using a hubmotor as a middrive - but that is using the motor with the axle spinning. If the axle is fixed than the motor should be moving like an outrunner, correct? I can't tell from the videos if the black can is moving. I also couldn't find out how you mounted the sprocket to the motor. It seems like you were easily able to switch the sprocket out from bike to BMX to #35. I know on my hubmotor there are threads on one side and the cassette on the other. Curious to where you added the sprocket.
Your build is where I think the offroad electric mt. bike is headed. MX suspension and tires with the weight of a mt. bike. Having a bigger seat is another nice addition for corners and gives you the extra cushion on landings. I'd love to see someone motocross with a bike seat. Probably not as stealth around the other bikers though - the seat would be a big giveaway you aren't pedaling. I've been riding a 1000w rear hub motor this summer, my first build, and realize some of the faults of a traditional setup. I've broken my rear cassette and am going to have to replace the rim from damage after only a hundred miles or so. Hitting rocks and such at high speeds can do some damage.
So when are these shipping?
