It's exactly what I've been thinking Fred. I've made a template for my retro cruiser and I have mounted a 3000w hub motor with about 80-90NM of torque and mounted it in a schwinn beach cruiser. So i need a big toque arm and the ones supplied are weak and inferior. Nice work.
Nice torque arm you made there. Regarding the other torque arm you can bolt it directly onto the frame instead of using a hose clamp and put a weld on the pivot point. Then it will work fine.
They were easier to make than I thought but I have vice, files and a grinding wheel etc ,I'd imagine if u made a template it would be easy enough to get a machine shop to knock them up also
@@freds-shed Yeah I thought something was wrong with the dropout of this bike but it turns out the torque arms were hurting and not helping. Clearly don't fit this bike.
Heck yes man, I installed a front hub motor on my existing rwd ebike and I have an aluminum fork. I am making custom welded double sides torque arms so I don’t lose my front wheel when going 35mph down a road haha. Great design you have I like how it fits nicely to the contours of the bike frame
I fabbed my own pair too. They are super beefy. Yours are prettier though. Had to make some custom front fork dropouts as well after the hub motor I put in the front yanked the old ones off.
Fred lad thank you for this video, Ive been breaking my brain thinking about what would be a good way to get a custom torque arm, as paying 40 quid for one off amazon that is pre-machined just isn't an option for me, since I would still have to custom fit it afterwards. I can't believe this hadn't sprung in my mind, just make a little blank and then follow it on a piece of steel, drill out two holes and a 14mm hole for the axle, done. Cheers, and I wish you a healthy 2024.
That's a good cut, you done a grand job considering you used a grinder and file I'm going to try mine with 5 mil stainless with scroll saw 🤦🏼♂️ wish me luck 🍀
well done. As a welder I recommend basic welding skill. A hose clamp will not work with critical failure on these torqe arms you buy on amazon. I had a friend who had a 1000w front hub come out and snap that hose clamp like a paper rip. He was hospitalized for 2 months( front forks dug into ground @ 30mph)...can you imagine? I recommend a steel framed bike as you can weld onto the dropout. Weld 2 coupler nuts on each side of the U. Put the wheel on and then put bolt through as it slides in both nuts on each side. If motor torques it is near impossible for "forks" dropout to bend and/or axle come out. After weld if your sloppy clean up with grinder then put jb weld steel stick putty over welds and morph for a clean look(also seals weld from oxidizing aka rust). Last match the paint. Outcome is industrialized dropout aka motorcycle dropout. I did this with one of those super 73's except it was not a super 73 just the style. Only difference is....its all STEEL. Get a MIG FLUX welder they are cheap and very easy to use.
I wouldn't even trust a 350 watt hub motor in my front wheel, sorry your friend had to learn the hard way, but those mounts are not designed for anything other than letting a wheel free roll on the axle. Mid drive or rear drive really is the only way. Rear being my preference, torque arms are needed and you NEED to mount them the right way, counter to the force of the wheel, or they literally are useless, even if the clamps are not good.
Hi, nice job! I got the part you have shown at the beginning and also found it quite suspicious.. I was breaking my head a full hour trying to imagine how to install it correctly.. And I actually wrote here a long post why this configuration is wrong (axle will try to go out of dropout), but then I got that the bike is standing/hanging upside down and force is going in back direction to that I imagined. That made my post fully incorrect :) Have fun with a bike and be carefull with a power!
I am converting my Phatmoto into a hybrid. The ebike kit did not come with torque arms for some unknown reason, and I doubt they would have worked anyway. I like your idea of using cardboard as a template. I have an old mower blade that I will cut into shape. Thanks for the video.
@@freds-shed I started on the torque arms this morning and worked all day getting it right. I still need to paint them for rust prevention. If I had known that I would have to make so many modifications, I would have just gone to the local bike shop, gotten steel forks, and put on a front hub motor.
Hey mate,please give me a reply ! I had bought battery and electric wheel which is 48v 1000w ! My bike frame size is 21inch ! Anyway i installed everything perfectly,and also i used 2 torque arms ! But still when i ride it,the wheel nuts goes out also when i re-installed it then the wheel goes out. Can u please give me a solution. And please suggest the cycle measurement,which size cycle is perfect.. Pleas
I have a 3000w motor so i definate needed more than just torque arms, yes its aluminium frame ,axel fits snugly knyo metal plate ,no problem amd used it for more than a year now 👍
thanks fred i have exactly the same motor but am trying to use it on a bike (new mind) where the axle stick up about 3mm on the flat edge of the axle (so its not totally sat in deep in the dropouts). should i file it so it sits flush or just leave it be and add two 6mm thick torque arms (the good kind), one either side? Its aluminium frame like your one@@freds-shed
@@freds-shed Yeah, I figured that out by looking at the dropout hole facing the ceiling. That is why I raised the question. I think I know the answer now: you were using your selfie camera, selfie camera will mirror the picture horizontally. The texts on your rim are mirrored as well.

So confused when the bolts were being tightened up anti-clockwise, then I realised the video was flipped 😂
Gets me every time!
What a legend! You know what you are doing and helped me out on my ebike build. Thank you!
Thanks my man ,that comment made my day 👌👍
Wow that looks great that wheel isn’t going no were 😂 lovely job well done pal
Thanks buddy 👍

The welding is definitely a good idea 💡👍👍
I definitely need custom ones. The ones I have literally did the opposite of what torque arms are intended for with a 1200W Rear Hub Motor.

Thanks a mill ,I'd love to see it when it's done ✔
Did you make your yet? Love to see it
Beautiful problem solver One should come with the hub motor

My Uncle has done this to older bicycles he owns .
Nice job good to see another Irish lad tricking with ebikes by the sounds of the accent I’m not from too far away from u 😃
Great buzz in fairness

Glad it worked it for ya my man, mine is flying , no issues at all

Wasn't easy to be honest ,good luck with yours my friend 👍
Sweet job on that Torque arm.. 👏 👌
A lovely job it will make me think about how I will do mine.🍻
Thanks 👍,it worked out great
nice looking plate, good job
Thanks 👍
This is very smart work
Outstanding!
Thank you sir 🙏
Genius
Nice

Great job Fred, im going to habe to do this now as my dropouts have been worn out.
Yea ,it's definitely worth doing buddy 👍 would love to see the end result when it's done ✅
I need something like this for my trek roscoe 7 brilliant idea
Be class wouldn't it 👌
Very nice good idea
Thanks buddy 👍
A sure fix. Great job there. I was wondering about that one.
Thanks very much David, I appreciate the comment 👍

I’ve commented on one of your other videos, I agree with you. How can you have a talk bar, strengthening bar that has a pivot point in the middle?
good video 😁👍
That auld yoke is well built, does it matter which side you make it for?
I made two, I wouldn't risk just one but with a smaller motor it might be ok
Did you do just the one side or do you think it's best to do both sides?
I did both sides buddy 👍
Hey mate,please give me a reply !
I had bought battery and electric wheel which is 48v 1000w !
My bike frame size is 21inch !
Anyway i installed everything perfectly,and also i used 2 torque arms !
But still when i ride it,the wheel nuts goes out also when i re-installed it then the wheel goes out.
Can u please give me a solution.
And please suggest the cycle measurement,which size cycle is perfect..
Pleas
is that aluminium frame? is filing aluminium frame okay if the axle doesnt snugly fit? is it necessary if you have torque arms?
I have a 3000w motor so i definate needed more than just torque arms, yes its aluminium frame ,axel fits snugly knyo metal plate ,no problem amd used it for more than a year now 👍
thanks fred i have exactly the same motor but am trying to use it on a bike (new mind) where the axle stick up about 3mm on the flat edge of the axle (so its not totally sat in deep in the dropouts). should i file it so it sits flush or just leave it be and add two 6mm thick torque arms (the good kind), one either side? Its aluminium frame like your one@@freds-shed
(There's about 3mm of flat edge of the axle sticking out of the dropout). and there is about 1mm of play in the dropout.
let me know, need help please@@freds-shed
why is the brake on the right-side of the bike?
The bike is upside down in the picture
@@freds-shed Yeah, I figured that out by looking at the dropout hole facing the ceiling. That is why I raised the question. I think I know the answer now: you were using your selfie camera, selfie camera will mirror the picture horizontally. The texts on your rim are mirrored as well.
How's it holding up?
Fantastic,I did place a small sliver of rubber in between it and the frame to get it to squeeze up ,but it's perfect 👌
Hey how can I made one please
What part do you need information about and I will try to help
What he say😂😂😂
I said howya James
What thickness is your torque arm ?
I made it from half inch stainless steel Stevo
@@freds-shed It looks more like 1/4 inch to me, maybe 5/16.
