So jay why don't you get someone to come up with a A.C. hub motor that would be the bomb :mrgreen:

No heat issues and better efficient controllers.

Windsurfer, very awesome, have you been to Isola Gabianni? I lived a few miles away from Isola Gabianni for 6 years. Loved it during the summer. Tried windsurfing. Discovered I sucked at that worse than observed trials. That is a super awesome electric surf board. How fast does it go? You Bomber looks right at home next to it.

Sure I've been to Isola dei Gabbiani in Sardegna! It's one of the best Italian spot for windsurfers. But now I have to ask you, wy on the earth did you left that wonderful place where you lived for 6 years :?: I was on holiday in Sardinia many times and every time when I had to go home I took an incredible sadness.
The Lampuga sufboard they say it reaches 50Km/h but for the moment we need to wait for mirror sea water to try that claimed top speed. These days the water is always rough so the board is constantly bouncing.

PS: next time you came back here in Italy I will teach you to windsurf :D

Keeping a motor cool will allow you to run it out side it's efficiency zone for longer, giving that extra torque that us side cover drilling hotrodders crave but it's the well documented story of diminishing returns.
...
If you want to be really hipster get yourself a nice little 408 :P
Not only do the returns diminish as the input power rises, they will diminish to zero - the point at which no amount of extra input power provides any increase in output power whatsoever. At that point you're just torturing the poor motor for no good reason :evil:

Hipster 408? I've got one, been waiting for it to come back into fashion :lol:

Had a ripper of a weekend. Kiwiev and I met up down in Jyndabyne, went for an awesome ride, and did a bunch of work on my Fighter's HS4080 amongst other things.

We managed to replace the axle without too much drama, although it took a huge amount of force to get the busted one out.
Image
Some additional metal was added near the shoulders to add strength and make the fit tighter...it still needs a little filing to make it fit perfect.
Image

Kiwiev also welded on some additional supports to the torque plates.
Image
We cut off the chain tensioners since I don't use them with my derailleur.
Image
Now even if a Hyena rips my nuts of, my wheel ain't falling off! :lol:

Maybe this is something Stealth could do. ;) ;)

I've still got to repair the wires from it falling off, but looking good and I guess that Leaf motor will still be good for lighter duties. :)

Looks like a nice smooth place to hoon around fast. Are they dedicated mtb trails ?
What motors are you running there ?


You can keep your gonads for now :P
But answer me this:
CD.jpg
CD.jpg (104.31 KiB) Viewed 3147 times
A: Have you left heatshrink or some other soft of soft shit on your torque plates ? Any coating that deforms that easily serves no purpose and if anything detracts from its usefulness.

B: What is that monstrosity supposed to do ? :lol:
If you wanted to stop any slight rotational movement of the torque plates all you had to do was insert a thin shim along the top edge in that gap. Or if you're trigger happy with the welder then run a fat bead along the top and then file/grind it back to the exact size of the slot. At this late stage of the game I'd be inclined to do as voicecoils suggested and convert them to pinchers. Easily done, cut the back out of your torque plates, weld them into place and then weld a nut top and bottom to each side of the back of the slot and whack a bolt though to pinch down. Not only would this hold your axle tight but the pinch bolts at the end would stop invisible hyenas snatching your back wheel off as you ride past :P

LOL, Jay, ever the critic.

A) It's called a fresh bit of paint.

B) It's supposed to work that's what...I'm sure your not that blind. Sure, point taken about the gap (although that's from stock), but the bolt/clamp idea doesn't really follow the KISS principal like the current attempt. I'll see how it goes with what we've done, but if it has any issue's the clamp/bolt idea has some merits, Ill admit...it's just a bit complex :)

C) Chill out...we're not all perfect like you Jay. ;)

I'm pretty sure they are dedicated MTB trails...Kiwiev can probably answer that. We were both running HS40 motos. The Giant's was freshly vented making a noticeable difference in temps. :)

Cheers

CD, very nice vid, I really enjoyed watching that. Its like mixing the woods riding up in Idaho with the desert riding I have here in Nevada. Very nice. With your mods, I like the direction you are going, beef up the axle on the shoulder for more contact surface, Isolating the torque blocks movement, that should help.

Hey guys I'll do a Samd here I'm a engineer Mech so the thought was to get the axle to grip further away like a longer wrench to take the extra torque CD is putting thru.
Time will tell if it is beneficial. :D

Hey Rick

The trails are shared for mtb and walkers, we have over 160km of mtb trails within 40 km from home,
Glad you enjoyed the video.

Tough love to inspire you to strive for greatness :P
Kiwi's an engineer, I'm a scientist so I'm programmed to question and critique :)

You guys get points for thinking outside the box, KISS is good and each to their own, but to me it seems you've actually made it needlessly complicated with the external arms. Looking at your pics the centre of the axle hole is barely chewed so it looks like most of the movement is coming from the actual plates having a slight amount of play in the dropout channel. You're going to have to machine that slot longer anyway as soon as your 16mm axle arrives so you may as well just make it open ended and weld it straight to the frame. It'll be stronger, look neater and tidier and be more user friendly.
we're not all perfect like you Jay. ;)
I'm not having a go, I just think if you're going to the effort of doing it, especially given all the hassles you've had, bite the bullet on a permanent solution that will give you no more headaches.
Seeing as you asked :P If this was my fighter and I didnt want to do pinch bolts I'd do it like this:
Weld in the open slotted plate that essentially then becomes a solid rear dropout. Drill 4 holes in it then have a second plate that bolts onto that one capturing the axle and further preventing rotation. Truth be told just a beefy open slot alone would probably work, but with this you can regen until the cows come home.

Sounds awesome! I'm glad someone is getting some use out of the terrain there, from what I've heard the snow season this year was a bit of a non event. It's a bit of a hike for me but one day (hopefully sooner rather than later) I'm planning an ebike road trip (by car/van) from Sydney to Melb and want to do all the cool rides like this along the way :) Just gotta work on a 12v charger now so it recharges off the car between stops - with minor mods I'm hoping the adaptto charging coil plugged into the trailer plug will achieve this.

I 'think' I wore him down...at last a semi respectful reply. :)

I've got a second pair of torque blocks that I'll use for the 16mm axle. No need to change this one again now it's set-up for the 1/2" axle of the HS40. The hole of the torque plate isn't what I meant as being chewed up...it's the dropout slots themselves...mainly on the inside from the shoulders biting into it...but kiwiev also fixed that up with a bit of weld I can grind down flat. :)

I see what you mean about the 2 plates...good idea! I reckon if the current solution doesn't work (although I think it will) then that idea might be the go. :D Thanks for sharing!

The trail was pretty awesome...can't wait to try more...and yeah if your coming down Jay let us know, there's plenty of good trails around my area in southern Canberra also...and I'll still ride with ya. :) 8)

Jay you are are always welcome at our house we live on a farm so a Hyena and a Duck wont be a problem. :lol:
Ask Blake we have plenty of room. It would be good to have a weekend of endless Ebike my wife would love that :mrgreen:

As far as riding you have to be in front I dont want a Hyena chewing my balls off. :D

Hey fellas for all you hot rodeos out there who have modded your bombers battery/engine/controller etc… Do you have to be more careful about heat? allex this is goin out to you specifically but if anyone else cares to join in the convo.. Of course if you go to crazy extremes ins gonna be less reliable I get that but something like what you have done allex how is that for off road aggressive etc..
Thanks..

DANGER DANGER !!!

Had the scare of my life today, coming home in a bit of rain...
Came up a fill negotiating between two cyclist, when the throttle jammed full on...
Luckily as I streaked across an open field, (while being watched by the two cyclists) - I turned the bike off via the key !!!

Holly crap...one hell of a moment !!!

I gingerly turned the key back on but the throttle did nothing...so 8km hardcore bike ride ahead !!!
Luckily the power came on twice for a few hundred meters...which did help ...but again jammed on !

Am I right in thinking this is more than likely the throttle (water inside) and the bike ignores the throttle if the bike is started with full throttle on ?

Anyone else had this ? SCARY STUFF !!!

gees - not fun, is it when the bike decides that you should have auto full throttle - the sequence sounds exactly like when I was caught on my (ex) Bomber in rain. Hopefully you can sort it out, I ended up replacing the controller, then the battery, then selling the bike! :(
Perhaps someone will advise on how to dry it out without permanent damage.

Scary stuff Dunk.

Most ebikes are using a hall effect throttle. The sensor inside is very small with 3 tiny legs right next to each other which if bridged by moisture can put you in a full throttle or no throttle situation.
