Re: Build your own CD battery tab welder for about $100.00+-

I have 3 Monster brand 1 farad caps (two from Texaspyro), and they do go PHWAP and weld nickel shim no problemo. They all measure over 1 farad. But I blew my SCR. Hopefully only half of it is blown, it's two-in-one. I saw a DIY welder on hackaday, where the guy just whacked two big copper blocks tog...

Re: BiGH's Ride!

Come around to my place sometime and we'll fit a cell.

Or drop the pack off at my work one day (Mt Waverley) and pick it up again when it's done.

I have lots of cells, and some shim.

Re: Mark_A_W's DH Team/MAC Shanghai/64v Headway build

No, the motor is completely dead.

I'm slowly building a new battery pack and saving for a new motor (3540). The geared motor experiment is over, the concept is good, but the engineering is not up to the task = they go fast but they break.

Re: Keyne's DH Comp Build

Hi Doc

I'm also a CAD user (it's my job), and I have the DH-Team, which soon will have a HT35 motor too.


I'd really like a copy of those files please! I can add my battery box, and tweak the dropouts, and I'd have a good model of my bike.

I'll send you a PM

Cheers

Re: E-S Stealth Electric Bike Owners

Yeah, but they mount to the bike in completely different ways (usually on the axle). That would be good if John could adapt that to work, but if you are stuck with a traditional hanger then those bomb proof ones won't fit. I broke my derailleur when I tried (and failed..) to beat the railway gate :t...

I've broken a derailleur and I'd still put one a fighter.

It's been done, one of the guys here has a fighter with a derailleur.

Re: UK Giant DH Team eBike - First build!

Nice bike :P

Have you thought about how you are going to mod the dropouts?

And does this frame have 135 or 150mm rear dropout spacing? If it has 150mm you will really struggle to find a motor with an axle long enough to span the distance..

Nah, X5 is too heavy - I want to be able to lift the bike.

I'm thinking about a HS3540 or whatever the new one is called.

Re: Mark_A_W's DH Team/MAC Shanghai/64v Headway build

Well, another day another failure. The BMC V3 freewheel failed, so I got it welded. Then the Keyway failed, so I got the freewheel welded to the axle. But a welded freewheel puts enormous shock loads on the gears, as they never get a break - when you roll down a gutter, the gears get the full force ...

@Mark_A_W : You mean , you welded the axle holes and clamp? Not the steel to the aluminum? I've been thinkin about either welding the axle hole and clamp and grinding 10mm vertical dropouts , or grinding out vertical dropouts from the axle hole , 14mm wide. either way , I'll use steel torque-plates...

Mine is a 600 spring (from memory). I weigh 90kgs and the bike is 36kgs, and I didn't need that much preload for a firm ride. I am bamboozled by the shear number of adjustments on this 6 way shock....most of mine are a midpoint as I didn't know what to do, so any advice is appreciated :) The one rea...

Re: Giant DH-team offroad build. R&D thread

Just some points from skimming through this thread: 1. Twitchy throttle over bumps: A half grip throttle is best here, you can hang on with your little fingers and actuate the throttle with finger and thumb. A trigger throttle would be good too, assuming you can get it to work with brakes and gears ...

Nice bike. I like the colour :)


I have a couple of points/questions:

1. Brake Switches??

2. Legal????


Other than that, carry on, looks good, perfect frame for it.

It's just got a close fitting black mudguard hot glued to the fork arch, right on the wheel.

Looks ok, it's the back one that looks a bit strange.

Re: Mark_A_W's DH Team/MAC Shanghai/64v Headway build

Pack is ~3 years old, had a hard life (sits at 26 amps constant now). I dunno how many cycles, I ride about 3 days per week, charge twice per day....so maybe 900 charge cycles. Well over 10,000k's. The specs on life are bullshit. But these are the very first generation, paper wrapped headway cells.

Awesome video guys.


How did you get the bike over to Perth????


(And with the videos, please ALWAYS remember to do a walkaround of the bike before or after - other than a stack that's the most interesting bit!)


Go easy on the Swans....they are the state emblem or something aren't they??
