Re: new eZip motor

Do you really need a bike rack for the occasional repairs? It's rare that you would ever need to bring in a whole bike. Wheel need truing? Bring in the wheel. Need new brake pads? Just bring in the frame. Is it just because of the way you've built your bike that it's hard to break down for transport...

Re: How long do your matresses last?

Last one lasted 20 years, even though it was meant to be replaced after 10. I took care of it though. As I have allergies to dust, I had a mattress protector on it, and steam cleaned it once a year. New one is latex topped inner spring. It's really nice. Normally very pricey, but I managed to score ...

Re: UK will be electric bike capital of the world!

If petrol was expensive in Australia as it was in the UK, you wouldn't need to lock down our cities - nobody could go anywhere. The consequence of a country that is 32 times bigger than the UK, but 1/3rd of its population, and a love for big V8s. Oh, and did I mention we have no strategic reserve of...

Re: Undersized Controller ??

The problem of worn springs not letting the clutch engage properly has been well known, and given I drive my Q100Hs up to 1100w, it was a almost considered a consumable. But I've had one where the spring didn't exactly wear, so much as tangle and get crushed under the roller. I couldn't see what was...

Yeah, you've ruled out my first suggestion. I think Amberwolf's suggestion is your next best bet...

Re: Undersized Controller ??

Without seeing or hearing it, I'm going to take a wild stab that it's a badly tuned sensorless start. If it is, it will judder and hum a bit while lurching you forward a little, then be perfectly smooth and fairly quiet once you've moved more than about 1/3rd of a rotation of the wheel. I went to th...

Re: new eZip motor

It seems even the most peaceful parts of the world has turned to violence and chaos. Why, in Australia, we've had a veritable army of women named Karen, not only refusing to wear masks, they keep yelling "I don't consent! I don't consent!" when they are arrested!

Is nowhere safe any more?

Re: new eZip motor

No such thing as a 500w motor. The motor will draw as much power as either the controller will let it, or there is torque to resist. Impossible to tell you what is going wrong without seeing your setup. If it uses an external shunt, it's possible you have the wrong one. Or it's entirely possible tha...

Re: new eZip motor

Really, the best option would be a cheap relay, controlled by a cheap switch, and a cheap fuse in line for short circuit protection. No arcing (that you can see or be exposed to anyway) will last a long time, and won't cost much for reliable quality. Except there's a bit of work and skill involved i...

Re: Motor cover split around freewheel while pedaling.

Have you thought of shot peening your new cover when it comes? Sometimes metal when manufactured does have cracks and inherent stress lines invisible to the naked eye, and cause this kind if failure. Shot peening can fix those. Cryo treatment is also another way to relieve hidden metal stress. It's ...

How are all the projects going LC?

I'm about to do a bit of custom metal work to mount a disc brake kit on a fork that wasn't designed for it. So I guess we are both going down the ghetto bike route now ;)

Re: Any way to convert a rim brake fork to disc brake?

Thanks Markz. Given that I can't get the right fork probably for a couple months, I might do just that. But rather than weld, see if I can do the prototyping on a 3d printer and CNC something up. That way, I don't irrevocably change the fork in case I do want to sell it later, or it doesn't work out...

Re: Any way to convert a rim brake fork to disc brake?

Any ideas? Use a rim brake and a real wheel? They can work as well as or better than disc brakes. Use a good linear-pull brake with high quality pads like Kool Stop, and a booster arch. If that's not gimmicky enough for you, use a Magura hydraulic disc brake. Zipp 302s don't have a rim brake compat...

Re: Any way to convert a rim brake fork to disc brake?

Thanks. But those types of "P clamp" adaptors might work for the rear, but I doubt would be very good for the fork.

Given I now want to avoid RockShox, what's another reputable brand that won't cost me an arm and a leg?

I bought a RockShox Paragon RL "Disc brake" compatible fork from eBay. Everything on the website suggests there is only one model.
