Re: Don't buy a NineContinents 9C Motor - until you read thi

I wanted to try it for a review, but found out that it would not fit in the 135mm dropout of the bike I intended to use. I have one bike that has 150 mm, but I don't want to rebuild with this one, sorry.

Re: Can't choose a good controller for Crystalyte 5304

You need a torque arm. The fit of the motor depends of the width of your dropouts, the spacer that you might need to align your disc in the caliper, and the gearset that you will use. Normally, you would have 135mm dropouts, and this will leave just enough space for a7 gear freewheel. If you have wi...

Re: QUESTION ABOUT RANGE

Logically, they should do about the same distance, if you run them side by side. Only, one will be able to go 33% faster, to do about 66% of the distance.

Re: Rim Job

Did you really search the internet for 'rim job', you dirty Drunkskunk?

I use the Sunrim BFM, with Kenda Nevegal 2.5. Good match, strongest rim that Sun ever made (disc only), tire wears fast on the street but soft gum sticks like hell. I also use Maaxis Minion 2.7 on Alexrims BHDH, good setup too.

Re: When E-Bikes Attack!

My E-bike did not hurt me, yet.

But dirt bikes sure did: Broken bones, cuts and bruises. I can't count them.
Nothing like the bulls tough. Falling with a bike may be at higher speed; but the bike, unlike the bull, does not come back to try and finish you. :mrgreen:

Re: NewB questions

Well, a ridgid bike can be very uncomfortable at higher speed. You know that above 35mph, the wheels need to be perfectly true and all bearings perfecly tight, for a ridgid bike to be fairly rideable. Some bikes will want to fall apart in small pieces above 40 on a rough road. Full suspension is a m...

Yep, everything you want to do, can be done very well with most smartphones. Lots of people replace them as soon as a new one comes on the market, you can find very good deals on E-bay.

Very interesting project to do with kids at school. Let's hope that some other schools copy your idea.

Re: 12v battery charges in 2 minutes with 2 amp charger

I am far from being an expert in that matter, but here is my logic: When you add a 3rd battery that is discharged with the 2 other that are fully charged, it does not only draw power from your charger, but also a lot of it from the other 2. Then, the time involved depends also on the voltage of the ...

Re: Ae-line 1st build

If I understand well, what you are saying is that feeding more voltage to a 5306 will make it less efficient at lower speed. Then, to be able to ride it slow and keep it from overheating, I would have to give up on top speed. Your solution is interesting then, building a dual voltage setup might do ...

I would not bother the noise, if I'd be riding in the mountain alone. In town, I want to avoid too much attention. My ride is not legal and the police might very well get me out of the road.
