As I said earlier I have not messed with disc magnets or sensors before, or cranks. To get at the disc do I need to take the whole crank out or just the disc side, I bought a puller tool last year but have never used one before, I am just a bit wary of the process, even though I do like to have...

That's made it clear, thanks. I have looked at mine, it is on the side where the gears are. Just rotated the pedals by hand, it looks very much like the magnet disc itself is out of shape with the sensor then being close then further away as it spins. Could that cause my symptoms or would that...

Hi, Thanks for that. Excuse my ignorance, I may have had two bikes before this and have learned some stuff along the way but have never messed about with sensor magnets before. To check what you are saying does that involve removing the crank shaft?

Hi, Thanks for replying. I started of in low gear both times, I also did the throttle but it didn't help. I am quite puzzled because the throttle works great.

Hi, I was hoping someone might know what my problem is, or even if I have a problem. Have just bought a Z6 Zipper I already have a cyclomatic power plus and I had a 20 inch wheel one before that for a very short time. Bought this new at a good price. The thing is it is pedal assist and throttle...

It's amazing what you guys got up to with your mods. How far did you ever get or are you still at, has new technology advanced your efforts. I know "read the forums"

Thanks, I have read that before when I first joined along with many other posts. I did not understand hardly any of it at the time but reading it again it's a lot clearer.

So if I stuck a 48v 18 amp controller on a 36v 250 watt motor that has a 36v battery set up it would get up hills better? Not a full journey of hills just the odd steepish one. Or would a shunt mod on a 36v controller do about the same thing.

So you would not modify an existing controller to get the 20 amps but rather buy one capable of 20 amps then use with your existing 36v 250 watt motor and 36v 10 ah battery, is that right, or can you modify a controller.

So is it the case that most of these mods that are done are purely for speed? What if you wanted one specifically for hills, could a bike be made to do that or would it require a massive battery.

I was talking generally, not about that specific bike. Just as an example, if you had a 36v motor 250watt, 36v battery, what controller could get the most out of that setup... not for me just theoretical.

I have no intention of doing this but does that mean they could handle a souped up controller? Have been doing a bit of reading on electricbike.com regarding souped up bikes, this caught my eye "one of the first steps is to replace the thin wires going into the motor with as thick of wire as you...

I must not have been paying attention. I never heard him mention anything about booster packs. Thought he had done something crazy by just adding more wires to the battery.

Could anyone tell me what this guy has done. Some of you may already have watched it, I would just like to knowif what he has done would work, is it safe etc. It's a bit long winded, if you watch from four minutes in to six minutes you will get the idea. Thanks.

Yes you are right and you also pointed it out a few posts back, I will also, if you recall said I would need to get an motor extension cable, so it's new connectors all round then when I get a battery and suitable controller would probably have to change them again. Your idea about testing...

I know but at this point that's all I want. Philosophy I will leave for another time, i'm busy using my brain on an ebike.

If I cannot do that, do you mean if I am not capable myself of doing that?

Sorry, i must be a right pain. As I have said previously I bought the wheel new but cheap off ebay so before I go any further I just want to see if it works and am unclear how to go about that.

It works fine yes...why? I am just attempting to put a 36v motor, battery, controller ebike together, only to see if it would work, more of a hobby project, no rush etc. To flecc ok so I am not a genius and I won't do that lol

Nearly there with your help... I think. My bike is 24v motor and battery. What I was thinking in my madness is this... Disconnect everything on my bike controller, just leave the battery and throttle connected. Rest the wheel on something close to the battery, something that would let it spin...
