You don't have to use a Cyclotricity battery. You can use any 36v battery you want. Whichever you get, it won't have the same connector, but you can buy that connector from Ebay and solder it to your new battery wires so that you can swap it over. It's a very awkward connector, and because of...

The problem is not caused by any current limit because he gets 1000w at low speed, which is consistent with 20A 14S. If none of the setting changes do anything, have a look at the motor connection sequence. Maybe you have a false positive. Try other combinations to see if it sorts it out. This...

Did you try it on all PAS levels? If you have your controller set to speed control on the PAS, each level will give a different speed.

It looks OK. I'd have preferred disc brakes. Don't forget that you need a 328 rpm motor.

Before anything, 20A at 14S is too much for that motor. You'll shred the gears before long. I wouldn't go any higher than 16A. How do you know it's 36v and 201 rpm? What's written on it?

The 750w motor requires a high discharge rate battery. Some of the bundled ones aren't very good.And any of the cheap ones are probably unsuitable too. Look at the battery listings. Any that say they can give 25 amps continuous (not maximum) will be OK. You can't get a quart out of a pint pot...

As I said, power has no influence on speed. You can have a 100w motor that spins to 100 mph or you can have a 6kw motor that won't go past 12 mph.

Yes, but I'm pretty sure that that would make it a 24v one. I can't remember when Panasonic started with 36v, but I never saw one before Bosch bikes started to appear in 2011. I think the first one I saw and tried was in 2013.

If I understand it right, he's simply bipassed the BMS and charging the pack directly, which is OK for a testing, but very dodgy for normal use because if the battery goes out of balance, there's nothing to switch off the charging, so one cell could go very high and catch fire. That's why you...

At 22 mph, it's probably already unrestricted. I've never heard of a bike being restricted to that speed unless it's a 20mph USA version with a bit of tolerance added. You can't make an electric motor go faster by adding more power. Is there anything written on the motor? If it's a Bafang, they...

You can only measure it while charging, which will give you the battery voltage as it rises, so keep measuring while charging. the only problem is that the battery will most likely switch off the charging when the first cell reaches HVC.

You mustn't try to adjust it when you can't measure it. You'll kill your battery and or/set your house on fire.

You can't measure the output voltage of that type of charger. It won't charge until connected to the battery and it'll get pulled down to the battery voltage as soon as it starts charging.

42.0v hot off the charger is good or 41.8v after it's had a chance to settle and balance. The voltage hot off the charger is a measure of how balanced it is. You can often restore balance by leaving it on charge for a long time after you get the green light. Do you always charge until you get...

I tried that, but it didn't work. I bet the controller needs the rotation signal before it'll give power, like any non-zero start controller.

The motor system can fit to just about any bike with a conventional bottom bracket. it's only in recent years that all the weird bottom brackets have become popular. You don't need to spend a lot of money on a donor bike when you fit a motor like a BBS02. Any bike with disc brakes and a triangle...

9A is his input power, so output power would be absolute max 230w, or 60% of what a normal crappy ebike system would give. It's going to be uqivalent to a 24v Cyclamatic, if you've ever tried one of those. It's a direct drive motor, so is probably a lot less effient than that, depending on the...

Not bad, but not particularly good either. Start panicking when it only charges tp 41.0v.

There's no point at all in buying a new bike as a donor for conversion. You can get used bikes for much less than the saving you'd get from using C2W vouchers, and probably a much more suitable bike. From your decription, it's not at all clear to me what you want to use the bike for. Is it...

Don't say I didn't warn you. The net is tightening more every day. Everybody cheered when it was Tommy Robinson and Katie Hopkins. They cheered even more when it was Trump. I wonder how long it'll be before you're protesting rather than cheering...
