Basic rule of reality: The number of ebikes you need is n+1, where n is the number you already have.

The pedal speed is not bad because it has 28" wheels. The problem with the folder that requires the gearing to be changed is that it has the same 14T top gear in a 20" wheel. The gearing was fairly well matched on the one that had the Hailong battery and 27." wheels.

They forgot to mention that it was Harold Wilson's fault. They blamed everybody except him.

Yes, I used to do a lot of humping, but I don't get so much opportunity these days. Is that whyI can't pedal as hard as you. The only time I pedal hard now is when I see them, but then I have to slow down a bit to get the most from it.

That's a good point. You can always overcome weight by adding more power to get more speed uphill, but on a downhill, the heavier bike will always be faster. Having said that, light bikes are better to ride and get out of the shed.

If you have room on your land, get as many panels as you can fit in. Look on Ebay, you can buy complete systems used or new.

Has she got a sister? If so, ask her if she wants to move to Telford.

DYB, DYB, DYB, I'll do my best. I can't wait to try it. Actually, I'm kicking myself because the pain wasn't too bad on day one, so I was going to fit the controller, but after opening the box, I was a little uncomfortable and I figured that it would be better to wait 'til tomorrow when I'd...

That's a very good price, but is a bit low on capacity and power. It'll be OK for charging phones, powering a laptop and lights. If you have a van or boat, or you want emergency power for your house, I think it's worth spending the extra money on a bigger and more powerful one.

Don't worry, it'll be done soon. Sorry to let you down. Everything is done and all the wires are routed through ready to connect to the new controller. It's just the bending down at the moment. I'm not sure whether it's good news, but latest diagnosis is an infection that they're treating with...

I think you have it the wrong way round. The voltage is fixed by the battery, and the current is given by the duty. You talk about average values, but in that case it's better to see each pulse ASAP pulse of energy, height times width giving Joules. The battery voltage is very relevant because...

That's a shame. As he said, you have to be suspicious when things are too cheap, but on the other hand, you shouldn't look a gift horse in the mouth. We did tell him that we tested their cheaper one, and it was excellent.

You need to understand how physics works. You take the energy out of the battery and use it in the motor to assist your pedalling. You can take it out of the battery fast and get a lot of assistance, or take it out slowly and get low assistance. You can't take it out slowly and get a lot of...

My advice would be to get one while you can.

That's it. The sinewave controllers have a different width for every pulse, with the width varying in a sinewave.

But you already decided that you need an ebike rather than an unassisted one. Why would you want an ebike that's the same as an unassisted one? Wouldn't it be easier to stick with an unassisted one?

I lived on my boat for three years. It was brilliant. One year in Bristol Marina and two years in Uphill Boat Yard Western Super Mare

I said that nobody can show anything he did that was actually wrong.

Your right, but you can get a good estimate of how hard you're pushing the batteries from the sag. The heat generated in the battery P=IV. We know the current, so can calculate the heat from the voltage drop. When batteries are pushed too hard, the sag is high, so a lot more heat is generated...

You don't need any special knowhow. A 48v controller and battery are the same as 36v ones. You just connect them together like the 36v system and everything works The only difference is that the motor will spin 30% faster when you want it to, and you get 30% more torque.
