So you absolutely refuse to pump up those tires to the Rad stated must have pressure of 65 psi? I don’t believe it. I bet your kid is riding on about 55 to 60 psi now and finding it much better.

There are supermodels that weigh almost 150 lbs. we are not anywhere near fat for 60 year olds. I told this because AlanB’s son is guess what, 150lbs and riding on nearly flat tires and complaining. Look dudes I found this lengthy thread about his complaints and figured out exactly what is...

She is not short and we are 60 so don’t care about some things that younger people care about. She knows all about this thread and is shaking her head because she has learned when her tires need air just by riding around. She has 3k mikes and I have 4K miles. Rider weight is a very important...

Try it. Prove it to yourself if you have a regular controller. High powered controller’s can be pushed higher to hide the problem. We notice it everytime I forget to top off the pressures. It’s a different bike at low pressure with a direct drive radcity hub which is the main one with a problem...

To prove my point about tire pressure. You guy’s with geared hub motors. Put less than half your usual air pressure in both tires and ride it enough to encounter a decent hill. No one will admit the results but let’s just see. You might get up the hill but it will take a hefty controller to do...

That’s only true at full power and low speed which is not very often if the bike is ridden correctly. Tesla knew that he could use smaller wires because with his system the load would be managed properly and never over current the 3 phases.

Another thing AlanB said that is wrong: “ The battery current gets multiplied, so the motor current is higher than the battery current. To keep from melting this cable they must limit current and therefore torque.” Incorrect. Three phase power on each leg is 1/3 the battery current. That’s why...

:lol: You can lead a horse to water but you can’t make them drink. The issue is that AlanB is analyzing a Radcity without the correct manufactures instructions ie. Tire pressure at 65. Who would do that?

I keep my wife’s tires near 60-65 and she zooms up steep hills on her Radcity. 150lbs. Case closed.

The Radcity does have hall sensors. The cable ends have the 3 large pins but also if you look real close the perimeter has several pads that engage with pads on the other connector. Put in 65psi and ride the bike up a hill. You will be amazed. You will also be amazed on the flats too at all speeds.

Alan B I had to bring this thread back to life so others will know what was wrong with your son’s Radcity performance. You had around 35-40 psi and wondered why the battery performance and climbing speed was bad. The Radcity must have 60-65 psi to get any performance at all unless you weigh...
