Rad has lots of parts available that they don’t bother to list on the site. I assume you loosened the caliper mounting bolts and did the whole alignment? Make sure the cable sheathing didn’t jump out at either end. What I find easiest is to set one of the thumb adjustments so it can be...

More info, HG chains are for HG freewheels. Hyperglide. Not on Rad bikes. An HG chain might work on a non HG freewheel but probably not the best shifting. Also heard that some chains off Amazon are too short for Rad bikes. If your chain is worn out the freewheel probably is too. The City uses a...

My 2019 Radcity has about 6k miles and developed side play in rear wheel. I removed the bearings and found the brand Silnt. No that’s not a typo. Sizes are 6001RS and 6904RS. They have black rubber seals on both sides. I ordered SKF on Amazon which was a mistake. The packaging and bearings look...

Good advice. I found tight bearings on my wife’s 2019 City recently and suspect that I overlooked her bike and bearings were set too tight from the factory. 4000 miles and now it has two damaged cone nuts and wear to the hub. The hub is the softest so most bike shops don’t bother with repairing...

No, usually just a charging fuse and an output fuse.

Rad does not sell the cone nuts so I bought a 2019 style wheel, complete with tire, tube, brake disc from them for $120 including tax and shipping.

If you’ve been getting those high wattage readings in PAS 1 or is it called P1 on yours, there is a major problem.

Try C5 = 3 Leave C12 at zero. It will be less power but hopefully in range of the unknown BMS firmware or the BMS’s problem. I’m still saying to put the original controller back in. Then if it fails you can get a battery under warranty. If it does not fail you will have to wonder whether they...

Sounds good but read your third sentence and verify that is what you meant to type. 3rd, not 4th.

Try to find a new BMS and look for bad connections everywhere. Check the key switch under a normal load.

That’s a nice wheel, I found more specs on it though, has 14g spokes. I found that same hub too. Can you use the gauge spokes you want in a hub or is it limited per manuf ?

I looked on several sites and found some that supply almost no details but modernbike.com has a filter system that lets you enter what you want. Only two wheels came up and they ignored my 36 hole request so I assume there are none there. Still waiting to hear back from Rad since the wheel was...

We have two Radcity 2019 versions, wife’s bike at 4000 miles has only had a front wheel cone nut issue due to being too tight and I forgot to check it. Mine lost a motor around 400 miles, controller around 5000 miles. Mine has the Bolton controller/display upgrade and now will blast up hills...

My 2019 Radcity front wheel was somewhat loose so I reclamped the skewer exactly proper and all the way to the stop, really tight as always. It came loose again and again. Can’t see anything wrong with anything, skewer still has the friction pads and all. Then I realized I can make the wheel...

Can’t find these cones. The front axle is undersized for a heavy bike that can have a front rack mounted on. These cones are the size for rear wheels on regular bikes but they don’t have the axle size opening normally found on this size cone. Shopping for axle assemblies and hubs is tough work...

I’m thinking the Rad battery BMS has been changed to prevent using these stronger controllers. This way the batteries last longer especially during the warranty phase for them. They won’t tell you about the BMS, probably just the battery designer knows about it. Glad to hear your tire pressure...

One of our 2019 Radcity has bad axle cone nuts on the front. I’ve looked online but haven’t found them yet. Need 16.9 or 17mm overall diameter, 9mm axle threaded opening, 9.5mm to 11.3mm length (or thickness if holding in hand). The front axle is actually too short on these bikes so the 11.3mm...

They required pictures and/or videos on all warranty issues I had. I don’t think he will get any help from Electro bike world when the problem appears to be battery related because it requires a charge to wake it up after a cut out episode.

You mentioned the bike was newer so I assume under warranty. If so you need to put the original controller and original display back on it. Then if the problem is still there you can get a battery under warranty. They won’t give you any warranty on anything related to your problem if you have...

If your display shows wattage that high it’s not working right because you can’t get 5000 watts from your setup. Need to start with the basics, what tire size is your bike, 2.3in wide or 4in? If 2.3 it’s like the Radcity and should be at least 60psi. Lower pressures affect performance greatly...
