Every once in a while my rad mini motor loses power. When applying throttle the motor weakly moves a short distance then stops. If I rotate the rear wheel backwards a little and re-apply throttle the motor does the same thing. On the 2 previous occurrences of this issue it fixed itself but the latest occurrence did not fix itself. After a few days of unsuccessful diagnosis I accidentally bumped the cables under the pedal crank and suddenly the motor started working again.

I inspected the cables and connectors but found no damage and all the connectors were fully seated. I wiggled the cables and connectors, I took the bike for a test ride but the bike worked perfectly again. I suspect that maybe the cable or the connector between the battery cradle and the controller has a problem but until I can recreate the problem I can't be sure of which cable is causing the problem.

What is strange is that when this happens there is no power loss to the rest of the bike. The Display remains on, the lights work, the brake light works when squeezing the brake handles and when applying throttle the display shows wattage being applied to the motor which in itself is kind of strange because the motor isn't running.

Has anyone seen these the same or similar symptoms and figured out what is causing this?

you should put more information about the bike.  what year is the bike?  and which model?  There are more than one model of the city bike.  photos are best to have.  Also Facebook marketplace is a good place to list them too.

Howdy,

I've had the Radrunner for over 2 years now. Overall I'm pretty happy.
However I have a paint issue. I already have some scratches (my fault) and a "bad paint" on the steel fork (please, see picture), that I would like to tackle.

My questions are: does anybody know the green color number by RAL standard?
Does Rad Power Bikes have a paint spray for sale with that paint, may be?
Is it a matte or a satin paint? 

Any ideas about the paint job and repair would be highly appreciated. Thanks.

Are you assuming that your battery is dead? Have you actually used a new charger and it failed to charge?

Have you taken the battery out of the frame and physically inspected it for damages?
If I have to replace the battery and it turned out not the cause of the problem, I would be pretty upset.

With a dog that size, I think you're going about it completely backwards.
This is what you should get:

The dog would probably enjoy it more too, once in a while.

I don't see why they don't make more of them with hitches to the centre of the rear rack. Then you could make tighter turns in both directions.

I've had the exact same problems except I bought two Rad Rover 6 bikes and both of them had the same error and do not produce power. It appears that RPB's is just going to rip us off and let this obvious flaw in manufacturing be the consumers problem.

Thought I'd reach out to you to see if you learned anything. Any resolution?

Used e-bike without the charger?

How confident are you that it was not stolen? A charger is the one part a bike thief would not have gotten.

There are two RadRover 6 plus listed as stolen at https://project529.com/garage

Hi, I just bought a used RadRover 6 plus and the battery was dead. I ordered the proper charger from Rad. I got a really good deal and hoping the battery will take a charge. Looking for feedback.  Thanks

Any suggestions on which trailers work best with the bike brand?

There is a bike trailer with name as  Happy Pet Bike Trailer for medium dog and Hercules bike trailer for Large dog up to 50 kg.

Like new used rad power bike. Selling my rad city step through. Under 700 miles I think or close... $1000 Portland, Oregon
