Hello everyone, I hope you are all in high spirits today.

My Radwagon will not start so I am here to get some advice, I tried reseating all the cables as well as cleaning all the connections with no luck

after hours of Googling several people mentioned it may be the controller. LSW765-28-5FB-19 x19060006322 so I purchased an upgrade kit from...
https://www.affordableebikes.ca/products/radpower-controller-lcd-display-upgrade-35a-controller-kit?variant=43797810905242&currency=CAD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&srsltid=AfmBOoqZPkMWrdcedymHcgCMid-TyEHlfpSTT5YQaPq_wfNEl6JMLY3MHys

I hired Velofix come by today to install the upgraded controller I noted above but they had the same issue I was having before with the new controller kit. I hired them as I wanted paperwork showing I hired a "Professional" Bike repair person to do the installation for warranty.

This didn't fix the issue and I have the same problem. So I am thinking now it may be the wire harness. But I am also thinking if I am going to get a new wire-harness I might as well also finish the upgrades and replace the motor (Shengyi Hybrid) with something better.

The reason why I want to get these upgrades is because this e-bike has a very hard time getting up hills here in Burnaby BC Canada, more often than not I have to get off the bike and walk up the hill.

Any suggestions would be greatly appreciated, I would prefer ordering from a Canadian source vs ordering from our friends south of the border in the USA due to high shipping and border-related fees.

Thanks in advance

No the battery is easy to remove and during my diagnosis I did check the connector for damage of any kind but it's all fine.

Coming up from the states with a RadRover6 Plus... If I stay under 32kph/20/mph, will I be ok with my American spec bike? Is it an issue?

you may have burned the wiring on the cradle where the battery plugs in.  It happened to me.  I tend to use throttle a lot and I have an upgraded controller so I send lots of juice through it. 

I replaced the connectors on both the battery and the cradle. 

Is your battery difficult to remove?  If so then it is a sure sign that you have burned the wiring.  Rads wiring is smaller than it should be.

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.

Quote from: Muskie1 on September 23, 2022, 10:46:57 AMThe problem with a trailer is any axle mount. The warranty is voided.

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?
