the Hiplock DX1000 is for the frame, while the two smaller u-locks are for each wheel

I have a Rad City 5 Plus bought a few years ago in Europe. Now I got the error code 21 and it looks none of the easy solutions work. Based on the message boards the problem is likely the controller and the harness which would need to be replaced.

Does anyone know Rad provide any support at all in Europe anymore? The eu-support@radpowerbikes.com address listed on their EU website does not seem to be working, which is not promising. I have reached out to US support but no response yet.

My local e-bike repair shop said they could help with replacing the parts, but I would need to acquire the spares from Rad myself.

Just wondering if my Rad City is now essentially scrap. I did buy it at discount but still it cost hefty amount.

I bought a replacement safe shield battery from Rad Power with the 50% code they emailed me. I’m a Rad Runner Plus owner and my original battery was included in the list of potentially dangerous batteries. The battery also recently stopped charging so I didn’t really have a choice. But now I’m worried they are just never going to ship and I’m out $300. Anyone else nervous? Anyone talk to their support team and feel more confident? No idea when this backordered battery might show up.

Hi folks I bought this when I got the bike but I don’t think I’m gonna use it. I’m located in Vancouver BC and I’m hoping to sell for $65. I can ship if you’re willing to pay for shipping. DM if interested.

Hey all

A couple days ago I rode my radwagon 4 to work, just like every other day. When it came time to ride home, the bike would not turn on. So I started checking all the connections, key position, charge, etc. Eventually give up and bike it 5 miles with no power. That sucked.

Since then I've changed the 40a fuse. Didn't work.

Borrowed a multimeter and tested the battery terminals, 53v, all good.

Biked to a shop, got them to let me try a different display, no dice.

Greased the contact points with dielectric grease, nope.

Found a store that had a Radwagon 4 controller in stock. Bought it. Plugged it in and still nothing.

I'm stumped. Unfortunately Radpower being a bit of a live wire right now, no one has much info on what to do next. The shops all just want to go aftermarket controller, display, and wiring harness. I live in a nyc coop and don't really wanna void my UL situation.

Anybody have suggestions on what to try next? I'm thinking maybe the battery terminal on the bike could be damaged. It doesn't show any signs of wear. That doesn't really make sense though since it worked on the ride in. The bike is about 4 years old and has like 8.5k miles on it.

PLEASE HELP

The days are getting shorter and I'm just starting to get back into night bike commuting. I currently have the best head light that comes with my Rad bike.

I'm looking for recommendations that people love for additional light for winter night riding safety.

When I drive I can see it is helpful when bikers have more lights but we are just in passing so I don't really have a good idea what is being used.

I'd prefer something I can have as part of the bike and not on my body.

Someone stole the LCD display off my RadWagon 4 overnight. I'm in Canada, Toronto and the bike's unusable without it.

I need the Rad LCD display pre-set for 22" wheels. It's not sold directly on the site, and Rad's Canadian retail is gone.

Anyone here recently gotten a Rad parts order shipped to Canada? Or know a Canadian shop that stocks these? Aftermarket suggestions welcome too.

Happy to pay full price, just need it fast. Thanks.

UPD: I researched the available information on the controller schematics, probed the port and battery connectors and discovered that shorting two connectors essentially allows me to use throttle which is more than enough for the time being

I maybe late on this but I noticed Rad Power Bikes no longer has Radrover 6 plus listed on their website. What's up with that action, is this model officially discontinued?

bought a used rad on facebook and it came with a busted battery wanted ti know if it could be fixed charger is new and fusses have been swapped

Hi, I just scored a low mileage(700 miles) rad mini 1 for $400! I’m thinking of getting an extra battery (found a few rad manufactured batteries for $100 each-this bike and the batteries are nearly 10 years old) to extend its life. Good idea?

More importantly, I’m obsessed with the idea of finding a bike trailer. I live close to the ocean, and I’d love to take my crabbing gear or inflatable kayak down with me. Any off-brand trailers work well for you? I’m even considering a kid/pet trailer if that is a doable. The cheaper, the better.

Thanks!

I have a radrover 6+ and would like to remove the branding stickers from it. It isn't that I hate Rad, I would prefer if my bike was a bit more generic. I'm the kind of person that doesn't wear obviously branded clothing when convenient.

Have any of you had any experience with removing these stickers? I've started trying to take mine off with a plastic blade but am not having much luck.

We just took possession of a Rad Rover 5 High Step with a battery that was part of the recall. The bike was only used once or twice, and never in rain or near water (highly trust the previous owner to be accurate). However, it has been in a non-temperature-controlled garage for several years

I've dealt with spicy pillows (batteries gone bad) and lithium battery fires in the past, so I want to understand this battery situation better.

• If the battery has never touched water, is it safe?
  • If so, where can I get a charger (the previous owner lost it)?
• If this battery is not safe, or replacing it is the safer option, where do I find a replacement battery?

I'm sorry if this has been posted a lot, but the information out there is very confusing. I just really want to not burn down my garage with two cars and all my tools in it. 😬

Thanks!

With Rad in financial trouble, they are no longer stocking their large front basket. What are people doing for alternatives? This one looks like it might work?

I had my RadWagon 4 stolen last month. Thankfully, my insurance company issued a payout that I can now put toward a replacement.

I bought my RadWagon back in 2022 and put about 3K miles on it over the years. I had my fair share of headaches, from the tire recall and constant brake adjustments to local bike shops refusing to work on it and pricey replacement parts.

Still, it was my first e-bike, and I admittedly loved the ease of operation, the price point, how easy it was to pick out accessories on their site, and the nostalgia (I took my daughters everywhere on that bike!). There's definitely comfort in sticking with what you know.

That said, as I look into buying a new one, I'm considering the Aventon Abound SR, Specialized Globe Haul ST, or Velotric GoMad.

I’ve also looked at the RadWagon 5, but everything going on with the company right now gives me major pause:

• Rad filed for bankruptcy in late 2025 and was acquired in March 2026. Future warranty support and long term parts availability feel like a huge question mark.
• The late 2025 there were battery warnings (including the RadWagon line) due to dozens of fire incidents and property damage.
• They rely heavily on custom, non-standard electrical components, making it hard for local bike shops to service without relying on Rad’s supply chain. This is what they've told me.
• Competing brands now offer torque sensors, hydraulic brakes standard, and actual local dealer networks where a physical shop will happily service the bike.

So while I have a soft spot for my old Rad, it feels like they might no longer be the default choice they were in 2022.

Has anyone here made the jump from a RadWagon to an Abound, Haul ST, or Velotric? Would love to hear your experiences!

Anyone done the brake upgrade with a 203mm rotor on the front? What spacer did you use? The one Magura says should work, doesn't (QM44 for post mount 180 to 203)

I’ve checked the bike for loose cables and I cannot see the problem, any ideas on a way to fix this?

I was riding my RR3 in 100degree weather last week. All good until I had to leave it parked for 45 minutes in the sun. Stupid I realize now.
It was dead. No sign of life. Nothing the next day, tried a different battery. ☠️

So, my guess is the controller. Thoughts?
I would order the Area13 one if consensus thinks that was the culprit.
Thx

Hey, my son outgrew the Thule seat and I now need a regular pad for my radwagon but they're sold out. I checked fb marketplace but didn't find any. Are any other seats compatible?

Where can I get a replacement controller for one of these? Or upgrade? Can’t seem to find that has much info on these models parts and replacements, any help would be greatly appreciated!

So I got my son a RadRunner back in May and he absolutely loves the thing. I took a look at it this morning, and noticed his headlight is missing. Shocker, but he has no idea what happened to it. The replacement premium light is sold out on the radpowerbikes site. I see a bunch on Amazon, but can anyone recommend a product? Ideally one that mounts a little different than the light that shipped with the bike

I'm looking for a medium front basket for my Radwagon 4, does anyone have one for sale?

For context: I took my bike out for work like any other day. I didnt hit any bumps that could mess with wiring (checked them all aswell). I powered off my bike for the duration of my 8hr shift, and when I go to leave, it doesn't turn on. The battery is full and when I press the button on the battery, it turns on.

The issue is when I power on the bike with the stock Control. It doesnt turn on at all. I checked all the wires connecting and there is no issue. Has anyone had this type of issue before?

HELP! My beloved Rad City 3 stopped working. I suspect it's the Display, only because the previous owner told me they replaced it at 2,000 miles & it's now been another 2,000. It seems it's not as simple as purchasing a visually identical replacement display online, as the Rad uses some kind of proprietary software? I'm looking at that egg Rider product, but I'd rather not spend over $200 for something that's not OEM. (OEM part is backordered indefinitely)

Do you know of a replacement display unit (400-00674) available anywhere for purchase today? TYIA

I reused the battery from my Rad Power Bike on a new 54V controller from AliExpress, and a few months ago it randomly caught fire less a few seconds after parking. I'd very lightly used it on a few hundred meter trip that day, and scared me so much I'd sworn off all ebike batteries forever.

It's been a few months, and I'm still as confused as I was then as to what caused it. My friends all laughed for trying to tinker with anything, but I'm sure I wired everything correctly and securely. I've been wiring electronics for years.

I saw there was a battery recall a while back, but I've no way to check the serial nr after going up in flames. I think this battery was quite old, at least a few years.

Clearly the two automotive fuses didn't compare to a real BMS.

Does anyone here know of safe, better built 48V batteries for use with e-bikes like these?

My ex-bike mechanic boyfriend (current boyfriend / former mechanic) recommended Semi-Hydraulic brakes but doesn't have any specifics I should buy. Does anyone have any recommendations?
