Should you buy one?
If you’ll ride it to work five days a week, or you’re replacing a car, the RadRunner 3 Plus is worth it. If you won’t ride it that often, don’t buy it new. I tested this utility e-bike for several weeks with the passenger package, the center console and the front rack. It carried my kids, hauled backpacks and handled mud and gravel well.
What I’d change: the saddle is too flat, the battery is only “semi-integrated” and it uses a cadence sensor. At this price I’d like to see a torque sensor.
Buying note: as of Oct 22, 2026, the RadRunner 3 Plus product page on Rad Power Bikes’ site returns a “page not found” error, so I couldn’t confirm a current price or whether it’s still sold new. If it’s gone, used is the way to go. That’s what I’d suggest for occasional riders anyway.

Source note: the first column is from Rad Power Bikes’ RadRunner 3 Plus product page as saved by a search engine, because the live page returned a “page not found” error on Oct 22, 2026. The second column is what I said in my September 2023 video. The $2,800 is what my test bike came to with all the accessories, in 2023.
Where the numbers are shaky:
- Price. I said the bike was $2,500 plus depending on accessories, and just over $2,800 as I tested it. With no live product page, I can’t give a current price.
- Range. Rad rated it 25 to 45 plus miles. I quoted up to 45 miles. Your range depends on rider weight, cargo, passengers and how much you use the throttle.
- Kickstand. My green bike had a side kickstand. Rad’s page said the other colors came with a center kickstand.
- Rules. It’s a 20 mph bike, but e-bike rules vary by state, so check your state’s e-bike laws.

Motor, battery and pedal assist
The RadRunner 3 Plus has a 750W brushless hub motor and a 672Wh battery. I quoted a range of up to 45 miles per charge, which makes it a good daily commuter.
You get five levels of pedal assist from a cadence sensor with 12 magnets. I’d like a torque sensor at this price. If you want more exercise, turn the motor off or leave it at level one. If you don’t feel like doing anything, just twist the throttle.
Two displays
This is Rad’s newer interface, and you get two displays: one on the left side and one in the center. They’re easy to read and show your speed, the distance you’ve ridden, the battery level and your pedal assist level. When you turn it on, the startup screen spells out RAD, which is kind of cool.
Assembly and accessories
Putting it together is easy. All you really have to do is put on the front tire and the pedals. If you order accessories, which I highly suggest, those you’ll have to install yourself.
Passenger package
The passenger package is my pick. You get clear plastic guards that keep your passenger’s feet out of the wheel. The foot pegs fold up and down and feel really nice and solid.
The passenger handle is nicely integrated. It works great for younger kids riding on the back, since they have something to hold. There’s a handle in front of them and another that wraps around the rear.
Center console
With the step-through frame, I added the center console. It’s like a tank storage box between your legs, and one of my favorite features I’ve had on an e-bike. It’s huge, it fits your wallet, keys or a water bottle, and it locks, so you can leave things in it while you run into a store. It doesn’t get in the way when I pedal; you just step over it.
Front rack
The front rack is great for throwing a kid’s backpack into. If you order it, it comes with an extension for the headlight, so the headlight sits right on the front of the rack.
Lights
The integrated LED lights turn on automatically, and the tail light doubles as a brake light. You all know I love seeing lights built right into the bike.
Cargo and passengers
This is where the RadRunner 3 Plus stands out. The rear rack is rated for 120 pounds, but I think that undersells it. The rear rack is part of the frame, so you can easily carry a full-size adult on the back. Rad’s page listed a 350 lb total payload, so add up your weight, your passenger’s and your cargo before you load it.
Brakes, fork and tires
The brakes are hydraulic discs.
The RST spring fork gives you 60mm of travel, with preload adjustment and a lockout. It makes the bike really nice on gravel, and the knobby tires help too. I’ve taken this bike through mud and gravel, and I was impressed with how it handled.
The tires are 20 inch and puncture resistant. In my video you can see mud spraying up, since I took the front fender off.
The frame and the saddle
The saddle is my biggest complaint. It’s the flattest seat I’ve ever ridden on an e-bike. There’s plenty of cushion, but it’s so flat it almost feels like sitting on squishy cardboard. My butt wants to wiggle around. Most bike seats have some curve that keeps you in place. I’d love to see an upgraded seat on the next version. If you buy one and don’t like the seat, you can find an upgrade on Amazon.
The battery, crankset and slap guard
Rad calls this a “semi-integrated” battery. I feel like a battery is either integrated or it’s not. It looks pretty decent, but if you’re going to integrate the battery, integrate it.
The crankset is nothing to write home about. I do like that Rad added a slap guard on the frame to keep it from scratching the paint. The green on my test bike looks great.
Weather and kickstand
The RadRunner 3 Plus has water-resistant connectors and wiring harnesses, and Rad says you can ride it in the rain.
My bike had a side-mounted adjustable kickstand. If a kid or an adult is climbing on the back, make sure the rider is holding the bike. Don’t rely on the kickstand to hold it up. It can tip over, especially with a little kid climbing on.
Storage: SteadyRack
I store all my e-bikes on SteadyRack wall racks, and they’re awesome. For the RadRunner 3 Plus you need the fat tire version, which doesn’t work with front fenders. That’s why I didn’t have the front fender on. Two racks cost $179 when I made my video, which is rather expensive. They swivel, they’re solid and they’re easy to install. I staggered mine about six inches apart, each on a stud, and it keeps my garage from being a complete disaster.

Source note: RadRunner figures are from Rad’s saved product page. RadWagon 4 figures are from my RadWagon 4 review. Mod Easy figures are from my Mod Easy SideCar review. Range figures are each brand’s top rated number.
The RadRunner is shorter and has a front fork; the RadWagon is the longtail if you need more room on the back. The Mod Easy takes a different approach, with a sidecar for your passenger. For more options, see my best cargo e-bike guide.

How far can it go?
I quoted up to 45 miles per charge from the 672Wh battery. Rad rated it 25 to 45 plus miles.
Does it have a torque sensor?
No. It uses a cadence sensor with 12 magnets and five levels of pedal assist.
Does it have suspension?

Price
As of Oct 22, 2026, Rad Power Bikes’ RadRunner 3 Plus page isn’t live, so there’s no current price I can confirm. When I tested it, the bike with all accessories came to just over $2,800. I thought that was a pretty good price for what you get, if you’ll actually ride it a lot.
