There's a Reason We Call It the Max.
It’s a stylish cargo ebike secretly maxed out with superpowers. A Safe Shield battery, hydraulic disc brakes, radar detection, and torque sensor deliver a ride so smooth and commanding, you’ll never want to ride anything else. Pull off the impossible with a 420 lb. payload and speeds up to 28 mph — then pair it with a Range Extender to unleash up to 125+ miles.
The 90 Nm torque sensor delivers a precise dose of power when you need it most. It makes every ride so comfortable, you’ll barely notice racking up 65 miles. Add a Range Extender and bonus battery (sold separately) to hit our highest range yet: 125+ miles.
Whether you’ve set your speed to a steady 20 mph or notched it up to 28, you can count on fast-acting hydraulic disc brakes, radar detection for approaching cars, turn signals for extra visibility, and the unmatched protection of our Safe Shield battery.
Track your stats in full color, charge your phone on the go, and switch between high and low beams to meet the moment. With passcode-protected security and personalized service alerts, it’s a smarter way to ride.
Lock and unlock your RadRunner Max with your phone, and use the Apple Find My® app to locate it from your iPhone®, iPad®, Mac®, or Apple Watch®.

"I’ve got the regular runner and I still think I preferred over this high tech runner. The high-tech features are nice especially unlocking and locking the vehicle with your phone. Radar is great. Just really hard to maneuver off the road and on the road y’all should give me it for free. Cost a little bit too much for what it isn’t."
"I’ve had my RadRunner Max for about three months and I’m still completely in love. It’s smooth, sturdy, and turns heads every time I ride. I use it constantly around Nashville and even rented the exact same one during my recent trip to Park City because I love it that much. The suspension is amazing, the passenger seat and pegs are perfect for bringing friends, and with the added-on accessories like the large front basket and center console, I can haul groceries, gear, and coffee runs with ease. The Range Extender has been a total game changer for longer days out so I never worry about running out of battery. This bike is the most fun and functional ride I’ve ever owned. If you're thinking about getting one, just do it."
"Been a good bike AFTER we figured out you can’t leave the battery on the bike in the summer. If you are storing this bike outside during the summer the battery will brick on you and the bike will be worthless. The first summer we had no ideal , so we thought the bike was a total loss. 3 months go by it starts to cool down and boom the bike works again. Now my son brings the battery in every day and charges it in his room. Since then the bike has been fantastic. But that is a major problem we have had to work around and shouldn’t have too."
"I came off a radwagon 4. What a great upgrade. Far more maneuverable with the shorter length. Better git and go for hills and stop lights. Range better. Hopefully I’ll never use the LoJack feature."
"My wife and I purchase 2 RadRunners last summer and they are Fantastic Bikes! We ride them everywhere and the power and run time out preform our previous ebikes and our friend's ebikes. If you want quality, power and outstanding customer service then purchase your next Ebike form Rad Power Bikes!"
"I have had my rad for about 3 weeks and it has totally exceeded my expectations."
"So far I've put about 350 miles on my Rad Max. My 1st impression was mostly disappointing due to the poor battery life when the bike is set to 28 MPH, and the power down throttle once it reaches about 40%. Like other reviewers have said the bike is incredibly bouncy and unforgiving on bumpy roads, but that's to be expected with the small wheel diameter, so not a huge surprise, but still disappointing at this price point. Another point of concern is the torque sensor. It is not as responsive and accurate as RAD has claimed. I experience inconsistent ride and response from the torque sensor on almost every ride. I would also note that RAD has advertised this bike as a work horse, with the ability to load up the front and rear of the bike. In reality this is not practical at all and makes the bike extremely unbalanced and difficult to control. The mobile phone TAP unlock feature has NEVER worked and the unlock Bluetooth feature works about 50% of the time, on both Apple and Android. Bike seems to be very sturdy built with quality components despite the fact that it was assembled poorly and had to be triple-checked for the safety and proper assembly despite paying a high high priced fee to have it assembled the RAD shop in Denver. This will probably be the last rat bike that I purchased, which I'm disappointed to say because I've owned several of them. If the rumored bankruptcy of the company, I have serious concerns about ongoing support and maintenance for this bike from Rad."
"I love the flexibility of this bike. I got a small basket up front and a big basket out back. When I want exercise I set the assist to level one. When I'm tired, or it's hot I set the assist to 3 and soft pedal. If I ride where there are no bike lanes and I want to keep up with traffic, level 5 and full steam from the pedals. I've got over 400 miles on it so far and Winter is on the way. We'll see how it does in Montana Winters."
"Incredibly satisfied with this purchase. Also bought the Max Passenger kit and the wheel lock with the long chain. Highly recommended."
"Not happy with the battery life we have a radwagon and older rad bikes that last longer. These have left me stranded a few times w dead batteries. Battery drops fast when it gets to 60percent. So not to happy with them. I thought buying these higher end rads would give us more range. They didn’t"
