The Rad Battery Pack

With over a decade of designing and building ebikes under our belts, we know that a high-capacity battery like this isn’t something you cheap out on. We designed and built our batteries using genuine Samsung 35E cells, which are some of the most energy-dense and reliable lithium-ion cells on the market today. These cells have allowed us to build an overall better battery, and at only 7.7 lb, it's one of the lightest and most energy-dense packs on any electric bike.

Reliable, Smooth, Maintenance-Free Hub Motor

Using a brushless direct drive hub motor allows regenerative braking to be enabled as a standard feature. This allows the user to slow down when traveling downhill or coming to a stop while charging the battery in the process. Regenerative braking is automatically activated anytime you engage the brake levers, meaning you can take advantage of this amazing feature without having to do anything extra.

Rad city step through is an amazing bike.

Whst a fantastic bike. My wife enjoys riding bikes but has problems with hills and long distances. Problem solved. We love these bikes. We had a small problem while assembling one of them. I called the help line and they walked me through my problem quickly and efficiently. He even sent me pictures so I could see how it should look. We camp several times a year and cannot wait to take these with us on our next camping trip. If you have been thinking about buying an electric bike look no further than rad power bikes. The price point is perfect and the quality is outstanding. You will not be disappointed.

Pleased! but with suggestions

I love riding my Step-through! So many good features for the price. But a suggestion--give the battery a handle, or some way to grip when removing or inserting. Handling this heavy smooth whale of a battery with sharp edges where it slides in has been a problem for me. It's hard to remove too. With all the warnings about dropping it, give us a little grip to prevent that. In the summer I'll just leave it on the bike more, but have been bringing it inside from the cold garage this winter.

I also have the front rack and small basket, which I wish were a bit less overbuilt and with mesh sides to contain small things better. I needed about an inch more than the seat post it came with allowed, so added the Suntour SP12 and am really pleased with the smooth ride in addition to the extra height.

Love the new bike

With only 150 miles on it, I have come to love this bike. It is a great chick magnet, to share rides when on my RadRover, but truly I just like riding it myself.



The best Island ride

We purchased the rad city step thru and a rad wagon and couldn’t be happier. My husband rides the wagon and I ride the step thru with my 4 year old daughter on back in a kids seat. When she gets taller and her feet can reach the foot rests, she’ll be able to ride on the back of the wagon too without kids seat. These bikes are so much fun, we live up some steep hills and while you still have to put some sweat into it, we have made it up them with our bikes loaded past their weight limit often. Hands down best thing we’ve purchased in a long time. I went from not riding a bike in years to trying to come up with ways to ride places 5-10 miles away daily. What a great way to spend more time outside and with my family. Their customer service is wonderful too.

Really smooth and easy bike

I bought the step through Rad E bike for my husband as a Christmas bike and we love it,

Great Bike and Buying Experience

I have never purchased a bike online without "kicking the tires" first so I was a bit hesitant at first. However, the Rad Power representative was very helpful over the phone and made the buying process easy. It arrived on time and was relatively simple to assemble, especially with the installation video. My wife (Xmas present) loves this bike and I also ordered one (RadRover) for myself. I'll still ride my Kona but now we can go on longer trips together with the e-bikes.

Game Changer

I love my RadCity Step-Thru! I had one issue when it first arrived but Rad totally took care of it. Great support just like others have posted! I recently sold my motorcycle and quickly realized how much I missed cruising around the neighborhood. I take it everywhere now (store, work, school). I love the built-in fenders and racks on this. I load them up and having the step-thru makes it so easy to climb on with a bunch of gear strapped in. Shocks are great and lcd gives me all the great information I need.

Tail light

Tail light is very weak ! Can barely be seen compared to after market lights!


PUT 40 MILES ON MY STEP THRU SO FAR.....LOVE IT. Can,t wait for spring.!
