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.

Love riding again

I have had knee problems for the last few years, which have affected my enjoyment and ability to ride my bicycles. My RadCity step has been a game changer for me. I look forward to my rides again. I must also mention that the staff there has been amazing and if you call, you always get a live human being. Love my bike and a pleasure to workwith you.

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.
