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.

Absolutely Thrilled!

We believed we wanted alRad City Step through models but after a trial ride we KNEW these were the bikes for us! We couldn’t be happier with their performance, battery life and variable assist levels. Thanks so much!!

Love my City Step-Thru

I have had my City ST a few weeks and already have over 100 miles on it. Rad customer service is fantastic, I took my CIty ST to my LBS to get a tune up/safety check and they told me I had a bent rotor, I reached out to Rad and they immediately sent me a new one with and allocation for the repair. I would definitely get another Rad bike!

Sooo Much Fun!

Bought the RadCity Step-Thru for my wife's birthday. She has been asking for new bike for couple years, so we could start riding together again (its been 20 years since we road our mountain bikes together). On a whim, she shyly asked if she could get an e-bike. I did lots of research and watched many youtube reviews. Hands down the RadCity had the best options, best reviews and best value. Am I ever glad we made the purchase. Together (me on my RadRover) we have accumulated over 100 miles in first 3-4 weeks. We are having sooo much fun and feeling like kids again. I had a couple of maintenance questions that Rad Support responded quickly. Again, best value e-bike out there.

Great big some minor flaws

Have bought two bikes from rad the most recent was a step thru riding the bike I luv the only problem I have is the reflective white wall on the front tire is out of square which makes the bike look odd going down the road runs fine but looks odd because events have not had a chance to contact rad bikes about this situation again performance of the bike is threat it just looks a little odd going down the road

70th Birthday Present

I'm loving' my new RadCity Step-Thru. I ride it each morning to the gym. OK - it's only a mile, but I like to extend my journey for the love of the ride. I've been experimenting with the different combos of gear selection and degree of power assist. I am enjoy the work out but appreciate the assist when needed. I ESPECIALLY LOVE THE THROTTLE for starting up from a stop. I'm short and the bike is heavy. It's hard to push the pedal with sufficient oomph to keep from wobbling. A little juice from the throttle means I can start up smoothly and not terrify drivers that I might wobble into traffic. I can't praise that feature enough.

Greatest bike ever!

Love my new Rad City Step Through. The assist to pedal is awesome. I now enjoy riding bikes again!!


The bike is fine it's ordering accessories that's very poor. Waited a month for a get basket mount and fenders for rad rover now the say they are avail but have to pay 24 shipping ea can't pick up at. Ballard because they don't have them in inventory but the shipping office is upstairs.duh


Great Bike.... new excitement in biking again!


RadCity Step-Thru

Seriously Life Changing

I love this bike more than words can say. I live in a hilly area that used to make bike riding a huge challenge - especially with little kids. Now, I pop my daughter in the bike seat, and we zip along to the grocery store, play group, or park with no problem. Since getting the bike, there have been dozens of days that I didn't drive my car at all! Didn't even need it. The bike has changed my life for the better. Best purchase I've ever made.
