The Easy Access Comfort Cruiser
The latest iteration of our sleek step-thru commuter bike comes with mounts on its frame for an optional wheel lock, a feature that makes the RadCity Step-Thru 3 even better for running quick errands than any previous model.

What to Measure
Your “real inseam” -- or inside leg length -- is the distance between your body where it sits on your bike saddle and the ground.
This will typically be an inch or two longer than the length of your trousers, but you’ll want to measure to be sure.
You’ll use this number on the chart to get a feel for how the different models will fit you.
How to Measure
Gather the tools needed:
- Medium-width hardcover book
- Tape measure
- A wall you can stand against
- A trusted friend or relative
Wearing your regular riding shoes and with your back to the wall, stand with your feet spread so there is about 7 inches between them - this is about the distance apart your feet would be when straddling a bike with your feet on the ground (standover height).
Place a hardcover book against the wall with the spine of the book facing upward. Slide the book upwards towards your groin until it is solidly against your body. This may be a bit awkward, but is way more comfortable -- and safer! -- than trying to ride a bike that is too big.
If you have a buddy helping you, get them to measure from the floor to the top of the book spine while you hold the book in place. If you’re going it alone, carefully hold the book in place and measure from the ground to the top of the book spine.
A fuel gauge for your electrons.
Pedal Assist Level
The higher the number, the more the motor will boost you when you pedal.
5V, 1 Amp port to charge your phone or portable electronics on the go.
Calculate how many miles you didn't drive this year and how much money you saved on gas.
Can be set to current speed, max speed, or average speed.

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.

"People who might have known about ebikes but struggled to find one that was approachable and well balanced now have a great option."
Looking for something more traditional?
The RadCity 4 is a great option if you want many of the same features as the RadCity Step-Thru but in a more traditional, familiar frame style.
I love riding this bike! I am 65 and when I ride it I feel like I'm 16.
One of the best investments we've ever made!
Most fun I've ever had on a bike!
The fire hit just when I was ready to use it. I will be happy to share my experience when I will have used it for a while.
My wife rides the Rad City Step Thru. We’ve had it a few weeks now and she loves it. Our neighborhood is very hilly and she breezes past me on all the hills. Now that she has the bike she wants to go for an 8+ mile ride after dinner several times a week.
Only regret is the weight.
Got two bikes, wife and I think these are great. Can’t wait to take them on our vacation, ride them all the time where we live, so glad I got them. The only thing we didn’t like is the seats, ended up buying new comfortable ones. GREAT BIKES
Uncomfortable seatOther than that I love it
Simply loving my Step-thru City! Getting in great rides. Wonderful purchase!
We purchased 2 Rad City step thru 3 bikes. We are finding the seats are small and rather hard. We exchanged larger softer seats from our regular Jamis bikes and it feels better on our 80 year old rears. Otherwise Rads are wonderful.
