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.
Gather the tools needed:
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.
Made from a layer of aramid and ceramic particles inside the tire under the tread, the Kenda K-Shield integrated tire liner is a line of defense designed to provide extra protection against punctures from thorns, glass, and other small materials.

While this is my first Ebike, I wanted something that would provide some assistance on the hills of Vermont. I have had a 21 speed hybrid bike for several years, and the hills always turn a glorious ride into a draining chore. I find that the Rad City is a way to take the edge off the steep hills we have here. The quality of the bike is quite good, and I have found the Customer Support team to be exceptionally responsive to any question.
For my type of riding, which is mostly paved or cinder bike paths, and city streets, this is the perfect bike. Others who go off road frequently may wish to select another model. The fat tires seem to have a " cool factor" to them, but I'm not there yet.
Bought this bike for my wife to commute to her various activities within our 55+ community. She loves the sturdiness and the pedal assist. I'm a traditional biker but I'll admit I've "borrowed" it a few times for fun.
I love my Radcity 4 bike with a passion. I live in LA, which is relatively flat, and I'm able to whisk around the city with ease. What I love about the bike are the five-level intelligent assist and the on-demand torque. I feel empowered to explore many miles away from home on my bike. I also like how easy it is to remove the front tire and transport my bike in my car when I want to drive out to the beach and ride along LA's coastline. I visited the showroom and Seattle and got a chance to test a few models, and I like the body size and weight of the Rad City4 over the RadRover, which is better suited for off-road and the RadRunner, which sits lower to the ground.
The only drawback is that when using the pedal assist, it limits you to riding at 20 mph. I wish I could exceed that when pedaling. Besides that, I'm excited to maneuver around LA without hopping in my car and filling up my gas tank.
Disclaimer - I was gifted my bike by Rad Power Bikes for testing and review purposes, but my opinions are my own.
I saw the ads for the RAD bikes and decided to check them out. Recently retired, I have found a need for exercise. The RadCity 4 provides me the exercise and secondary transportation for picking up small things and run those close errands. It is also saving mileage on my car. The pedal assist is great for those times I find myself running low on energy. The bike is very good quality and the assembly was easy. I'm looking forward to years of fun riding my RCv4.
I love my rad bike! It’s opened up the opportunity for new adventures for me as a 70 year old active woman and I couldn’t be happier!
RadCity Electric Commuter Bike Version 4
Absolutely love this bike. Use it daily for commuting purposes and find it well designed; frame is large enough to accommodate a 6'5" man, controls are easy to use, fenders keep you clean and dry, the rack fits aftermarket panniers nicely and the seat is comfy. I've always wanted one but only recently could justify it. It's rad.
It's really great, but just a teency bit too big for me. I really wish they made a smaller version.
With my new RadCity 4 and the longer rides it affords I am discovering bike pathways I previously didn't know existed in our bike-friendly city. Perhaps, more importantly, I'm now able to easily pass cycling college students who used to say, "Who's that old guy struggling on the bike?" but now exclaim, "Who's that rad dude on the ebike?" To belabor the obvious, I'm delighted with my RadCity 4!
I bought this bike so that I could extend my riding range. I’m 62 years old and my knees aren’t what they used to be. Riding my Rad Commuter allows me to traverse any terrain in comfort and ease. I used to have to wait for a day without any wind. Now I can’t wait to ride in any dry condition. I get a great workout with low impact and can ride 30 to 40 miles at a time now. I can’t say enough about how much I like this bike!
