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.
Shows how much power the motor is outputting at any given time.
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.

"The words 'comfort' and 'fun' rarely go hand in hand, much like 'inexpensive' and 'quality'. The RadRover manages to check off all those boxes which is no small feat."
Looking for something more accessible?
The RadRover Step-Thru 1 is a great option if you want many of the same features as the RadRover but with a much lower stand over height.
