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:

  1. Medium-width hardcover book
  2. Tape measure
  3. A wall you can stand against
  4. 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.

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."

Great Bike at a Great Price!

So far, this is one of the better health/fitness purchases that I have made. While I am by no means a bicycle aficionado, I do recognize things that are either well made and thought out or P'sOS. This bike seems to be well made and engineered. There may be some components that are not the highest quality pieces, but are still good mid line products. Keep in mind that the price on this bike is unbelievably low and ships for free. I think Rad is providing a very nice bike at a very fair price. So far, our weather has only let me get out on the bike 2 times since I bought it, but both rides have been great! The last ride was a 32 mile ride with some serious hills. I used the assist at level 3 most of the time and also found myself using the throttle a few times on the really big hills. I am 210 pounds and found that 32 miles is the range in these conditions. Not bad. I did run completely out of battery about 2 blocks from home. For reference, my wife has a RadRover Step Through (we bought them at the same time). She weighs a lot less than me by around 100 pounds. She still had 2 bars of battery left after this 32 mile ride.

Final words: Buy one. Especially if you are just getting started. Perhaps if you are an avid cyclist and have tons of cash, you may want something else. But, even the components that are not top of the line can be upgraded if you'd like. Oh, I also had an issue with FedEx losing one of the bikes for a couple of days in shipping. 100% out of the control of Rad, but their customer service went well above and beyond what I would have expected and kept in the loop with me and FedEx throughout. That gives me a ton of confidence in the company.

Rad Rover 5 review.

I was impressed the from the moment I opened the box. The riding experience is also MUCH better than I anticipated and it is a very good looking bicycle. I can’t believe how much I am impressed with the 5 level pedal assist.
My only problem is the gears are not meshing properly and after watching the video on how to make adjustments I am making progress on getting the shifting to work better. I am 75 years old with a heart condition and my doctor ordered 20 to 40 minutes a day of exercise so this bike couldn’t have come along at a better time. Thank you, I am very happy with my Rad Rover 5.

New rad5

Not an issue, rides great. Still testing battery usage and mileage. I haven't ridden far enough to use all the battery from full but I have gone 15 miles at a time a The power has held up. I do use pedal assist at varying levels. The fat tires ride so smooth. I have had it on just a few dirt trails, with some hills, and it has performed well. Thx, Frank


So, we have two bikes. I am a huge user. My wife is still getting through the awesome features. No BS. This is an awesome all in one electric bike!!!

Still winter turning to mud season in Vermont, but have a few rides in

Almost got above freezing yesterday so did about 14 miles on the back roads of Lincoln. The power assist going uphill on soft muddy roads was amazing, there would be no way I could have done that myself. Even did a little Forest Service roads with some snow and ice. Looking forward to spring!

Total Rad and still Roving

Had bike three months and still found nothing wrong with bike. Good ride, quality and service. #RadRover


Just what we ordered
Great bike

Like a kid again.

Im 52yrs. In the early eighties I rode a Schwinn World sport delivering newspapers in England. In 1988 I bought a $600 Cannondale and in 1996 a $900 Gary Fisher. I would put this bike in that category of quality. The fat tires have allowed me to float over muddy conditions very well. I am perfectly happy with my purchase nothing I could do to improve the value. The price point is perfect and well thought out and executed. I'm 5 foot 11 160 pounds the bike fits me well it is a big bike my father at 5 foot 5 in is it a little large for him. I would like to see a regearing option as I am mostly interested in just walking speeds on the trail. Will do a 20 mile off road with lots of throttle in hilly South Carolina

Rovin with my Rover

Received my RadRover 5 timely and in good condition. Assembly was not difficult it was actually fun. I have had it for two weeks and have put 150 miles on it. No problems and enjoying every ride. Thank You Rad Power Bikes.
