Rad Power is replacing its most popular electric bike — here's what's new
Your first look at the new RadRunner electric bike

Rad Power's RadRunner 3 Plus has long been on our list as one of the best electric bikes; we even gave it a rare 5-star rating for its excellent build, handling, price, and customization options.
But, the RadRunner 3 Plus and its kin (the RadRunner Plus and RadRunner 2) have been out for several years, so the company is refreshing the whole lineup with three new models that promise greater range and a host of new features.
Here's a quick look at the RadRunner, RadRunner Plus, and RadRunner Max, along with what each new model offers.

The RadRunner Range Extender, a second battery that should double the range of the Plus and Max — it's not compatible with the base model — will also be available for preorder on April 30, and will ship in early May. It will cost US $249 | CA $249.

Not surprisingly, the RadRunner Max is the most tricked-out model in the group, with a front suspension fork, a torque sensor and a higher payload capacity.
Other features found exclusively on the Max include built-in Apple FindMy support, digital unlocking (though we still recommend you use one of the best bike locks), and rear turn signals with a rear radar, which will alert you to approaching vehicles.
We do like that all three RadRunner models now come with hydraulic disc brakes — current models have mechanical disc brakes — as well as USB-C charging, and password-protected controls.
Other common features include IPX 6 weather resistance, head- and taillights that turn on and off automatically, and a center color LCD display
As with the previous lineup, the new RadRunners will have 20 x 3.3" tires, though the Max will have slightly thicker 3.5-inch tires.
Both the RadRunner and RadRunner Plus will have a top assisted speed of 20 MPH and a max range of around 55 miles, while the Max's top speed will top out at 28 MPH, with a 60-mile range.
Only the RadRunner Plus and Max will be compatible with the Range Extender battery, which will give each model an extra 65 miles of endurance.
And, as with other Rad Power bikes, the RadRunner lineup will be compatible with all sorts of accessories, from passenger seats (included with the RadRunner Plus), panniers, baskets and more.
Outlook
In all, the new RadRunners aren't a total reimagining of the line, but they do bring some nice improvements. Range has been extended by about 10 miles, load capacity has increased, the brakes are better, and they're getting some niceties built in, such as USB-C charging and Apple FindMy.
Of course, the current RadRunner models aren't any slouches — and are currently being discounted while supplies last. For instance, you can now get the RadRunner 3 Plus for $1,699, while the RadRunner 2 is now just $999. so it might be worth taking a look at Rad Power's deals before deciding if you want an older or newer model.
