The RadExpand 5 is the latest electric fat tire folding e-bike from Rad Power Bikes

Good news: spring’s almost here. Longer days, better forecasts and a new crop of bikes are en route.

One of the many electric bikes in that crop comes from the fat tire builders at Rad Power Bikes in Seattle. The RadExpand 5 launched on March 9, and its makers tell us that this e-bike is suitable for all types of gnar and improves upon some of Rad Power’s most successful builds to date.

Here’s what there is to know.

The RadExpand 5 picks up where its predecessor, the Rad Power RadMini, left off. According to the brand, it inherits the 2016 RadMini’s folding, space-saving form factor, power, pedal-assist, and notably low price.

In terms of upgrades, there isn’t a ton, but they do sound pretty substantial. Rad says it shaved 5 pounds off the RadMini design, popped some girthy 4-inch all-terrain tires on it, added a rear rack, and retooled its high-rise handlebars, so they’re ergonomic and adjustable.

The gear rack is compatible with any of Rad Power’s utilitarian accessories, which “make cargo-carrying even easier, whether it’s camping equipment or a week’s worth of groceries,” according to the press release.

As for go-potential, this electric fat tire bike gets 25-45 miles of range on a full charge (depends on how much you’re milking the throttle), houses a 672W battery, 48V controller, and 750W brushless geared hub motor.
