The RadMini 4 from Rad Power Bikes is worth every penny if you’re looking for some quality entertainment on two wheels. Out of the bike’s many impressive features, its monstrous 750-watt rear hub motor with 80 Newton-meters (Nm) of torque is one of its most noteworthy. Simply put: The RadMini 4 is a beast.
Whether you’re riding along a sandy shoreline, riding to work after a snowstorm or racing your friends to the summit of a rocky hill, 750 watts is plenty of power to accomplish your goals. To put that number into perspective, this compact folding bike is actually more powerful than some of the best fat tire electric bikes on the market today. Plus, it means you won’t be left huffing and puffing trying to pedal the bike up a steep hill on your own. A twist grip throttle gives an extra kick of power with a subtle flick of your wrist.
While this fold up electric bike caters to commuters and city dwellers, it has some serious off-road credibility thanks to 20 x 3-inch CST Big Boat puncture-resistant tires. These beefy tires maintain traction on snow, sand and slick roads without adding unnecessary weight — a definite plus if you’re shopping for a lightweight folding e-bike. Want more traction? This bike accepts 4.0-inch fat tires.
A custom Rad Power Bikes RST front suspension fork with 60mm of travel, preload adjustment and lockout erases any doubts about a bumpy and uncomfortable ride. Adding to this bike’s security is a durable hinge mechanism that prevents accidental unlatching.
Numbers matter in the world of fat tire electric bikes. The RadMini4 weighs 67 pounds and supports up to 275 pounds, which makes it one of our favorites for larger riders. Not only does the frame fold up quickly and easily, but the bike also packs down to just 41″ L x 22″ W x 28″ H. You can even raise and lower the handlebar stem for proper storage.
Once it’s properly adjusted, the folding e-bike comfortably fits riders from 5’2″ to 6’2″. A seat height range of 26 to 35 inches accommodates different rider heights. As long as your leg length falls between 24 and 32 inches, you should be able to pedal comfortably on the bike. However, cyclists with a leg length between 24 and 28 inches may contact the frame when standing over it. If this doesn’t sound like fun, a good alternative is the RadMini Step-Thru 2. This electric folding fat bike has a step-through frame for easy on and off, yet is nearly identical in every other way.

There’s also an integrated USB charging port. A backlit LCD display shows the battery level, speedometer, odometer and trip odometer, pedal-assist level, wattage and more. It’s not a color screen but you can clearly see all of your essential riding information.
Full front and rear fenders protect your clothing from spray while making the bike even more stylish. Don’t worry if you’re caught in the rain, as this bike is outfitted with water-resistant connectors and wiring harnesses for extra protection against the elements.
