Whether your summer plans include a lakeside escape, a national park adventure, or as much beach time as possible, a bike is a game-changer. It’s great for cruising the campground, hopping from your rental to the sand, or skipping the hassle of parking altogether. Even better? A bike that does the heavy lifting for you. That’s where electric bikes—and their glorious boost mode—come in handy.

With an electric bike, you can climb steeper trails, haul more gear for a full beach day, and explore off-the-beaten-path attractions without relying on a car or public transit. That’s exactly why Amazon reviewers are raving about Jasion’s almost-sold-out EB5 Electric Bike, a top-rated option that over 700 people just purchased in the past month alone, with a price tag under $400.

Jasion EB5 500-W Electric Bike

The seven-speed e-bike has a 500-watt motor and 360-watt-hour battery with three riding modes: pedal-assist (PAS), full electric, and manual. The booster helps you hit speeds up to 20 miles per hour on flat roads, or cruise up hills at around 5 miles per hour. The ease of design and “efficient” electric assist is what made one shopper call it a “game-changer,” noting that it makes “hills feel flat and distances short” and that it “turned my commute into the highlight of my day.”

As one reviewer put it, the boost “makes mountains into molehills.” Even a ranger from Acadia National Park gave it five stars after using it to ride “dozens of miles of mountainous terrain daily.” Other reviewers say it’s become their go-to for beach days and camping trips. “I’ve been using this on Sanibel Island and can travel all day on a single charge,” another shopper shared. “I tow a chair, cooler, umbrella, etc., to the beach with a bike trailer I bought separately.”

The brand says it can run for 25 to 40 miles (roughly five to six hours) on a full charge. That’ll vary depending on the terrain, but reviewers agree it holds up. “I did a 20-mile trip with hills using PAS 3, and it died just as I hit my destination,” one wrote. “Mind you, I’m a big dude with a backpack, probably totaling around the 265-pound weight limit.”

Jasion recommends this model for riders between 5’4″ and 6’4″. It comes with 26-inch puncture-resistant tires, which some users swap for trail-specific ones. You’ll even find thoughtful extras like a USB charging port, front light, and LCD monitor here.
