Sasikeibike E7 Electric Bike Review: 1500W Full Suspension Power for All Terrains

The world of electric bikes is growing rapidly, and standing out in the crowd is no small feat. Enter the Sasikeibike E7, a full-suspension, fat-tire folding e-bike built to conquer everything from city streets to rugged trails. With a robust 1500W peak motor, a long-range 52V 20Ah removable battery, and a versatile folding frame, the E7 aims to offer serious performance and comfort for adult riders looking for a blend of adventure, utility, and reliability.

I’ve spent the last few weeks riding the Sasikeibike E7 over a variety of terrains, putting it through its paces in city commutes, on rough mountain paths, and even snowy tracks. From its launch, the E7 has drawn attention for its combination of power, long range, and thoughtful engineering. The brand, Sasikeibike, isn’t just another name in the e-bike market—they’ve been operating out of New Jersey and serving US customers since 2006, which gives an extra layer of reassurance in terms of after-sales support and quality.

The E7 stands out with its UL certification, full dual suspension, and substantial payload capacity, all in a package that folds down for easier storage and transport. But does it live up to the promise, and is it the right bike for you? Let’s dig in.

Is the Sasikeibike E7 for You?

If you’re looking for a powerful e-bike that can handle just about any challenge—be it daily commutes, weekend adventures, or even off-road excursions—the Sasikeibike E7 is built with you in mind. The primary need it solves is providing a comfortable, high-performance ride across diverse terrains, thanks to its combination of a high-torque 1500W peak motor, full suspension, and massive 4.0” fat tires.

This bike is best suited for adult riders who want flexibility: it’s robust enough for larger riders (up to 330 lbs), with a recommended height range from about 5’5” to 6’7”, and it offers a legitimate long-range ride—up to 70 miles per charge with pedal assist. Whether you’re a city commuter, a mountain trail explorer, or someone who wants to get outside regardless of weather conditions, the E7 is ready to perform.

That said, this is not a budget e-bike. While it’s not in the top luxury tier, it is firmly in the middle price range—you’re paying for performance, safety, and thoughtful engineering. If your needs are limited to short, smooth commutes, or you’re on a strict budget, this may be more bike than you need.

In terms of user-friendliness, the E7 is surprisingly accessible. Assembly is straightforward (about 85% assembled out of the box), and the controls are intuitive, thanks to a bright center-mounted color LCD and simple switching between riding modes. Still, beginners who have never used a high-powered e-bike before should start with caution—the acceleration and speed can catch you off guard!

What We Like About the Sasikeibike E7

The first thing you’ll notice is just how solid and confidence-inspiring the E7 feels. The high-carbon steel frame is sturdy and well-finished, and despite being a folding bike, it never feels flexy or cheap. The folding mechanism is smooth but secure, making it practical for those who need to store the bike in a small apartment, car trunk, or garage.

The 52V 20Ah battery is genuinely impressive. Not only does it offer excellent real-world range (I consistently achieved 50–65 miles per charge with mixed pedal assist and throttle use), but it’s also IPX6 waterproof and locks securely in the frame. The removable design means you can charge it in or out of the bike, a real advantage for urban dwellers.

Performance is where the E7 really shines. The 1500W peak brushless motor delivers ample power for hill climbs and fast acceleration, with a true top speed of just over 30 mph in ideal conditions. On steep hills (25–35% grade), the bike maintained momentum without overheating, which is something you just don’t see in lower-end models.

The full suspension system is more than a marketing gimmick. The combination of front and rear shocks, paired with fat 20” x 4.0” tires, absorbs bumps, potholes, and rough trails, making for a smooth ride even when conditions are far from ideal. This makes long-distance rides comfortable and less fatiguing.

Safety features are also well thought-out: dual disc brakes provide strong stopping power, the 600-lumen LED headlight is genuinely bright for night rides, and the reflective strips increase visibility. The LCD display is colorful, easy to read even in direct sunlight, and offers all the essential metrics (speed, PAS level, battery, trip/odo, etc.). Add in the rear rack, fenders, and adjustable seat, and you’ve got a versatile, ready-to-ride package.

What We Don’t Like About the Sasikeibike E7

While the E7 gets most things right, there are a few areas where it could improve. First, weight: at around 70 lbs, this is a heavy bike, even for its class. It’s manageable for most adults, but if you need to carry it up multiple flights of stairs or regularly transport it without ramp access, it’s going to be a challenge.

Folding mechanism is robust but does add some bulk. When folded, the E7 is not as compact as smaller-wheeled folding bikes, mainly due to the fat tires and the sturdy frame. If you’re buying specifically for ultra-compact storage, keep this in mind.

Another minor gripe is the placement of the battery key. While it does an excellent job locking the battery in place to prevent theft, it does not turn the battery on or off. It’s a small quirk, but one worth mentioning for users who are used to a key-switch system.

Lastly, while the motor is powerful, at full throttle it can be a bit loud compared to some premium models. It’s not excessive, but if you value absolute stealth, it’s something to note.

Pros & Cons

Pros	Cons
High 1500W peak motor—excellent torque and speed	Heavy at ~70 lbs—can be difficult to carry
Impressive 52V 20Ah removable, waterproof battery	Folding design still bulky due to fat tires
Real-world range up to 70 miles per charge (PAS)	Battery key does not control on/off
Full dual suspension—superb comfort on all terrains	Motor is louder than some higher-end competitors
4.0” fat tires for stability on snow, sand, or trails	Not a budget option—mid-tier price
Foldable design for easier storage and transport
Bright center color LCD with all essential metrics
UL Certified—reassuring for US buyers
7-speed Shimano gears for versatile riding
Strong dual disc brakes, LED headlight, reflectors

What’s Included?

• Sasikeibike E7 Electric Bike (85% assembled)
• 52V 20Ah Removable Li-ion Battery (with key lock)
• Smart charger (compatible with US outlets)
• Rear rack
• Front and rear fenders
• 600-lumen LED headlight
• Reflectors
• Multi-tool kit for final assembly and adjustments

Opinion:
The included package is both practical and generous. The fact that it arrives 85% assembled saves a lot of time, and the assembly tools mean you won’t need anything special from your own toolbox. The inclusion of fenders and a rear rack is excellent, especially since many e-bikes require you to purchase these separately. If I could ask for one more item, it would be a rear light for night riding, but that’s a minor omission given the solid front headlight and overall thoughtful kit.

Opinion:
The E7’s spec sheet is genuinely impressive, especially considering its price point. Most folding e-bikes with this much power tend to skimp on suspension or battery size, but the E7 is the rare exception that delivers both. The waterproof rating is a valuable addition for anyone who plans to ride year-round. If there’s a weakness, it’s the overall weight—but with fat tires, a large battery, and full suspension, this is simply the price you pay for that level of capability.

Final Breakdown

9.2/10

After weeks of testing, I can confidently say that the Sasikeibike E7 is one of the most versatile and well-engineered folding e-bikes available in its price range. Its combination of power, long range, comfort, and thoughtful extras make it stand out for riders who demand more from their e-bike—whether for urban commutes, weekend trail rides, or year-round outdoor adventures.

The E7 isn’t perfect: it’s heavy, and not the smallest folder on the market, but these are minor trade-offs for what you get. The value is especially strong for those who want a bike that can do it all, with a true sense of safety, stability, and fun.

Do I recommend it?
Absolutely—if you’re looking for a high-performance, long-range, full-suspension e-bike that doesn’t break the bank, the Sasikeibike E7 deserves a spot at the top of your shortlist. Its combination of features, real-world usability, and robust design make it an easy choice for anyone serious about electric biking.
