How this e-bike scores for different riding styles

Off-Road Adventure

88/100

Excellent off-road capabilities with 4-inch fat tires, full dual suspension, 750W motor with 60Nm torque for 30° climbs, and mechanical disc brakes. The compact size and all-terrain design make it perfect for trail riding and mountain adventures.

Recreational Leisure

80/100

The fat tires, full suspension, and comfortable ride quality make it excellent for casual cruising and beach riding. Three riding modes and pedal assist provide versatility for relaxed recreational use.

Daily Commuting

72/100

The 70-mile range and 21.6 mph top speed make it viable for commuting, but the small 16-inch wheels and compact frame design are less ideal for longer urban commutes. The integrated lights and LCD display add practical commuting value.

High Performance

65/100

The 750W motor delivers solid power, but the 21.6 mph top speed is restricted and below high-performance standards. Good torque (60Nm) for acceleration but capped speed limits thrill-seeking potential.

Compact & Portable

45/100

At 34 kg (75 lbs), it's relatively lightweight for an e-bike, but it's not foldable which significantly limits portability and storage options. The compact 16-inch frame helps somewhat but doesn't match true folding bikes.

Cargo & Utility

35/100

Limited cargo capability with no rear rack, 120 kg (264 lbs) max weight capacity is below average, and the compact frame design prioritizes agility over hauling. Not designed for heavy-duty utility purposes.

Our Verdict

The Spacewalk 16-inch electric bike is a fun little powerhouse that works great for off-road adventures and weekend fun rides. It has a strong 750-watt motor that can climb steep 30-degree hills, plus really fat 4-inch tires that grip well on dirt, sand, and even snow. The big 748Wh battery is one of its best features - it can go up to 70 miles if you pedal along with the motor, or about 50 miles if you just use the throttle without pedaling. That's enough power for a full day of riding. The bike also has shock absorbers on both the front and back wheels, so bumpy trails feel smooth and comfortable. At 75 pounds, it's lighter than most electric bikes, and it has a safety certificate that proves the battery is safe.

This bike is perfect for teenagers and smaller adults who love trail riding and outdoor adventures. If you're between 5 feet tall and average height, and weigh less than 264 pounds, this bike will fit you well. It's also great if you want to ride on beaches, through parks, or on dirt paths in the woods. The price of $547 is really hard to beat - you're getting a powerful motor and huge battery for less money than most other e-bikes. The three different riding modes let you choose if you want to pedal, use the motor, or do both together. The bright front light means you can ride safely when it gets dark.

However, this bike isn't the best choice if you mainly ride on regular streets and bike paths in the city. The small 16-inch wheels and compact design make it less stable at higher speeds on pavement compared to bikes with bigger wheels. It also doesn't fold up, so if you need to put it in your car or store it in a small apartment, you might have trouble. The top speed of 21.6 mph is okay but not super fast - if you want a speed demon, look for bikes that go 28 mph or more. Also, if you weigh more than 264 pounds or need to carry heavy stuff like groceries, you should pick a bike with a stronger frame and higher weight limit.

What We Like

Really strong 748Wh battery gives you up to 70 miles on one charge - that's like riding across town and back several times
Fat 4-inch tires and front and back shock absorbers make bumpy trails feel smooth and let you ride on sand or snow
Only weighs 75 pounds which is lighter than most e-bikes, making it easier to move around or lift if needed
Has a safety certificate (UL2849) so you know the battery won't catch fire and the bike meets strict safety rules
Costs just $547 which is a really good deal for a 750-watt motor and big battery - most bikes like this cost way more

What Could Be Better

Doesn't fold up so you can't make it smaller for your car trunk or tight storage spaces like an apartment
Top speed is only 21.6 mph which is slower than many other e-bikes - some go 28 mph or faster
Can only hold riders up to 264 pounds which is less than bigger bikes that hold 300-350 pounds
Small 16-inch wheels make it less stable on regular roads compared to bikes with bigger 26-inch or 20-inch wheels
Only has basic mechanical brakes instead of fancier hydraulic brakes that stop faster and need less hand squeezing

Standout Features

748Wh battery capacity with 70-mile range

Above average - most e-bikes in this price range offer 500-624Wh batteries with 40-50 mile range

Full dual suspension system with 4-inch fat tires

Exceptional for this price - most budget e-bikes only have front suspension or no suspension at all

Lightweight 75 lbs with UL2849 certified battery

Better than average - most fat tire e-bikes weigh 80-90+ lbs and many lack UL certification

Yes! It has super wide 4-inch fat tires that are made for riding on sand, snow, gravel, and dirt trails. The tires give you good grip and the full suspension helps absorb bumps on rough ground.
